The synergism between protocatechualdehyde (PAL, 3,4‐dihydroxy‐benzaldehye) and rare earth cerium(IV) ion (Ce4+) on the corrosion of cold rolled steel (CRS) in 1.0 M hydrochloric acid (HCl) solution has been investigated by weight loss and potentiodynamic polarization methods. The results reve...
A novel ruthenium(II) complex [Ru(dppt)2]2+ (dppt=bis[3-(1,10-phenanthroline-2-yl)-5,6-diphenyl-as-triazines) labeled as Ru(II) is assembled on CdS and Cu2O electrode to prepare Ru(II)/CdS photoanode and Ru(II)/Cu2O photocathode for the oxidation of ascorbate (AA) and the reduction of dioxygen (...
The preparation and characterization of high‐molecular weight diphenyl oxide‐ and diphenyl sulfide‐novolacs are described. The polymerization of diphenyl oxide with 2 equivalence of formaldehyde proceeded to give the corresponding polymer (2) (Mn: 160,000, Mw/Mn: 29.1) in good yield. Further,...
New thermoplastic polyurethane elastomers (TPUs) were obtained by a one-step melt polyaddition from 30, 45 and 60 mol% aliphatic polycarbonate diol of M n = 2000 g mol−1 (Desmophen® C2200, Bayer), 1,1′-methanediylbis(4-isocyanatocyclohexane) (HMDI) or 1,6-diisocyanatohexane (HDI) and ...
Lipid-based nanoemulsions are a cheap and elegant route for improving the delivery of hydrophobic drugs. Easy and quick to prepare, nanoemulsions have promise for the delivery of different therapeutic agents. Although multiple studies have investigated the effects of the oil and preparation cond...
By reaction of cerous nitrate with oxalic acid in the presence of surfactant polyvinylpyrrolidone at room temperature, lamellar cerium oxalate complex was obtained facilely. After calcination, CeO2 was produced, which inherited its parents’ morphology and was assembled by porous micro-nano lame...
Zinc sulphide thin films were deposited by chemical spray pyrolysis technique. The films were deposited at substrate temperatures of 300, 350 and 400 °C using 0.1 M zinc chloride, 0.1 M thiourea and 0.01 M ethylenediaminetetraacetic acid disodium salt (EDTA). The films have moderate transmittan...
A new nano-structured bismuth(III)-imprinted polymer was prepared by copolymerization of Bi(III)-methylene succinate complex and ethylene glycol dimethacrylate in acetonitrile via precipitation polymerization technique. The polymeric nanoparticles were then used as the Bi3+ selective modifier of...
In the present paper we describe a robust and simple method to measure dissolved iron (DFe) concentrations in seawater down to
A novel strategy for the construction of a disposable integrated amperometric immunosensor for the sensitive and rapid determination of lipoprotein(a) (Lp(a)), an important predictor of cardiovascular disease risk, in human serum is reported. The approach uses a sandwich format involving the cov...
Na-nitrilotriacetic acid (Na 3 NTA) and Fe-nitrilotriacetic acid (FeNTA) have both been described to cause tumors in the urinary tract of rodents. However, these effects were observed using different modes of administration at extremely different dose levels and explained by different me...
The synergistic effects of pentaerythritol (PER) with aluminum hypophosphite (AHP) in halogen‐free flame retardant EVA/AHP/PER composites have been studied by cone calorimeter test (CCT), limiting oxygen index (LOI), vertical burning test (UL‐94), thermogravimetric analysis (TGA), and scanning...
A new rhodamine functionalized fluorogenic Schiff base CS was synthesized and its colorimetric and fluorescence responses toward various metal ions were explored. The sensor exhibited highly selective and sensitive colorimetric and “off–on” fluorescence response towards Al3+ in the presence o...
Copper was pre-concentrated from a large volume of its aqueous solutions using disodium 1-nitroso-2-naphthol-3,6-disulphonate (nitroso-R salt) and tetradecyldimethylbenzylammonium chloride (TDBA + Cl - ) on microcrystalline naphthalene in the pH range 5.5-7.8. After filtration, t...
Copper is quantitatively retained by 2-nitroso-1-naphthol-4-sulfonic acid and tetradecyldimethylbenzylammonium chloride on microcrystalline naphthalene in the pH range 7.1–10.7 from large volumes of aqueous solutions of various samples. After filtration, the solid mass consisting of a copper co...
The effect of butanol and benzyl alcohol on the critical micelle concentration and the degree of ionization of micelles of tetradecyldimethylbenzylammonium chloride has been studied conductometrically in the temperature range of 5 to 40°C at 5°C intervals. The results indicate that some self-a...
A protein with a mol.mass of 51,000 (ThcE) that was induced in Rhodococcus sp. N186/21 during assimilation of thiocarbamate herbicides, atrazine, ethanol, propanol, glycerol, propionaldehyde or ethanolamine was identified by two-dimensional electrophoresis. The thcE gene was cloned and sequenced...
A series of lanthanide(III) complexes with chelidamic acid ligand, [Ln(C 7 H 2 NO 5 )·3H 2 O] n ·nH 2 O (Ln=La (1), Y (2), Sm (3), and Nd (4)), [Gd 2 (C 7 H 2 NO 5 ) 3 ·4H 2 O] n ·2nH ...
