Successful synthesis of rare isotopic atropisomers with high rotational stability
Stereochemistry, or the study of spatial arrangements of the atoms in a molecule, is a highly explored subdiscipline of organic chemistry. It has led to the synthesis of numerous chiral compounds—compounds with non-superimposable mirror images or e.....»»
From branches to loops: The physics of transport networks in nature
An international team of researchers described how loops, crucial for the stability of such networks, occur in transport networks found in nature. The researchers observed that when one branch of the network reaches the system's boundary, the interac.....»»
NASA confirms space station cracking a “highest” risk and consequence problem
