A low-density, nanocrystalline high-entropy alloy, Al20Li20Mg10Sc20Ti30 was produced by mechanical alloying. It formed a single-phase fcc structure during ball milling and transformed to single-phase hcp upon annealing. The alloy has an estimated strength-to-weight ratio that is significantly hig...
Multiple principal element or high-entropy materials have recently been studied in the two-dimensional (2D) materials phase space. These promising classes of materials combine the unique behavior of solid-solution and entropy-stabilized systems with high aspect ratios and atomically thin characteristics ...
不同地,LaserMix按照倾角ϕ进行划分的策略很好地适配了LiDAR点云的场景分布,从而为前文所述的半监督学习框架构建了较优的低熵区域(low-entropy areas),整体地提升了半监督条件下的LiDAR点云分割性能。 结论与讨论 这个工作提出了一个名为LaserMix的用于半监督LiDAR点云分割的框架。该工作不仅为所提出的框架提供有...
low concentration47. Electrocatalytic activity may be greatly amplified by tuning the stoichiometric ratios, as was reported for the record oxygen evolution activity of Fe0.25Ni0.75oxyhydroxide materials48. Because the high-entropy classification is predicated on the equimolar ratio of the elemental ...
Nowadays, high-entropy alloys (HEAs) have become a hot research topic in the field of coating materials. However, HEAs have a large wide range of compositional systems, and the differences in their composition inevitably lead to the significant variations in the matching process parameters of laser...
If stronger safety guarantees are needed, then a balanced tree should be used. Scapegoat and splay trees only offer amortized complexity guarantees, whereas treaps require an entropy source and have higher constant factors in practice. Self-balancing structures such as 2-3 or red-black trees requi...
we examine the hypothesis that different distributions exist asschanges on real risk measures. We do this by employing the goodness-of-fit test suggested in Song (2002). This test, which is grounded in relative entropy or Kullback–Leibler divergence (see Kullback and Leibler (1951)), ascertain...
The temperature dependency of the pressure was derived and utilized to calculate the enthalpy and entropy changes as function of temperature and pressure. The highest value of the internal pressure experienced by OLC was calculated to be about 7 GPa at the highest temperature. At 920.6 K, and ...

(Figs.S16–S20and TableS3), as shown in Supplementary note2. Considering the lowηand the small Tafel slope, the as-synthesized AuSA-MnFeCoNiCu LDH exhibits better OER activity than other AuSA-HE LDHs in this works (Fig.S18) and most reported high-entropy electrocatalysts (Fig.3d)19,20...
