Unlocking the Potential of Machine Learning for Advanced Single‐Atom Catalysts Design in Promoting Electrochemical CO2 Reduction

open access: yesRare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Electrocatalytic CO2 reduction reaction (CO2RR) represents a pivotal pathway for the promotion of carbon neutrality and the preparation of highly valuable chemicals. To improve the product selectivity and catalytic efficiency of CO2RR, single‐atom catalysts (SACs) offering highly efficient atomic utilization rates and adjustable electronic ...

铜蒸气浓度对SF6-Cu高温电弧物性参数的影响

open access: yesGaoya dianqi, 2016
开关设备(例如高压SF6断路器)触头表面产生的铜金属蒸气会改变电弧等离子体的物理化学特性。因此在建立考虑金属烧蚀的流体仿真模型之前,需要确定含有金属蒸气的电弧等离子体的性质。文中基于吉布斯自由能最小化原理和Chapman-Enskog理论,计算了SF6-Cu混合气体电弧在0.6 MPa压强下、温度区间为30030 000 K时的物性参数,包括平衡态粒子组分、统计热力学参数、输运系数和混合扩散系数,着重分析了铜蒸气浓度(最大90%)对上述物性参数的影响。结果表明少量的铜对物性参数无明显影响 ...

From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

In‐Situ Construction of Multi‐Scale Heterogeneous Structures in L‐DED IN718 Coatings via WMoTaNb Incorporation for Enhanced Strength‐Toughness Synergy

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To improve the strength–toughness balance of IN718, and alleviate the brittleness commonly associated with refractory high‐entropy alloys, this study proposes a novel strategy to fabricate defect‐free IN718/WMoTaNb heterogeneous multiprincipal element alloy coatings via laser‐directed energy deposition.

Laser‐Induced Graphene/AuNPs‐Gated OECT Biosensor for Sensitive Detection of PD‐L1‐Positive Exosomes Associated With Non‐Small Cell Lung Cancer

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Lung cancer remains a major cause of cancer‐related mortality worldwide, and non‐small cell lung cancer (NSCLC) accounts for the largest proportion of diagnosed lung cancer cases. Exosomal programmed death‐ligand 1 (PD‐L1) has attracted increasing attention as a potential liquid‐biopsy biomarker associated with tumor immune regulation; however,

Determinants of preterm pre‐eclampsia following low‐dose aspirin prophylaxis: evidence from stepped‐wedge cluster randomized trial in Asia

open access: yesUltrasound in Obstetrics &Gynecology, Volume 68, Issue 4, Page 492-503, October 2026.
ABSTRACT Objectives To identify potential risk factors – among maternal factors, pre‐eclampsia (PE)‐specific biomarkers and estimated risks derived from the first‐trimester Fetal Medicine Foundation (FMF) triple test – that are associated with the subsequent development of preterm PE, and to evaluate predictors of any‐onset PE using time‐to‐event ...

Spatiotemporal Pattern Evolution and Driving Mechanisms of World Botanical Gardens Over Five Centuries

open access: yesIntegrative Conservation, Volume 5, Issue 3, Page 255-267, September 2026.
This study presents a comprehensive review of the 500‐year spatiotemporal evolution of global botanical gardens, identifying three major development stages—initial exploration (1543–1699), steady expansion (1700–1899), and rapid proliferation (1900–2020)—with six distinct sub‐stages. We propose a tripartite driving framework grounded in colonial botany
