One‐Step Solid‐State Synthesis of Sandwich‐like, Porous C–SnS2 Matrix Composites as Anode Materials for Rechargeable Lithium Ion Batteries

open access: yesSmall Science, EarlyView.
A one‐step solid‐state method is developed to synthesize SnS2 particles, which are embedded in sandwich‐like, porous polyacrylonitrile (PAN)‐based matrix phase (C–SnS2) for use as anode active materials for rechargeable lithium‐ion batteries. The performance of this SnS2‐based anode active material is compared to that of materials prepared by solid ...

Power of the Many‐Body Force: Magnitudes and Angles of Atomic Van der Waals Dispersion Forces in Extended Molecular Systems

open access: yesSmall Structures, EarlyView.
Many‐body dispersion (MBD) forces are stronger, longer‐ranged, and more accurate than pairwise van der Waals (vdW) models. By comparing polyethylene melts, benzene solutions, and fullerenes, it is shown that a slower‐decay corrected pairwise scheme can recover MBD magnitudes.

SFNIC: Hybrid Spatial‐Frequency Information for Lightweight Neural Image Compression

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Neural image compression (NIC) has shown remarkable rate‐distortion (R‐D) efficiency. However, the considerable computational and spatial complexity of most NIC methods presents deployment challenges on resource‐constrained devices. We introduce a lightweight neural image compression framework designed to efficiently process both local and ...
