Researchers developed a zwitterionic, fluorinated PAFS hydrogel electrolyte that reduces water-driven side reactions, promotes Zn²? transport, and forms a mechanically resilient organic-inorganic interphase on zinc. The material supported more than 900 hours of Zn plating and stripping, 1,500 cycles of Zn||MnO2 coin-cell operation, and an approximately 1 Ah pouch-cell demonstration.
Researchers have proposed a liquid-crystal-integrated polarization-multiplexed metalens that electrically selects two bright-field states and an interference-synthesized edge-enhanced state.
Researchers used thermal treatment or laser processing to tune polyacrylonitrile (PAN) fiber mats into separate thermoresistive temperature and piezoresistive pressure-sensing elements for flexible monitoring in high-temperature environments. The platform measured temperatures from 25 to 300 °C and pressures from 0 to 480 kPa, while combined loading above roughly 180 °C and 150 kPa exposed a structural limit.
Your shiny new smartphone and laptop can multitask between video calls, superfast searches, and detailed data crunching because of small, powerful microchips - the digital brains behind every computer's brawn.
Researchers found that selective deashing of Taixi anthracite alters the residual mineral profile prior to KOH activation, yielding porous carbons with distinct pore structures, surface chemistries, adsorption behavior, and electrochemical performance. HCl, NaOH, combined treatment, and no pretreatment each favored different properties, showing that precursor treatment can be used to tailor coal-derived porous carbon for specific applications.
Researchers engineered high-purity, (111)-oriented diamond with controlled carbon-13 and low nitrogen, then used 50 Hz noise mitigation and CPMG dynamical decoupling to extend a single NV-center electron spin’s coherence to 11.2(8) seconds while retaining a near-lifetime-limited optical linewidth of 16.9(4) MHz. The study shows that long spin coherence and coherent optical transitions can coexist in diamond, with implications for quantum-network nodes and sensing.
Researchers synthesized Al-substituted Na5FeS4 positive electrode materials for all-solid-state sodium batteries and found that slight aluminum substitution increased apparent sodium-ion transport while preserving high capacity. Na5Fe0.95Al0.05S4 delivered about 500 mAh g-1 in initial testing, maintained more than 460 mAh g-1 for over 70 cycles, and showed reversible sulfur-related structural changes during cycling.
A new approach that uses light to switch the magnetic states of a material could lead to faster, smaller and more energy-efficient data storage.
For decades, nonproliferation scientists and engineers at the U.S. Department of Energy's Argonne National Laboratory have helped convert the fuel in dozens of research reactors around the world so that they operate safely and more securely.
Argonne National Laboratory researchers proposed an AI-powered monitoring system that can spot blockages in the heat exchangers of molten-salt-cooled reactors in real time, helping prevent costly shutdowns and improve reliability for next-generation nuclear energy.
