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.

Unavoidable disorder used to build nanolaser

Scientists have discovered that imperfect nanostructures can offer entirely new functionalities. They have shown that imperfect optical chips can be used to produce 'nanolasers', which is an ultimately compact and energy-efficient light source.
