Porous silica protects nickel catalyst

By wrapping nickel nanoparticles in a protective shield of porous silica, A*STAR researchers have developed a highly active and robust catalyst that could help to produce methane from biomass.

Dragonfly-inspired nano coating kills bacteria upon contact

Studies have shown that the wings of dragonflies and cicadas prevent bacterial growth due to their natural structure. The surfaces of their wings are covered in nanopillars making them look like a bed of nails. When bacteria ...
