New hyperbolic metamaterial fabricated by researchers at King’s College London.
A new type of hyperbolic metamaterial has been developed by researchers at King’s College London (KCL) allowing researchers have greater flexibility of manipulating light-matter interactions at the nanoscale. Hyperbolic Metamaterials are artificial...
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,...
