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.
This study models how India’s expanding electric vehicle fleet could change demand for and requirements of lithium, nickel, cobalt, manganese, and graphite through 2060 under several deployment and battery-chemistry scenarios. Under the baseline scenario, EV battery demand reaches about 965 GWh by 2060, while recycling could reduce cumulative lithium demand by up to 54% and offset much of the demand for cobalt and manganese.
A ChemRxiv preprint reviewing 58 new materials-science foundation models found that 52 used a single data modality, while only six combined multiple modalities, and none combined multimodality with explicit physical grounding. The authors propose a framework that combines harmonized materials data, physics-aware multi-modal architectures, efficient specialization, and rigorous validation, although such a unified model has yet to be demonstrated.
A team of researchers led by the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) developed a powerful new approach that enabled them to directly observe how electrons interact with defects in advanced semiconductor devices with an unprecedented level of detail.
Professor Do Hyun Ryu's research team in the Department of Chemistry at Sungkyunkwan University (SKKU) has developed two new asymmetric catalytic methods for the precise synthesis of complex molecules using chiral organic catalysts. The team demonstrated that a single catalyst can promote two different carbon-carbon bond-forming reactions with high selectivity.
