Dihydrogen, methane, and carbon dioxide isotherm measurements were performed at 1-85 bar and 77-298 K on the evacuated forms of seven porous covalent organic frameworks (COFs). The uptake behavior and capacity of the COFs is best described by classif

The in situ photolytic exchange of ethylene and hydrogen for carbon monoxide on cymantrene (CpMn(CO)3 , Cp = η5-cyclopentadienyl) and methylcymantrene (MeCpMn(CO)3, MeCp = monomethyl-η5-cyclopentadienyl) dissolved in subcritical and supercritical s

Xenon is the most reactive stable rare gas, and its chemical properties have been widely explored since the discovery of the first xenon-containing compound by Bartlett in 1962.1,2 Usually, extremely electronegative substances are required to make a

The development of electrocatalysts to generate hydrogen, with good activity and stability, is a great challenge in the fields of chemistry and energy. Here we demonstrate a "hitting three birds with one stone" method to synthesize less toxic metalli

We investigate the effects of zero-point vibrational motion on the nuclear magnetic shielding constants of a large number of organic molecules. The vibrational corrections include anharmonic contributions from the potential energy surface and harmoni

Recent kinetic measurements of the oxidation of linoleic acid by soybean lipoxygenase show that the thermal rate constants, kH ) 280 ((12) s -1 and kD ) 5.0 ((0.1) s -1 , are weakly temperature dependent within the temperature interval 30-50 °C. The

Photolyses of 2,3-bis(trimethylsilyl)-substituted methylenecyclobutenones 22−26 give essentially quantitative conversion to the allenylketenes 28−32 which have been isolated as long-lived species at room temperature. As predicted by molecular orb

Hydrogen bonds play critical roles in protein structure, stability, and function. Conventionally, hydrogen bonds are mainly determined by X-ray crystallography and NOE-based NMR spectroscopy in indirect manners. In recent years, it was demonstrated t

Phenol has been matrix-isolated in argon, nitrogen, and carbon monoxide. The magnitude of the shifts of key OH bands from gas-phase values indicates that phenol-matrix interactions increase in the series Ar < N/sub 2/ < CO. Phenol forms a 1:1 complex

The reduction has been effected by using a variety of Pd (palladium)-based catalysts. The typical procedure was to suspend 0.25 g of catalyst in 25 cc of an aqueous solution of sodium bicarbonate purged slowly with hydrogen gas. The sodium formate co
