Engineering biomimetic lubrication with mucin. Engineering coatings for water to be an effective lubricant is a significant challenge. The project seeks to emulate how nature builds highly lubricating water-rich polymer films on biological surfaces. This is intended to be achieved by directing the self-assembly of mucin macromolecules onto polymer brushes attached to a substrate, and then cross-linking the constituents to obtain a hydrated gel-like lubricating coating. This research is expected ....Engineering biomimetic lubrication with mucin. Engineering coatings for water to be an effective lubricant is a significant challenge. The project seeks to emulate how nature builds highly lubricating water-rich polymer films on biological surfaces. This is intended to be achieved by directing the self-assembly of mucin macromolecules onto polymer brushes attached to a substrate, and then cross-linking the constituents to obtain a hydrated gel-like lubricating coating. This research is expected to provide new insights on the mechanisms by which mucin-rich fluids lubricate and protect biosurfaces, which is important to human health, nutrition and well-being. It may also lead to new discoveries for engineering surface coatings for biomaterials and nanomaterials.Read moreRead less
Enabling the design of superior healthy snack foods and beverages through innovative assessment of oral processing and mucosal film interactions. Reducing sugar and fat in foods generally leads to products that are perceived as less flavoursome and appealing. A significant contributor to this is the interaction of foods and beverages with oral mucosal substrates, which play a key role in perceptual processes that drive unacceptable mouthfeel sensations. This project seeks to develop and use oral ....Enabling the design of superior healthy snack foods and beverages through innovative assessment of oral processing and mucosal film interactions. Reducing sugar and fat in foods generally leads to products that are perceived as less flavoursome and appealing. A significant contributor to this is the interaction of foods and beverages with oral mucosal substrates, which play a key role in perceptual processes that drive unacceptable mouthfeel sensations. This project seeks to develop and use oral mimetic substrates to permit objective and quantified rheological and tribological responses, imitating the underlying physics occurring during food oral processing that drive dynamic sensory responses. The project aims to enable a mechanism-based approach to minimise the amounts of fat, salt and sugar required for sensory properties that meet consumer expectations.Read moreRead less
Multiscale viscoelastic lubrication of soft matter systems. The project aims to develop new principles of viscoelastic lubrication in soft contacts. New insights into friction behaviour arising from complex fluid-substrate interactions are expected to be generated using techniques and interdisciplinary approaches that bridge rheology, tribology and surface science. The intended outcome is a lubrication model that interprets the contribution of viscoelastic effects occurring across multiple lengt ....Multiscale viscoelastic lubrication of soft matter systems. The project aims to develop new principles of viscoelastic lubrication in soft contacts. New insights into friction behaviour arising from complex fluid-substrate interactions are expected to be generated using techniques and interdisciplinary approaches that bridge rheology, tribology and surface science. The intended outcome is a lubrication model that interprets the contribution of viscoelastic effects occurring across multiple length and time scales. This should provide significant benefits to diverse fields including advanced materials and complex fluids, engineering tribology, bio-lubrication and food structure design.Read moreRead less
