A single bath full bleaching procedure for textile materials has been developed. In this procedure, following oxidative bleaching using hydrogen peroxide, the peroxide bath is converted to a reductive bath by addition of thiourea and bleaching continues without the need for a fresh bath for the reductive step. Such full bleaching is easy, economical and very effective in inducing improved white...

Thiourea (TU) application has been identified as a novel bioregulator technology, for imparting stress tolerance in crop plants. TU application has shown normal growth of Brassica juncea seedlings under salinity stress. In order to study the molecular mechanism underlying TU mediated response, genome wide transcriptome profiling of Brassica juncea seeds was undertaken. In one hour soaking time,...

Aerobic oxidation of alcohols in the liquid phase proceeded smoothly in the presence of nanoporous gold catalyst. The catalyst is reusable multiple times without leaching and loss of the catalytic activity. The reaction was applied successfully to a flow system. Adsorptions of O(2) and 1-phenylethanol into the AuNPore were confirmed by TDS analysis.

Catalytic oxidation of thiourea has been studied at alumina modified Pt electrode using cyclic voltammetry. The results indicate the suitability of alumina modified Pt electrode for voltammetric determination of thiourea. The catalytic peak currents are linearly dependent on the thiourea concentration in the range 2.5 × 10 – 7.0 × 10 M. The usefulness of the method was tested in determination o...

Several group 11 metal complexes with chiral thiourea organocatalysts have been prepared and tested as organocatalysts. The promising results on the influence of metal-assisted thiourea organocatalysts in the asymmetric Friedel-Crafts alkylation of indole with nitrostyrene are described. Better results with the metal complexes have been achieved because of the cooperative effects between the ch...

Cu electrorefining using a low-grade copper anode is desirable from the standpoint of electric power savings. electrolysis was carried out in an unagitated sulfate solution with anode, and effect impurity ions additives on passivation investigated. The time when firstly occurs shortened significantly containing 0.596 mol·dm−3 Ni2+ as somewhat As5+(0.053 mol·dm−3) or Bi3+(0.0005 ions. Sn2+(0.000...

Various Biginelli compounds (dihydropyrimidinones) have been synthesized efficiently and in high yields under mild, solvent-free, and eco-friendly conditions in a one-pot reaction of 1,3-dicarbonyl compounds, aldehydes, and urea/thiourea/acetyl thiourea using lithium-acetate as a novel catalyst without the addition of any proton source. Comparative catalytic efficiency of lithium-acetate and po...

Administration of alpha-naphthylthiourea (ANTU) to rats causes damage to pulmonary endothelial cells and possibly mesothelial lining cells that together may account for the massive pleural effusion characteristic of thiourea toxicity. Using 35S-thiourea as a model compound, the extent of binding of 35S to lung proteins correlated well with the extent of edema, suggesting that the extent of bind...

The reaction of copper(II) chloride and zinc(II) chloride with N-(2-methylphenyl)-3-(1'-salicylaldehydene-2'-imine-ethane)-butanamide(H2L2a) or (MPSB), N-(2-methylphenyl)-3-(1'-(3'-methoxysalicylaldehydene-2'-imine-ethane)-butanamide (H2L2b) or (MPMSB) and N-(2-methylphenyl)-3-(1'-(2'-hydroxyacetylene-2'-imine-ethane)-butanamide (H2L2c) (MPHB) leads to the formation of a series of new complexes...
