A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems
Advanced Science, EarlyView.Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Aerobic nitrogen fixation in Azotobacter vinelandii [PDF]
, 1977 I ELECTRON DONATION TO NITROGENASEPaper I shows that the hypothesis, that a high ratio of (NADH + NADPH) / (NAD + + NADP + ) is the source of reducing power for nitrogenase in intact A.vinelandii, is invalid.

Nitrogenase activity in nodules.
, 2013 Nodules were formed by inoculation of a 1∶1 ratio of wild type to either ΔnifA or ::nifA mutants. Nodules were harvested 30-days post-inoculation and acetylene reduction activity was determined using a HP 6890 Series gas chromatograph system (see Methods)

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies
Advanced Science, EarlyView.This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

Nitrogen fixation by a Bangladesh deepwater rice-field calothrix [PDF]
, 1990 In order to study the influence on blue-green algal nitrogenase activity of environmental variables in deepwater rice-fields (DWR), a laboratory study was planned on a DWR isolate of Calothrix (D764).
