Facile synthesis of ZnO-SnO2 anchored ZIF-8 nanocomposite: a potential photocatalystSpringer Science and Business Media LLC - Tập 27 - Trang 25103-25118 - 2020
Ramesh Chandra, Mala Nath
For the first time, ZnO-SnO2 nanocomposite has been anchored (ZS@Z) on ZIF-8 (zeolitic imidazolate framework) surface and encapsulated (ZS@Z1, ZS@Z2 and ZS@Z3) within ZIF-8 matrix during the in situ synthesis of ZIF-8. ZnO-SnO2 nanocomposites were synthesized in various molar ratio of Zn and Sn, i.e. 1:1, 2:8, 4:6, 6:4 and 8:2 (abbreviated as ZS-11, ZS-28, ZS-46, ZS-64 and ZS-82) using sol-gel and...... hiện toàn bộ
Monitoring OH-PCBs in PCB transport worker’s urine as a non-invasive exposure assessment toolSpringer Science and Business Media LLC - Tập 25 - Trang 16446-16454 - 2018

In this study, we analyzed hydroxylated polychlorinated biphenyls (OH-PCBs) in urine of both PCB transport workers and PCB researchers. A method to monitor OH-PCB in urine was developed. Urine was solid-phase extracted with 0.1% ammonia/ methanol (v/v) and glucuronic acid/sulfate conjugates and then decomposed using β-glucuronidase/arylsulfatase. After alkaline digestion/derivatization, the concen...... hiện toàn bộ
Graphene oxide dispersed mesoporous ZIF-8-encapsulated laccase for removal of toluidine blue with multiple enhanced stabilitySpringer Science and Business Media LLC - - 2023
Fang Yuan, Shengran Jia, Dingfan Yan, Xiaokuan Zhang, Jinbo Zhang, Ting Xia
The extensive use and discharge of toluidine blue have caused serious problems to the water environment. As a green biocatalyst, laccase has the ability to decolorize the dyes, but it is limited by poor reusability and low stability. Metal–organic frameworks (MOFs) are a good platform for enzyme immobilization. However, due to the weak dispersion of MOFs, the enzyme activity is inevitably inhibite...... hiện toàn bộ
How does renewable energy, newborn birth rates, industrialization, and economic growth affect environmental quality? New evidence from 90 Belt and Road countriesSpringer Science and Business Media LLC - Tập 30 - Trang 104148-104168 - 2023
Jikun Jiang, Shuning Gao, Wenyu Yuan, Weihao Wang, Bilal Aslam
Reducing carbon emissions is a critical approach for attaining global environmental sustainability and combating climate change. To investigate how energy, population, industry, and economic structure affect environmental quality. This study collects panel data for 90 Belt and Road (B&R) nations from 1995 to 2021. For the first time, the nonlinear dynamic impacts of renewable energy, newborn birth...... hiện toàn bộ
