Materials scientists aim to use bioinspired soft robots to carry out advanced interactions between humans and robots, but the associated technology remains to be developed. For example, soft actuators must perform quickly ...
A molecule of ammonia, NH3, typically exists as an umbrella shape, with three hydrogen atoms fanned out in a nonplanar arrangement around a central nitrogen atom. This umbrella structure is very stable and would normally ...
