Improved artificial spider silk created

Researchers have made improved artificial spider silk, and it is ‘spun’ from a material that is 98% water. The fibers, which resemble miniature bungee cords as they can absorb large amounts of energy, are sustainable, non-toxic and can be made …

Invisibility cloaks boosts solar energy conversion efficiency

Researchers demonstrated a performance improvement of state-of-the-art silicon solar cells by cloaking their metal contact fingers. The cloaking free-form surfaces are fabricated on silicon heterojunction solar cells using direct laser writing of polymers and subsequent soft imprinting. Cloaking performance is …
