NANOMATERIALS
New type of magnetism discovered in 2D materials
In collaboration with international partners, researchers at the University of Stuttgart experimentally demonstrated a previously unknown form of magnetism in atomically thin material layers. The new magnetic state emerges in a system consisting of four atomic layers of chromium iodide.
New method measures energy dissipation in the smallest devices
Stanford University researchers combined theory, experimentation, and machine learning to quantify energy costs during a nonequilibrium process with ultrahigh sensitivity. They measured the entropy production of quantum dots to determine the ultimate speed limits for a device and how efficient it can be.

Tool for visualizing hydrogen fuels advances
Washington State University researchers developed a tool for viewing liquid hydrogen in an enclosed tube as it changes phases from liquid to gas, an important step in the lab’s partnership with aviation giant Airbus to accelerate efforts to produce a carbon-free commercial airplane.
3D-printed nuclear batteries could power long-duration space
South Australian engineering firm entX worked with University of Adelaide researchers to develop a 3D-printed betavoltaic device with high power densities. They are transitioning the GenX nuclear battery from a laboratory prototype to a pre-commercial reality.
MANUFACTURING
Researchers find a way to 3D print one of industry’s hardest engineering materials
Researchers at Hiroshima University and Mitsubishi Materials Hardmetal Corporation used hot-wire laser irradiation to produce tungsten carbide–cobalt cemented carbides.
Low-temperature, sinterless silica glass using 3D printing techniques
Yokohama National University researchers used 3D printing techniques to turn a novel polyhedral oligomeric silsesquioxane-based resin into silica glass at relatively low temperatures.

New materials could keep electrons moving in tiny chips
Northwestern University researchers developed a computational workflow that simulates how electrons move through ultrathin nanowires. By incorporating realistic defects and variations into the simulations, they identified candidate materials that are likely to retain high conductivity even with imperfections.
Tune a recipe for topological superconductors by choreographing electron interactions
By adjusting the ratio of tellurium and selenium, researchers at the University of Chicago Pritzker School of Molecular Engineering and West Virginia University can switch exotic quantum states on and off in iron telluride selenide, a material highly desired for quantum computing.
Laser‑written glass chip pushes quantum communication toward practical deployment
Researchers from the University of Padua, Politecnico di Milano, and the CNR Institute for Photonics and Nanotechnologies demonstrated a high‑performance quantum coherent receiver fabricated directly inside glass using femtosecond laser writing.
