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 ...

Assessing the balance between greenhouse gases and ammonia emissions from Irish pastures amended with cattle slurry [PDF]
, 2012 Agriculture in Ireland is the main source of ammonia (NH3) and contributes 30% of greenhouse gas emissions (GHG), with the majority of these emissions associated with livestock production.

Autotrophic ammonia oxidation in a deep-sea hydrothermal plume
, 2004 Direct evidence for autotrophic ammonia oxidation is documented for the first time in a deep-sea hydrothermal plume. Elevated NH(4) (+) concentrations of up to 341+/-136 nM were recorded in the plume core at Main Endeavour Field, Juan de Fuca Ridge. This

Adipocyte‐Derived Leptolin Enhances Energy Expenditure and Prevents Obesity
Advanced Science, EarlyView.We identified a novel adipokine, which we named leptolin. In humans, leptolin levels in white adipose tissue were positively correlated with exercise and negatively associated with body mass index. We observed elevated leptolin in serum from athletes and lower leptolin in serum from obese individuals.

Co-occurrence of aerobic ammonia oxidation, anaerobic ammonia oxidation and nitrite oxidation in oxic riverbeds and their relationships with net nitrification efficiency [PDF]
, 2019 PhDIn short term, re-mineralized nitrogen as ammonia can either be conserved in an ecosystem through its complete oxidation to nitrate e.g. ‘efficient nitrification’ or lost via oxidation to N2 gas e.g., ‘inefficient nitrification’. Here, 15N tracers and

Advanced Science, EarlyView.ABSTRACT Diabetes mellitus‐induced erectile dysfunction (DMED) is a highly prevalent complication among diabetic patients; however, its underlying pathogenic mechanisms remain incompletely understood. Metabolic disorder is a hallmark of diabetes, yet its precise contribution to DMED progression is not well defined.

Advanced Science, EarlyView.The pholidota‐inspired electronic skin is successfully constructed, originally realized four‐state reversible switching of terahertz‐wave reflection, absorption, transmission, and secondary reflection. In response to external demands, it issues deformation instructions, verifies the deformation state after the equipment executes the action, and thus ...
