Antibody-Mimicking Nanocluster Ameliorates Osteoporosis in Preclinical Model

Abstract Osteoporosis occurs due to the synergistic effect of increased bone resorption and decreased bone formation. However, a therapeutic approach that can simultaneously inhibit osteoclastic resorption and promote osteogenic activity directly is still lacking. Growing evidenc...

Water-oil interfacial kinetics control enables water-based organic solar cells with 12.59% certified efficiency

Organic solar cells (OSCs) are promising for clean-energy generation, but sustainable production remains constrained by hazardous organic solvents. Aqueous organic-semiconductor nanoparticle (NP) inks offer an environmentally friendly route to OSCs, yet low efficiency and limited...

Systematic opto-mechanical design approach for meter-long Nano-AKB mirror system at HEPS

A systematic opto-mechanical design approach is developed for a long Nano-AKB mirror system aimed at stable sub-50 nm hard X-ray nanofocusing. The approach integrates deformation–stiffness-balanced mirror clamping, hierarchical precision alignment, and thermomechanical stability...

Realization of Quantum Spin Hall Insulator Superlattice with Emergent Multigap‐Like Helical Edge States

ABSTRACT The functional quantum spin Hall insulators (QSHI), protected by time‐reversal symmetry against single‐particle backscattering, hold great promise for dissipationless quantum electronics. Realization of QSHI with gapped helical edge states, which would enable determinist...

Pressure‐Activated and Retained Blue Emission in Melamine Through Hydrogen‐Bond and Packing Regulation

ABSTRACT Pressure provides a direct way to regulate molecular packing and excited‐state relaxation in organic crystals, but retaining pressure‐induced emission after decompression remains challenging. Here, we report pressure‐activated and retained blue emission in melamine (MA),...

Prussian blue regulates ion dynamics in perovskite solar cells

Perovskite photovoltaics are limited by structural instabilities initiated during crystallization and amplified under operation. We report that a lattice-matched Prussian blue scaffold directs heterogeneous nucleation to produce highly oriented, strain-relaxed films. Its redox-ac...

Study of Supernova Neutrinos at ESSnuSB

In this paper, we have studied the sensitivity of the ESSnuSB far detector to supernova neutrinos. ESSnuSB is a proposed long-baseline neutrino experiment in Sweden, which will use a 538 kt water Cherenkov detector to probe the leptonic phase δCP by studying the second oscillatio...

Dynamic deformation and fracture of porous cement: A high-speed X-ray phase contrast imaging study

Investigations on mechanical responses and failure mechanisms of porous cement to dynamic compression are essential for its applications as impact energy absorption material. This study conducts split Hopkinson pressure bar tests along with in situ high-speed X-ray phase contrast...

Tuning Free Volume via Diamine Structure in 6FDA ‐Based Polyimide Membranes for He/Ne Separation

ABSTRACT Helium and neon are strategically important noble gases in semiconductor manufacturing and cryogenic technologies, yet their similar molecular sizes and inertness make separation challenging. Although membrane‐based separation offers an energy‐efficient alternative to cr...

Hydrogen Bond‐Engineered Dual‐Phase Cellulose‐Polyelectrolyte Ionogel for All‐Weather Health Monitoring and Human‐Machine Interaction

ABSTRACT Cellulose ionogels are highly attractive for next‐generation wearable and flexible electronics, sensing, and energy storage applications. However, synchronously enhancing mechanical and electronic performance without compromising environmental stability remains a signifi...

Investigation of Position-Dependent Signal Propagation Delay in Large-Pitch AC-LGAD Using a Two-Dimensional Transmission-Line Model

This paper presents a study of position-dependent signal propagation delay in large-pitch pixelated AC-coupled Low-Gain Avalanche Detectors (AC-LGADs). In AC-LGADs, a continuous resistive N+ layer and segmented AC-coupled readout electrodes enable charge sharing and simultaneous...

Exploring baryon semileptonic decays through polarization and entanglement

Abstract The unitarity of the Cabibbo–Kobayashi–Maskawa (CKM) matrix is a cornerstone of the standard model (SM). Precise tests of this unitarity require independent determinations of its elements, such as | V us |, which governs the transition between strange and up quarks. Curr...
