Structure and properties of the new phase of the pseudo one-dimensional compound TaS 3 The structure of a new form of tantalum trisulfide has been determined from single crystal X-ray diffraction data and refined to an R value of 0.025. The u... A Meerschaut,L Guemas,J Rouxel - 《Journ...
Much larger c-axis lattice parameter implies that atomic bonding in the out-of-plane direction is relatively weak. Table 1 illustrates that Both TaX and NbX WSMs have very similar structural characters. CaSn3 in the cubic phase, on the other hand, has much smaller cell volume and bulk ...
TANTALUMCAST-ironIRON foundingFIELD emission electron microscopyA study was undertaken to investigate the effects of small boron additions on the solidification and microstructure of hypo-eutectic alloyed grey cast iron. The characteristic temperatures upon crystallisation of the treated metal ...
A series of Co nanocluster-assembled films with cluster sizes ranging from 4.5 nm to 14.7 nm were prepared by the plasma-gas-condensation method. The size-dependent electrical transport properties were systematically investigated. Both of the longitudinal resistivity (ρxx) and saturated anomalous Hall...
Tantalum influence on physical properties of (K{sub 0.5}Na{sub 0.5})(Nb{sub 1-x}Ta{sub x})O{sub 3} ceramics Lead-free (K{sub 0.5}Na{sub 0.5})(Nb{sub 1-x}Ta{sub x})O{sub 3} ceramics with x = 0.00-0.30 were prepared by the solid-state reaction technique. The effect... ...
[29] the presence of a major cubic fluorite-type (F-type) phase accompanying by a weak rare earth cubic-type (C-type) superstructure has been observed from the XRD pattern of Sm2Ce2O7 depicted in Fig. 1, Fig. 2. It means that when the ionic radius ratio (Sm3+/Ce4+ = 0.109 nm...
The second aluminum foil (in case of tantalum condensers it may also be a porous layer of carbon powder) is in contact with this electrolyte, thus an electrochemical double layer is established. Its capacitance Cdl is so large that the actual and resulting value of the series connection is ...
The arc furnace was then flushed with Argon (5N) to atmospheric pressure, punned out a ^ i n and f i l l e d to the operating pressure of 200mm Hg, Before the actual melting of the conponents the furnace was gettered for one minute with molten tantalum. After the components were ...
of two BCS-type gaps appears to describe the zero-magnetic-field specific heat better than those based on the isotropic BCS theory or anisotropic functions. A positive curvature of the upper critical fieldHc2(Tc) and nonlinear field dependence of the Sommerfeld coefficient at 0.4 K ...
where 1D diffusive motion leads to a weak power law dependence for λ(BLF), and the method can be extended to systems of higher dimensionality29. Further details are given in theSupplementary Methods. Figure2bshows example data at 120 K, fitted against spinon diffusion models on 1D, 2D, ...
