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 ...

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 ...

光还原法制备增强光催化性能的Bi-TiO₂纳米管

Gongye shui chuli, 2018
采用阳极氧化法及简易光沉积法制备了一种Bi-TiO2纳米管（Bi-TNAs）光催化剂，并对其形貌、晶相以及光吸收性能进行表征。结果显示，薄片状的金属相Bi微米片成功沉积在TiO2纳米管阵列表面。光催化降解罗丹明B实验显示，Bi-TNAs的光催化降解性能比TNAs显著增强。单质Bi微米片作为电子陷阱可捕获TiO2的光生电子，延长载流子寿命，降低电子-空穴复合速率，增强TNAs光催化降解罗丹明B的活性。
