In \({A}_{2}{BB}^{{\prime} }{{{\rm{O}}}}_{6}\) double perovskites, nonmagnetic isovalent \({B}^{\prime}\) cations (d⁰ or d¹⁰) can tune the magnetic behavior of the B sublattice. Here, the authors show that d⁰/d¹⁰ \({B}^{\prime}\)-site doping in Ba₂GdNb_xSb_1−xO₆ tunes magnetic interactions and enhances magnetocaloric performance, offering a route to efficient adiabatic demagnetization refrigeration materials.

Muon-spin rotation is combined with AC susceptibility and electrical resistivity measurements to investigate superconductivity, spin-stripe order, and structural response in 1/8-doped LBCO cuprates under in-plane uniaxial stress applied 45^∘ to the Cu–O bond direction.

Mechanical recycling of lithium-ion batteries can release ultrafine particles and carbon nanotubes, posing occupational health and safety concerns. Here, the authors developed and validated an aerosol monitoring approach to simultaneously detect and quantify ultrafine particles and airborne carbon nanotubes released during lithium-ion battery comminution.

Mucus is vital for host defense, but its complexity and the limitations of current mucin models hinder its study. Here, the authors developed a synthetic mucus-mimetic hydrogel based on human milk oligosaccharide-functionalized dendritic polyglycerol, which mimics the viscoelastic properties of human mucus, inhibits Pseudomonas aeruginosa biofilm formation, and shows potential as a topical antiseptic.

Magnetic nanomaterials enable secure, high-capacity information encoding. Here, the authors developed magnetic polymeric supraparticle tags and demonstrated two encoding strategies with magnetic particle spectroscopy for secure, high-density information encoding and authentication.

This study employs atomic electron tomography to resolve the three-dimensional atomic structures of amorphous Ge₂Sb₂Te₅ nanoparticles after femtosecond laser irradiation and room temperature aging, supported by first-principles calculations.

Zhong Lin Wang was the first to demonstrate a working Triboelectric Nanogenerator (TENG). Here we discuss his scientific background, promising applications for TENGs and commercialization challenges.

William Morris is the director of business development at Numat, a company commercializing metal-organic frameworks into products. Here he offers his insight on transitioning to industry, what businesses consider in commercial deployment, and suggestions to make research more applicable to the real world.

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.
