Summary: Due to the increasing demand for electronic reliability and defense security, the research on broadband and lightweight microwave absorption materials has surged. Porous composites, with their ability to attenuate waves in a balanced manner and match impedance, have the potential to be high-performance absorbers. By using a solvothermal technique, FeSe2/rGO composites with a porous topology were generated and their electromagnetic properties can be finely tuned by varying the weight of rGO. The combination of porous structure and appropriate electromagnetic parameters improves impedance matching and attenuation capability, resulting in outstanding microwave absorption performance.

Summary: Current commercial nickel (Ni)-rich cathodes for high-energy lithium (Li) batteries often contain toxic and expensive Mn/Co, which causes issues like transition-metal dissolution and surface degradation. This study compares a Mn/Co-free Ni-rich Li-Ni0.94Fe0.05Cu0.01O2 (SCNFCu) cathode with acceptable electrochemical performance to a Mn/Co-containing cathode. Despite slightly lower discharge capacity, SCNFCu cathode maintains 77% of its capacity after 600 cycles, outperforming the high-Ni LiNi0.9Mn0.05Co0.05O2 (SCNMC) cathode (66%). Fe/Cu ions in the SCNFCu cathode reduce structural disintegration, undesirable reactions, and Li loss. This discovery opens up new possibilities for developing Mn/Co-free cathode materials for next-generation high-energy Li batteries with the flexibility and scalability of SCNFCu.

Summary: Silicon (Si)-based materials are highly sought after as promising anode materials for next-generation lithium-ion batteries (LIBs) due to their high theoretical mass-specific capacity, moderate working potential, and abundance in the earth's crust. However, the electrochemical performance is hindered by volume variation, resulting in poor cyclability and electrode failure. Nanostructured Si anodes and their composite electrodes could potentially overcome these challenges by providing strain relaxation, short lithium diffusion distance, improved mass transport, and efficient electrical contact. This review comprehensively summarizes the chemistry, uniqueness, synthetic strategies, and practical applications of Si-based materials and discusses the research outlook for Si/SiOx/C-based materials in the future.

Summary: Drug carriers have been effectively used in modern medication, and this study investigates the decoration of the Mg12O12 nanocluster with transition metals (Ni and Zn) for the adsorption of metformin (an anticancer drug). The results show that Ni and Zn decoration provides good attachment and detachment of the drug, with a reduction in the energy band gap and efficient charge transfer. The Ni and Zn-decorated Mg12O12 nanoclusters are recommended as efficient carriers for metformin, offering a novel direction for the future development of drug carriers.
