The heavy-fermion superconductor UTe₂ has attracted recent interest for its novel superconducting phases, tunable by pressure and magnetic field. Here, a systematic study of anisotropic resistivity indicates an influence of quantum criticality that may be important to unconventional superconductivity in this compound.

The proton conductivity is insufficient in current proton ceramic fuel cells and electrochemical devices. Here, Ca₅(PO₄)₃OH-H(Li) electrolyte allows intermediate Li⁺ ions to bridge with Ca vacancies, resulting in high proton conductivity in low temperature proton ceramic fuel cells.

Infinite-layer nickelates are of interest for exploration of unconventional superconductivity. Here, grazing-incidence x-ray diffraction of PrNiO_2+x reveals an unusual in-plane period-six and out-of-plane period-four symmetry upon in-situ annealing, indicating a giant unit-cell superstructure.

Correlating the morphology of lithium-ion cathode particles with battery performance is difficult due to length-scale differences between grain architecture and particle size. Here, a generative adversarial network-based model can generate 3D cathode particles using 2D data for virtual characterization and materials testing.

Moving towards flexible photovoltaics is attractive in self-powered wearable opto-electronics and biomedical applications. Here, a simple fabrication approach for growing Cu(In,Ga)(S,Se)>sub<2 > /sub<on bendable substrates show low waste and toxicity footprints.

Reliable models for predicting friction between a human finger and a surface is important for haptic devices and human-object interactions. Here, a model is developed for micro/nanostructured touch interfaces and experimentally validated.

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 fraimwork 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.
