Simulating the magnetic domain wall dynamics in ferromagnetic materials is crucial for designing spintronics devices, but including material imperfections is often challenging. Here, the effects of individual dislocations on domain wall dynamics in thin films of iron is investigated by micromagnetic simulations.

Hypercrosslinked polymers are promising materials for separation membranes due to their low cost and high porosity. Here, continuous hypercrosslinked polymer membranes are prepared using interfacial polymerization that effectively rejects small dye molecules with high water flux.

Highly sensitive and selective gas-sensing materials are important for applications ranging from environmental monitoring to breath analysis. Here, the gas sensing response of the heterointerface between graphene and nickel phthalocyanine is investigated by first-principles calculations and tested in a chemiresistor device exposed to NH₃ and NO₂ at room temperature.

Band degeneracies at the Fermi level in topological semimetals are sources of intriguing interference effects between electronic states around the degeneracy points. Here, the RE₈CoX₃ compounds, with RE = rare-earth and X = Al, Ga, or In, are proposed as realizations of ideal spinless Dirac semimetals hosting the fourfold degenerate band-crossing points without the spin degrees of freedom.

Mapping the distributions of various rare-earth dopants when combined within a host material is challenging, Here, a fast and precise approach to mapping rare-earth doping distribution based on a commercial UV-Vis scanner shows that dopants locally modify the optical properties of the material.

Phase-changing materials such as FeRh, undergoing a first-order phase transition from antiferromagnetic to ferromagnetic near room temperature, are attractive for various applications. Here, terahertz time-domain spectroscopy provides evidence that the conductivity change in FeRh during the phase transition originates from a restructuring of its band structure.

Combining in-memory sensing and computing is key to the realization of machine vision systems in artificial intelligence applications. Now, non-volatile magnetic memory and optical sensing capabilities are integrated in two-dimensional Fe₃GaTe₂/WSe₂/Fe₃GaTe₂ junctions operating at room temperature.

Sonodynamic therapy is a precise and non-invasive anticancer treatment but is ineffective in killing cancer cells and triggering robust immune responses. Now, a dual-ligand bimetallic framework allows controlled nitric oxide release by ultrasound that is effective for sono-immunotherapy.

Yury Gogotsi is a pioneer of the burgeoning field of 2D MXenes. Here he offers his insight on the history of MXene development, promising applications and what he is excited about.

There is growing interest in reducing the chemical complexity of engineering alloys. Here, an Mg-Ca alloy for use in bone fixation has less than 1 weight % calcium, and achieves strength and ductility superior to many conventionally-processed magnesium alloys.

Altermagnetism is attracting great interest as a new third type of collinear magnetic order, distinct by symmetry from conventional ferromagnetism and antiferromagnetism. Now, a mechanism for an interaction-induced formation of altermagnetism in isotropic crystals is presented, based on spontaneous orbital ordering.

Sodium-ion battery safety can be improved by using non-flammable electrolytes, but they are traditionally incompatible with carbon-based anodes. Now, low-concentration phosphate electrolytes modulated by anion-cation interactions are shown to work well with standard electrodes, displaying stable operation over a wide temperature range.
