Semiconducting organic-inorganic nanocomposites were judiciously crafted by placing conjugated polymers in intimate contact with inorganic tetrapods via click reaction. CdSe tetrapods were first synthesized by inducing elongated arms from CdSe zincblende seeds through seed-mediated growth. The subsequent effective inorganic ligand treatment, followed by reacting with short bifunctional ligands,...

The electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (CV) method.Results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: H2PO4- > HPO42-> SO42-. It’s revealedalso that the cathodic ...

A series of organic–inorganic hybrid thin films with different d 0 -metals (Y, Ti, Zr and Hf) 2,6-naphthalenedicarboxylic acid were prepared by molecular layer deposition (MLD) their optical properties explored.

A mild and green method has been developed for the preparation of coumarins derivatives through the one-pot reactions. In our study,various phenols and ethyl acetoacetate compound in which we used silica-supported boron sulfonic acid [SiO2/B(SO4H)3] as a new, highly efficient and tri-functional inorganic Brønsted acid catalyst were processed under solvent-free condition and thermal. The catalys...

Reaction 1 occurring with reaction 2 involves carbon dioxide fixation. Koepsell & Johnson (1942) obtained a cell-free extract from Clo8tridium butylicum which converts pyruvic acid into acetic acid, carbon dioxide and hydrogen, and requires phosphate for the reaction. Later Koepsell, Johnson & Meek (1944) found that inorganic phosphate is taken up and labile phosphate appears. The overall react...

* Present address, Department of Biochemistry, University of California, Berkeley 4, California. 1 The following abbreviations have been used; THF, tetrahydrofolic acid; lo-formyl-THF, N*o-formyltetrahydrofolic acid; 5,10-methenyl-THF, the cyclic N6-NrOimidazolinium derivative of 5-formyl-THF (anhydroleucovorin or anhydrocitrovorum factor) ; ATP, adenosine triphosphate; ADP, adenosine diphospha...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

The ability of aerosol particles to take up water before supersaturated activation is defined as hygroscopic growth. The particle hygroscopic growth factor (HGF) is required for calculations of aerosol optical properties. To represent HGF in real environments, it is desirable to initialize a thermodynamic water uptake model with ambient aerosol measurements. The assumptions needed to adapt meas...

The terms acid neutralizing capacity (ANC) and alkalinity (Alk) are extensively employed in the characterization of natural waters, including soft circumneutral or acidic waters. However, in the presence of organic acids, ANC measurements are inconsistent with many conceptual definitions of ANC or Alk and do not provide an adequate characterization of the acid-base chemistry of water. Knowledge...

BACKGROUND Arsenic induces neural tube defects in several animal models, but its potential to cause neural tube defects in humans is unknown. Our objective was to investigate the associations between maternal arsenic exposure, periconceptional folic acid supplementation, and risk of posterior neural tube defect (myelomeningocele) among a highly exposed population in rural Bangladesh. METHODS ...
