One area of focus has been the diffusion coefficients of gases like carbon dioxide and methane in various solvents, including water and ethanol. A study employed both nuclear magnetic resonance ...

In a previous study, oxygen quenching of naphthalene showed evidence of static quenching, although the mechanism was not known. The earlier work was limited to low oxygen concentrations (∼2 mM) in ...

A holey carbon material with ordered sub-nanometer hole defects was synthesized from oxidative cyclodehydrogenation of a polyhexaphenylbenzene precursor. Band gap of around 2.2 eV is formed due to the ...

The hydrogenation of ketones to alcohols using isopropanol as a hydrogen source has attracted wide attention because isopropanol is a common and cheap solvent; isopropanol and the by-product of the ...

After that, the gum was washed for 30 min in cyclohexane (Sigma-Aldrich, UK), filtered through a filter paper, and dried for 45 min in ambient conditions. To finish, the dry gum was washed in ethanol ...
