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),...

Coordinated operational optimization of a variable-speed pre-expander and bypass for compressed air energy storage

The discharge process of compressed air energy storage (CAES) is challenged by inlet throttling loss and off-design mismatch caused by continuously declining cavern pressure. To address this issue, a coordinated operational optimization integrating a variable-speed pre-expander w...

Interplay of Lattice Distortion and Cation Disorder Governs Li-Ion Transport in Cation-Disordered Rocksalt Cathodes

Abstract Cation-disordered solids provide a chemically complex landscape in which local environments, lattice responses, and configurational disorder collectively influence ion transport. In cation-disordered rocksalt cathodes, Li+ diffusion has traditionally been interpreted usi...

Four-Phonon Scattering and Phonon Coherence in Monolayer Penta-CdO2 with Ultralow Lattice Thermal Conductivity

Abstract Two-dimensional (2D) pentagonal materials have emerged as promising candidates for low-lattice-thermal-conductivity applications owing to their extraordinary geometry structures and strong intrinsic anharmonicity. However, the roles of high-order phonon scattering and ph...

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...

Laminae Control on Pore Space Heterogeneity in Lacustrine Lucaogou Formation: Insights from SANS Studies

Abstract Laminated shales in the Lucaogou Formation exhibit strong pore heterogeneity, and the quantitative relationship between lamina types and pore structure remains poorly constrained. This study investigates how different laminae control pore distribution, connectivity, and...

Neutron Total Scattering Investigation of the Dissolution Mechanism of Chitotriose in Alkali/Urea Aqueous Solutions

Abstract Despite the promise of alkali/urea aqueous solutions as green solvents, the atomistic-scale mechanism of chitin dissolution remains elusive. In contrast to the ability to dissolve cellulose, the order of alkali effectiveness for dissolving chitin is potassium hydroxide (...

Full event interpretation with machine-learning-based particle-flow reconstruction in the CMS detector

Abstract The particle-flow (PF) algorithm constructs a global description of each particle collision by producing a comprehensive list of final-state particles, and is central to event reconstruction in the CMS experiment at the CERN LHC. The existing PF implementation relies on...

Accelerating Materials Discovery: A Review of Machine Learning in X‐Ray Absorption Spectroscopy

X‐ray absorption spectroscopy (XAS) is a critical technique for probing the local structural and electronic properties of materials. Advanced synchrotron radiation facilities generate complex, high‐dimensional spectra, which pose significant challenges for traditional analysis me...

Holistic Inside‐Out Reconfiguration of Ni‐Rich Cathodes via a Thermally Self‐Driven Strategy for Exceptional Chemomechanical Stability

ABSTRACT Ni‐rich layered oxides (LiNi x Co y Mn 1− x − y O 2 , x ≥ 0.8) are indispensable for high‐energy‐density lithium‐ion batteries, yet they suffer from severe chemomechanical degradation driven by the synergy of internal microcracking and interfacial parasitic side reaction...

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...

Atomically Precise Pt 3 Cu 2 Clusters Restore Energy Metabolism via Targeted Succinate Degradation

ABSTRACT Succinate is a critical intermediate for the tricarboxylic acid cycle, whose abnormal accumulation can disrupt energy homeostasis and trigger systemic inflammatory injury across dominant metabolic organs. Targeting succinate thus represents a pivotal strategy to reestabl...
