Acoustically Assisted Heterojunction Hydrogel Promotes Angiogenesis and Tissue Regeneration by Modulating the Inflammatory Microenvironment

open access: yesRare Metals, Volume 45, Issue 8, August 2026.
ABSTRACT The healing of diabetic chronic wounds is hindered by multiple pathological barriers, including oxidative stress imbalance induced by hyperglycemia, persistent bacterial infection, and impaired neovascular function. This study developed an F127–HA–BiOCl@CeO2 (FHBC) hydrogel dressing with acoustic responsiveness, achieving tissue repair through

Collaboration in Cross‐Jurisdictional Water Quality Governance: A Novel Framework and Case Study

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Collaborative governance is often employed to address the inherent complexity of surface water quality governance and provides a structure for cooperation across federal, tribal, state, and local boundaries. However, although guidance exists for assessing specific dimensions of collaborative governance, tools to comprehensively evaluate the ...

计及静态安全约束的电-气耦合综合能源系统供电能力评估方法 [PDF]

open access: yes全球能源互联网, 2019
供电能力反映了电力系统所能承载的最大负荷,即在给定的发电机运行方式下,模拟系统中负荷的增长模式,不断检验系统的安全约束条件,从而确定系统所能供给的最大供电负荷。然而,随着以天然气为一次能源的燃气发电机发电比重的显著提升,传统供电能力评估方法并没有考虑燃气发电机的一次能源供应以及天然气系统的运行约束,显然并不恰当。为此,提出了基于连续多能流的电-气耦合综合能源系统供电能力评估方法。首先,建立了电-气耦合综合能源系统的多能流模型;接着引入负荷增长参数,提出连续多能流方法,通过预测-校正追踪多能流解曲线;最后,

Transfer Learning‐Guided Discovery of Advanced Tetrametallic Single‐Cluster Catalysts for Urea Electrosynthesis

open access: yesRare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Developing advanced electrocatalysts for urea synthesis is pivotal to alleviating environmental burdens as well as advancing sustainability in the industrial and agricultural sectors, yet untargeted catalyst screening still suffers from the notorious drawbacks of being time‐consuming, labor‐intensive, and inefficient.

Architecting a Robust Yarn‐Like CNT Framework for Structurally Resilient ZnSe Anodes in Potassium–Ion Batteries

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The development of structurally stable anodes with high capacities and long cycle lives is essential for the development of potassium–ion batteries. Conversion‐type anodes have attracted considerable attention in potassium–ion batteries (PIBs) due to their high theoretical capacities.

关于梅耶荷德“有机造型术”的两种文献 [PDF]

open access: yes, 2019
什么是"有机造型术",它包含哪些内容?要完整准确地回答这个问题不是那么容易的。陆续发掘出来的梅耶荷德遗产表明,他至少从1907年起就开始发表理论著作、出版杂志(例如《对三个橙子的爱》)、主持戏剧工作室,借此培养导演和演员、舞台美术师,在工作室里推行"舞台学"(сценоведение),参加论争,做报告,在自己的剧院内创建科研实验室,等等;说明他对戏剧理论是十分关注的。由于后来遭到残酷迫害,他的理论遗产一度失散或被封锁和销毁,未能得到应有的研究。另一方面 ...

垃圾渗滤液难降解有机物与氮同步去除影响因素

open access: yesGongye shui chuli, 2015
针对中老龄垃圾渗滤液中难降解有机物与高氨氮去除的难题, 提出了难降解有机物与硝酸盐氮的同步降解技术。通过试验考察了硝氮负荷、温度、pH及营养物质投加量等因素对系统去除效能的影响。结果表明, 硝氮负荷、进水pH、温度及营养物质投加量对系统处理效能的影响显著, 当pH为6.5~7.5, 温度为30 ℃, 硝氮负荷为0.08kg/(m3·d)时, 系统状况最佳。

A Wearable Colorimetric Sensor for Ultraviolet Monitoring via Radical‐Triggered Gold Nanoparticle Clustering

open access: yesRare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Reliable monitoring of ultraviolet (UV) radiation is critical for protecting human health, yet existing sensors often rely on costly or rigid components that hinder portability. Here we report a wearable, low‐cost colorimetric sensor for quantitative UV dosimetry, enabled by radical‐triggered aggregation of gold nanoparticles (AuNPs).
