Degradation of tetracycline by visible light using Ca2Nb2O7 composite oxides with perovskite and pyrochlore sub-crystalline phases

CrystEngComm, 2024, Advance Article
DOI: 10.1039/D4CE00044G, Paper
Junwei Xu, Chengxin Lu, Xianfeng Zhang, Rumeng Ouyang, Xiuzhong Fang, Xianglan Xu, Xiang Wang
We synthesized two paramorphs of Ca2Nb2O7 for visible light degradation of tetracycline, and found that pyrochlore phase has better reactivity compared to perovskite phase, which is attributed to the intrinsic oxygen vacancies and lattice disorder of pyrochlore phase.

The Lab That Makes Lightning (Warning: Contains Flashing Lights)

The High Voltage Laboratory at the University of Manchester is one of the few places in the world that makes lightning. The lab works to predict failures on the electrical grid and protect it from blackouts. To do so, Dr Vidyadhar Peesapati and his team test electrical equipment to its limit - sometimes striking it with up to millions of volts. WIRED went inside the lab to learn more about the team's work, and see some lab-made lightning close-up.
