Ion migration has direct and crucial bearing on the crystal lattice field, electron filling, orbital occupation and spin polarization, which in turn changes the physical properties. Electric field is an effective way to control ion migration, but it may include simultaneous movement of multiple ions and increase the complexity of the system. Therefore, controllable and selective single ion migration with an unambiguous mechanism is highly desired. Here, the magnetic moments of FeO could be reversibly controlled by ionic liquid gating on the basis of migration of pure protons. A bilayer graphene could serve as an ion sieve, allowing only protons rather than oxygen ions or hydroxyl groups to participate in the gating process, thus guaranteeing the reversibility of magnetic property changes. This work is expected to supply an ideal arena for electrically sketching the functionalities of solid state materials based on the selective ion migration.

Metal halide perovskites have garnered significant attention due to their exceptional photoelectric properties. The alkali metal doping strategy has been demonstrated to effectively modulate grain size, control crystallization kinetics, and adjust band gap characteristics in perovskite. This study employs the first-principles calculations to reveal that the selection of alkali metal species and their corresponding doping methodologies exert markedly distinct influences on both the electronic properties and ion migration kinetics of CsPbBr perovskites.

High entropy electrolytes show great potential in the design of next generation batteries. Demonstrating how salt components of high entropy electrolytes influence the charge storage performance of batteries is essential in the tuning and design of such advanced electrolytes. This study investigates the transport and interfacial properties for lithium hexafluorophosphate (LiPF) in ethylene carbonate and dimethyl carbonate (EC/DMC) solvent with commonly used additives for high entropy electrolytes (LiTFSI, LiDFOB, and LiNO).

Global water scarcity demands next-generation desalination technologies that transcend the limitations of energy-intensive processes and salt accumulation. Herein, a groundbreaking interfacial solar steam generation system capable of simultaneous hypersaline desalination and ambient energy harvesting is introduced. Through hierarchical hydrogel architecture incorporating a central vertical channel and radial channels with gradient apertures, the design effectively decouples salt transport and water evaporation: solar-driven fluid convection directs water outward for evaporation, while inward salt migration prevents surface crystallization and redistributes excess heat.

The formation and recrystallization of ice crystals during freezing causes irreversible structural damage to the dough matrix, which is characterized by the cold denaturation of the gluten protein structure and the degradation of the gluten network structure. Polysaccharides are widely used to improve the quality of frozen dough owing to their excellent water-holding and viscosity. Current research has shown that polysaccharides mitigate the physical damage of ice crystals on the gluten protein structure mainly by modifying the water status of frozen dough to inhibit the ice crystallization process.

Radiation-induced skin injury (RSI) remains a significant clinical challenge due to persistent oxidative stress, chronic inflammation, and impaired tissue regeneration. It is demonstrated that RSI is accompanied by dysregulation of the immune microenvironment, wherein macrophages act as key regulators of all pathological cascades. Here, we developed a dual network hydrogel (Gel/SA@MXene) through dual cross-linking via UV irradiation and calcium ions to accelerate radiation-combined wound healing.
