The new tantalum(II) complex (eta (6)-C 7H 8)TaCl 2(PMe 3) 2 ( 1) was synthesized by the reduction of TaCl 5 with n-butyllithium in the presence of PMe 3 and cycloheptatriene. Compound 1 adopts a four-legged piano stool structure in which the tantalum center is bound to a eta (6)-cycloheptatriene ring in addition to two chlorides and two phosphine ligands in a transoid arrangement. Treatment of...

This paper summarizes the main areas of research within TA Weinberg, namely an investigation into code review ability and personality; an investigation into code comprehension and personality; and an investigation into the results from an online programming competition and personality. With regard to code review, it was discovered that there is a relationship between code review ability and per...

Grain refinement plays a central role in powder bed fusion (PBF) additive manufacturing by preventing hot cracking and thus enabling the development of high-strength alloys. However, mechanism behind grain is not fully understood for conventional casting, nor PBF. In this work, high throughput method have been used to produce Al-2 wt%Cu alloys with additions Ti1-xM(Zr,Ta,V,W)xB2, Al3Ti1-xM(Zr,V...

Due to the low neutron activity, high thermal stability, and good compression strength at elevated temperatures, medium-entropy Ta-Ti-V alloys have application potential be used in future nuclear engineering. According experimental results, a special quasi-random structure (SQS) model first-principles calculations are calculate structural stability elasticity of ternary single-phase body-center...
