A new concept for manufacturing wrinkling patterns on hard-nano-film/soft-matter-substrate

Researchers proposed a new method to control wrinkling and buckling of thin stiff film on soft substrate. They found that the curve pattern on the soft substrate has obvious influence on the wrinkling distribution of the thin film/soft substrate.

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.
