In 1896, German chemist Emil Fischer noted something very strange about a molecule named acetaldehyde phenylhydrazone. Identical batches of the crystalline compound appeared to have wildly different ...

Scientists propose a groundbreaking theory for predicting melting points. The theory offers a universal description of melting lines across various material types. This discovery has significant ...

For the first time, researchers have measured atomic temperatures in extreme matter and found gold surviving at 19,000 kelvins, more than 14 times its melting point. The result dismantles a ...
