Demagnetization dynamics on a femtosecond time scale

New experimental results, obtained from a novel ultra-fast probe technique, have challenged some long-held assumptions about magnetic behavior in alloys; and anticipated improvements in short-wavelength probe output will leave the team poised to provide unprecedented insights into condensed-matter metrology at ever smaller dimensions.

World's first light-activated antimicrobial surface that also works in the dark

Scientists have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light - even under modest indoor lighting. And in a first for this type of substance, it also shows impressive antibacterial properties in total darkness.

Mother-of-pearl inspires super-strong material

This material, almost ten times stronger than a conventional ceramic, is the result of an innovative manufacturing process that includes a freezing step. This method appears to be compatible with large-scale industrialization and should not be much more expensive than the techniques already in use.
