Pentavalent vanadium and hexavalent uranium removal from groundwater by woodchip-sulfur based mixotrophic biotechnology

Huan Liu et al.

Summary: Mining and smelting of vanadium uranium ore leads to the release and coexistence of vanadium and uranium in the environment, posing severe risks. This study investigated the feasibility of synchronous removal of pentavalent vanadium (V(V)) and hexavalent uranium (U(VI)) using a mixotrophic column reactor packed with woodchips and elemental sulfur (S-0). The results showed that the removal efficiencies of U(VI) and V(VI) ranged from 55.1 to 80.7% and 52.2 to 99.5%, respectively. Several functional V(V) and U(VI) reducing microorganisms were identified, and they formed close partnerships. The study suggests that mixotrophic processes offer promising strategies for the simultaneous management of V(V) and U(VI) contaminated groundwater.

A High-Rate Electrode with Grotthuss Topochemistry for Membrane-Free Decoupled Acid Water Electrolysis

Shuaika Liang et al.

Summary: Water electrolysis powered by renewable energies is seen as a promising technology for hydrogen production, but traditional acid water electrolysis has limitations due to the coupling of H-2 and O-2 production and the need for a proton exchange membrane to prevent gas mixing. By introducing a low-cost redox mediator, decoupling the electrolysis process into two steps without a membrane, high-rate performance and long cycle life are achieved, enabling flexible high-purity hydrogen production using renewable energies.
