Iridium 'loses its identity' when interfaced with nickel（图）
Iridium loses identity interfaced nickel
2019/10/17
Note to physicists and materials scientists: You'd better reevaluate your work if you study iridium-based materials -- members of the platinum family -- when they are ultra-thin.Iridium "loses its ide...
Researchers Inadvertently Boost Surface Area of Nickel Nanoparticles for Catalysis（图）
Researchers Boost Surface Area Nickel Nanoparticles Catalysis
2017/12/18
Ni nanoparticles (NPs) catalyze many chemical reactions, in which they can become contaminated or agglomerate, resulting in poorer performance. We report deposition of silica (SiO2) onto Ni NPs from t...
Nickel limitation of nitrogen fixation inTrichodesmium
Nickel limitation nitrogen fixation Trichodesmium
2014/4/2
I show that the growth ofTrichodesmium, the primary diazotrophic phytoplankton in tropical and subtropical oceans, can be limited by Ni availability in both trace metal–defined culture media and natur...

atomic data atomic processes line formation X-rays
2011/8/17
Abstract: We present R-matrix calculations of photoabsorption and photoionization cross sections across the K edge of the Li-like to Ca-like ions stages of Ni. Level-resolved, Breit-Pauli calculations...
Monte Carlo simulations of the Nickel K$\alpha$ fluorescent emission line in a toroidal geometry
galaxies active - line formation - radiation mechanism general - scattering - X-rays general
2010/11/12
We present new results from Monte Carlo calculations of the flux and equivalent width(EW) of the Ni K fluorescent emission line in the toroidal X-ray reprocessor model of Murphy & Yaqoob (2009, MNRAS...
Solid phase extraction of copper, nickel, and cobalt in water samples after extraction using surfactant coated alumina modified with indane-1,2,3-trione 1,2-dioxime and determination by flame atomic absorption spectrometry
Solid phase extraction surfactant coated alumina atomic absorption spectrometry
2010/12/3
A simple method for simultaneous pre-concentration of Cu, Ni, and Co metal ions prior to their determination by flame atomic absorption spectrometry is reported. The method is based on the extraction ...

The quotas of P, S, Mn, Fe, Ni, and Zn in individual Synechococcus cells collected from the surface and deep
chlorophyll maximum (DCM) layer of three mesoscale eddies in the Sargasso Sea were measure...
Effect of Additives on Catalytic Cracking of Biomass Gasification Tar over a Nickel-Based Catalyst
biomass gasification tar supported catalyst palygorskite nickel additive carbon deposition tar removal
2011/11/14
The palygorskite-supported nickel (Ni/PG) catalysts were modified by loading with several additives (Fe, Mg, Mn, and Ce) by
incipient wetness impregnation. The effect of the additives and their conte...
