Nanocellulose‐Based Aerogels for Adsorption Applications in Environmental Remediation: State of Art, Challenges, and Future Outlook

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The escalating severity of global environmental pollution necessitates the development of sustainable and efficient adsorption materials. Nanocellulose (NC), sourced from the most abundant natural polymer on earth, has shown great potential in this field due to its renewability, biodegradability, and exceptional nanoscale properties.

A Strontium‐Based Polyphenol Nanozyme Reverses Cisplatin‐Related Acute Kidney Injury Through Near‐Infrared‐Enhanced PI3K/AKT Pathway Inhibition and Macrophage M2 Directional Polarization

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Cisplatin‐related acute kidney injury (CP‐AKI) is a serious complication of cisplatin (CP) treated patients with cancer with high morbidity and mortality rates. It is directly related to the abnormal accumulation of CP in renal tubular epithelial cells, causing metabolic toxicity, DNA damage, and oxidative stress.

1 100 kV B类接地开关三维电场数值计算与优化设计

open access: yesGaoya dianqi, 2019
接地开关的静电场仿真计算可以指导产品的结构优化,从而缩短产品研发周期降低产品研发费用。为了得到接地开关表面电场,以承德特高压串补用串1 100 kV B类接地开关为样本,计算接地开关分闸状态下表面电场分布。首先依据设计尺寸利用SolidWorks软件对接地开关进行实体建模;然后依据三维有限元数值计算法对接地开关典型时刻下的电场电位进行了三维有限元仿真计算,得出其电位及表面电场分布;仿真结果显示高场强出现在辅助回路均压环、静触头均压环及动触头表面;接着对接地开关高场强区域进行了优化设计 ...

An experimental approach to assess the combined effects of multiple stressors on a large vertebrate species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

Constructed value of information with iterative scoring and parametric uncertainty to identify management‐relevant research priorities for a declining raptor species

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Constructed value of information (CVoI) is an expert elicitation decision‐analytic tool used to prioritize sources of uncertainty based on their potential to improve decision outcomes if resolved. Despite increased application of CVoI, the robustness of CVoI prioritization of sources of uncertainty relative to differences in expert elicitation

Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate
