Mutual affinity of electron polarons and water at a TiO2 surface
Titania has been the subject of a tremendous amount of research, most of it related to its photocatalytic applications. Central to these studies has been the work that has explored the interaction of water with TiO2 surfaces. Indeed, this is now quite well understood....
Correlation between melanin levels and free radical formation in human cells following illumination by ultraviolet A light.
Melanin is a naturally-occurring pigment that is largely responsible for skin colour. It absorbs the ultraviolet and blue components of sunlight, thus preventing the photochemical formation of free radicals that can damage DNA in the skin. In darkly pigmented skin,...
Creating new antibiotics from our own immune system
New antibiotics are desperately needed: without them antimicrobial resistance is predicted to kill more people than cancer. An international collaboration between scientists at the London Centre for Nanotechnology (LCN), University of Oxford, IBM, STFC Daresbury...
