Molecular dynamics simulations and fluorescence anisotropy decay measurements are used to investigate the rotational diffusion of anthracene in two organic solvents—cyclohexane and 2-propanol—at several temperatures. Molecular dynamics simulations of 1 ns length were performed for anthracene in cyclohexane ~at 280, 296, and 310 K! and in 2-propanol ~at 296 K!. The calculated time constants for ...

Zusammenfassung n‑Propanol wird endogen unter Ethanoleinfluss gebildet. Die Quelle des endogenen n‑Propanols ist bislang unbekannt. Mögliche Entstehungsorte sind der Darm oder die Leber. In dem hier dargestellten Pilotversuch wurde einer Testperson ( n = 1) Ethanol intravenös (i.v.) verabreicht, um den Magen-Darm-Trakt zu umgehen. Während Versuchs konnte mit steigender Ethanolkonzentration eine...

Aminoalcohols have been addressed as activating buffers for alkaline phosphatase. However, there is no record on the buffer activation regarding organophosphorus hydrolase (OPH). Here we reported the activating effects of aminoalcohols on OPH-catalyzed hydrolysis of diisopropylfluorophosphate (DFP), an analog molecule of G-type warfare agents. The kinetic parametors kcat, Vmax and kcat/Km in th...

Noni (Morinda citrifolia) fruit is a well-known plant used as traditional medicine for preventing some diseases because of its abundance in chemical compounds. This research aimed to determine the phytochemical concentration, composition, and antifungal activity M. citrifolia extract. was extracted with methanol then distilled water partition Subsequently, extract fractionated using various non...

This article discusses the performance of ZrO2-supported size-selected Pt nanoparticles for the decomposition of methanol, ethanol, 2-propanol, and 2-butanol. The potential of each alcohol for the production of H2 and other relevant products in the presence of a catalyst is studied in a packed-bedmass flow reactor operating at atmospheric pressure. All the alcohols studied show some decompositi...

Two novel peroxo titanium complexes, Li(2)(NH(4))(4)[Ti(2)(O(2))(2)(cit)(Hcit)](2).5H(2)O and Zn(NH(4))(4)[Ti(4)(O(2))(4)(Hcit)(2)(cit)(2)].12H(2)O (cit = citrate), show encouraging results in the photochemical oxidation of 2-propanol.

Abstract This study aims to investigate the viscosity of binary mixtures water with different monoalcohols and polyalcohols. The values methanol, ethanol, 1-propanol, 2-propanol were taken from a published by Herraez Belda (2004). for ethylene glycol, glycerin, sorbitol measured using similar protocol. mixture is expressed as function molar fraction alcohols that ranges 0 (pure solvent, in this...
