Enhancing Silica Extraction from Rice Husk Ash Using Acid Solvent and Polyethylene Glycol-400: Efficiency and Mechanism
Silica derived from agricultural waste offers a sustainable pathway for producing advanced biomaterials, however, precise control over purity, structure, and morphology remains a challenge for dental applications. This study systematically investigates the effects of acidic solvent and polyethylene glycol-400 (PEG-400)...
