Summary: Potassium-ion batteries (PIBs) are considered a promising alternative to lithium-ion batteries due to the abundance of potassium resources and low redox potential of potassium. Alloy-type anode materials have been extensively studied for PIBs due to their high theoretical capacities and abundant resources. However, the volume expansion effect during cycling significantly affects the cycling stability of alloy-type anodes. Various modification strategies, such as nanosized structure design and hybridization with conductive substrates, have been developed to address this challenge. In this review, the state-of-art progress and understanding of alloy-type anodes for PIBs, including K+ storage mechanism, electrochemical properties, and structure-property relationship, are summarized systematically.

Summary: KATP channels are octameric complexes consisting of four inward rectifying potassium channels and four sulfonylurea receptors from the ABC transporter family. These channels regulate a wide range of cellular activities by coupling intracellular ATP/ADP ratios with membrane excitability. Recent high-resolution cryoEM structures have provided insights into the complex interactions between channel subunits and their ligands, shedding light on the mechanisms of KATP channel regulation.

Summary: Advanced high strength steels (AHSS) are developed to reduce vehicle weight without sacrificing passenger safety. The incorporation of austenite in AHSS with carefully designed alloying elements and thermo-mechanical processing is crucial for enhancing the strain hardening behavior. Three different plasticity modes including dislocation plasticity, martensitic transformation, and deformation twinning can be observed in the austenite grains during small-scale tests, depending on stacking fault energy and crystal orientation. The remaining issues regarding the nano/micro-mechanical behavior of austenite in AHSS are discussed, aiming to shed light on the development of new high-performance steels at low cost.
