Recent advances in vacuum ultraviolet photochemistry of astrochemically important small molecules
The photodissociation of an isolated molecule from a well-defined initial quantum state provides a lens through which one can investigate how and why chemical reactions occur, and provides numerous opportunities for fruitful, synergistic collaboratio.....»»
Scientists enrich nitric oxide-reducing microbes in bioreactor
Nitric oxide (NO) is a fascinating and versatile molecule, important for all living things as well as the environment. It is highly reactive and toxic, organisms use it as a signaling molecule, it depletes the ozone layer in our planet's atmosphere,.....»»
Scientists synthesize isotopic atropisomers based on carbon isotope discrimination
In chemistry, a molecule or ion is said to be chiral if it cannot be superposed on to its mirror image by any combination of rotations, translations, or conformational changes. A chiral molecule or ion exists in two forms, called enantiomers, that ar.....»»
Scientists develop strategy to engineer artificial allosteric sites in protein complexes
According to a recently published research paper, an approach has been developed to create artificial allosteric sites (where by binding an effector molecule, activity at the distal active site is regulated) in protein complexes. This breakthrough re.....»»
