When heated with a burst of laser light, hydrogen bonds between water molecules shorten briefly. The work sheds new light on the structure of water. (Greg Stewart/SLAC) Water is the most abundant yet ...
Some polymers react to their environment with conformational changes: one of these is the polymer PNIPAM, short for poly(N-isopropylacrylamide). It is water-soluble below around 32 degrees Celsius, ...
