Unleashing the Potential of Raman Spectroscopy to Estimate PEDOT:PSS Doping Level and Crystalline Morphology

Advanced Science, Volume 13, Issue 9, 13 February 2026.
Herein, the correlational changes of each PEDOT Raman peak to morphology and doping level are identified. Two equations are derived to estimate PEDOT π–π spacing and doping level from Raman spectra (from which mobility is also extracted). GIWAXS and XPS results validate the estimation equations.

RESEARCH ON BENDING⁃TORSION COUPLING VIBRATION CHARACTERISTIC OF COMPRESSOR SHAFT SYSTEM CONSIDERING HARD STIFFNESS CHARACTERISTIC

In order to investigate the influence of the coupling variable stiffness characteristics on the vibration behavior of the shaft system， the motor rotor⁃coupling⁃crankshaft⁃bearing of the compressor was taken as the object of study， and the Lagrange method was used to construct a coupled dynamics model of the bending⁃torsion of the shaft system.

Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications

Advanced Physics Research, Volume 5, Issue 2, February 2026.
Mechanochromic (MC) organic materials change color in response to mechanical force. This review elucidates the molecular mechanisms (e.g., aggregation‐induced emission, AIE) and explores their multidimensional applications in sensors, anti‐counterfeiting, biomedical devices, and structural health monitoring, providing a roadmap for future smart ...
