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 ...
The latest short science news items from C&EN. Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen ...
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, ...
Protein low-complexity domains (LCDs) stack together to form dynamic liquid droplets within the cell; alas, some pathogenic mutations in these regions encourage aggregation beyond this temporary ...
MIT researchers have developed a lightweight polymer film that is nearly impenetrable to gas molecules, raising the possibility that it could be used as a protective coating to prevent solar cells and ...
DAYTON, OHIO (WDTN) – You have heard over the last week that salt is not effective at melting snow below 15 degrees, but ...
Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...
