High-entropy alloys (HEAs) are random solid solutions consisting of five or more elements arranged in an ordered crystal lattice. So far, however, nearly all the single-phase HEAs have either a cubic hexagonal structure. Here, we report observation single tetragonal sigma (σ) phase two series Ta5[Mo35–xW5+x]Re35Ru20 and [Ta5+yMo35–y]W5Re35Ru20 up to x = 30 y 8, respectively. Meanwhile, these discovered exhibit fully gapped bulk superconductivity with maximum Tc 6.29 K at 0. decreases...
We report the synthesis, crystal structure and physical properties of two new high-entropy silicides (HESs), namely (Nb$_{0.1}$Mo$_{0.3}$W$_{0.3}$Re$_{0.2}$Ru$_{0.1}$)$_{5}$Si$_{3}$ (Nb$_{0.2}$Mo$_{0.3}$W$_{0.3}$Re$_{0.1}$Ru$_{0.1}$)$_{5}$Si$_{3}$. Structural analysis indicates that both HESs consist a (nearly) single tetragonal W$_{5}$Si$_{3}$-type phase (space group $I$4/$mcm$) with disordered cation distribution. Electrical resistivity, magnetic susceptibility specific heat measurements...
Quantification of the isotopic composition uranium in urine at low levels concentration is important for assessing both military and civilian populations' exposures to uranium. However, until now there has been no convenient, precise method established rapid determination multiple isotope ratios. Here, authors report a new measure 234U/238U, 235U/238U 236U/238U. It uses solid-phase chelation extraction (via TRU columns) actinides from matrix, followed by measurement using magnetic sector...
Abstract In this paper, poly (lactic acid)/almond shell powder (PLA/ASP) composite filaments were prepared using the fused deposition modeling (FDM) method. The influence of chemical treatments on groups ASP was determined, and effects material ratios (3, 5, 10, 15 wt%) sliane concentration (2, 4, 6, 8 thermal mechanical properties composites investigated. optimal ratio in PLA/ASP observed at 10 wt% 4 silane. With processing parameters, Td0 (onset temperature) Td1 (the temperature maximum...
A new noncentrosymmetric superconductor, W 4 IrC 1− x , has been synthesized and characterized.
Chemical doping of topological materials may provide a possible route for realizing superconductivity. However, all such cases known so far are based on chalcogenides. Here we report the discovery superconductivity induced by Re in semimetal Mo5Si3 with tetragonal structure. Partial substitution Mo Mo5–xRexSi3 results an anisotropic shrinkage unit cell up to solubility limit approximately x = 2. Over wide range (0.5 ≤ 2), these silicides found be weakly coupled superconductors fully...
The effects of A-site cation size mismatch on La0.7 − xNdxCa0.3 y(Ba,Sr)yMnO3 perovskite materials with a constant average ionic radius ⟨rA⟩ = 1.2052 Å have been investigated. Polycrystalline samples prepared through the standard solid-state reaction method at high temperatures, and their structures, magnetic properties, magnetocaloric effect (MCE) investigated in detail. X-ray diffraction patterns show that all crystallized an orthorhombic structure space group Pnma. XPS analysis confirmed...
Abstract We report the effect of carbon doping in Ti‐stabilized nonstoichiometric molybdenum diboride B 2 , which exhibits bulk superconductivity below T c = 7.0 K. It is found that maintains AlB ‐type phase with a uniform elemental distribution for x 0.12 and 0.16. The substitution boron leads to slight increase ‐axis, remarkable reduction formation planar defects along (100) crystallographic planes, shift 1 s peaks toward higher binding energies. Contrary however, no observed down 1.8 K...
