Transport Matters: The Critical Role of the Hydrogen Evolution Reaction (HER) in Accelerating Electrochemical Nitrate to Ammonia Conversion

Advanced Science, EarlyView.
A porous cobalt‐based metal‐oxide foam catalyst is synthesized using the DHBT technique, followed by calcination. It demonstrates exceptional activity for e‐NO3RR, reaching near‐unity ammonia selectivity at low overpotentials. Dynamic surface area changes due to NO3‐ depletion are mitigated by “self‐convection” during hydrogen evolution.

Potential Opportunities for Pharmacogenetic-Based Therapeutic Exploitation of Xanthine Dehydrogenase in Cardiovascular Disease

Antioxidants
The majority of naturally occurring mutations of the human gene XDH, are associated with reduced or completely absent xanthine oxidoreductase (XOR) activity, leading to a disease known as classical xanthinuria, which is due to the accumulation and ...

H2S Is a Potential Universal Reducing Agent for Prx6‐Type Peroxiredoxins

Advanced Science, EarlyView.
We report the identification of H2S as reducing agent for Prx6‐type peroxiredoxins. In contrast to common physiological reducing agents of other peroxiredoxins, HS− is small enough to access the active site of oxidized Prx6‐type enzymes in the fully‐folded protein conformation.

The nitric oxide response in plant-associated endosymbiotic bacteria [PDF]

, 2011
Nitric oxide (NO) is a gaseous signalling molecule which becomes very toxic due to its ability to react with multiple cellular targets in biological systems. Bacterial cells protect against NO through the expression of enzymes that detoxify this molecule

Three‐Step Pulse Strategy Enhances Ultradilute Nitrate‐to‐Ammonia Conversion via Microenvironment and Mass Transfer Control

Advanced Science, EarlyView.
Electrochemical treatment of low‐concentration nitrate in wastewater is challenging. This study introduces a three‐step pulsed method that achieves near‐perfect efficiency in converting ultradilute nitrate to ammonia. Combined experiments and simulations reveal how pulsed strategy boost kinetics while suppressing competing reactions.
