Summary: Sonodynamic therapy (SDT) has shown promise as a cancer treatment, and researchers have developed ultrathin nanosheets as highly efficient sonosensitizers for SDT. The nanosheets undergo a phase transformation from polycrystalline to amorphous, resulting in higher reactive oxygen species (ROS) generation activity under ultrasound (US) irradiation. The enhanced performance of the nanosheets can be attributed to defect generation and electronic structure changes caused by the phase transformation. With polyethylene glycol modification, the nanosheets can effectively induce cell death in vitro and tumor eradication in vivo under US irradiation.

Summary: Doping tungsten (W) enhances the electrochemical performance of lithium titanate (LTO) anode by altering its crystalline and electronic structures, as well as electronic/ionic conductivities. The reduction of Ti4+ ions to Ti3+ ions induced by W6+ increases the room-temperature electronic conductivity, while the lattice spacing increases on the substitution of W6+ at Ti4+ octahedral sites, resulting in improved room-temperature Li-ion conductivity/diffusivity. The electrochemical characteristics of LTO are influenced by the dopant type, doping concentration, substitutional site of the dopant, resulting structural variations, and varying electronic/ionic conductivities and conduction mechanisms.

Summary: Ferromagnetic metals have the potential for use in ultralow-power-consumption spintronic devices due to their high Curie temperature and robust magnetization. However, there is a lack of reliable solutions for giant and reversible voltage control of magnetism in ferromagnetic metal films. In this study, a novel space-charge approach is proposed, which allows for achieving a large modulation of magnetism in Co/TiO2 multilayer granular films under low voltage. The results demonstrate the potential of this approach in modulating magnetism in ferromagnetic metals and pave the way for the development of ionic-magnetic-electric coupled applications.

Summary: In this study, a metal-free carbon catalyst NDPC-1000 with a graphitic N-regulating defect structure was designed for anion-exchange membrane fuel cells (AEMFCs) through theoretical calculations and experiments. The graphitic N was found to tailor the charge density of defects to enhance the adsorption energy-activity relation, and the high durability was attributed to the dissociation energy of the C-N covalent bond. The synthesized NDPC-1000 demonstrated excellent ORR activity and durability in alkaline media, achieving a peak power density of 913 mW cm(-2) and a voltage decay of approximately 25% after 100 hours of continuous operation.

Summary: The capacity degradation mechanism of LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode material in lithium-ion batteries under high operation voltage was investigated. It was found that at a cut-off voltage of 4.9 V, NCM811 undergoes a crystal structure evolution from a layered structure to a rock-salt phase, accompanied by severe intergranular cracks. This is different from the generally accepted structure evolution observed under lower cut-off voltages of 4.3 and 4.7 V. Electron energy loss spectroscopy analysis confirmed the reduction of Ni and Co from the surface to the bulk, contradicting the previously reported Li/Ni interlayer mixing. The degradation mechanism of NCM811 at 4.9 V was attributed to the formation of intergranular cracks induced by defects, the direct formation of the rock salt phase, and the reduction of Ni2+ and Co2+ phases from the surface to the bulk.
