Even though the sub-system analysis is computationally demanding and rigorous compared to the system perspective, it provides detailed insight within the quality of the thermal process and the exact location of features with high or low entropy generation rate. Altogether, the sub-system perspective ...

Here we develop room-temperature-solution (20 °C) and low-temperature-solution (80 °C) synthesis procedures for a new class of metal halide perovskite high-entropy semiconductor (HES) single crystals. Due to the soft, ionic lattice nature of metal halide perovskites, these HES single ...
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 ...

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...
When an atom jumps into a low-energy site, it gets “trapped” and the chance to jump out of that site becomes lower. In contrast, if the site is a high-energy site, then the atom has a higher probability to hop back to its original site. Either of these scenarios slows down the ...
Comparisons of functional properties between HEAs and conventional low-and medium-entropy materials are provided, and examples are illustrated using computational modeling and tuning the composition of existing functional materials through substitutional or interstitial mixing. Extending the concept of high ...
This enables fitness predictions using a simple decision rule, where if entropy is either above or below a threshold, fitness is respectively low or high. Importantly, this entropy-based method achieves better performance in predicting fitness outcomes compared to existing gene-panel approaches. In ...
Heuristic 1 Searching for subspaces with low entropy and high interest gain. For easy description, we call those subspaces with low entropy and high interest gain as interesting subspaces. Theoretically, we should search for outliers with high zk-values in subspaces. However, we are unable to sea...
