background: methanol poisoning is one of the most important poisoning due to drinking of illegal and non-standard alcoholic beverage in some countries. relatively limited studies have been carried out to identify the prognostic factors in methanol poisoning. materials and methods: we performed a retrospective study on acute methanol-intoxicated patients, which were admitted on the loghman hakim...

effect of oil neem seed extract and the neem kernel powder mixed with methanol 85% and ethanol 95% were investigated on two spotted spider mite (tetranychus urticae) under greenhouse (25 ± 5 °c and 40 ± 10% r. h.) and laboratory conditions. mortality percent of each above-mentioned solvent in different concertrations (0.03, 0.06, 0.09, 0.12, 0.15, 0.2, 0.3 and 0.5%) by three methods (leaf dip, ...

Copper and zinc were introduced into mesoporous siliceous matrices with the goal of obtaining model methanol synthesis catalysts with intense interaction between copper and the ZnO promoter. The preparation methods included various aqueous routes starting from acetate solutions (into MCM-48) and a route involving an organometallic step—thermolysis of a liquid heterocubane of Zn4O4 type ([CH3ZnO...

Density functional theory (B3LYP-D3, M06-2X) has been used to calculate the structures, interaction energies and vibrational frequencies of a set of 93 methanol-water clusters of different type (cubic, ring, spiro, lasso, bicyclic), size and composition. These interaction energies have been used within the framework of the Quantum Cluster Equilibrium Theory (QCE) to calculate cluster population...

Methanol catalysis meets chemistry under confined conditions. Methanol is regarded as one of the most important future energy sources. ZnO/Cu composite materials are very effective in heterogeneous catalysis for methanol production due to the so-called strong metal-support interaction effect (SMSI). Therefore, materials of superior structural design potentially representing model systems for he...

Transition metal hexacyanocobaltates are porous materials with open metal sites and a wide variety of pores. In this work, manganese(II) and cobalt(II) hexacyanocobaltates(III) have been selected to explore the interactions between the open metal sites located in their pores and the guest molecules: hydrogen, carbon dioxide, water and methanol. An experimental setup was designed and implemented...

The effect of solute-solvent interaction on molecular structure and reaction dynamics has been a target of intense studies in solution-phase chemistry, but it is often challenging to characterize the subtle effect of solute-solvent interaction even for the simplest diatomic molecules. Since the I2 molecule has only one structural parameter and exhibits solvatochromism, it is a good model system...

The three pulse photon echo peak shift technique was used to study solvation dynamics in acetonitrile ͑297 K͒, methanol ͑297 and 323 K͒, and ethylene glycol ͑297 and 397 K͒ utilizing the tricarbocyanine laser dye, IR144, as a probe. The spectral density, ␳͑␻͒, governing the solute-solvent interaction was obtained for each solvent and temperature through numerical fitting of the three pulse photon echo ...

The structures of the intact synaptosomal plasma membrane vesicles (SPMVs) isolated from bovine cerebral cortexs, and the outer and the inner monolayer separately, were evaluated with 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1,3-di(1-pyrenyl)propane (Py-3-Py) as fluorescent reporters and trinitrophenyl groups as quenching agents. The methanol increased bulk rotational and lateral mobilities of S...
