Biological and chemocatalytic processes are tailored in order to maximize the production of sustainable biodiesel from lignocellulosic sugar. Thus, the combination of hydrotalcite-supported copper(II) and palladium(0) catalysts with a modification of the fermentation from acetone-butanol-ethanol to isopropanol-butanol-ethanol predictably produces higher concentrations of diesel-range components...

Well-defined dimeric or polymeric Pd(0) complexes [Pd(μ-(iPr)PCHP)](n) (n = 2 or ∞) containing the bridging ligand α,α'-bis(diisopropylphosphino)-m-xylene ((iPr)PCHP) are produced under mild conditions when the cyclometallated PCP pincer complex ((iPr)PCP)Pd-OH reacts with methanol or isopropanol.

The 75% isopropanol-soluble material from the endosperm of the legume-seed of Gleditsia triacanthos was isolated. The material extracted with boiling water was fractionated by ion-exchange chromatography and characterized. Besides minor amounts of galactomannans, major proportions of arabinans and/or arabinogalactans appear.

Glycopeptide enrichment is a crucial step in glycoproteomics for which hydrophilic interaction chromatography (HILIC) has extensively been applied due to its low bias towards different glycan types. A systematic evaluation of applicable HILIC mobile phases on glycopeptide enrichment efficiency and selectivity is, to date, however, still lacking. Here, we present a novel, simplified technique fo...

UNLABELLED Soybeans are an important legume crop that contain 2 major storage proteins, β-conglycinin and glycinin, which account about 70- 80% of total seed proteins. These abundant proteins hinder the isolation and characterization of several low abundant proteins in soybean seeds. Several protein extraction methodologies were developed in our laboratory to decrease these abundant storage pro...

BACKGROUND The risk of wound infection after elective inguinal hernia repair depends on several factors. One of the most important factors is the preoperative skin preparation. The use of antisepsis is performed to reduce the risk of surgical site infections (SSIs) and to remove causing organisms. This work compares two different agent forms for preoperative skin preparation to prevent SSIs. ...

The photoionization of isopropanol (i-PrO H) at 11.7 e V has been investigated in the NBS high pressure photoionization mass spectrometer over the pressure range 0.1 to approximately 200 millitorr_ The major primary ion, CHaCHOH+, reacts with a total rate coefficient of 1.1 ± 0_1 X 109 cma/molecule-s to yie ld mainly (i-PrOH)H+ and CH3(i-Ca H,)COH+ _ At pressures in excess of a few millitorr co...

Isopropanol oxidation is studied on platinum single crystals using electrochemical techniques and FTIR spectroscopy at different isopropanol concentrations. found to be facilitated by the presence of adsorbed OH electrode surface, which reacts with an molecule yield alkoxide. Thus, when sulfuric acid used as supporting electrolyte instead perchloric acid, currents diminish drastically since sul...

The chemical industry includes a wide range of factories focused on obtaining final products as: (i) plastics; (ii) fibers; (iii) rubber; (iv) perfumery and cosmetic products; (v) cleaning products. Although the level safety in activities installations this sector is very high, use dangerous substances implies an increased risk suffering accident involving emission hazardous substances, as well...
