bility unlikely for the following reasons: 1) Isopropanol was detected in the patient’s blood on more than one occasion during hospitalization. Specimens were drawn by different staff each time. Our current phlebotomy protocol specifically addresses the need to avoid isopropanol swab contamination. Considering the number of phiebotomists involved with the patient, it is difficult to support the...

The diffusion coefficient of isopropanol in alkaline medium using electrochemical methods on Pd electrode has been studied by linear sweep voltammetry (LSV) with different sweep rate and chronoamperometry in 1.0 M KOH solution containing 1.0 M isopropanol. Isopropanol oxidation on the Pd electrode is an irreversible charge-transport process and controlled by a diffusion process. The diffusion c...

UNLABELLED The aim of the study was to analyze the incidence of acetone and isopropanol in the blood of the deceased, and to assess cases in which the compounds have been detected with a focus on their origin and usefulness for medico-legal testimony. MATERIAL AND METHODS The study material consisted of results of tests detecting ethyl alcohol and reports of autopsies performed at the Departm...

Occupational exposure to isopropanol was studied in 12 workers by testing environmental air, alveolar air, venous blood, and urine during their work shift. Isopropanol, which ranged in environmental air between 7 and 645 mg/m3, was detected in alveolar air, where it ranged between 4 and 437 mg/m3, but not in blood or in urine. Alveolar isopropanol concentration (Ca) was significantly correlated...

BACKGROUND High cost of traditional substrates and formation of by-products (such as acetone and ethanol) in acetone-butanol-ethanol (ABE) fermentation hindered the large-scale production of biobutanol. Here, we comprehensively characterized a newly isolated solventogenic and xylanolytic Clostridium species, which could produce butanol at a high ratio with elimination of ethanol and conversion ...

Teh aim of dis work is to provide insight into alcohol-kerosene fuels and their promising use as an alternative in commercial aviation. A detailed chemical and physical experimental analysis is drawn, wif a focus on teh advantage of teh isopropanol-kerosene blend. Despite reported beneficial isopropanol effects on retarding fuel combustion, knocking prevention, and much lower emissions, few...

BACKGROUND Isopropanol is widely used by conservators to relax the creases and folds of parchment artefacts. At present, little is known of the possible side effects of the chemical on parchments main structural component- collagen. This study uses X-ray Diffraction to investigate the effects of a range of isopropanol concentrations on the dimensions of the nanostructure of the collagen compone...

Large amounts of the major storage proteins, beta-conglycinin and glycinin, in soybean (Glycine max) seeds hinder the isolation and characterization of less abundant seed proteins. We investigated whether isopropanol extraction could facilitate resolution of the low abundant proteins, different from the main storage protein fractions, in one-dimensional polyacrylamide gel electrophoresis (1D-PA...

The viscosities of alkanes (propane, isobutane, nonane), alcohols (ethanol, propanol, isopropanol, 2-butanol) and isopropanol + nonane mixtures were calculated using non-equilibrium and equilibrium molecular dynamics (NEMD and EMD) simulation methods. The nonane, isopropanol and nonane + isopropanol mixture simulations were performed in response to the First Industrial Simulation Challenge. Int...
