MoO3/Nb2O5 Composites Prepared by Wet High-Energy Ball Milling: Structural Evolution, Physicochemical Properties, and Catalytic Performance in Biodiesel Production

The development of heterogeneous catalysts with suitable structural and physicochemical properties is important for catalytic processes involving renewable feedstocks. In this study, Nb2O5 and MoO3/Nb2O5 composite catalysts were prepared by high-energy wet milling, systematically characterized, and subsequently evaluat...

Modeling and Scaling of Hydroxyapatite Synthesis by Combustion Reaction for Biomedical Applications

Abstract This work presents a trend-based mathematical model to optimize and control the pilot-scale synthesis of hydroxyapatite (HAp) via solution combustion. The study establishes a predictable relationship between reaction temperature and precursor mass to overcome typical scaling challenges, such as thermal gradien...
