aIt is well known that iron has the highest magnetic moment among all 3d transition metals. The incorporation of iron into Si-based ceramics is desirable as it will introduce interesting magnetic properties. 它是知名的铁有最高的磁矩在所有3d过渡金属之中。 因为它将介绍兴趣的磁性,铁的并网到基于Si...
We select over 700 model molecules most of which model metalloprotein molecules that come from Protein Data Bank. We set reference charges for different apparent valence states of transition metals and calibrate the parameters of reference charges, valence state electronegativities, and valence state ...
The catalytic decomposition behavior ofenriched states of transition metalsin the peroxide bleaching system will be study focus in the near future. 指出纸浆H2O2漂白体系中各种富集态过渡金属元素的催化分解行为将成为今后H2O2漂白的研究方向。 2) Transition metal ...
The magnetic and electronic properties of both linear and zigzag atomic chains of all 3d transition metals have been calculated within density functional theory with the generalized gradient approximation. The underlying atomic structures were determined theoretically. It is found that all the zigzag chain...

OPTICAL properties of metalsRecently, lead halide perovskite nanocrystals (NCs) have gained tremendous attention in optoelectronic devices due to their excellent optical properties. However, the toxicity of lead limits their practical applications. Here, the synthesis of Zn-alloyed CsZnPbX(up to 15%)...

THE unique role that gold plays in society is to a large extent related to the fact that it is the most noble of all metals: it is the least reactive metal towards atoms or molecules at the interface with a gas or a liquid. The inertness of gold does not reflect a general inability ...
In this paper we present a new approach for the kinetic modelling of thermal transformations of solids. In the case of the corrosion of metals and alloys, the existence of a rate-limiting step is often assumed, which allows to account for the linear and parabolic kinetic curves (weight gain...
