Surface strain tuning in a coupled heterostructure efficiently engineers the catalytic performance of heterogeneous catalysts by altering electronic structures and boosting electron transport. Generally, Bi-based are more favorable than ZnO for CO2 electroreduction to formate, but Bi is much costly Zn. Herein, new Bi2O2CO3/ZnO heterojunction catalyst with porous nanoplate morphology synthesized...

Biofilm is a significant cause for membrane fouling. Antibacterial-coated surfaces can inhibit biofilm formation by killing bacteria. In this study, polyethersulfone (PES) microfiltration membrane was photografted by four antibiotic quaternary ammonium compounds (QACs) separately, which were synthesized from dimethylaminoethyl methacrylate (DMAEMA) by quaternization with butyl bromide (BB), oct...

The interaction of a bovine serum albumin (BSA) protein with the mixture anionic sodium dodecyl sulfate (SDS) and cationic dodecyltrimethylammonium bromide (DTAB) has been investigated by small-angle neutron scattering (SANS) dynamic light (DLS).

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...

A novel neutrophilic metalloprotease was isolated from Pseudomonas sp. DR89 isolate which was identified ina mineral spring in Iran. The enzyme was purified from the isolate to 21-folds in a three-step procedure involving ammonium sulfate precipitation, Q-Sepharose ionic exchange and Sephadex G-100 gel filtrationchromatography. Resuts showed that the enzyme was active at high temper...

The delamination of montmorillonite in water leads to sliming in ore slurry, which is detrimental to mineral flotation and solid/water separation. In this work, the delamination of Na-montmorillonite (Na-MMT) has been restrained by sodium dodecyl sulfate (SDS) or octadecyl trimethyl ammonium chloride (1831) through the adsorption on the edge of the mineral. The experimental results have shown t...

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 endocytic protein dynamin II (dynII) participates in cell cycle progression and has roles in centrosome cohesion and cytokinesis. We have described a series of small-molecule inhibitors of dynamin [myristyl trimethyl ammonium bromides (MiTMAB)] that competitively interfere with the ability of dynamin to bind phospholipids and prevent receptor-mediated endocytosis. We now report that dynII f...
