Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Mechanochromic Organic Materials: Molecular Mechanisms and Multidimensional Applications
Advanced Physics Research, EarlyView.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 ...
