The new compounds Ni2(tren)3(Mo202Sö)2 • 2.75 H2O (I) and Co2(tren)3(MoS4)2 (II) (tren = tris(2-aminoethyl)amine) were prepared under solvothermal conditions. The structure of I is built up of one-dimensional [Ni2(tren)3]4+ chains and isolated [M02O2S6]2anions. Each Ni atom in the cationic chain is surrounded by six N-atoms to form a distorted octahedron. The connection of the Ni-atoms in the [...

Most marine bacteria can produce exopolysaccharides (EPS). However, very few structures of EPS produced by marine bacteria have been determined. The characterization of EPS structure is important for the elucidation of their biological functions and ecological roles. In this study, the structure of EPS produced by a marine bacterium, Alteromonas sp. JL2810, was characterized, and the biosorptio...

Light alkene oligomerization on heterogeneous acidic catalysts is widely and successfully used in current commercial processes. However, ethylene remains inefficient due to ethylene’s inability form reaction intermediates a sufficient extent acid sites. Adding Ni(II) solid acids can more efficiently catalyze selectively produce butenes fuel range products. The review proposes complete detailed ...

Sensory transduction in olfactory receptors and photoreceptors is mediated by cyclic nucleotide-activated ion channels. We have studied the gating mechanism in olfactory and rod channels expressed in Xenopus oocytes. We report that the differences in cyclic nucleotide affinity and efficacy between these channels resulted from sequence differences outside the cyclic nucleotide-binding domain, es...

Mesoporous nanosized titania films modified with Co2+, Ni2+, Mn3+, and Cu2+ ions have been produced by templated sol-gel method and characterized by optical spectroscopy, X-ray diffraction (XRD), and Brunauer, Emmett, and Teller (BET) surface area measurement. Band gap energy and the position of flat band potentials were estimated by photoelectrochemical measurements. The films doped with trans...

Action potentials in pyramidal neurons are typically followed by an afterdepolarization (ADP), which in many cells contributes to intrinsic burst firing. Despite the ubiquity of this common excitable property, the responsible ion channels have not been identified. Using current-clamp recordings in hippocampal slices, we find that the ADP in CA1 pyramidal neurons is mediated by an Ni2+-sensitive...

Cellular progression to malignancy appears to require a number of distinct steps in which genetic damage in key regulatory genes accumulates. Immortalization, or escape from senescence, is considered to be one of the first phenotypic changes. Ni2+ treatment of normal human kidney epithelial (NHKE) cells in vitro resulted in immortalization of the cells IHKE cells). The combined action of Ni2+ a...

A series of ligands that contain both N-donor and N-oxide donor atoms have been synthesised and ligands L5, L6, L7 and L8 contain, 4, 6, 5, and 6 donor atoms respectively. The smallest ligand L5 forms a mononuclear complex with Cu2+ ([Cu(L5)(ClO4)2(MeCN)]) whereas L6 and L7 form dinuclear double helicates with Ni2+ and Cu2+ respectively ([Ni2(L6)2]4+ and [Cu2(L7)2]4+). L8 forms a tetranuclear c...

To improve the activities of non-noble metal catalysts is highly desirable and valuable to the reduced use of noble metal resources. In this work, the supported nickel (Ni) and nickel-platinum (NiPt) nanocatalysts were derived from a layered double hydroxide/carbon composite precursor. The catalysts were characterized and the role of Pt was analysed using X-ray diffraction (XRD), high-resolutio...

Supported nano zero-valent iron is receiving great attention nowadays due to its effectiveness in treating heavy metal pollutants. Therefore, this study aimed investigate the of granitic residual soil-supported (Gr-nZVI) for removal metals Pb2+, Cu2+, Co2+, Cd2+ Ni2+ and Zn2+ mixture solutions under different experimental conditions batch equilibrium tests. In study, Gr-nZVI was successfully sy...
