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

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

Recovering Critical Elements From Wastewater for Battery Materials: A Review

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Driven by global carbon neutrality goals, the transition toward a circular economy and sustainable resource management has become increasingly imperative. Given the indispensable role of battery technologies in modern energy storage systems, strategic elements such as lithium (Li), cobalt (Co), and nickel (Ni)—identified by the European ...

Preparation of Highly Bioactive Nanolignin via Dopamine Mannich Modification and Its Synergistic Effects With Zn2+ in PVA Hydrogels

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Lignin is a natural non‐toxic polyphenolic macromolecule, which shows inherent antioxidant and broad‐spectrum antibacterial activities. However, due to the low content and the high bond dissociation energy of phenolic hydroxyl groups (Ar‐O·H), its antioxidant and antibacterial activities are relatively weak, which limits its application as a ...

Multi‐Site Chelation Enabled by 3D‐Printed TiO2 Hydrogel Monoliths for Dynamic Ge(IV) Recovery in Fixed Beds

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 ...

金沙江流域不同牧草生长特性分析

Shuitu Baochi Xuebao, 2006
为了促进金沙江干热河谷区草业开发、畜牧业基地建设和生态农业发展，筛选出再生性强、产量水平高、水分利用效率高的人工牧草，我们于2005年研究了4个不同牧草的再生草产量、再生草生长速度以及再生草水分利用效率。结果表明，所有引进种二茬草的再生速度都比当地轮生狗尾草高。所有引进种再生草的产量都高于当地轮生狗尾草。斯伦春大翼豆、德梅纳罗克非洲狗尾草、贝斯莉斯克伏生臂形草等牧草再生草产量高，水分利用效率高，再生性强，是适于在金沙江干热河谷地区推广种植的节水型牧草。

Targeting Inflammaging: A Metformin‐Releasing Titanium Implant Reprograms Senescent Macrophages to Orchestrate Angiogenesis and Osteogenesis

Rare Metals, Volume 45, Issue 7, July 2026.
ABSTRACT Bone defect repair in elderly patients is frequently compromised by reduced osteogenic capacity and delayed healing. Chronic inflammation‐driven inflammaging is a critical contributor to this impairment, characterized by dysfunctional autophagy in senescent macrophages (S‐MΦs), excessive reactive oxygen species (ROS) accumulation, and ...

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 ...

建筑回填土中再生水灌溉对草坪草生长及土壤理化性质的影响

Shuitu Baochi Xuebao, 2016
为探明建筑回填土条件下草坪草种植的适宜性以及再生水灌溉对草坪草生长和土壤理化性质的影响情况，选用黑麦草为试验对象，通过室内盆栽试验的方式，设置清水灌溉、再生水灌溉、清水—再生水交替灌溉3个处理，研究了呼和浩特市建筑回填土灌溉再生水对草坪草生长及土壤理化性质的影响。试验发现：(1)与清水灌溉相比，清水—再生水交替灌溉、再生水灌溉下的草坪草生长速率分别增长了23%，34%。(2)各处理草坪草在质地、盖度、均一性方面的得分表现为再生水灌溉＞清水—再生水交替灌溉＞清水灌溉，但差异性不显著（P＞0.05）。(3 ...

3D Printed High‐Strength Hydrogel for Dual Release of Cu2+ and Ag+ Ions to Enhance Bone Repair and Antibacterial Properties

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.

Upcycling of Waste Polyethylene Terephthalate Plastics to Fabricate Cobalt–Nickel Metal–Organic Frameworks and Their Phosphides for Efficient Oxygen Evolution Reaction

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT The urgent environmental crisis caused by polyethylene terephthalate (PET) waste necessitates efficient upcycling strategies. Herein, we establish a novel pathway to transform waste PET plastic into a high‐performance catalytic material for mediating the oxygen evolution reaction (OER). Through a one‐step hydrothermal process, waste PET serves
