The effect of subcutaneous naloxone administration on the consumption of a weak ethanol solution in rats on the three consecutive days (testing days) was investigated using a behavioral paradigm which includes a first forced ethanol exposure (conditioning ...
A rapid transformation of eicosapentaenoic acid is initiated upon disintegration of cells of the marine diatom Stephanopyxis turris. In contrast to any other fatty acid cleaving activity known, this diatom releases a blend of chlorinated C8-hydrocarbons in ...
Although a multitude of halogenated compounds are naturally produced, interest in biodegradation of these often toxic compounds has mainly been driven by anthropogenic contamination of soils and aquifers with huge amounts of chlorinated solvents (tetra- an ...
The kinetics of the formation of trihalomethanes (THMs) and of chlorine consumption for the chlorination of natural organic matter with an excess of chlorine (50 muM > Cl-2 > 210 muM) was investigated. THM precursors could be divided into a fast and a ...
Thin film gas sensors made of nanocomposite MWCNT center dot SnO2(1:66), semiconductor compound WO3 center dot SnO2(1:9), and also multicomponent structure MWCNT center dot SnO2(1:66)/WO3 center dot SnO2(1:9) have been fabricated by high-frequency magnetro ...
Multi-walled carbon nanotubes (MWCNTs) were successfully coated with tin-dioxide (SnO2) nanopartides using both hydrothermal process and sol-gel technique under different solvent conditions. The obtained MWCNTs/SnO2 nanocomposites had the weight ratio of t ...
Homochiral Diels-Alder cyclodimerization of (+/-)-6-ethenyl-7-oxabicyclo[2.2.1]hept-5-en-2-endo-ol followed by oxidation gives (1RS,4RS,4aSR,4bSR,5RS,8RS,8aRS)-8a-ethenyl-1,3,4a,4b,5,6,8,8a,9-decahyd ro-11,4:5,8-diepoxyphenanthrene-2,7-dione (18). Selectiv ...
The objective of this study was to remove halides from waters by silver nanoparticles (AgNPs) and hydrogen peroxide (H2O2). The experimental parameters were optimized and the mechanism involved was also determined. The AgNP/H2O2 process proved efficacious ...
Thin film ethanol sensors made from alpha-Fe2O3 decorated with multiwall carbon nanotubes (MWCNTs) were manufactured by the electron beam deposition method. The morphology of the decorated alpha-Fe2O3/MWCNTs (25:1 weight ratios) nanocomposite powder was in ...
Tris(β-diketonato)europium(III) with a series of variably fluorinated ligands derived from 3,5-heptanedione were synthesised with the aim of determining their hydration state under extraction conditions. The number of coordinated water molecules was determ ...
