The solubilization of the hydrophobic dye Solvent Orange 2 has been measured in soluble complexes formed between mixed anionic/nonionic micelles and a strong polycation. In the system studied, comprising mixed micelles of sodium dodecyl sulfate and Triton X-100 with poly(dimethyldiallylammonium ...

The influence of heat treatment combined with microfiltration on the protein transfer from milk to cheese was investigated. Small-scale laboratory cheese-making experiments (10 L vat) showed that, upon adjusting coagulant and CaCl2 addition, curd-making was possible as long as β-lactoglobulin d...

Solubilized vat dyes wre separated by paper chromatography, using a methanolic solution of ammonia as solvent system. A system containing pyridine, isoamyl alcohol and ammonia, as well as a mixture of methanol and acetic acid were also used. Both descending and centrifugal chromatography were em...

Solubilization and depolymerization of carbohydrates by treatment of orange peel with dilute (0·06 and 0·5%) sulfuric acid at 100, 120 and 140°C has been investigated. The acid treatments solubilized a large portion of total carbohydrates in orange peel. However, only soluble sugars and sugar...

This paper reports a one-pot synthesis using radiation-induced grafting technique to modify biopolymer-based chitosan nanoparticles as a nanofiller for blending with poly(lactic acid) (PLA). Hydrophobic stearyl methacrylate (SMA) was grafted onto non-irradiated chitosan (CS0) and pre-irradiated ...

The extraction behavior of uranium (VI) from nitric acid medium was investigated using dinonyl phenyl phosphoric acid (DNPPA: monomeric form (HA), dimeric form (H2A2)) as extractant either alone or in combination with neutral oxodonors (S) such as tri-n-butyl phosphate (TBP), tris(2-ethylhexyl) ...

The photoredox reactions of biologically important phenols (p-coumaric acid, ferulic acid, thymol, quercetin and gallic acid) with the excited state [Ru(nbpy)3]2+ (nbpy = 4,4′-dinonyl-2,2′-bipyridine) complex proceed through photoinduced electron transfer reaction in DMSO and have been studied...

Gas chromatography with mass spectrometric detection was used to find the fraction of alcohols and acids present in pure beeswax from Apis mellifera. Some new compounds not described till now were found, such as a family of unsaturated linear fatty acids, several hydroxyacids and 1,2,3-propanetr...

The interaction between GABA receptors and benzodiazepine receptors at the molecular level was investigated on rat brain membranes in vitro, using 3H-diazepam binding assays. Stereoselective interaction was confirmed using the two stereoisomers R- and S-trans-4-methyl aminocrotonic acid. This fi...

Market analysts typically present their views on firms through publicly released recommendation reports and revisions, in which they ‘upgrade’ or ‘downgrade’ their stock picks. Traders can earn substantial profits if they have access to the information in these reports in advance of their pu...

Tip abrasion is a critical issue particularly for high-speed atomic force microscopy (AFM). In this paper, a quantitative investigation on the tip abrasion of diamond-like-carbon (DLC) coated tips in a high-speed metrological large range AFM device has been detailed. Wear tests are conducted on ...

An online survey of MTurk workers was used to obtain measures of average tipping likelihood as well as worker and service characteristics for each of 108 service occupations. Examination of the occupation-level relationships among these variables indicated that U.S. consumers are more likely to ...

Pertraction of lactic acid (LA) through supported liquid membranes (SLM) was investigated in a spiral channel flat sheet module using a liquid membrane with ionic liquid tetradecyl(trihexyl)phosphonium bis(2,4,4-trimethylpentyl)phosphinate (IL-104) which is an effective extractant of LA. The inc...

Toxicologic studies have been performed on a preparation of p-tertiary octylphenoxy-polyethoxy ethanols (Triton X-450) of average molecular weight of about 2000 with an ethylene oxide content averaging about 40.Administration of single oral doses of tritium-labeled material to rats and dogs indi...

A modified solvent impregnated resin (MSIR) was prepared by impregnation of sec-octylphenoxy acetic acid (CA-12) on styrene–divinylbenzene copolymer support (HZ818) after nitration of the benzene rings present in its structure. The MSIRs were characterized by thermogravimetric and Fourier Trans...

A series of derivatives of 1-(4-octylphenoxy)-3-(2H-tetrazol-2-yl)propan-2-one (3) and 1-(4-octylphenoxy)-3-(1H-tetrazol-1-yl)propan-2-one (4) was synthesized and tested for fatty acid amide hydrolase (FAAH) inhibitory potency and phase I metabolic stability. Introduction of certain substituents...

The effect of hydrogen bonds on chromatographic separations is demonstrated on the example of amino- and hydroxyanthraquinones and their O- and N-methyl derivatives. The RE values were used to chooose a set of new stationary phases and to demonstrate the dependence between the shift in the RF va...

Methods are presented for determining diisobutyl and diisopropylnaphthalenesulphonates in pesticides formulated as wettable powders or water dispersible granules. The dispersing agents were concentrated on anion-exchange cartridges and after removal of interfering substances eluted with methanol...

The hydroselenation of 1-organyl-1,3-butadiynes and 1,4-diorganyl-1,3-butadiynes with the sodium phenylselenolate anion, which was generated in situ by reacting diphenyl diselenide with NaBH4 in aqueous ethanol, results in the regio-, stereo- and chemoselective formation the 1-phenylseleno-4-org...

The formulation of most pesticides is proprietary and individual components are therefore not generally known. In a preliminary study, we identified six compounds that are often present in pesticides, of which 4-nonylphenyl-polyethylene glycol (NP-40) was found to be the most toxic. In this stud...
