This article reviews the application of transient techniques in the elucidation of electron, proton and photon chemistry related to the catalytic subsite of [FeFe]-hydrogenase from the perspective of research in this area carried out at the UEA and Strathclyde laboratories. The detection of mixed valence states, bridging CO intermediates, paramagnetic hydrides and coordinatively unsaturated spe...

We give plausibility arguments for the existence of a W–dressed electroweak string for the Weinberg–Salam model with θW = 0. This string is a Z–string which in the core has a finite energy contribution from W–condensation induced by the anomalous magnetic moment in the Yang–Mills field. The solution which has minimum energy at r = 0 interpolates between the unbroken (r = 0) and the broken (r → ...

introduction: raisin is a principal traditional export product of iran and has a special position in the foreign trade of the country.during storage, the product turns sticky and hard due to exudates syrup and moisture loss. to solve this problem, the application of edible coating would be an appropriatesolution. edible coating may enhance the boundary layer resistance resulting to the enhanced...

growing applications of phenylalanine dehydrogenase (phedh) enzyme in the medical and pharmaceutical industries encourages researchers to seek simple, fast and economical alternative purification methods. with goal of finding a new technique, the extraction and purification of recombinant bacillus badius phedh in polyethylene glycol 6000 (peg-6000) and ammonium sulfate aqueous two-phase systems...

In this study, the novel surface ion-imprinted polymer (IIP) particles were prepared and applied as a electrode modifier in stripping voltammetric detection of lead(II) ion. A carbon paste electrode (CPE) modified with IIP nanoparticles and multi-walled carbon nanotubes (MWCNTs) was used for accumulation of toxic lead ions. Various factors that govern on electrochemical signals including carbon...

A topical o/w cream containing tretinoin microspheres was prepared. Gelatin microspheres of tretinoin were prepared using coacervation method. These microspheres contained about 50% w/w tretinoin. The particle size range of microspheres was between 90-150 m m. In vitro drug release from microspheres and a cream formulation was studied. It was shown that drug release from microspheres followed H...

The materials of this study were collected from intertidal and shallow subtidal habitats of the Hengam Island coasts from May 2013 to May 2014. A total of 10 species representing eight genera and four families are reported as follows: Sphaeromopsis persikolpos Khalaji-Pirbalouty and Wägele 2009, S. sarii Khalaji-Pirbalouty and Wägele 2009, Sphaeroma khalijfarsi Khalaji-Pirbalouty and ...

in this research, modification on the ultrafiltration (uf) membrane by synthesis of a thin layer of polyamide selective layer was designed for high performances of forward osmosis (fo) water treatment. two monomers, m-phenylenediamine (mpd) and trimesoyl chloride (tmc) with different concentrations of mpd (2.0% w/v and 1.0% w/v) were reacted with tmc (0.15% w/v) for interfacial polymerization (...
