Superconducting Hydride Mg2RhH6 Experimentally Achieved at Lower Pressure

Abstract Although tremendous progress has been made in recent years in the field of polyhydride superconductors, the realization of high critical temperature (Tc) superconductivity still relies on formidable high pressures. Searching for superconducting hydrides at lower pressure...

Gate-imprinted memory and light-induced erasure of superconductivity at KTaO3-based interfaces

Realizing non-volatile control of superconductivity is a key step toward integrating memory and quantum functionality in future information technologies. KTaO₃-based heterostructures uniquely host interfacial two-dimensional superconductivity and quantum paraelectric lattice back...

Beyond the Markovian limit: Exact solutions for active motion in a power-law viscoelastic bath

Active particles from bacteria to synthetic microswimmers often navigate viscoelastic media with complex relaxation dynamics. The classical active Brownian model that assumes instantaneous friction is clearly not applicable to describe such motility, while the non-Markovian proce...

MXene-Induced Adsorption of Transition Metals Stabilizes Lithium-Rich Manganese Cathodes against Voltage and Capacity Decay

Abstract Lithium-rich manganese-based materials (LRMO) have emerged as ideal cathode materials for high-energy-density lithium-ion batteries due to their high capacity (>250 mAh/g) and low cost. However, the continuous migration and dissolution of transition metal ions (TM...

Encapsulated CsPbBr3 quantum dots with asymmetric chiral magneto-optoelectronic responses

Quantum emitters having non-trivial spin polarizations are highly demanded for chiral quantum devices and quantum photonic technologies. Here we investigate the magneto photoluminescence spectroscopy of perovskite quantum dots encapsulated in silica and report an observation of c...

Synergistic Dual‐Channel Charge Separation in Cr‐TiO 2‐x for Solar H 2 O 2 Synthesis

ABSTRACT Solar‐driven hydrogen peroxide (H 2 O 2 ) synthesis offers a sustainable alternative to the energy‐intensive anthraquinone process, yet its efficiency is fundamentally constrained by the inability to simultaneously harness photogenerated electrons and holes in a balanced...

Spin-quenching cobalt center for efficient ammonia synthesis derived from oxide mixology

The spin polarization plays a critical role in heterogeneous catalysis by influencing the properties of active sites and thereby altering catalytic performance. However, precise construction of active sites with well-tuned spin states remains challenging. Here we demonstrate to m...

Dual Oxygen Precursors Boosting the Ionic Conductivity of Glassy Electrolytes for All‐Solid‐State Sodium Batteries

ABSTRACT Amorphous halide‐based solid electrolytes (SEs) are promising candidates for all‐solid‐state Na batteries (ASSNaBs) due to their structural flexibility and favorable mechanical properties. Among them, aluminum‐based halide electrolytes are particularly attractive owing t...

An engineered metal-to-insulator transition in a two-dimensional network of degenerate phosphorus quantum dots in silicon

Phosphorus quantum dots (QDs) in silicon are a prominent candidate for semiconductor quantum computing based on donor spins. In this work, we report the formation of degenerate phosphorus QDs with a radius of 3 nm confined in a two-dimensional plane in silicon. A multilayer of Si...
