this paper reports results of a study regarding the activities of nano structure mn/γ-al2o3 and γ-al2o3 catalysts for oxidation of 2-propanol (as a model of volatile organic compound). nanostructure of catalysts was revealed using xrd, sem and tem techniques. catalytic studies were carried out in u-shaped packed bed reactor under atmospheric pressure and at the reaction temperature of 150- 500°...

Alcohol (methanol, ethanol, 1-propanol, 2-propanol and 1-butanol) and water vapor adsorption in zeolitic imidazolate frameworks (ZIF-8, ZIF-71 and ZIF-90) with similar crystal sizes was systematically studied. The feasibility of applying these ZIF materials to the recovery of bio-alcohols is evaluated by estimating the vapor-phase alcohol-water sorption selectivity.

Metal-catalyzed oxidation of proteins represents an important pathway of post-translational modification. We utilized human growth hormone (hGH), a protein with a well defined metal-binding site, to study the detailed mechanism of metal-catalyzed oxidation by ascorbate/Cu(II)/O2. Particularly His18 and His21 within the metal-binding site were oxidized, predominantly to 2-oxo-His with the incorp...

In this study, CeO2 hollow spherical nanoparticles, CeO2/SiO2 @ CeO2 core/shell composites,and hollow CeO2/SiO2 sensors were synthesized and their microstructures were researched byFT-IR, XRD, FESEM, EDX and BET analyses. The peaks observed in the FT-IR spectra of the synthesizedsamples corresponded to Ce-O stretching vibration (ca. 566 cm-1) and O-Si-O bendingvibration (ca. 470 cm-1). XRD diff...

Hand eczema is a common occupational skin disease in healthcare workers. This is often the result of repeated contact with irritants, such as water; however, contact allergy can also be the underlying cause. In this report, we describe a patient with occupational hand eczema, caused by contact allergy to 1-propanol (CAS no. 71-23-8; synonyms n-propanol and n-propyl alcohol), which was present i...

Esters are organic compounds that widely used even on an industrial scale, so their production has been extensively investigated. The aim of this work is to carry out the optimization process esterification propionic acid with lower monohydric alcohols. influence amount catalyst (H2SO4), size and structure alcohol, a-substituent, molar acid/alcohol ratio temperature were descending order reacti...

Context. The primary alcohol n-propanol (i.e., normal-propanol or propan-1-ol; C 3 H 7 OH) occurs in five different conformers: Ga, Gg, Gg' , Aa, and Ag. All rotational spectra of the three conformers G family are well described, making astronomical search their spectroscopic signatures possible, as opposed to those Aa Ag conformers. Aims. Our goal is facilitate detection by characterizing spec...

Vancomycin-resistant enterococci (VRE) may be spread within a hospital via the contaminated hands of the healthcare worker. Effective hand disinfectants are necessary to break chains of transmission. We determined the bactericidal activity of 1-propanol, chlorhexidine digluconate (0.5 and 4%). Sterillium (45% 2-propanol, 30% 1-propanol and 0.2% mecetronium etilsulphate), Skinsept F (70% 2-propa...

Detection of lung cancer biomarkers (LCBs) from exhaled breath in the early stage can lower mortality. We report a highly sensitive dealuminated zeolite Y (DaY)/SnO2 nanoparticle (NP)-based sensor for detection LCBs at low concentrations. The sensing performances were tested with 200 ppb propanol, formaldehyde, and toluene different operating temperatures 175 to 300 °C. was found be efficient p...
