the interactions of β-lactoglobulin ab in the presence of cationic surfactants such as cetyltrimethylammonium bromide and cetyltrimethylammonium p-toluenesulfonate have been investigated using a variety of experimental techniques such as conductivity, uv-vis spectrophotometry and fluorimetry. the conductivity of surfactants aqueous solutions with β-lactoglobulin shows that the cmc of cationic s...

A novel method utilizing non-aqueous capillary electrophoresis (NACE) with indirect ultraviolet detection (IUD) has been developed for the analysis of five quaternary ammonium compounds (QACs). The QACs analyzed in this study include dodecyl trimethyl bromide, tetradecyl dioctyl dimethyl chloride, octyldecyl chloride and didecyl dimethy bromide. separation process was carried out on an uncoated...

The viscoelastic properties of worm-like micelles formed by mixing the cationic surfactant N-hexadecyl-N-methylpiperidinium bromide (C16MDB) with the anionic surfactant sodium laurate (SL) in aqueous solutions were investigated using rheological measurements. The effects of sodium laurate and temperature on the worm-like micelles and the mechanism of the observed shear thinning phenomenon and p...

The title salt, C(4)H(10)Br(2)N(+)·Br(-), crystallizes with four cations and four anions in the asymmetric unit. In the crystal, the bis-(2-bromo-eth-yl)ammonium cations and bromide anions are linked into chains by N-H⋯Br hydrogen bonds describing a binary C(2) (1)(4) motif along [010]. Each of these chains is formed by a unique cation and anion pair. The ammonium cations occur in the less pref...

human serum albumin (hsa) is the most abundant plasma protein in the human body. hsa plays an important role in drug transport and metabolism. this protein has a high affinity to a very wide range of materials, including metals such as cu2+ and zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. in this study, we investigated the effects of co-amoxiclav, as...

We report a novel template method for synthesizing silica nanoparticles that are mesoporous as well biocompatible. The were synthesized using the Stober process and peptization method. have used surface-modified deoxyribonucleic acid (DNA) with cetyl trimethyl ammonium bromide capping agent. obtained particles analyzed x-ray diffraction, UV–vis spectroscopy, Brunauer–Emmet–Teller method, scanni...

The study presents a more efficient way of exfoliating MoS2 in water and the exfoliated was used an electrode. electrodes were prepared from (active material)–nanocrystalline cellulose (binder) with carbon nanotubes (electron-conducting support) demonstrated zinc battery half-cell that showed Coulombic efficiency 90%. Successful exfoliation done by sonication bulk sulfated nanocrystals (CNC) fo...
