New adhesive binds tight in cold, gets stronger in heat
CLEVELAND, US: Case Western Reserve University, Dayton Air Force Research Laboratory and China scientists have developed a new dry adhesive that bonds in extreme temperatures—a quality that could make the product ideal for space exploration and beyond. The gecko-inspired adhesive loses no traction in temperatures as cold as liquid nitrogen or as hot as molten silver, and actually gets stickier as heat increases, the researchers reported. Read More
