MOx/Rh Metallene with Energetic Interfaces as Efficient Bifunctional Electrocatalyst for Durable Water Splitting

Advanced Science, EarlyView.
 . ABSTRACT Developing excellent activity and stability bifunctional electrocatalysts for alkaline water splitting remains challenging. This work constructs ultrathin MOx/Rh metallene heterostructures (M = Fe, Co, Ni) via atmosphere‐controlled solvothermal synthesis, achieving uniform MOx nanoclusters on Rh metallene with optimized interfaces. The FeOx/

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates
