Gongye shui chuli, 2023 漆酶（LAC）能够有效催化氧化废水中多种难降解的有机污染物，但其游离态不够稳定，且难以回收再利用。采用动态晶化法合成了一种由MWW结构纳米片交错共生而成的分级孔空心分子筛微球（HZM），并将其用于LAC的固定化。结果表明，通过戊二醛（GA）交联法可将LAC固定于氨基功能化的HZM上，固载量可达198.6 mg/g，酶活性回收率约为52.4%；与游离态LAC相比，固定化LAC对酸度和温度敏感性降低，储藏和操作稳定性有明显提升；固定化酶循环使用8次后，仍可保留初始活性的50%以上 ...

Gongye shui chuli, 2022 为回收利用废水中的Cu2+，通过酸处理和化学改性法制备了新型纤维状海泡石吸附剂。分别考察了酸处理、十六烷基三甲氧基硅烷（HDTMS）改性对天然海泡石（Sep）表面性质的影响，并用制备的海泡石吸附剂（H-T-Sep）对水中的Cu2+进行吸附。对改性吸附剂的理化性质进行表征分析，HDTMS能在保持Sep原始晶体结构的情况下对其进行疏水化改性。静态吸附实验结果表明：H-T-Sep对水中Cu2+的吸附过程符合准二级反应动力学模型及Langmuir吸附方程，表明该吸附过程由多种行为控制。H-T ...

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 ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT This study introduces a novel velocity‐iterative directional annealing (IDA) strategy to overcome stagnation challenges in columnar grain growth of Ti‐48Al‐2Cr‐2Nb alloys. By dynamically adjusting hot zone migration rates across iterative cycles, the IDA protocol achieved 92.2% synchronization between anisotropic α‐grain boundary (GB ...
