Micro and nanosizing of Tamsulosin drug via supercritical CO2 antisolvent (SAS) process
Journal of CO2 UtilizationSupercritical anti-solvent (SAS) method is a solvent-free approach where supercritical carbon dioxide (SC-CO2) is used as anti-solvent and one can control the output particle size without disturbing the nature of the particles.

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies
Advanced Engineering Materials, EarlyView.Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...
