Advanced Bismuth-Based Anode Materials for Efficient Potassium Storage: Structural Features, Storage Mechanisms and Modification Strategies.
Nanomicro Lett
January 2025
Department of Materials Science and Engineering, College of Chemistry and Materials Science, Jinan University, Guangzhou, 510632, People's Republic of China.
Potassium-ion batteries (PIBs) are considered as a promising energy storage system owing to its abundant potassium resources. As an important part of the battery composition, anode materials play a vital role in the future development of PIBs. Bismuth-based anode materials demonstrate great potential for storing potassium ions (K) due to their layered structure, high theoretical capacity based on the alloying reaction mechanism, and safe operating voltage.

Most antibiotics are ineffective against Gram-negative bacteria owing to the existence of the outer membrane (OM) barrier. The rational design of compounds to expand their antibacterial spectra of antibiotics solely targeting Gram-positive pathogens remains challenging. Here, the design of skeletons from natural products to penetrate the OM are deciphered.

National Key Laboratory of Helicopter Aeromechanics, Nanjing University of Aeronautics & Astronautics, Nanjing, 210016, China.
In this work, the regulation of liquid self-transport is achieved through architectural and thermal coupling, transitioning from free surfaces to open channels. Hierarchical structures inspired by the skin of a Texas horned lizard are designed, with the primary structure of wedged grooves and the secondary structure of capillary crura. This design enables advantages including long-distance self-transport, liquid storage and active reflux management on free surfaces, directional transportation, synthesis and detection of reagents in confined spaces, as well as controllable motion and enhanced heat dissipation in open channels.

The rheological behavior of porous ionic liquids comprising ZIF-8 suspensions in two Newtonian ionic liquids - trihexyltetradecylphos- phonium bis(trifluoromethylsulfonyl)imide and tri- hexyltetradecylphosphonium chloride - exhibited distinct and unexpected differences. ZIF-8 suspensions in the bis(trifluoromethylsulfonyl)imide-based liquid showed Bingham behavior with a measurable yield stress, whereas those in the chloride-based liquid remained Newtonian, even at high solid volume fractions of up to 17.4%.

Single-atom catalysts (SACs) have emerged as a focal point of research in the field of heterogeneous catalysis. This paper reviews the progress in the studies of single atoms as promoters in various catalytic reactions, elucidating their distinctive role in comparison to the dominant active sites. We provide a discussion on the application of single-atom promoters (SAP) within host-guest systems in various catalysts, including metal oxide supported catalysts, molybdenum carbide-based catalysts, bimetallic catalysts, and others.
