Integrated Valorization of Waste Biomass via Low‐Temperature Pyrolysis and Biochar Application as Heterogeneous Catalyst for SAF Production

Advanced Sustainable Systems, Volume 10, Issue 5, May 2026.
A biorefinery approach integrates the valorization of agri‐food waste through low‐temperature pyrolysis. The process concurrently yields functional liquid fractions and versatile biochars, which undergo extensive characterization to evaluate their potential in diverse technological applications. These materials serve as efficient renewable catalysts in

Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

Aggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a

From Wet Chemistry to Portable NIR: Robust High‐Throughput Compositional Models for Biomass Pretreatment

Journal of Chemometrics, Volume 40, Issue 5, May 2026.
ABSTRACT This study demonstrates a robust chemometric framework for high‐throughput compositional analysis of lignocellulosic biomass using a portable near‐infrared (NIR) spectrometer. Sugarcane bagasse solids produced by pressurized solvent fractionation (PSF) under batch and continuous conditions were analyzed to predict cellulose, hemicellulose, and
