Single crystals of 5,5′-diethylbarbituric acid (barbital) were irradiated with 4.0-MeV electrons and studied by ESR in the temperature range 77 to 300 K. Altogether, five radicals have been identified ...
Deferoxamine mesylate, bovine SOD (EC 1.15.1.1), SIN-1, SNAP, MTT, catalase (EC 1.11.1.6), quercetin, rutin, sodium salicylate, and glutamate were purchased from ...
DGIST (President: Kuk Yang) announced on the 26th that Professor Park Jin-hee’s team at the Department of Physics and Chemistry generated new metal-organic frameworks (MOFs) and successfully ...
Formation of free radicals in golden hamster embryo (GHE) cells in the frozen living state by γ irradiation has been studied by electron spin resonance spectroscopy at 4.2 and 77 K. The relative ...
Aryl halides*1) with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a ...
Using a smart computational search, scientists discovered a catalyst ingredient that finally makes tough alkyl ketones behave the way chemists want. The reaction now runs cleanly and reliably, opening ...

Are free radicals really that bad for you?
Free radicals are highly reactive molecules that are missing an electron. They get a bad rap, but could they actually have ...
Chemically, “these are such molecules in the body that have unpaired electrons,” Rakshita explained. Here is how you can understand it better: Atoms contain an equal number of protons and electrons.
