Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Carbon dots (CDs) have emerged as promising modifiers for boosting the photocatalytic H2O2 production, yet their precise role remains to be quantitatively elucidated. Herein, S, N‐codoped lignin‐derived carbon dots (SN‐LCDs) and lignin‐derived carbon dots (LCDs) were synthesized and employed to modify TiO2.

Shuitu Baochi Xuebao, 2007 选取三峡水库消落区典型土壤,即紫色土、黄壤、紫色潮土和灰棕潮土为研究对象,以相应土壤胶体、蒙脱石矿物的10 mg/L Cd(NO3)2淋洗液分别淋洗土柱,研究了水分散态胶体对镉在土柱中迁移的影响.添加上述胶体的镉淋洗液,在紫色土、黄壤、紫色潮土和灰棕潮土土柱中镉迁移量分别是对照的1.18～4.96,1.05～2.37,1.10～4.33,1.03～3.33倍.结果表明胶体能够促进镉离子在土层中的迁移,其迁移能力遵循紫色土胶体≥紫色潮土胶体＞灰棕潮土胶体＞蒙脱石胶体＞黄壤胶体的规律.由此得出 ...

Preparation and Research of Electrospun PVDF Gel Polymer Electrolyte [PDF]
, 2016 凝胶态聚合物电解质是介于纯固态聚合物电解质和液态电解质的一种电解质，它既可以在常温下有较好的离子电导率，也可以一定程度地解决漏液、易燃、易爆等安全问题，因此受到了广泛关注。基于静电纺丝技术制备的聚合物纤维膜由于较高的孔隙率和较好的表面形貌，可以和有机电解液结合组成凝胶态聚合物电解质，表现出优异的电化学性能，在锂离子电池电解质领域有良好的发展前景。聚偏氟乙烯（PVDF）较高的介电常数和较低的玻璃化转变温度使它成为研究者制备聚合物电解质的常用材料之一。但是由于较高的结晶度和疏水性 ...
