Atomic cobalt as an efficient electrocatalyst in sulfur cathodes for superior room-temperature sodium-sulfur batteries
Publisher: Springer Science and Business Media LLC
Date: 04-10-2018
DOI: 10.1038/S41467-018-06144-X
Abstract: The low-cost room-temperature sodium-sulfur battery system is arousing extensive interest owing to its promise for large-scale applications. Although significant efforts have been made, resolving low sulfur reaction activity and severe polysulfide dissolution remains challenging. Here, a sulfur host comprised of atomic cobalt-decorated hollow carbon nanospheres is synthesized to enhance sulfur reactivity and to electrocatalytically reduce polysulfide into the final product, sodium sulfide. The constructed sulfur cathode delivers an initial reversible capacity of 1081 mA h g −1 with 64.7% sulfur utilization rate significantly, the cell retained a high reversible capacity of 508 mA h g −1 at 100 mA g −1 after 600 cycles. An excellent rate capability is achieved with an average capacity of 220.3 mA h g −1 at the high current density of 5 A g −1 . Moreover, the electrocatalytic effects of atomic cobalt are clearly evidenced by operando Raman spectroscopy, synchrotron X-ray diffraction, and density functional theory.

Architecting Amorphous Vanadium Oxide/MXene Nanohybrid via Tunable Anodic Oxidation for High‐Performance Sodium‐Ion Batteries
Publisher: Wiley
Date: 24-04-2021
Abstract: Structural engineering and creating atomic disorder in electrodes are promising strategies for highly efficient and rapid charge storage in advanced batteries. Herein, a nanohybrid architecture is presented with amorphous vanadium oxide conformally coated on layered V 2 C MXene ( a ‐VO x /V 2 C) via tunable anodic oxidation, which exhibits a high reversible capacity of 307 mAh g –1 at 50 mA g –1 , decent rate capability with capacity up to 96 mAh g –1 at 2000 mA g –1 , and good cycling stability as a cathode for sodium‐ion batteries. The a‐ VO x layer enables reversible and fast Na + insertion/extraction by providing sufficient vacancies and open pathways in the amorphous framework, unlike the irreversible phase transition in its crystalline counterpart, while layered V 2 C MXene offers abundant electron/ion transfer channels, which are joined together to boost the electrochemical performance. Notably the improved reversibility and structural superiority of the a ‐VO x /V 2 C nanohybrid are clearly revealed by in situ Raman, in situ transmission electron microscopy, in situ synchrotron X‐ray absorption spectroscopy, and density functional theory calculations, demonstrating a reversible V–O vibration and valence oscillation between V 4+ and V 5+ in the disordered framework, with robust structural stability and unobstructed Na + diffusion. This work provides a meaningful reference for the elaborate design of MXene‐based nanostructured electrodes toward advanced rechargeable batteries.

Sex, Race and ‘Unnatural’ Difference
Publisher: SAGE Publications
Date: 02-2004
Abstract: Theorizing interconnections of sexual and racial differences remains a core problematic within feminist theory. In this article the author argues that these connections might in some cases usefully be understood as constituting a chiasmas. The term ‘chiasmas’ is taken from MichËle Le Doeuff’s analysis of the writings of 18th-century physiologist Pierre Roussel. Le Doeuff argues that Roussel’s understanding of sexual difference is chiastic. An examination of contemporary medical and scientific discourses around the menopause and its treatment through hormone replacement therapy (HRT) takes the argument onto new ground. The author argues here that menopause-related discourses rely on a chiastic logic that connects sexual difference with racial differences. Identification of such logics may prove useful to feminist analyses of specific entanglements of the logics of sexual and racial differences, in contemporary and historical instances.

Missing men, missing infertility: The enactment of sex/gender in surveys in low- and middle-income countries
Publisher: Walter de Gruyter GmbH
Date: 12-2018
Abstract: Although reproduction involves (at least) two sexed bodies, men are often missing from in/fertility research. Surveys such as the widely-used Demographic and Health Surveys (DHS) engage in often unintentional yet highly consequential practices of gendering. Here we identify two processes through which surveys have the potential to render male infertility invisible: defining the population at risk of infertility in an exclusionary way and designing survey instruments to select out some groups/issues. Compiling information about survey s les and inclusion criteria in the DHS, and combining this with a qualitative examination of instrument design, we identify areas of men’s invisibility across time and place. While inclusion of men in DHS s les has increased over time, some men (e.g. single and orced, transgender) remain missing in many survey settings. This is problematic from a reproductive justice perspective. Survey results, which both reflect and contribute to men’s invisibility, are widely used as an evidence-base for family and population policies. Moreover, reproductive health services are only made available to those whose reproductive health needs are recognized men’s exclusion from the reproductive discourse contributes to the stratification of reproduction. Men’s underrepresentation in in/fertility data also reinforces the notion that reproduction is a woman’s domain, and so contributes to a system that places responsibility for reproduction on women. It is vital to explore how gender is enacted or ‘done’ in such research.
Uniform Polypyrrole Layer-Coated Sulfur/Graphene Aerogel via the Vapor-Phase Deposition Technique as the Cathode Material for Li–S Batteries
Publisher: American Chemical Society (ACS)
Date: 10-01-2020
Abstract: The practical application of Li-S batteries is h ered because of their poor cycling stability caused by electrolyte-dissolved lithium polysulfides. Dual functionalities such as strong chemical adsorption stability and high conductivity are highly desired for an ideal host material for the sulfur-based cathode. Herein, a uniform polypyrrole layer-coated sulfur/graphene aerogel composite is designed and synthesized using a novel vapor-phase deposition method. The polypyrrole layer simultaneously acts as a host and an adsorbent for efficient suppression of polysulfide dissolution through strong chemical interaction. The density functional theory calculations reveal that the polypyrrole could trap lithium polysulfides through stronger bonding energy. In addition, the deflation of sulfur/graphene hydrogel during the vapor-phase deposition process enhances the contact of sulfur with matrices, resulting in high sulfur utilization and good rate capability. As a result, the synthesized polypyrrole-coated sulfur/graphene aerogel composite delivers specific discharge capacities of 1167 and 409.1 mA h g

Ovulation monitoring and reproductive heterosex: living the conceptive imperative?
Publisher: Informa UK Limited
Date: 03-03-2015
DOI: 10.1080/13691058.2015.1005671
Abstract: Using biosensors, or devices that provide biological information to users about their own bodies, to map ovulation and time intercourse is a practice of rising significance in economically privileged countries. Based on an ethnographic study of ovulation biosensing, this paper explores the contradictions between device manufacturers' figurations of reproductive heterosex as a natural and pleasurable experience facilitated by fertility monitoring technology, and heterosexual women users' accounts of the pleasures and difficulties of ovulation monitoring and associated sexual encounters. Drawing on Science and Technology Studies and the concept of 'script', we examine the frameworks of action defined by makers of ovulation biosensors and how these are accepted, refused or remade by users. Within the scientific romance configured by manufacturers, reproductive heterosex emerges as exciting and fun, whilst the hard, 'technical' work of conception is done by ovulation technologies. Yet ovulation monitoring is described by many heterosexual women users as an exciting and yet anxiety-producing practice through which they come to know their bodies differently, often through online discussions with other women. Living a 'conceptive imperative', women engaging with ovulation sensing reconfigure their reproductive embodiment and shift their relationship to male partners in ways that reveal heterosexual 'baby-making' as a complex and nuanced practice worthy of critical engagement.
Tanner’s Puberty Scale: Exploring the historical entanglements of children, scientific photography and sex
Publisher: SAGE Publications
Date: 03-2016
Abstract: Globally, increasing numbers of children are thought to be going through early onset puberty. This much debated fact leads to significant concerns about young people’s sexualities, as early developers are thought to be more likely to engage in early sexual activity. Underpinning historical, national and subpopulation (including ‘racial’) comparisons is a standard measurement tool: the Tanner Scale of sexual development. The scale is based on James M. Tanner and R.H. Whitehouse’s ground-breaking longitudinal study of children’s growth undertaken in London between 1949 and 1971. This article explores the largely over-looked and under-theorized significance of the scale’s history, arguing that the study’s focus on children living in an English care institution and its material practices of documenting their growth, including photography, has important ethical and scientific implications for understanding sexual development as a bio-psycho-social process.
Morphology tuning of inorganic nanomaterials grown by precipitation through control of electrolytic dissociation and supersaturation
Publisher: Springer Science and Business Media LLC
Date: 24-07-2019
DOI: 10.1038/S41557-019-0298-6
Abstract: The precise control of the morphology of inorganic materials during their synthesis is important yet challenging. Here we report that the morphology of a wide range of inorganic materials, grown by rapid precipitation from a metal cation solution, can be tuned during their crystallization from one- to three-dimensional (1D to 3D) structures without the need for capping agents or templates. This control is achieved by adjusting the balance between the electrolytic dissociation (α) of the reactants and the supersaturation (S) of the solutions. Low-α, weak electrolytes promoted the growth of anisotropic (1D and 2D) s les, with 1D materials favoured in particular at low S. In contrast, isotropic 3D polyhedral structures could only be prepared in the presence of strong electrolyte reactants (α ≈ 1) with low S. Using this strategy, a wide range of materials were prepared, including metal oxides, hydroxides, carbonates, molybdates, oxalates, phosphates, fluorides and iodate with a variety of morphologies.

General π‐Electron‐Assisted Strategy for Ir, Pt, Ru, Pd, Fe, Ni Single‐Atom Electrocatalysts with Bifunctional Active Sites for Highly Efficient Water Splitting
Publisher: Wiley
Date: 10-07-2019
Abstract: Both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) are crucial to water splitting, but require alternative active sites. Now, a general π‐electron‐assisted strategy to anchor single‐atom sites (M=Ir, Pt, Ru, Pd, Fe, Ni) on a heterogeneous support is reported. The M atoms can simultaneously anchor on two distinct domains of the hybrid support, four‐fold N/C atoms (M@NC), and centers of Co octahedra (M@Co), which are expected to serve as bifunctional electrocatalysts towards the HER and the OER. The Ir catalyst exhibits the best water‐splitting performance, showing a low applied potential of 1.603 V to achieve 10 mA cm −2 in 1.0 m KOH solution with cycling over 5 h. DFT calculations indicate that the Ir@Co (Ir) sites can accelerate the OER, while the Ir@NC 3 sites are responsible for the enhanced HER, clarifying the unprecedented performance of this bifunctional catalyst towards full water splitting.

Abstract: How could social scientists and cultural theorists take responsibility in engaging with science? How might they develop an experimental sensibility to the links between the production of knowledge and the production of existence or forms of life? Critically outlining key fields in the social and cultural studies of science, we interrogate a number of approaches to these questions. The first approach tries to make sense of how science operates in relation to economic, political and cultural forces. The second analyses science as a form of embodied work or practice. The third engages with science as collaborative-collective elaboration of events, ranging across cultural theory, contemporary art and participant ethnographies. This outline sketches a vector of responsibility across this erse range of engagements, suggesting that contemporary movements between science and other knowledges constitute ethical and political imperatives.

Nickel sulfide nanocrystals on nitrogen-doped porous carbon nanotubes with high-efficiency electrocatalysis for room-temperature sodium-sulfur batteries
Publisher: Springer Science and Business Media LLC
Date: 22-10-2019
DOI: 10.1038/S41467-019-11600-3
Abstract: Polysulfide dissolution and slow electrochemical kinetics of conversion reactions lead to low utilization of sulfur cathodes that inhibits further development of room-temperature sodium-sulfur batteries. Here we report a multifunctional sulfur host, NiS 2 nanocrystals implanted in nitrogen-doped porous carbon nanotubes, which is rationally designed to achieve high polysulfide immobilization and conversion. Attributable to the synergetic effect of physical confinement and chemical bonding, the high electronic conductivity of the matrix, closed porous structure, and polarized additives of the multifunctional sulfur host effectively immobilize polysulfides. Significantly, the electrocatalytic behaviors of the Lewis base matrix and the NiS 2 component are clearly evidenced by operando synchrotron X-ray diffraction and density functional theory with strong adsorption of polysulfides and high conversion of soluble polysulfides into insoluble Na 2 S 2 /Na 2 S. Thus, the as-obtained sulfur cathodes exhibit excellent performance in room-temperature Na/S batteries.

Messengers of stress: Towards a cortisol sociology
Publisher: Wiley
Date: 05-2021
Abstract: In 2008, Timmermans and Haas called for a ‘sociology of disease’ to develop and challenge the sociology of health and illness. A sociology of disease, they argued, would take seriously the biological and physiological processes of disease in theorising health and illness. Building on two decades of Science and Technology Studies and feminist work on biological actors such as hormones and genes, we propose a ‘cortisol sociology’ to push further at this argument. As a ‘messenger of stress’, cortisol is key to understanding human and non‐human health as a biosocial phenomenon. We argue that sociologists should engage with cortisol through critical yet open‐minded reading of the relevant science and critical triangulation studies, and by tracking cortisol’s movements from science into public worlds of biosensing and self‐monitoring.

Nanocomposite Materials for the Sodium–Ion Battery: A Review
Publisher: Wiley
Date: 20-12-2017
Abstract: Clean energy has become an important topic in recent decades because of the serious global issues related to the development of energy, such as environmental contamination, and the intermittence of the traditional energy sources. Creating new battery-related energy storage facilities is an urgent subject for human beings to address and for solutions for the future. Compared with lithium-based batteries, sodium-ion batteries have become the new focal point in the competition for clean energy solutions and have more potential for commercialization due to the huge natural abundance of sodium. Nevertheless, sodium-ion batteries still exhibit some challenges, like inferior electrochemical performance caused by the bigger ionic size of Na
Early puberty, ‘sexualization’ and feminism
Publisher: SAGE Publications
Date: 15-04-2013
Abstract: Early onset puberty is increasingly prevalent among girls globally according to many scientists and clinicians. In the medical and scientific literature early sexual development is described as a problem for girls and as a frightening prospect for parents. News media and popular environmentalist accounts lify these figurations, raising powerful concerns about the sexual predation of early developing girls by men and boys and the loss of childhood innocence. In this article the author frames one feminist approach to early puberty, arguing that feminist theorists should both take scientific work around population changes in sexual development seriously and use their critical skills to unpick and challenge the discourses constituting early development as a matter of concern. The author suggests that contemporary academic and policy debates on the ‘sexualization’ of girls have important resonance for critical explorations of early puberty. These debates currently pay little attention to the physiological aspects of sexual development and could be enriched by so doing. As in the case of ‘sexualization’, issues of class, racialization and agency are central to understanding and challenging normative concerns about girls’ early sexual development.
`A matter of embodied fact'

Date: 04-2002
DOI: 10.1177/1460012002003001063
Abstract: Sex hormones today are seen as central to the production of biological sexual difference. This article examines the development of this scientific `fact', and asks how hormones came to be in this position. The article does not involve original historical research, however. Instead it uses existing histories of hormonal sexual difference to develop a theoretical argument about body histories. How can the history of scientific views of bodies be written and understood? What can these histories tell us about the relation between scientific representations of bodies and the materiality of bodies? Combining and critiquing arguments from feminist histories of science, Bruno Latour's actor network theory, Michel Serres's theory of folded time, and Donna Haraway's notion of situated knowledges, this article argues for the centrality of embodiment and location to useful body histories.

Calling for Care: ‘Disembodied’ Work, Teleoperators and Older People Living at Home
Publisher: SAGE Publications
Date: 02-02-2012
Abstract: The provision of ‘distant’ care to older people living at home through telecare technologies is often contrasted negatively to hands-on, face-to-face care: telecare is seen as a loss of care, a dehumanization. Here we challenge this view, arguing that teleoperators in telecare services do provide care to older people, often at significant emotional cost to themselves. Based on a European Commission-funded ethnographic study of two English telecare monitoring centres, we argue that telecare is not ‘disembodied’ work, but a form of care performed through the use of voice, knowledge sharing and emotional labour or self-management. We also show, in distinction to discourses promoting telecare in the UK, that successful telecare relies on the existence of social networks and the availability of hands-on care. Telecare is not a substitute for, or the opposite of, hands-on care but is at its best interwoven with it.
Characteristics associated with poor COVID-19 outcomes in individuals with systemic lupus erythematosus: data from the COVID-19 Global Rheumatology Alliance

DOI: 10.1136/ANNRHEUMDIS-2021-221636
Abstract: To determine characteristics associated with more severe outcomes in a global registry of people with systemic lupus erythematosus (SLE) and COVID-19. People with SLE and COVID-19 reported in the COVID-19 Global Rheumatology Alliance registry from March 2020 to June 2021 were included. The ordinal outcome was defined as: (1) not hospitalised, (2) hospitalised with no oxygenation, (3) hospitalised with any ventilation or oxygenation and (4) death. A multivariable ordinal logistic regression model was constructed to assess the relationship between COVID-19 severity and demographic characteristics, comorbidities, medications and disease activity. A total of 1606 people with SLE were included. In the multivariable model, older age (OR 1.03, 95% CI 1.02 to 1.04), male sex (1.50, 1.01 to 2.23), prednisone dose (1–5 mg/day 1.86, 1.20 to 2.66, 6–9 mg/day 2.47, 1.24 to 4.86 and ≥10 mg/day 1.95, 1.27 to 2.99), no current treatment (1.80, 1.17 to 2.75), comorbidities (eg, kidney disease 3.51, 2.42 to 5.09, cardiovascular disease/hypertension 1.69, 1.25 to 2.29) and moderate or high SLE disease activity (vs remission 1.61, 1.02 to 2.54 and 3.94, 2.11 to 7.34, respectively) were associated with more severe outcomes. In age-adjusted and sex-adjusted models, mycophenolate, rituximab and cyclophosphamide were associated with worse outcomes compared with hydroxychloroquine outcomes were more favourable with methotrexate and belimumab. More severe COVID-19 outcomes in in iduals with SLE are largely driven by demographic factors, comorbidities and untreated or active SLE. Patients using glucocorticoids also experienced more severe outcomes.

Adopting Neuroscience
Publisher: SAGE Publications
Date: 31-07-2017
Abstract: What happens when neuroscientific knowledges move from laboratories and clinics into therapeutic settings concerned with the care of children? ‘Brain-based parenting’ is a set of discourses and practices emerging at the confluence of attachment theory, neuroscience, psychotherapy and social work. The neuroscientific knowledges involved understand affective states such as fear, anger and intimacy as dynamic patterns of coordination between brain localities, as well as flows of biochemical signals via hormones such as cortisol. Drawing on our own attempts to adopt brain-based parenting, and engaging with various strands and critiques of new materialism and affect theory, we explore the ways in which the social sciences and humanities might fruitfully engage with neuroscientific concepts and affects. How does science-affected indeterminacy, with all its promises of ontological and experiential agency, help us to observe, wait, bind or hold together volatile mixtures of habit, speech and action?

Telecare and older people: Who cares where?

DOI: 10.1016/J.SOCSCIMED.2010.08.014
Abstract: 'Telecare solutions' are seen as a potential means of addressing the future care needs of ageing societies in Western economies. The development of these remote care systems runs in parallel with policies aimed at 'ageing in place' and is targeted at supporting the perceived care needs of frail older people within the home. Drawing on ethnographic and deliberative panel data from European Community funded research, we consider how these developments contribute to a reshaping of the place and experience of care for older people. We do so by addressing the ways in which remote care systems can, firstly, act to change the experience of home and secondly, re-order the place of care-work and responsibilities to care as new actors become enrolled within the care network and existing care-givers take on differing roles and responsibilities. Finally, we consider how this paper contributes to conceptual debates around institution and extitution - that is, the de-territorialisation of the physical structure of the institution and its re-manifestation through new spaces and times that seek to end interior and exterior distinctions.

Drowning in a Sea of Estrogens: Sex Hormones, Sexual Reproduction and Sex
Publisher: SAGE Publications
Date: 05-2003
DOI: 10.1177/1363460703006002003
Abstract: Contemporary life is taking its toll on sex, according to scientific, environmental and pop-scientific literature. Both women and men are being overwhelmed with estrogens and hormonally active chemicals in their environments - in water, plastics, and food. Such `estrogenization' produces interesting questions about the `nature' of sex, gender and reproduction, and their relations to each other. This paper critically juxtaposes contemporary discourses on estrogenization with feminist work on sex, gender and reproduction. It asks: How might a feminist theorizing of the body take on questions about sex hormones without essentializing sex or reproduction, or underestimating their relevance as biological actors in the production of sex?

Paid to share: IVF patients, eggs and stem cell research

Abstract: Following a recent decision by the human fertilisation and embryology authority (HFEA), British women undergoing in vitro fertilisation (IVF) treatment can be 'paid to share' their eggs with stem cell researchers. The HFEA and the clinic proposing the scheme present this as a 'win-win' arrangement benefiting both infertile women and couples and British science. It is also represented as concurrently both 'business as usual' and an exceptional case. Constituting a significant departure from the previous policy and practice of altruistic donation, the scheme has raised significant concerns among clinicians and activists. Here, we ask what questions feminists can bring to these debates without resorting to a position of either refusal or affirmation. Drawing on erse materials from public debates, as well as social scientific literature on gamete and embryo donation, we undertake a close analysis of the discursive framing and justification of the proposal. We argue that these discourses are characterised by three linked areas of elision and distinction: treatment and research eggs and embryos and donation and selling. Our analysis highlights the need for innovative social, ethical and political consideration of egg sharing for stem cell research.

Abstract: Some patients with rheumatic diseases might be at higher risk for coronavirus disease 2019 (COVID‐19) acute respiratory distress syndrome (ARDS).

Data were derived from the COVID‐19 Global Rheumatology Alliance Registry from March 24, 2020, to May 12, 2021. Seven machine learning classifiers were trained on ARDS outcomes using 83 variables obtained at COVID‐19 diagnosis. Predictive performance was assessed in a US test set and was validated in patients from four countries with independent registries using area under the curve (AUC), accuracy, sensitivity, and specificity. A simple risk score calculator was developed using a regression model incorporating the most influential predictors from the best performing classifier. The study included 8633 patients from 74 countries, of whom 523 (6%) had ARDS. Gradient boosting had the highest mean AUC (0.78 95% confidence interval [CI]: 0.67‐0.88) and was considered the top performing classifier. Ten predictors were identified as key risk factors and were included in a regression model. The regression model that predicted ARDS with 71% (95% CI: 61%‐83%) sensitivity in the test set, and with sensitivities ranging from 61% to 80% in countries with independent registries, was used to develop the risk score calculator. We were able to predict ARDS with good sensitivity using information readily available at COVID‐19 diagnosis. The proposed risk score calculator has the potential to guide risk stratification for treatments, such as monoclonal antibodies, that have potential to reduce COVID‐19 disease progression.

COVID-19 in Pregnant Women With Rheumatic Disease: Data From the COVID-19 Global Rheumatology Alliance
Publisher: The Journal of Rheumatology
Date: 09-2021
Abstract: To describe coronavirus disease 2019 (COVID-19) and pregnancy outcomes in patients with rheumatic disease who were pregnant at the time of infection. Since March 2020, the COVID-19 Global Rheumatology Alliance has collected cases of patients with rheumatic disease with COVID-19. We report details of pregnant women at the time of COVID-19 infection, including obstetric details separately ascertained from providers. We report on 39 patients, including 22 with obstetric detail available. The mean and median age was 33 years, range 24–45 years. Rheumatic disease diagnoses included rheumatoid arthritis (n = 9), systemic lupus erythematosus (n = 9), psoriatic arthritis/other inflammatory arthritides (n = 8), and antiphospholipid syndrome (n = 6). Most had a term birth (16/22), with 3 preterm births, 1 termination, and 1 miscarriage 1 woman had yet to deliver at the time of report. One-quarter (n = 10/39) of pregnant women were hospitalized following COVID-19 diagnosis. Two of 39 (5%) required supplemental oxygen (both hospitalized) no patients died. The majority did not receive specific medication treatment for their COVID-19 (n = 32/39, 82%), and 7 patients received some combination of antimalarials, colchicine, anti–interleukin 1β, azithromycin, glucocorticoids, and lopinavir/ritonavir. Women with rheumatic diseases who were pregnant at the time of COVID-19 had favorable outcomes. These data have limitations due to the small size and methodology however, they provide cautious optimism for pregnancy outcomes for women with rheumatic disease particularly in comparison to the increased risk of poor outcomes that have been reported in other series of pregnant women with COVID-19.
Ageing with telecare: care or coercion in austerity?
Publisher: Wiley
Date: 25-10-2012
DOI: 10.1111/J.1467-9566.2012.01530.X
Abstract: In recent years images of independence, active ageing and staying at home have come to characterise a successful old age in western societies. 'Telecare' technologies are heavily promoted to assist ageing-in-place and a nexus of demographic ageing, shrinking healthcare and social care budgets and technological ambition has come to promote the 'telehome' as the solution to the problem of the 'age dependency ratio'. Through the adoption of a range of monitoring and telecare devices, it seems that the normative vision of independence will also be achieved. But with falling incomes and pressure for economies of scale, what kind of independence is experienced in the telehome? In this article we engage with the concepts of 'technogenarians' and 'shared work' to illuminate our analysis of telecare in use. Drawing on European-funded research we argue that home-monitoring based telecare has the potential to coerce older people unless we are able to recognise and respect a range of responses including non-use and 'misuse' in daily practice. We propose that re-imagining the aims of telecare and redesigning systems to allow for creative engagement with technologies and the co-production of care relations would help to avoid the application of coercive forms of care technology in times of austerity.
An evidence-based specialist breast nurse role in practice: a multicentre implementation study

DOI: 10.1046/J.1365-2354.2003.00331.X
Abstract: The objective of this study was to examine the feasibility, implementation, acceptability and impact of an evidence-based specialist breast care nurse (SBN) model of care in Australia. Primary data were collected from four erse Australian breast cancer treatment centres over a 12-month period. The design was a multicentre demonstration project. Information about the provision of care and patient needs was collected through prospective logs. Structured interviews were conducted with women who received the SBN intervention (N = 167) and with a control group of women treated prior to the intervention period (N = 133). Health professionals (N = 47) were interviewed about their experience of the SBN. Almost all women had contact with an SBN at five scheduled consultations and 67% of women in the intervention group requested at least one additional consultation with the SBN. Women in the intervention group were more likely to receive hospital fact sheets and to be told about and participate in clinical trials. Ninety-eight per cent of women reported that the availability of an SBN would affect their choice of hospital, with 48% indicating that they would recommend only a hospital with a SBN available. Health professionals reported that SBNs improved continuity of care, information and support for the women, and resulted in more appropriate referrals and use of the time of other members of the team. In conclusion, the SBN model is feasible and acceptable within erse Australian treatment centres there is evidence that some aspects of care were improved by the SBN.

Tunable Carbon Surface from Mono- to Multi-Metallic Single Atoms
Publisher: American Chemical Society (ACS)
Date: 08-05-2020
DOI: 10.26434/CHEMRXIV.12264083.V1
Abstract: Herein, we develop a non-selective charge compensation strategy to prepare multi-single-atom doped carbon (MSAC) in which a sodium p-toluenesulfonate (PTS-Na) doped polypyrrole (S-PPy) polymer is designed to anchor discretionary mixtures of multiple metal cations, including iron (Fe 3+ ), cobalt (Co 3+ ), ruthenium (Ru 3+ ), palladium (Pd 2+ ), indium (In 3+ ), iridium (Ir 2+ ), and platinum (Pt 2+ ) . As illustrated in Figure 1, the carbon surface can be tuned with different level of compositional complexities, including unary Pt 1 @NC, binary (MSAC-2, (PtFe) 1 @NC), ternary (MSAC-3, (PtFeIr) 1 @NC), quaternary (MSAC-4, (PtFeIrRu) 1 @NC), quinary (MSAC-5, (PtFeIrRuCo) 1 @NC), senary (MSAC-6, (PtFeIrRuCoPd) 1 @NC), and septenary (MSAC-7, (PtFeIrRuCoPdIn) 1 @NC) s les. The structural evolution of carbon surface dictates the activities of both ORR and HER. The senary MSAC-6 achieves the ORR mass activity of 18.1 A·mg metal -1 at 0.9 V (Vs reversible hydrogen electrode (RHE)) over 30K cycles, which is 164 times higher than that of commercial Pt/C. The quaternary MSAC-4 presented a comparable HER catalytic capability with that of Pt/C. These results indicate that the highly complexed carbon surface can enhance its ability over general electrochemical catalytic reactions. The mechanisms regarding of the ORR and HER activities of the alternated carbon surface are also theoretically and experimentally investigated in this work, showing that the synergistic effects amongst the co-doped atoms can activate or inactivate certain single-atom sites.

A Review on the Status and Challenges of Cathodes in Room‐Temperature Na‐S Batteries
Publisher: Wiley
Date: 27-12-2022
Abstract: The cathode materials for sodium‐sulfur batteries have attracted great attention since cathode is one of the important components of the sodium‐sulfur battery, and there are cathode materials that have high capacity, non‐toxicity, and cost‐efficiency. Nevertheless, due to their low Coulombic efficiency and proneness to cycling decay, the practical application of the sodium–sulfur battery has always been suppressed. In terms of the responsibility of these problems, the polysulfide shuttle and the sluggish kinetics are the main culprits. To address these issues, impeding the notorious reaction between polysulfide intermediates on the cathode and improve the kinetics reaction on the anode are extremely important. Herein, a comprehensive review is prepared of different approaches to increasing the electrochemical performance and strengthening the stability of cathodes. The influences of various choices and the consequent properties of the cathode in relation to the whole sodium–sulfur battery performance is investigated. Finally, the current research challenges related to cathodes for sodium–sulfur batteries and future perspectives are also discussed.
Association Between Race/Ethnicity and COVID-19 Outcomes in Systemic Lupus Erythematosus Patients From the United States: Data From the COVID-19 Global Rheumatology Alliance.
Publisher: Wiley
Date: 02-12-2022
DOI: 10.1002/ACR.25039
Abstract: To determine the association between race/ethnicity and COVID-19 outcomes in in iduals with systemic lupus erythematosus (SLE). In iduals with SLE from the US with data entered into the COVID-19 Global Rheumatology Alliance registry between March 24, 2020 and August 27, 2021 were included. Variables included age, sex, race, and ethnicity (White, Black, Hispanic, other), comorbidities, disease activity, pandemic time period, glucocorticoid dose, antimalarials, and immunosuppressive drug use. The ordinal outcome categories were: not hospitalized, hospitalized with no oxygenation, hospitalized with any ventilation or oxygenation, and death. We constructed ordinal logistic regression models evaluating the relationship between race/ethnicity and COVID-19 severity, adjusting for possible confounders. We included 523 patients 473 (90.4%) were female and the mean ± SD age was 46.6 ± 14.0 years. A total of 358 patients (74.6%) were not hospitalized 40 patients (8.3%) were hospitalized without oxygen, 64 patients (13.3%) were hospitalized with any oxygenation, and 18 (3.8%) died. In a multivariable model, Black (odds ratio [OR] 2.73 [95% confidence interval (95% CI) 1.36-5.53]) and Hispanic (OR 2.76 [95% CI 1.34-5.69]) in iduals had higher odds of more severe outcomes than White in iduals. Black and Hispanic in iduals with SLE experienced more severe COVID-19 outcomes, which is consistent with findings in the US general population. These results likely reflect socioeconomic and health disparities and suggest that more aggressive efforts are needed to prevent and treat infection in this population.

Processing Rusty Metals into Versatile Prussian Blue for Sustainable Energy Storage
Publisher: Wiley
Date: 13-10-2021
Abstract: To reach a closed‐loop material system and meet the urgent requirement of sustainable energy storage technologies, it is essential to incorporate efficient waste management into designing new energy storage materials. Here, a “two birds with one stone” strategy to transform rusty iron products into Prussian blue as high‐performance cathode materials, and recover the rusty iron products to their original status, is reported. Owing to the high crystalline and Na + content, the rusty iron derived Prussian blue shows a high specific capacity of 145 mAh g −1 and excellent cycling stability over 3500 cycles. Through the in situ X‐ray diffraction and in situ Raman spectra, it is found that the impressive ion storage capability and stability are strongly related to the suppressed structure distortion during the charge/discharge process. The ion migration mechanism and the possibility to serve as a universal host for other kinds of ions are further illuminated by density functional theory calculations. This work provides a new strategy for recycling wasted materials into high value‐added materials for sustainable battery systems, and is adaptable in the nanomedicine, catalysis, sensors, and gas storage applications.
Associations of baseline use of biologic or targeted synthetic DMARDs with COVID-19 severity in rheumatoid arthritis: Results from the COVID-19 Global Rheumatology Alliance physician registry
Publisher: BMJ
Date: 28-05-2021
DOI: 10.1136/ANNRHEUMDIS-2021-220418
Abstract: To investigate baseline use of biologic or targeted synthetic (b/ts) disease-modifying antirheumatic drugs (DMARDs) and COVID-19 outcomes in rheumatoid arthritis (RA). We analysed the COVID-19 Global Rheumatology Alliance physician registry (from 24 March 2020 to 12 April 2021). We investigated b/tsDMARD use for RA at the clinical onset of COVID-19 (baseline): abatacept (ABA), rituximab (RTX), Janus kinase inhibitors (JAKi), interleukin 6 inhibitors (IL-6i) or tumour necrosis factor inhibitors (TNFi, reference group). The ordinal COVID-19 severity outcome was (1) no hospitalisation, (2) hospitalisation without oxygen, (3) hospitalisation with oxygen/ventilation or (4) death. We used ordinal logistic regression to estimate the OR (odds of being one level higher on the ordinal outcome) for each drug class compared with TNFi, adjusting for potential baseline confounders. Of 2869 people with RA (mean age 56.7 years, 80.8% female) on b/tsDMARD at the onset of COVID-19, there were 237 on ABA, 364 on RTX, 317 on IL-6i, 563 on JAKi and 1388 on TNFi. Overall, 613 (21%) were hospitalised and 157 (5.5%) died. RTX (OR 4.15, 95% CI 3.16 to 5.44) and JAKi (OR 2.06, 95% CI 1.60 to 2.65) were each associated with worse COVID-19 severity compared with TNFi. There were no associations between ABA or IL6i and COVID-19 severity. People with RA treated with RTX or JAKi had worse COVID-19 severity than those on TNFi. The strong association of RTX and JAKi use with poor COVID-19 outcomes highlights prioritisation of risk mitigation strategies for these people.
Characteristics and Outcomes of People With Gout Hospitalized Due to COVID ‐19: Data From the COVID ‐19 Global Rheumatology Alliance Physician‐Reported Registry
Publisher: Wiley
Date: 24-08-2022
DOI: 10.1002/ACR2.11495
Abstract: To describe people with gout who were diagnosed with coronavirus disease 2019 (COVID‐19) and hospitalized and to characterize their outcomes. Data on patients with gout hospitalized for COVID‐19 between March 12, 2020, and October 25, 2021, were extracted from the COVID‐19 Global Rheumatology Alliance registry. Descriptive statistics were used to describe the demographics, comorbidities, medication exposures, and COVID‐19 outcomes including oxygenation or ventilation support and death. One hundred sixty‐three patients with gout who developed COVID‐19 and were hospitalized were included. The mean age was 63 years, and 85% were male. The majority of the group lived in the Western Pacific Region (35%) and North America (18%). Nearly half (46%) had two or more comorbidities, with hypertension (56%), cardiovascular disease (28%), diabetes mellitus (26%), chronic kidney disease (25%), and obesity (23%) being the most common. Glucocorticoids and colchicine were used pre‐COVID‐19 in 11% and 12% of the cohort, respectively. Over two thirds (68%) of the cohort required supplemental oxygen or ventilatory support during hospitalization. COVID‐19‐related death was reported in 16% of the overall cohort, with 73% of deaths documented in people with two or more comorbidities. This cohort of people with gout and COVID‐19 who were hospitalized had high frequencies of ventilatory support and death. This suggests that patients with gout who were hospitalized for COVID‐19 may be at risk of poor outcomes, perhaps related to known risk factors for poor outcomes, such as age and presence of comorbidity.

Experiencing new forms of genetic choice: Findings from an ethnographic study of preimplantation genetic diagnosis
Publisher: Informa UK Limited
Date: 2004
DOI: 10.1080/14647270400016449
Abstract: Contemporary scientific and clinical knowledges and practices continue to make available new forms of genetic information, and to create new forms of reproductive choice. For ex le, couples at high risk of passing on a serious genetic condition to their offspring in Britain today have the opportunity to use Preimplantation Genetic Diagnosis (PGD) to select embryos that are unaffected by serious genetic disease. This information assists these couples in making reproductive choices. This article presents an analysis of patients' experiences of making the decision to undertake PGD treatment and of making reproductive choices based on genetic information. We present qualitative interview data from an ethnographic study of PGD based in two British clinics which indicate how these new forms of genetic choice are experienced by patients. Our data suggest that PGD patients make decisions about treatment in a complex way, taking multiple variables into account, and maintaining ongoing assessments of the multiple costs of engaging with PGD. Patients are aware of broader implications of their decisions, at personal, familial, and societal levels, as well as clinical ones. Based on these findings we argue that the ethical and social aspects of PGD are often as innovative as the scientific and medical aspects of this technique, and that in this sense, science cannot be described as "racing ahead" of society.

Hard Carbon Anodes: Fundamental Understanding and Commercial Perspectives for Na‐Ion Batteries beyond Li‐Ion and K‐Ion Counterparts
Publisher: Wiley
Date: 30-11-2020
Abstract: Hard carbon (HC) is recognized as a promising anode material with outstanding electrochemical performance for alkali metal‐ion batteries including lithium‐ion batteries (LIBs), as well as their analogs sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs). Herein, a comprehensive review of the recent research is presented to interpret the challenges and opportunities for the applications of HC anodes. The ion storage mechanisms, materials design, and electrolyte optimizations for alkali metal‐ion batteries are illustrated in‐depth. HC is particularly promising as an anode material for SIBs. The solid‐electrolyte interphase, initial Coulombic efficiency, safety concerns, and all‐climate performances, which are vital for practical applications, are comprehensively discussed. Furthermore, commercial prototypes of SIBs based on HC anodes are extensively elaborated. The remaining challenges and research perspectives are provided, aiming to shed light on future research and early commercialization of HC‐based SIBs.

Atomic Cobalt Vacancy‐Cluster Enabling Optimized Electronic Structure for Efficient Water Splitting
Publisher: Wiley
Date: 20-04-2021
Abstract: Vacancies created on a surface can alter the local electronic structure, thus enabling a higher intrinsic activity for the evolution of hydrogen and oxygen. Conventional strategies for vacancy engineering, however, have a strong focus on non‐metal sulfur/oxygen defects, which have often overlooked metallic vacancies. Herein, evidence is provided that cobalt vacancies can be atomically tuned to have different sizes to achieve cobalt vacancy clusters through controlling the migration of iridium single atoms. The coalescence of Co vacancy clusters at the surface of an IrCo alloy results in an increased d‐band level and eventually compromises H adsorption, leading to enhanced electrocatalytic activity toward the hydrogen evolution reaction. In addition, the Co vacancy clusters can improve the electronic conductivity with respect to the oxidized Co surface, which substantially aids in strengthening the adsorption of oxygen intermediates toward an effective oxygen evolution reaction at a low overpotential. These collective effects originate from the Co vacancy cluster and specifically enable highly efficient and stable water splitting with a low total overpotential of 384 mV in alkaline media and 365 mV in an acidic environment, achieving a current density of 10 mA cm –2 .

General π‐Electron‐Assisted Strategy for Ir, Pt, Ru, Pd, Fe, Ni Single‐Atom Electrocatalysts with Bifunctional Active Sites for Highly Efficient Water Splitting
Publisher: Wiley
Date: 10-07-2019
Abstract: Both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) are crucial to water splitting, but require alternative active sites. Now, a general π‐electron‐assisted strategy to anchor single‐atom sites (M=Ir, Pt, Ru, Pd, Fe, Ni) on a heterogeneous support is reported. The M atoms can simultaneously anchor on two distinct domains of the hybrid support, four‐fold N/C atoms (M@NC), and centers of Co octahedra (M@Co), which are expected to serve as bifunctional electrocatalysts towards the HER and the OER. The Ir catalyst exhibits the best water‐splitting performance, showing a low applied potential of 1.603 V to achieve 10 mA cm −2 in 1.0 m KOH solution with cycling over 5 h. DFT calculations indicate that the Ir@Co (Ir) sites can accelerate the OER, while the Ir@NC 3 sites are responsible for the enhanced HER, clarifying the unprecedented performance of this bifunctional catalyst towards full water splitting.
