Efficient Photocatalytic Removal of Toluene by Synergistic FeCe/TiO2: Performance and Mechanism
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Efficient removal of volatile organic compounds (VOCs) in confined spaces is crucial for environments such as spacecraft and deep‐sea submarines. Metal modification is an effective strategy to enhance the light absorption capacity of titanium dioxide (TiO2) and suppress the recombination of photogenerated charge carriers.

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT The commercialization of lithium–sulfur batteries (Li–S batteries) has been hindered by the shuttle effect of lithium polysulfides (LiPSs) and sluggish redox kinetics. In this study, we constructed a three‐dimensional hollow conductive network host material for sulfur with synergistic enhancement effects.

四川大学学报. 自然科学版, 1988 原子核在俘获一个中子以后,形成复核并处于激发态,在很短的时间内发射出级联γ射线而退激。很多激发态的寿命的特征时间～10-13秒.这一特征时间与MeV能量复核的慢化时间在同一数量级内,因而复核的衰变就会影响复核的运动,即处于不同慢化阶段的运动复核其发射的γ射线的Doppler位移将不同.这就是复核γ谱的Doppler展宽.Doppler展宽的γ谱形与复核的衰变常数有关,因而复核γ谱实际上记录了激发态的衰变特性.利用这一事实便可从复核γ谱上获得复合核寿命的资料.然而目前这一方法只能对寿命的数量级进行估计 ...

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Ultrathin, lightweight, and mechanically compliant electromagnetic interference (EMI) shields are increasingly required for high‐frequency electronic devices. However, conventional metallic shields predominantly rely on conductivity‐driven reflection mechanisms, which become ineffective at reduced thickness and may cause severe secondary ...

Flexible, Robust Transparent Conductive Films With Excellent Electromagnetic Shielding Properties
Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Transparent conductive films (TCFs) are indispensable components for next‐generation wearable electronics, intelligent robots, and electromagnetic interference (EMI) shielding devices. However, the fabrication of conventional random metallic mesh suffers from an inherent trade‐off between “randomness and controllability”.

Huli yanjiu, 1993 肾病综合症（简称NS）是儿科泌尿系统中较常见的疾病,其发病占第二位.近40年来,糖皮质激素一直是治疗小儿肾病综合症首选药物,多数患儿需长期服药治疗,临床上复发者较多.经过对20例小儿肾病综合症长期治疗的家庭护理调查,认为复发的原因除单纯激素治疗因素外,还与患儿家庭治疗、生活管理及家长对该病知识的了解程度有密切关系.提示了加强患儿院外治疗护理是维持住院疗效,促进患儿早日康复,防止复发的重要措施。 1 调查资料 我们对1990年以来经住院治疗临床症状缓解而出院后继续院外巩固治疗的20名患儿进行了随访调查.

Rare 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

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Gradient structures (GS) introduced by plastic deformation have been shown to effectively enhance the surface properties of metallic materials. However, the GS fabricated by existing methods often suffers from limited hardening depth and limited control over the GS layer, which constrain their engineering applications.
