Stability of Water/Poly(ethylene oxide)43-b-poly(ε-caprolactone)14/Cyclohexanone Emulsions Involves Water Exchange between the Core and the Bulk.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The formation of emulsions upon reverse self-association of the monodisperse amphiphilic block copolymer poly(ethylene oxide)43-b-poly(ε-caprolactone)14 in cyclohexanone is reported. Such emulsions are not formed in toluene, chloroform, or dichloromethane. We demonstrate by magnetic resonance

Monitoring of occupational exposure to cyclohexanone by diffusive sampling and urinalysis.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The present study was initiated in order to identify the best marker of occupational exposure to cyclohexanone among cyclohexanone and its metabolites in urine. To examine if diffusive samplers are applicable to personal monitoring of exposure to cyclohexanone in workroom air, the performance of

Synthesis of Pyridine-Dicarboxamide-Cyclohexanone Derivatives: Anticancer and α-Glucosidase Inhibitory Activities and In Silico Study.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

An efficient and practical method for the synthesis of 2,6-diaryl-4-oxo-N,N'-di(pyridin-2-yl)cyclohexane-1,1-dicarboxamide is described in this present study, which occurs through a double Michael addition reaction between diamide and various dibenzalacetones. The reaction was carried

Analysis of volatile organic compounds in pleural effusions by headspace solid-phase microextraction coupled with cryotrap gas chromatography and mass spectrometry.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Headspace solid-phase microextraction coupled with cryotrap gas chromatography and mass spectrometry was applied to the analysis of volatile organic compounds in pleural effusions. The highly volatile organic compounds were separated successfully with high sensitivity by the employment of a cryotrap

Quantification of organic solvents in aquatic toys and swimming learning devices and evaluation of their influence on the smell properties of the corresponding products.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Based on the observation that the characteristic odour of inflatable aquatic toys for children is predominantly caused by residues of hazardous organic solvents, the concentrations of cyclohexanone, isophorone and phenol were determined in a selection of 20 products obtained from online suppliers

Syn-anti isomerization of aldols by enolization.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

A variety of aldol adducts are shown to undergo efficient syn-anti isomerization in the presence of imidazole by an enolization mechanism. Isomerizations are high yielding and occur with little or none of the usual byproducts arising from competing elimination or retroaldol reactions. Most

Experimental and computational approaches to rationalise multicomponent supramolecular assemblies: dapsone monosolvates.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The monosolvate crystal energy landscapes of dapsone (DDS) including the solvents carbon tetrachloride, acetone, cyclohexanone, dimethyl formamide, tetrahydrofuran, methyl ethyl ketone, 1,2-dichloroethane, 1,4-dioxane, dichloromethane and chloroform were established using experimental and

[Pollution Characteristics and Emission Coefficient of Volatile Organic Compounds from Shoe-making Industry in Zhejiang Province].

Alleen geregistreerde gebruikers kunnen artikelen vertalen

To explore the pollution characteristics and emission coefficient of volatile organic compounds (VOCs) released from the shoe-making industry in Zhejiang province, this paper used the survey data of 490 shoe enterprises obtained in 2015 to analyze the current VOCs treatment status of shoe-making

The mechanism of the Baeyer-Villiger rearrangement: quantum chemistry and TST study supported by experimental kinetic data.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The mechanism of the Baeyer-Villiger rearrangement is modelled for the reaction of propanone with trifluoroperacetic acid, catalyzed by trifluoroacetic acid in dichloromethane, using three DFT methods (B3LYP, BH&HLYP and MPWB1K) and MP2. These results are refined and used to calculate the overall

Predictions of the EC50 for action potential block for aliphatic solutes.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Experiments were conducted to test the hypothesis that aliphatic hydrocarbons bind to pockets/crevices of sodium (Na(+)) channels to cause action potential (AP) block. Aliphatic solutes exhibiting successively greater octanol/water partitition coefficients (K (ow)) were studied. Each solute blocked

[Source Analysis and Environmental Health Risk Assessment of VOCs in Furniture Manufacturing].

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Regarding furniture manufacturing, scholars have only studied the sources of VOCs in the spraying process, yet the main concern is the release of VOCs after the completion of the manufacturing process and its impact on indoor air quality. Therefore, in this study, the sources of VOCs for the entire

Oxidation of Cyclohexane by Molecular Oxygen Photoassisted by meso-Tetraarylporphyrin Iron(III)-Hydroxo Complexes.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

The photochemical and photocatalytic properties of iron meso-tetraarylporphyrins bearing an OH(-) axial ligand and different substituents in the beta-positions of the porphyrin ring are reported. Irradiation (lambda = 365 nm) in the absence of dioxygen leads to the reduction of Fe(III) to Fe(II)

Percutaneous absorption of thirty-eight organic solvents in vitro using pig skin.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Percutaneous absorption is highly variable between chemicals but also within chemicals depending on exposure conditions and experimental set up. We tested a larger number of organic solvents with the same experimental set up, using skin from new-born piglets and static diffusion cells. Thirty-six

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Based on hazardous volatile organic compound (HVOCs) species recommended by the California Air Resources Board and Taiwan Environmental Agency(China), eight HVOCs species were focused on, namely benzene, toluene, xylene, ethylbenzene, styrene, dichloromethane, 1,1-dichloroethylene, and

Electrospinning of Grooved Polystyrene Fibers: Effect of Solvent Systems.

Alleen geregistreerde gebruikers kunnen artikelen vertalen

Secondary surface texture is of great significance to morphological variety and further expands the application areas of electrospun nanofibers. This paper presents the possibility of directly electrospinning grooved polystyrene (PS) fibers using both single and binary solvent systems. Solvents were
