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)

Rainfall-driven pathway switching reorganizes nitrate transport and transformation in a terrace-ditch-pond system

Agricultural Water Management
Agricultural terrace-ditch-pond (TDP) systems are common connected drainage units in hilly agricultural regions, where terraces, ditches, and ponds jointly regulate runoff and nutrient transport. Although nitrate sources and catchment-scale runoff export

Oxidant‐Expedited Synthesis of H‐Phosphonates

European Journal of Organic Chemistry, EarlyView.
An exceptionally mild method for synthesis of alkyl and aryl H‐phosphonates from phosphites is reported, requiring only water and O2 (including air) as reagents. Mechanistic experiments indicate that the role of O2 (and other oxidants) in the transformation is to promote a radical mechanism, and that H2O functions to provide both the hydrogen and the ...

Production of bioethanol from residual barley and utilization of fermentation co‐products in animal nutrition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The search for sustainable alternatives for bioethanol production has encouraged the valorization of agro‐industrial residues. This study evaluated the use of residual barley as a feedstock for bioethanol production and as a potential ingredient for ruminant feed.

Sol–gel synthesis of ZnO@SiC heterojunctions from photovoltaic waste for enhanced paracetamol photodegradation

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Exponential growth in photovoltaic energy production has created a critical environmental challenge: managing silicon carbide (SiC) waste from wafer cutting processes. This study addresses this challenge by transforming photovoltaic waste into high‐value photocatalytic materials.
