ChemSusChem, Volume 18, Issue 6, March 15, 2025.Perovskite oxide catalysts with reduced Co content, substituted by Fe and Ni, are synthesized and studied for their activity in the oxygen evolution reaction in alkaline media. An increase in the intrinsic catalytic activity (obtained by the (RctCdl)−1 product) of the base material (Ba0.5Gd0.8La0.7Co2O6‐δ) is seen for an as high as 70 % substitution of

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage
ChemSusChem, Volume 18, Issue 6, March 15, 2025.Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Food Chemistry International, EarlyView.The graphic illustrates the development of nuggets traditionally known as “wari” prepared with whole green grams and composite flour barnyard millet var. (PRJ‐1) and finger millet var. (VL‐M‐380) in a 1:1 ratio. The addition of millet significantly improved the nutritional value of nuggets, providing higher levels of protein, carbohydrates, fiber ...

Food Chemistry International, EarlyView.ABSTRACT Rice (Oryza sativa L.) is a vital staple crop for nearly half the world's population. This study investigates the levels of aflatoxins (AFB1, AFB2, AFG1, and AFG2) and selected heavy metals (Cd, Pb, and Cr) and essential elements (Mn, Fe, Mg, Cu, and Zn) in rice varieties cultivated in Fogera, Amhara Region, Ethiopia.
