Collisions of low-energy electrons with isopropanol
We report measured and calculated cross sections for elastic scattering of low-energy electrons by isopropanol (propan-2-ol). The experimental data were obtained using the relative flow technique with helium as the standard gas and a thin aperture as the collimating target gas source, which permits use of this method without the restrictions imposed by the relative flow pressure conditions on h...
متن کاملActivity of ceftaroline against Enterococcus faecium PBP5.
The opportunistic human pathogen Enterococcus faecium overproduces the low-affinity PBP5. In clinical strains, mutations in PBP5 further reduce its acylation rate by β-lactams. Previous studies have reported that ceftaroline had poor inhibitory activity against β-lactam-resistant E. faecium strains. In this study, we show that ceftaroline exhibits killing activity against our laboratory-derived...
متن کاملIsopropanol exposure: environmental and biological monitoring in a printing works.
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...
متن کاملEffects of isopropanol on collagen fibrils in new parchment
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...
متن کاملEffective isopropanol–butanol (IB) fermentation with high butanol content using a newly isolated Clostridium sp. A1424
BACKGROUND Acetone-butanol-ethanol fermentation has been studied for butanol production. Alternatively, to achieve acetone-free butanol production, use of clostridium strains producing butanol and 1,3-propanediol (1,3-PDO) from glycerol, natural and engineered isopropanol-butanol-ethanol (IBE) producers has been attempted; however, residual 1,3-PDO and acetone, low IBE production by natural IBE...
