Research Status and Development Trend of Macromolecular Structure and Model Construction of Different Coals

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal is a natural macromolecular substance composed of complex organic molecules and a small amount of minerals. Its chemical composition and microstructure are highly complex and variable, and no unified definition exists. This inherent structural complexity underscores the theoretical significance of constructing accurate macromolecular ...

ZnO‐Coated Silicon Oxide Nano‐Anode: Synergistic Enhancement of Cycling and Thermal Stability of Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Lithium‐ion battery anodes that maintain good performance and excellent stability under high temperature conditions. Silicon oxide (SiO) has great potential as a high‐capacity anode for lithium‐ion batteries, but its practical use is limited by excessive volume expansion (>200%) and rapid capacity fade, especially at high temperatures.

Flexible Chromatic VIS‐IR Meta‐Textile for Multi‐Scenario Stealth

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A flexible chromatic meta‐textile was developed for multi‐spectral stealth across VIS‐IR bands, combining low color difference, ultralow infrared emissivity, and passive radiative cooling. The textile exhibits excellent VIS wide‐angle compatibility, optical durability, and mechanical flexibility, offering a promising solution for advanced stealth ...

Universality in scattering by large-scale potential fluctuations in two-dimensional conductors

open access: yes, 2007
We study electron propagation through a random array of rare, opaque and large (compared the de Broglie wavelength of electrons) scatterers. It is shown that for any convex scatterer the ratio of the transport to quantum lifetimes \eta=\tau_{tr}/\tau_ ...

A Label‐Free Hyperspectral Imaging Device for Ex Vivo Characterization and Grading of Meningioma Tissues

open access: yesJournal of Biophotonics, EarlyView.
HyperProbe1.1 enables rapid, label‐free biochemical mapping of freshly resected meningiomas. By quantifying endogenous biomarkers such as cytochrome c oxidase, hemoglobin derivatives, and lipids, the system reveals molecular signatures consistent with tumor grading and generates spatial maps that visualize metabolic and vascular heterogeneity across ...
