Defect‐Engineered SrTiO3‐x for Flexoelectric‐Dominated Catalysis

EcoEnergy, EarlyView.
Defect‐engineered SrTiO3‐x nanoparticles with enhanced flexoelectricity efficiently degrade pollutants and produce hydrogen under ultrasound‐driven flexocatalysis. This materials–engineering approach offers a scalable pathway for combining environmental remediation and renewable energy applications. ABSTRACT Flexocatalysis provides an alternative route

Metal‐Organic Framework‐Templated Construction of Internal Electric Field and S‐Vacancy Defect‐Engineered S‐Scheme Heterojunction for Enhanced Photocatalytic Hydrogen Evolution

EcoEnergy, EarlyView.
A Bi2S3@ZnIn2S4 heterojunction with abundant sulfur vacancies was fabricated through MOF‐templated in situ synthesis. DFT calculations and experiments confirm the presence of an internal electric field (IEF) and S‐scheme charge transfer. The optimized catalyst shows a superior H2 evolution rate of 5.13 mmol·h−1 g−1 under visible light, which is 11.7 ...

Decorating Carbon Nitride via the Integration of Phosphorylation with Carbon Self‐doping toward Enhanced Photocatalytic Hydrogen Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The electron transfer from the grafted ATMP to the adjacent heptazine ring can induce the proton transfer of the hydroxyls on ATMP to Pt co‐catalyst nanoparticles. This coupling of proton transfer and electron transport also promotes the separation and transport of charge carriers and therefore advances the performance of photocatalytic hydrogen ...

Light‐Induced Structural Reorganization of Fe Centers Unlocks High Efficiency of Visible‐Light Photo‐Fenton Water Cleaning Catalyst

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Bimetallic Cu and Fe oxide species supported on porous silica with interparticle mesoporosity act as efficient photo‐Fenton‐like catalysts under visible light. Photogenerated electrons drive the Cu2+/Cu1+ redox cycle. Part of Cu1+ is responsible for the regeneration of the Fe3+/Fe2+ cycle at neutral pH. Light irradiation additionally induces structural

Influence of Ethanol Content on the Electrooxidation of Triethanolamine in Highly Apolar Media on Platinum Microelectrode

Reactions
Ethanol is widely used as an additive in fuels, so its effect on the electrochemical oxidation of triethanolamine was investigated on a 25 μm platinum microelectrode. Ethyl acetate was applied as a cosolvent to increase the permittivity of the medium.

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

Phenolic profile of selected grape (Vitis vinifera L.) varieties in the course of ripening and Botrytis cinerea infections

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Grapevine phenolic compounds play key roles in plant defense and wine quality. Composition depends on factors such as maturity and infections such as grey mold caused by Botrytis cinerea. Grapevines respond to infections by actively modifying their phenolic profile.
