Uranium becomes soluble and mobile under oxidizing conditions in aqueous environment, and presence of complexing agents with uranium increase this mobility. Existence of such conditions in groundwaters of Ayrakan and Cheshmeh Shotori areas has led to oxidation, solubility and mobility of uranium minerals. Hydrogeochemical study of uranium in the study areas reveals the presence of bicarbonate i...

Botulinum toxin type A is a high molecular weight protein complex containing active neurotoxin and complexing proteins, the latter of which, it is believed, protect the neurotoxin when in the gastrointestinal tract, and may facilitate its absorption. Comparisons of conventional botulinum toxin type A drugs that include complexing proteins with the complexing protein-free formulation of Xeomin(®...

The distribution of adenosine deaminase and adenosine deaminase complexing protein in rabbit heart has been compared using immunohistochemical staining procedures. Sections (4-5 microns) of tissue fixed in Clarke's solution or paraformaldehyde and embedded in paraffin were stained by the peroxidase anti-peroxidase method for adenosine deaminase or complexing protein, using affinity purified ant...

Deposition parameters determine the characteristics of semiconductor films in electrodeposition. Thus, it is essential to understand effect deposition on electrodeposited film for fabricating suitable fitting various applications. In this work, morphological and compositional properties delafossite CuFeO2 film, according parameters, were studied. The was fabricated by galvanostatic electrodepos...

Different complexing agents were used to prepare Ni–Mg–Zn ferrite with the composition formula Ni0.2Mg0.2Zn0.6Fe2O4 via sol–gel method, which included citric acid, oxalic egg white, and EDTA. The without agent was also prepared as a comparison. chemical phases of samples analyzed by X-ray diffraction (XRD), indicated that had spinel phase structure. lattice constants are in range 8.3980–8.4089 ...

The humic substance consists of acid, fulvic and humin. Humic acid is a useful metal complexing agent, good dispersant, redox agent. showed an auxin-like activity thus promoted root growth development. It positively affected soil’s physical, chemical, biological properties. Hence, indirectly improved plant by chelating nutrients to the plant. However, converted carcinogen compounds in chlorinat...

In the present work, CuInS2 nanoparticles have been successfully synthesized by water-bath method with deionized water as solvent and thioglycolic acid as complexing agent at 80°C. The phase transition of CuInS2 from chalcopyrite to wurtzite was realized by adjusting the pH value of reaction solution. The emergence of Cu2S in the condition of higher pH value of reaction solution led to the form...

Instabilities in propagating fronts of the iodate-arsenous acid reaction are predicted by an empirical rate-law model. The planar front loses stability when the ratio of the reactant diffusivity to the autocatalyst diffusivity exceeds a critical value. The relative diffusivities can be altered by introducing a reagent that reacts specifically with the autocatalyst to form an immobile complex. E...
