A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Ammonia production by microbubbles: A theoretical analysis of achievable energy intensity

Ultrasonics Sonochemistry
The present paper studies the energy intensity of ammonia production by a freely oscillating microbubble placed in an infinite domain of liquid. The initial content of the bubble is a mixture of hydrogen and nitrogen.

Oxygen‐Vacancy‐Engineered Ru–V Dual Sites in InVO4 for Synergistic Photocatalytic N2 Activation and Reactive Hydrogen Supply

EcoEnergy, EarlyView.
This study developed a catalyst composed of Ru nanoparticles directionally anchored at the oxygen vacancies of indium vanadate. Oxygen vacancy not only forms unsaturated V sites but also serves as an anchoring site for Ru nanoparticles, establishing a stable Ru‐V coordination structure through electronic metal–support interactions.

Multidimensional Engineering Enabling Rate‐Matched C−N Coupling for Efficient Organonitrogen Electrosynthesis

EcoEnergy, EarlyView.
This review introduces rate matching as a unifying design principle for efficient electrochemical C−N coupling and highlights multidimensional engineering of catalysts, interfaces, and reactors to synchronize the generation of carbon‐ and nitrogen‐containing intermediates, balance their surface coverages, maximize C−N bond formation, and enable ...

Prognostic role of TAPSE to PASP ratio in outpatients with left ventricular systolic dysfunction

ESC Heart Failure, Volume 12, Issue 2, Page 912-922, April 2025.
Abstract Aims Few data are available regarding the role of tricuspid annulus plane systolic excursion to pulmonary artery systolic pressure (TAPSE/PASP), a measurement of right ventricular to pulmonary artery coupling, in patients with chronic heart failure and left ventricular systolic dysfunction.

On the Variability of Results for Cylinder Flow: A Systematic Analysis of Parameter Sensitivity Within the Lattice Boltzmann Method

International Journal for Numerical Methods in Fluids, EarlyView.
This study systematically investigates the variability of cylinder flow results. We provide a comprehensive overview of literature values and, using the lattice Boltzmann method (LBM), show that insufficient convergence studies and variations in simulation parameters are a plausible cause for the significant spread in data.
