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

Gongye shui chuli, 2016 从节能、防冻、优化操作等方面讲述独山子石化炼油厂对凝结水系统的回收改造，一方面将凝结水代替新水工质补入循环水场，降低了全厂新水的需求量；另一方面将凝结水并入热水系统，替换除氧水补水，同时对热量进行二次利用。通过对水汽系统联运联控摸索的不断调整，整合了全厂公用工程资源，达到了节能减排的目的。

Rare Metals, Volume 45, Issue 8, August 2026.ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT Germanium is a critical dispersed metal, yet sustainable recovery from dilute solutions is limited by sorbents that are difficult to regenerate and operate in continuous mode. Here, we fabricate a regenerable 3D‐printed hydrogel monolith (3D‐ATO‐GS) by integrating hydroxyl‐rich amorphous TiO2 nanoparticles into an alginate/gelatin scaffold ...

Gongye shui chuli, 2019 在实验室与现场环境下考察了超分子缓蚀剂CDDA对工业锅炉蒸汽凝结水中铁含量的抑制效应，并通过重量法、电化学与表面分析探讨了CDDA对碳钢的缓蚀机理。结果表明，CDDA可有效抑制蒸汽凝结水中的铁含量。现场监测显示，投加CDDA后，总铁质量浓度维持在60~70 μg/L，符合回水标准。CDDA以客体十八胺为有效缓蚀组分吸附于碳钢表面，并抑制阳极溶解过程，以减少腐蚀产物侵入凝结水，缓蚀率最高可达93.84%。处理后的凝结水与部分软化水混合后可用作锅炉补水，利于实现节能减排。

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.

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.
