ABSTRACT Multifunctional thermal protective ceramic thermal/environmental barrier coatings (T/EBCs) are of great significance for applications of various high‐temperature components, and we propose an effective strategy for designing high‐entropy ceramics (HECs) as T/EBCs for SiC ceramic matrix composites (CMCs), where low thermal expansion ...

ABSTRACT The immunosuppressive milieu of hepatocellular carcinoma (HCC) remains a major obstacle to durable antitumor responses. Mechanical‐energy‐driven piezocatalysis provides a noninvasive means of inducing oxidative damage and immunogenic tumor destruction; however, inefficient utilization of piezoinduced charges and insufficient localization of ...

低压预制母线用于10 kV柱上变压器的二次侧,是一体化改造的重要举措,而研究其温升特性具有重要意义。论文主要选取额定电流为630 A的低压预制母线作为研究对象,首先建立了其三维几何模型,采用电磁场—温度场以及电磁场—气流场—温度场耦合的多物理场模型,对其展开了仿真研究,并与型式试验结果进行了对比,验证了仿真结果的正确性。处于自然对流条件下的预制母线采用电磁场-温度场耦合模型,处于强制对流条件下的预制母线采用电磁场—气流场—温度场耦合模型。同时,文中仿真分析了不同负载情况下的预制母线温升分布情况 ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Insights Into the Temperature‐Dependent Oxidation Mechanism of Metallic Cerium in H2O‐N2 Atmospheres
ABSTRACT Metallic cerium (Ce), a widely used surrogate for actinide metals, enables mechanistic studies of reactions in complex gas environments under controlled and safer laboratory conditions. Here, the oxidation behavior of Ce in H2O‐N2 mixed atmospheres was investigated from 200°C to 350°C using in situ thermogravimetry–mass spectrometry, in situ X‐

ABSTRACT The limited crack resistance of coarse grain boundaries and coarse interfaces leads to an incompatibility between high‐temperature strength and ductility in TiAl alloys. Tailoring stress‐oriented textures and multiscale heterogeneous interfaces can effectively impede crack propagation, thereby overcoming this trade‐off.
