ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.

ABSTRACT High‐power piezoelectric ceramics which have a wide operating temperature range are essential for sensor and actuator applications in extreme conditions. However, their development is fundamentally hindered by the inherent trade‐off among key parameters (TC, d33, Qm).

Eimeria saudiensis represents a genus of apicomplexan parasites capable of inducing coccidiosis in Arabian oryx. Our research concentrated on the morphological and molecular investigation of Eimeria spp. in the captive oryx herd in Oman. The therapeutic and management practices employed at the Mammals Breeding Center were reassessed to diminish ...

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 ...

ABSTRACT This article investigates how TikTok Shop reproduces the e‐commerce model of Douyin Shop against a backdrop of divergent regulatory challenges and geopolitical distrust. One of the strategic changes we observe in TikTok Shop is the shift of consumer goods suppliers from local merchants to China‐based sellers.

基于不同莫霍面模型的全波形理论地震图,计算了不同频率的接收函数,分析对比了不同形态莫霍面在不同频率上的接收函数变化特征。数值试验结果显示,当莫霍面的形态复杂时,高频接收函数上P−S转换波和多次波会出现多峰值特征。之后对不同形态莫霍面的模型在不同频率的接收函数进行了分类总结,据此判别实际观测资料所表征的莫霍面性质。以位于青藏高原东北缘的高台(GTA)地震台为例,分析了该台站不同频率的接收函数。结果表明,该台站下方莫霍面总体为遵循同一变化规律的速度过渡带,但在沿龙首山断裂方向附近速度变化不同于主要变化方式 ...
