GPU-accelerated finite-element method for the three-dimensional unstructured mesh atmospheric dynamic framework

Abstract. The three-dimensional unstructured-mesh finite-element atmospheric dynamical framework is gaining significance owing to its flexibility in representing complex topography and capability for multi-scale simulations in high resolutions. However, this framework has substan...

EEG-Neurofeedback Targeting Gamma Oscillations at the Parieto-Occipital Region Reduces Pain Perception

Pain is closely associated with both spontaneous and stimulus-evoked gamma oscillations, which differ in their phenomenology and their relationship to pain perception. These associations make gamma oscillations a promising target for pain interventions, such as closed-loop real-t...

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...

Building a Physics-Aware AI Ecosystem for Solid-State Hydrogen Storage Materials

Abstract Hydrogen storage remains a central bottleneck for scalable hydrogen energy systems due to the multiscale and coupled nature of the thermodynamics, kinetics, and microstructural evolution of hydrogen storage materials (HSMs). Although artificial intelligence (AI) has acce...

Chiral Iridium(III)Microcrystals with Mechano-TunableCircularly Polarized Luminescence

Abstract Multidimensional optical materials are of interest for high-security information encryption and anticounterfeiting, whereas conventional single-channel luminescent systems have low coding capacity and limited security. The combination of mechanochromic luminescence (MCL)...

Sustainable Recovery of Platinum Group Metals via Oxysalt Phase Reconstruction and Subsequent Deep Eutectic Solvent Leaching

Abstract The recycling of platinum group metals (PGMs) underpins sustainable development across semiconductors, new energy devices, and catalytic materials. Efficiently enriching and extracting these sparsely distributed PGMs from solid wastes such as spent catalysts still pose a...

Atmospheric Blocking Pattern as the Primary Driver of Subseasonal Greenland Ice Sheet Summer Melt Variability

ABSTRACT The anomalous summer melting of the Greenland Ice Sheet (GrIS) is one of the key signals of ongoing climate system changes. The complex spatiotemporal characteristics of GrIS and its impacts on global sea‐level rise have attracted increasing attention. Although previous...

Nano‑Ni-based multi-channel recyclable thermal interface material with dual-mode interface adaptability

The rapid miniaturization and integration of electronic devices demand highly efficient thermal management while concurrently exacerbating the global electronic waste (e-waste) crisis. Although thermal interface materials (TIMs) are important for heat dissipation, their end-of-li...

Colossal and ReversibleBarocaloric and Solvent-CaloricEffects in a T C-Adjustable Spin-CrossoverComplex

Abstract Barocaloric effects (BCE) represent an appealing refrigeration technology and have attracted great interest recently. However, most BCE materials still cannot meet real-world refrigeration requirements because of their fixed phase transition temperature TC and the signif...

Spontaneous ChlorineGeneration via Interfacial Oxidationof Chloride by O2 on Acidic Microdroplets

Abstract Reactive chlorine species significantly influence atmospheric chemistry, yet their sources remain inadequately defined. We have discovered a spontaneous formation pathway for substantial molecular chlorine (Cl2) from the oxidation of chloride (Cl–) through interfacial ox...

Sodium Lidar observed multiple sodium layer structures and their dynamical coupling mechanism

Abstract. On the night of 13 June 2013, the University of Science and Technology of China (USTC) sodium lidar observed multiple sporadic sodium layers (SSLs) and enhanced sodium patterns (ESPs) over Hefei, China (31.8°N, 117.3°E). These structures appeared at different times, col...

Solvent-AssistedDelamination of Boridene toward High-PerformanceMicro-Supercapacitors and Integrated Microsystems

Abstract Delaminating MoAlB-etched MoB into high-quality well-separated boridene nanosheets remains a formidable challenge. Current methods yield thick, restacked assemblies, severely limiting its potential for high-performance applications. Herein, we report solvent-assisted del...

Kinetically ProgrammedThermoresponsive PolyethyleneGlycol Shedding from Lipid Nanoparticles Improves mRNA Delivery

Abstract Polyethylene glycol (PEG) can stabilize nanoparticles and facilitate transport across biological barriers, yet the same PEG layer suppresses cellular uptake─a trade-off known as the PEG dilemma. Current strategies seek to overcome this limitation by enabling PEG shedding...

ODARRL: Obstacle- and Disturbance-Aware End-to-End Residual Reinforcement Learning for Underwater Robot Trajectory Tracking with Obstacle Avoidance

ROVs are essential for marine exploration and underwater operations, yet conventional teleoperation relies heavily on skilled human operators, and many autonomous methods stop at high-level planning rather than low-level actuation, limiting robustness in disturbed and cluttered e...

Macroevolutionary dynamics of Androsace s.l . (Primulaceae) across the Northern Hemisphere

Abstract Mountain regions of the Northern Hemisphere harbor exceptional biodiversity, yet the processes underlying species diversification and migration among these regions remain poorly understood. This study investigates the macroevolutionary dynamics of Androsace s.l ., a genu...

Star PolyelectrolyteCoacervates Enable Adaptive andRobust Enzyme Immobilization for Efficient Biocatalysis

Abstract Enzyme immobilization in solid porous supports often suffers from a trade-off among enzyme loading, mass transport, catalytic activity, and operational stability. Here, we report a liquid-like immobilization platform based on star polyelectrolyte coacervates (SPECs) form...
