Harnessing Solar Energy for Ammonia Synthesis from Nitrogen and Seawater Using Oxynitride Semiconductors

Advanced Energy Materials, EarlyView.
In this work, the challenging green ammonia evolution is addressed by developing a photothermal system that utilizes nitrogen and natural seawater under simulated solar irradiation, employing ruthenium‐doped barium tantalum oxynitride semiconductors.

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, EarlyView.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

Influence of Metal Species and Content of Fe‐Ni‐Poly(heptazine imides) on their Properties as Electrocatalysts for Zinc‐Air Batteries

Advanced Energy Materials, EarlyView.
Iron/nickel‐modified poly(heptazine imides) are efficient, low‐cost bifunctional electrocatalysts for the oxygen reduction and evolution reactions in aqueous zinc–air batteries. Iron enhances oxygen reduction, while nickel single‐atoms deliver oxygen evolution activity comparable to RuO2.

A Scoping Review of Nudges for Enhancing Agricultural Policy

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Following PRISMA guidelines, we conduct a scoping review on 18 empirical studies on nudging interventions for farmers in Europe and the USA. The evidence on the effectiveness of nudges is mixed. Some studies demonstrate positive outcomes, particularly when nudges are combined with other interventions; others report no effect or negative ...

Atroposelective Suzuki–Miyaura Coupling to Form 2‐Amino‐2′‐Hydroxybiphenyls Enabled by sRuPhos

Angewandte Chemie, EarlyView.
We report a new chiral phosphine ligand, sRuPhos, which permits the highly enantioselective Suzuki–Miyaura coupling of ortho‐aniline and ortho‐phenol building blocks. This results in 2‐amino‐2′‐hydroxybiphenyls with very high enantiomeric excesses, products that will have application in pharmaceutical synthesis and ligand design for catalysis ...

Fully Developed Flow of Fourth Grade Fluid through the Channel with Slip Condition in the Presence of a Magnetic Field

Journal of Applied Fluid Mechanics, 2016
In this paper, to study the incompressible fully developed flow of a non-Newtonian fourth grade fluid in a flat channel under an externally applied magnetic field, an appropriate analysis has been performed considering the slip condition on the walls ...
