Summary: Soil salinity is a detrimental abiotic stress for plants, while light plays a core role in regulating plant growth and response to stress. This study reveals that Arabidopsis seedlings are more salt-tolerant in light conditions, and the photoreceptors phyA and phyB are involved in this mechanism. The results demonstrate that phyA and phyB physically interact with SOS2 to enhance its activity and promote salt tolerance. Furthermore, SOS2 phosphorylates PIF1 and PIF3, negatively regulating salt tolerance. Overall, this study expands our understanding of how plants adapt to salt stress in different light environments.

Summary: In this study, a self-supported cobalt nickel bimetallic phosphide nanoneedle array (Co-Ni-P/NF) is designed to achieve excellent bifunctional activity for the hydrogen evolution reaction (HER) and methanol electro-oxidation reaction (MOR). The p-n heterogeneous junctions formed between nickel phosphide and cobalt phosphide promote electron accumulation on CoP, enhancing HER activity, while the increased MOR activity is attributed to in situ generated holes in Ni2P. Benefiting from optimized interface/surface electronic structures, Co-Ni-P/NF exhibits a high current density of 100 mAcm(-2) at a low voltage of 1.45 V in a two-electrode electrolyzer. The faradic efficiency for both HER and MOR reaches 100%, demonstrating the excellent bifunctional catalytic activity of Co-Ni-P/NF nanoneedle arrays. This work provides insights into the development of novel bifunctional electrocatalysts for value-added chemical production and highly efficient hydrogen evolution.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.
