EPR study of gamma irradiated 2,5-di-tert-butyl-hydroquinone single crystals

Hydrogen‐Bond‐Assisted Solution Discharge in Aprotic Li–O2 Batteries

“…Antioxidants, widely used in the food industry, that can inhibit the oxidation of organics by stabilizing the free radicals, would be good choices. [ 13 ] Therefore, an excellent antioxidant with hydroxyl group (OH) could not only withstand the harsh operating environment in the Li–O 2 battery by stabilizing the reactive free radicals (O 2 − and LiO 2 ), but also increase the solubility of the reduced oxygen‐containing species (O 2 − , LiO 2 , and Li 2 O 2 ) via hydrogen‐bond‐assisted solvation to promote the solution discharge. However, the potential functions of the hydrogen bonds and antioxidants in Li–O 2 batteries have rarely been investigated, so exploration works are required to unearth their mysterious efficacy.…”

EPR and FT-IR spectroscopic studies of l-lysine monohydrochloride and l-glutamic acid hydrochloride powders

“…Therefore, the EPR technique has been widely used for the identification of irradiation damage centers in many substances, including drugs, amino acid and derivatives [7][8][9][10][11][12][13][14][15]. The X-irradiated single crystals of L-lysine monohydrochloride dehydrate have been investigated at 66 K by EPR and ENDOR technique [1].…”

Solubility of 2,5-Di-tert-butylhydroquinone and Process Design for Its Purification Using Crystallization

“…The mole fraction solubility of DTBHQ (x1) in pure solvents and the binary solvent mixture was calculated using eq.1 (1) where Msolute, Msolvent, and Mwater are the molecular weight of DTBHQ, solvent, and water respectively, w denotes the mass fraction of ethanol in an ethanol and water mixture, and w is 1 for pure solvent. Every one solubility data point was the average of three parallel measurements under the same condition.…”

“…1 It is colourless, of low toxicity, and has shown excellent end-use performance. Its demand has been on the increase in recent years, in particular in the manufacture of transparent or white plastic products.…”
