Article Synopsis
  • Research is focusing on renewable fuels like biodiesel due to the rising costs and unreliability of conventional fuels, with biodiesel being produced from waste cooking oil (WCO) using specific catalysts.
  • A CaO catalyst was synthesized from snail shells and modified with ZnO and TiO, yielding biodiesel from WCO with an impressive success rate—80% for CaO alone and up to 95% with modifications.
  • The study confirmed that optimal conditions for the highest biodiesel production included specific catalyst weight, temperature, methanol-to-oil ratio, and reaction time, indicating that the snail shell-derived catalysts could be a cost-effective alternative to traditional catalysts.

Due to their improved structural and functional properties as well as biocompatibility, biodegradability, and nontoxicity, chitosan and its nanoparticles are currently grasping the interest of researchers. Although numerous attempts have been made to apply chitosan and its derivatives to biological applications, few have reported in achieving its pharmacological and drug delivery. The goal of the current work is to provide a summary of the chitosan biopolymer's physical, chemical, and biological properties as well as its synthesis of nanoparticles and characterization of its modified nanocomposites.
