Cyanide based silver electroplating is a low-cost reliable and well-established process for metal deposition. However, delicate handling during the process is needed because of the high toxicity of cyanide, for the persons and the environment. Uracil based silver electrodeposition got the attent...

In the present study, surface functionalized mannan sulphate silver nanoparticles (MS-AgNPs) were prepared and assessed for their wound healing potential. 20 nm sized, spherical MS-AgNPs were prepared by one pot synthesis approach wherein the sulphated polysaccharide mannan sulphate (MS) played ...

Rheology of bioceramic bone cements is usually described as properties of ceramic slurries, neglecting the self-setting character of these materials. In our studies calcium sulphate based bone cements with Ag+, Mg2+ and Mg2+/CO32- modified hydroxyapatite were investigated. Despite of expectation...

The semiconductor properties of chalcopyrite during leaching in sulfate solutions in the presence of silver have been investigated. A combination of Mott-Schottky plots and potentiodynamic polarisation was used to determine the transformations of the chalcopyrite surface as the potential was cha...

In this work, combined techniques were utilized to interpret the catalytic mechanism of Ag+ ions in sulfuric acid-ferric sulfate system of chalcopyrite. Density functional theory (DFT) calculations indicated the favorable adsorption of Ag+ ions on reconstructed (001)-S and (112)-S surfaces of ch...

The complexation behavior of reactive and nonreactive N-substituted 1-amino-5-isocyanonaphthalene (ICAN) derivatives was studied in the presence of Ag(I) ions by UV–vis, steady-state and time resolved fluorescence measurements. The effect of ligand, solvent and counterion is covered. The equili...

Positively charged polyhexamethylene guanidine hydrochloride-stabilized silver nanoparticles (PHMG-AgNPs) were prepared and applied as a colorimetric probe for single-step determination of pyrophosphate and sulfate. The approach is based on the nanoparticles aggregation leading to change in thei...

We synthesized various cuboid-type tungsten trioxide (WO3) particles using a hydrothermal method followed by calcination at various temperatures between 200 and 500 °C. Visible-light photocatalysis of these particles was investigated for oxygen (O2) evolution from water in the presence of sacri...

The tactic of embedding functional nanomaterials into ultrafiltration (UF) membranes has been investigated in order to augment the integrated properties of the hybrid membranes. Mixing of hydrophilic inorganic nanoparticles or nanofillers into the polymeric membranes to form organic-inorganic na...

The “non-hydrolyzing” bacterial UDP-N-acetylglucosamine 2-epimerase catalyzes the reversible interconversion of UDP-N-acetylglucosamine (UDP-GlcNAc) and UDP-N-acetylmannosamine (UDP-ManNAc). This homodimeric enzyme is allosterically activated by its substrate, UDP-GlcNAc, and it is thought tha...

Neisseria meningitidis serogroup A non-hydrolyzing uridine 5′-diphosphate-N-acetylglucosamine (UDP-GlcNAc) 2-epimerase (NmSacA) catalyzes the interconversion between UDP-GlcNAc and uridine 5′-diphosphate-N-acetylmannosamine (UDP-ManNAc). It is a key enzyme involved in the biosynthesis of the c...

A new metabolite, namely 2-acetamidoglucal, has been found in the urine of a patient with sialuria in addition to the metabolites N-acetylneuraminic acid, N-acetylmannosamine, N-acetylglucosamine and N-deoxy-2,3-dehydro-Nacetylneuraminic acid reported earlier. The structure has been identified b...

A novel approach for the preparation of oligonucleotides carrying amino groups at the 3′-end is described. Several CPG supports having aminoalkyl groups and 3′-amino-2′, 3′-dideoxynucleosides linked through base-labile carbamate linkages such as 2-(2-nitrophenyl)ethoxycarbonyl and fluorenylm...

We have attempted to stress the major areas of chromatographic techniques for carbamate analyses and also to illustrate the influence of carbamate moiety substituents on chromatographic behavior.The remarkable versatility of chromatographic techniques, as demonstrated by their many applications ...

The novel urea primaquine derivatives 3 were prepared by aminolysis of primaquine benzotriazolide 2 with several hydroxyamines and ethylendiamine, while carbamates 4 were synthesized from the same precursor 2 and alcohols. All compounds are fully chemically characterized and evaluated for their ...

A series of amino, amidino, and aminomethyl derivatives of benzene and cyclohexane were investigated for their inhibitory effect on the activation of trypsinogen. In agreement with earlier reports, amidines were generally much more potent than amines. p-Amidinophenylpyruvic acid, a newly synthes...

The formation of an enzyme-inhibitor adduct between bovine trypsin and [2-13C]p-amidinophenylpyruvic acid has been investigated by 13C NMR spectroscopy. The observation of a resonance at 100.8 ppm demonstrates that the hemiketal formed between the hydroxyl of serine-195 and the 2-13C carbon of p...

The adverse effects of environmental toxicants such as copper and arsenic occur due to the generation of reactive oxygen species. Recent study also reported that both copper (Cu) and arsenic (As) may alter muscle regeneration. In order to assess the toxic effects of copper and arsenic on chicken...

Sodium arsenite (NaAsO2) was especially used as a dormant spray to control grapevine trunk diseases (GTDs) in European vineyards until 2003 when it was banned. It was an efficient product but it was banned due to high risk for human health and the environment. Now, as one of the consequences wit...

BackgroundSub-chronic arsenic (arsenite) exposure-induced oxidative toxicity leads to adverse effects in various organ systems, especially the kidney. Copper sulphate (Cu2+), known for its extensive uses in agriculture, has also been reported to have pro-oxidation properties. Both of these two p...
