The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

In situ measurements of the electrostatic properties inside photosynthetic reaction centres: correlation with the energy conversion function of the protein. The photochemical reaction centre is a key protein complex involved in energy conversion. It converts solar energy into chemical energy as a transmembrane charge separation. Coupling of electron and proton transfer is catalysed at the level of a ubiquinone cofactor. In order to understand how the redox properties of this cofactor are fine tu ....In situ measurements of the electrostatic properties inside photosynthetic reaction centres: correlation with the energy conversion function of the protein. The photochemical reaction centre is a key protein complex involved in energy conversion. It converts solar energy into chemical energy as a transmembrane charge separation. Coupling of electron and proton transfer is catalysed at the level of a ubiquinone cofactor. In order to understand how the redox properties of this cofactor are fine tuned by the protein environment, we plan to probe the ubiquinone site using a voltage-sensitive fluorescent dye. This exciting multidisciplinary project will contribute to the understanding of how protein matrices influence and govern the midpoint redox potential of their cofactors and the environments of theirRead moreRead less
Raman spectroscopy and imaging of natural and synthetic melanins. The national benefit of this research lies in three main areas. First, this research could lead to a non-invasive diagnostic for melanoma. Second, it could reveal stronger connections between melanin and melanoma development than previously believed and thus inspire possible methods of treatment or prevention of melanoma. Given Australia's high incidence of melanoma, these could have an enormous impact on our health care system. T ....Raman spectroscopy and imaging of natural and synthetic melanins. The national benefit of this research lies in three main areas. First, this research could lead to a non-invasive diagnostic for melanoma. Second, it could reveal stronger connections between melanin and melanoma development than previously believed and thus inspire possible methods of treatment or prevention of melanoma. Given Australia's high incidence of melanoma, these could have an enormous impact on our health care system. Third, it will increase our understanding of the melanin pigment and further establish Australia as a leader in this field. Given the links between melanin and Parkinson's Disease and immune response, this understanding could have greater impact on health care than simply melanoma.Read moreRead less
