High-entropy alloys (HEAs) are new alloys that contain five or more elements in roughly-equal proportion. We present new experiments and theory on the deformation behavior of HEAs under slow stretching (straining), and observe differences, compared to conventional alloys with fewer elements. For ...
High-entropy ceramics is an emerging, yet blooming class of materials owing to its ever-growing set of applications, such as thermal barrier protection, wear- and corrosion-resistant coatings, thermoelectrics, batteries and catalysts1,2. They stand out for their mechanical properties, thermal and ch...
Here, we proposeplasmonic transition-metalhigh-entropycarbides (PHECs) as a class of multifunctional materials able to couple thermal stability, mechanical resistance, and plasmonic properties in the near-IR and visible range. Indeed, they gather the good plasmonic properties of TaC, the superior mec...
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...
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...
and the speed of recovery. These crash-recovery measures are typically applied to financial returns (refer to D’Amico et al. (2020), D’Amico et al. (2023) for examples). However, applying them to trading volumes alters their financial interpretation. Specifically, when volumes are low, the...
(individual interest, self-efficacy, and self-regulation) as indicator variables for learner characteristic profiles. We tested models between one and five profiles. The best-fitting latent profile model was determined by examining relevant fit indices (AIC, BIC, adjusted BIC, Entropy, and LRT and...
Taking the cities along the Yellow River Basin (YRB) as research objects, the entropy-TOPSIS model is used to evaluate urban ecological level; and the main obstacle factors that restrict the improvement of urban ecological level are analyzed through the obstacle diagnosis model. The results show ...
High-entropy multimetallic nanopatterns with controlled morphology, composition and uniformity hold great potential for developing nanoelectronics, nanophotonics and catalysis. Nevertheless, the lack of general methods for patterning multiple metals poses a limit. Here, we develop a DNA origami-based metalliz...
Existing data-driven approaches for exploring high-entropy alloys (HEAs) face three challenges: numerous element-combination candidates, designing appropriate descriptors, and limited and biased existing data. To overcome these issues, here we show the d
