The specific features revealed in the structure of the d3 Cr(III), d2 Cr(IV), d1Cr(V), and d0 Cr(VI) peroxo complexes with the ratios M:O2= 1:1, 1:2, and 1:4 are considered. It is noted that, in...V. S. Sergienko...
other around the Fermi energy, forming nodal lines in quantity at differentkzplanes of the Brillouin zone. The space group P6322 of the Fe1/3TaS2allows nonsymmorphic protected spin-polarized Weyl points in theΓ−Adirection. Since these Weyl points are far away from the Fermi level, they w...
The compound HC(SiMe 3 ) 2 (SiMe 2 C 5 H 4 N-2), 1 , reacts with methyllithium in THF to give a good yield of the lithium derivative which has been isolated as a molecular THF adduct 2 . This reacts (a) with KO t Bu to give 3 , which crystallizes in a solvent-free ioni...

Overall, at temperatures and concentrations relevant to engineering applications, the Labusch model is therefore expected to control the strengthening mechanisms for these alloys and for most dislocation core structures in metals. 展开 关键词: Theoretical or Mathematical/ ab initio calculations aluminium ...
Transition metal dichalcogenide is a family of thin semiconducting materials in the form of MX2 in which M represents the transition metals molybdenum (Mo), tungsten (W), vanadium (V), etc. and X represents chalcogen atoms sulfur (S), selenium (Se), tellurium (Te). The transition metal lay...
For example, NbS2, NbSe2, TaS2, and TaSe2 are metals in bulk form [9], [10], while ReS2, ReSe2, MoS2, MoSe2, WS2, WSe2, MoTe2, and WTe2 are semiconductors [11], [12], [13], [14], [15]. Among the various SL TMDCs, group-VIB ones (M=Mo, W; X=S, Se) have ...
New copper(II) complexes of the cyclic trinuclear type with 1,2,4-triazole ligands, [Cu(3)(mu(3)-OH)(aaat)(3)(H(2)O)(3)](NO(3))(2).H(2)O [Haaat = 3-acetylamino-5-amino-1,2,4-triazole] (1) and ([Cu(3)(mu(3)-OH)(aat)(3)(mu(3)-SO(4))].6H(2)... S...
Structural characteristics of peroxo complexes of transition metals of Groups IV and V (Ti, V, Nb, and Ta) with the ratios M : O 2 = 1: 1, 1: 2, 1: 3, and 1: 4 and alkyl peroxo complexes of Ti, Hf, and V have been considered. The structural manifestation of the trans ...
1). Based on the similarity in the various structures, a model simulating the deposition of TMDs can be derived from simulation models for metals, with two major modifications: (1) there are two types of elements in the stack, metal (M) and chalcogen (X), following the stacking sequence ...
