Researchers at CUNY’s Advanced Science Research Center have created an ultra‑thin metasurface chip that converts infrared light into visible light while steering the output beam. The device shifts 1530 nm infrared to 510 nm green via third‑harmonic generation and directs the beam by simply changing the incoming polarization. Laboratory tests show a 100‑fold efficiency boost over comparable non‑resonant designs, achieving precise angle control without any moving parts. The geometry‑driven approach can be adapted to other nonlinear materials and wavelength ranges, opening pathways for compact LiDAR, quantum optics, and integrated photonic systems.
Physicists at Auburn University have shown that even weak magnetic fields dramatically alter the behavior of dusty plasmas, a hybrid state of matter found in space and labs. By magnetizing electrons, the fields change how dust grains acquire charge, speeding...
Scientists have created a three‑layer electrode that simultaneously captures carbon dioxide from exhaust streams and converts it into formic acid. The device outperforms existing technologies, delivering about 40 % higher efficiency with pure CO₂ and maintaining strong output in simulated flue...
Physicists have uncovered a subtle magnetic order that persists in the pseudogap phase of quantum materials, linking it directly to the emergence of superconductivity. The discovery was made using an ultracold‑atom quantum simulator that mimics the Fermi‑Hubbard model, allowing researchers...
Researchers at Illinois’ Grainger College have identified the first physical mechanism by which magnetic fields impede carbon diffusion in iron. Using spin‑space averaging simulations, they showed that aligned iron spins increase the energy barrier for carbon atoms moving between octahedral...
Scientists at the University of Vienna have directly observed the elusive hexatic phase in an atomically thin silver iodide crystal, confirming that a true intermediate state between solid and liquid can exist in real two‑dimensional materials. The experiment used a...
UCLA chemists led by Neil Garg have overturned Bredt’s rule by synthesizing bridgehead carbon‑carbon double bonds in cage‑shaped molecules such as cubene and quadricyclene. The study shows these strained alkenes adopt a hyperpyramidalized, three‑dimensional geometry with bond orders around 1.5...
Researchers at the National Renewable Energy Laboratory have unveiled ULIS, an ultra‑low inductance smart power module built on silicon‑carbide that delivers record‑breaking efficiency and five‑fold higher energy density. The 1,200‑volt, 400‑amp device cuts parasitic inductance by 7‑9×, enabling ultra‑fast switching,...
Stanford researchers have demonstrated that a 3 nm silver ion coating on the LLZO solid electrolyte can dramatically improve its mechanical resilience, making it five times more resistant to cracking. The heat‑treated Ag⁺ layer infiltrates the ceramic surface, replacing lithium atoms...
Engineers at the University of Colorado Boulder, the University of Arizona and Sandia National Laboratories have demonstrated a surface‑acoustic‑wave (SAW) phonon laser that generates coherent vibrations on a single chip. The device combines silicon, lithium niobate and indium‑gallium‑arsenide layers to...
Researchers at TU Wien showed that electrons in the heavy‑fermion compound CeRu₄Sn₆ cease to behave as well‑defined particles near absolute zero, yet the material still exhibits robust topological characteristics. By probing the quantum‑critical regime, they detected an anomalous Hall effect...
Scientists at Florida State University have engineered a hybrid crystal by merging chemically similar manganese‑cobalt‑germanium and manganese‑cobalt‑arsenic compounds with mismatched symmetries. The resulting material exhibits skyrmion‑like cycloidal spin textures, a magnetic frustration that does not appear in either parent compound....
Physicists at TU Wien have created a one‑dimensional ultracold rubidium gas that transports mass and energy without any measurable resistance. By confining thousands of atoms to a single line with magnetic and optical fields, they observed that collisions merely exchange...
Researchers at the Indian Institute of Science have created molecular devices that can switch between memory, logic, selector, analog processing, and synaptic functions by tweaking ruthenium‑based complexes. Seventeen tailored complexes were synthesized, and subtle changes in ligands and ionic surroundings...
Researchers have introduced a gold‑based perovskite catalyst, Au/LaMn0.75Cu0.25O3, that achieves 95% acetaldehyde yield from bioethanol at 225 °C, surpassing the decade‑old Au/MgCuCr2O4 benchmark. The catalyst combines gold nanoparticles with a copper‑doped LaMnO3 perovskite, creating cooperative active sites that lower reaction barriers....
Researchers at Argonne National Laboratory and the University of Chicago identified internal‑stress cracking as the hidden flaw that drives capacity fade, shortened lifespans, and fire risk in advanced lithium‑ion batteries. The study shows that design rules borrowed from polycrystalline nickel‑rich...
Researchers at IFW Dresden and the ct.qmat cluster have identified platinum‑bismuth‑two (PtBi₂) as a genuine topological superconductor, where only the top and bottom surfaces become superconducting while the bulk remains metallic. The material exhibits an unprecedented six‑fold symmetric electron‑pairing pattern...
