Three‐Dimensional Printed Microarchitected Hierarchically Porous Biodegradable PLA/S/CNT Nanocomposite Electrodes for High‐Performance Lithium–Sulfur Batteries

open access: yesAdvanced Materials Technologies, EarlyView.
Hierarchically microarchitected PLA/S/CNT cathodes are fabricated via scalable fused filament 3D printing as high‐sulfur‐loading hosts for rechargeable lithium–sulfur batteries. The assembled Li–S cells with sulfur loadings up to 17 mg cm−2 deliver an areal capacity of 9.2 mAh cm−2 and retain 96% of their discharge capacity after 100 charge–discharge ...

Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced 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
