The nature of MoO3 and MoO3/Al2O3 ultrathin films supported on Mo~110! and their interactions with CH3OH have been investigated using surface science techniques. The ultrathin (,50 Å) films were characterized by Auger electron spectroscopy, low energy electron diffraction, and high resolution electron energy loss spectroscopy ~HREELS! of their phonon vibrational modes and electronic transition ...

Ab initio calculations at the B3LYP/aug-cc-pVDZ, B3PW91/aug-ccpVDZ, MP2/aug-cc-pVDZ, B3LYP/6-311 G(2d,2p), B3PW91/6-311 G(2d,2p), and MP2/6-311 G(2d,2p) levels are performed for the IR spectra of isolated water and methanol molecules and hydrogen-bonded water–methanol, methanol–water, and methanol–methanol complexes. Frequency shifts and changes in intensities are obtained for the proton donor ...

The largest of the gene clusters coding for proteins involved in methanol oxidation is the cluster mxaFJGIR(S)ACKLDEHB. Disruption of most of these genes leads to lack of growth on methanol. The previous results showed that the mutant lacking MxaD grows on methanol although at a low rate. This is explained by the low rate of methanol oxidation by whole cells. The specific activity of methanol d...

background: herbal distillates had been used for many centuries as herbal medicine in traditional persian medicine. recently, some studies claimed the presence of methanol in different types of herbal distillates which can cause different complications or even death as methanol is highly toxic. the main purpose of this study was to determine methanol content in the commonly-used industrial herb...

SAPO-34 is a commercially-implemented silicoaluminophosphate catalyst for selective high yield production of ethene and propene from methanol, but temperature regeneration in the presence steam leads to its deactivation. A comprehensive investigation effect prolonged hydrothermal treatment on structure properties explains changes catalytic methanol-to-olefins (MTO) performance. Microcrystalline...

The effect of pretreatment conditions on the oxidation state and activity of micelle-synthesized Pt nanoparticles supported on ZrO2 was studied for methanol decomposition and oxidation reactions. An O2-pretreatment is observed to be effective for producing clean, stable, and active nanoparticles. Pt-oxide species formed during such pretreatments were found to have little influence in methanol d...
