New TiO2-based hybrid materials composed of an organic polymer, cellulose acetate butyrate and copolymer of acrylonitrile acrylamide (AN + AA) were prepared. The effectiveness of immobilization of microbial strain Arthrobacter oxydans 1388 on the newly synthesized hybrid membranes was investigated by biochemical methods. The obtained results revealed that the matrix more suitable for biofilm fo...

Neurotransmitter/sodium symporters (NSSs) are responsible for Na+-dependent reuptake of neurotransmitters and represent key targets for antidepressants and psychostimulants. LeuT, a prokaryotic NSS protein, constitutes a primary structural model for these transporters. Here we show that K+ inhibits Na+-dependent binding of substrate to LeuT, promotes an outward-closed/inward-facing conformation...

Investigations of ligand-binding kinetics to membrane proteins are hampered by their poor stability and low expression levels, which often translates into sensitivity-related limitations impaired by low signal-to-noise ratios. Inspired by affinity capturing of water-soluble proteins, which utilizes water as the mobile phase, we demonstrate affinity capturing and local enrichment of membrane pro...

An alumina-supported nickel catalyst was prepared by impregnation of Ni2+ solution onto mesoporous alumina under microwave irradiation (denoted as M-Ni/Al2O3). For comparison, a catalyst with the same nickel content was prepared by conventional impregnation method (denoted as UM-Ni/Al2O3). Both M-Ni/Al2O3 and UM-Ni/Al2O3 catalysts were applied to the syngas (H2 + CO) production by methane oxy-s...

Metal ion adsorbents are indispensable materials for the recovery of noble metal ions in a sustainable society. Herein, we report that poly(isopyrazole-3,5-diyl-trans-vinylene) (1) effectively adsorbed group 10 from solution acetonitrile. Owing to its fully π-conjugated and rigid structure, polyimine 1 was virtually insoluble common organic solvents water, making it advantageous adsorption via ...

The effectiveness of tetraethylammonium (TEA) and high-frequency stimulation (HFS) in inducing long-term synaptic modification is compared in CA1 and dentate gyrus (DG) in vitro. High-frequency stimulation induces long-term potentiation (LTP) at synapses of both perforant path-DG granule cell and Schaffer collateralCA1 pyramidal cell pathways. By contrast, TEA (25 mM) induces long-term depressi...

The production of biosorbents by waste biomass has attracted considerable attention due to the low cost and abundance raw materials. Here biochar produced from Eucalyptus camdulensis sawdust (EU-biochar) via pyrolysis at 600 °C was used as a potential biosorbent for Ni2+ Pb2+ metal ions wastewater. Characterization experiments indicated formation C- O-bearing functional groups on EU-biochar sur...

Magnetic behavior and disproportionation effect of nickelates are closely related to the nature their ground state. In present work, magnetic structure, lattice dynamics, electronic properties, yttrium nickelate (YNiO3) in its state P21/n structure were investigated by first-principles phonon calculations based on density functional theory (DFT). The strong correlated interactions treated DFT +...
