Resource Substitution: Local Governments' Issue Attention and Policy Reinvention
Policy Studies Journal, EarlyView.ABSTRACT Research on policy reinvention, where a government modifies rather than replicates policy innovations introduced by other governments, has progressed significantly, but how it is influenced by the government's issue attention has not been thoroughly examined.

Higher Education Quarterly, Volume 80, Issue 3, July 2026.ABSTRACT Amid intensified global talent competition and domestic demographic pressures, China, Japan and South Korea (hereafter, ‘Korea’) have expanded their international student policies beyond attraction and recruitment to include stronger measures for post‐study employment and retention, repositioning international students as strategic populations

The underappreciated roles of fog and dew on vegetation and biocrusts
New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Atom Probe Tomography‐Based Analysis of Residual Trace Elements in Advanced Metallic Materials
Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Residual trace elements inherited from raw materials strongly influence the mechanical and environmental performance of advanced metallic alloys and recycling materials due to preferable boundary/interface segregation and resultant embrittlement effects, yet their parts per million level concentrations pose significant challenges to ...

Gongye shui chuli, 2014 采用溶剂多级逆流法再生吸附饱和的粉末活性炭，筛选出最佳再生剂，优化了再生条件，并分析了溶剂逆流再生的影响因素。结果表明，有机再生剂的再生效果均优于无机再生剂，并以甲醇的再生效果最佳，甲醇的最佳再生时间为30 min，在较低的再生固液比下，PAC的再生率可达75%；在相同再生固液比下，甲醇二级逆流再生的效果高于一级再生，且PAC的再生率随再生次数的增大而逐渐降低，随再生温度的升高而逐渐增大。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT To overcome the strength–ductility trade‐off in fabricated Ti‐2Al‐2.5Zr alloy tubes, we systematically investigated the microstructural evolution and mechanical behavior throughout thermomechanical processing, including hot working (forging and extrusion) and cold multi‐pass rolling.

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Bone restoration is often hindered by the spatiotemporal dysregulation of immune and regenerative signals. Conventional bio‐inert implants, providing only passive support, fail to modulate this microenvironment, leading to infections and poor healing.

Gongye shui chuli, 1992 软化器是工厂企业主要耗水设备之一,为了做好软化器的节水工作,建议采取下述几项措施。1 将软化器顺流再生改为逆流再生有许多工厂企业目前使用的仍是顺流运行顺流再生软化器。如果将现有的顺流再生软化器改为逆流再生,可以节约软化器再生时的耗水量。软化器改为逆流再生后,可以免去大反洗过程,而以加再生液代替反洗。由于逆流再生的再生剂利用率高,废液量小,浓度低,正洗时间缩短,再生耗水量比顺流再生时可降低50%。直径1米的软化器再生一次可节水30米3。加之由于逆流再生工作周期延长。再生次数减少,节水量相当可观。

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The poor soft tissue integration around titanium implants creates a microgap that serves as a pathway for pathogen invasion, resulting in infection, inflammation, and the progression of peri‐implantitis. As the implant’s transmucosal component, the abutment determines the degree of peri‐implant soft tissue attachment.
