Governing with health code: Standardising China's data network systems during COVID‐19
Abstract Noting the infrastructural turn in platform studies, the article conceives China's health code system, Jian Kang Ma (JKM), deployed to manage the COVID‐19 crisis as a new social infrastructure that manifests the symbolic and material power of the Party State.

通过模拟试验,考察了自然有机物的浓度、分子质量以及溶液的pH、温度对地下水混凝除铁的影响,并研究了预氧化在混凝除铁中的作用。结果表明,有机物的浓度越高、分子质量越大,有机铁的去除率越高。当Fe2+与分子质量>10 ku的有机物络合时,用混凝除铁能取得良好的效果;当Fe2+与分子质量<4 ku的有机物络合时,采用预氧化混凝工艺能达到较好的除铁效果。在pH6.0~7.5的范围内,降低pH有利于混凝除铁。温度升高对混凝除铁有利。

ABSTRACT Most high‐entropy alloys (HEAs) tailored for contaminant degradation suffer from complex fabrication processes and high‐cost alloy design. Furthermore, low‐cost active elements such as Fe and Mg cannot be readily alloyed into HEAs via conventional routes.

Investigating the Origin of Topological‐Hall‐Like Resistivity in Zn‐Doped Mn2Sb Ferrimagnet
ABSTRACT Skyrmions and other chiral spin textures have been extensively studied as potential building blocks for novel spintronic devices. Hall‐resistivity anomalies that deviate from magnetization scaling, known as the topological Hall effect, have been widely employed as evidence for the presence of chiral spin textures in magnetic materials. However,

High‐Value Targeted Conversion of Copper Slag as LiFePO4 Material for Lithium‐Ion Batteries
ABSTRACT The massive stockpiling of copper slag (CS) presents severe environmental and resource‐waste challenges. Existing strategies for CS valorization typically yield low‐value‐added products. Herein, we propose an innovative hierarchical regulation approach to transform CS into high‐performance LiFePO4 (LFP) cathode materials.
