Effect of Al2O3 and CeO2 Nanocatalysts on Biodiesel Yield from Pine and Soapnut Oils
Abstract: Abstract This study examines the influence of aluminium oxide (Al2O3) and cerium oxide (CeO2) nanocatalysts on the biodiesel yield obtained from two non-edible oils: pine oil and soapnut oil. Both oils were extracted through mechanical pressing and converted into biodiesel using the transesterification process. To understand how different process conditions, affect biodiesel production, a Box–Behnken Design (BBD) was used. Three key variables—methanol-to-oil ratio, catalyst concentration, and reaction temperature—were analyzed to …

A Study of Self-Healing Polymer Nanocomposites with Filler Effect
Abstract: Considering their versatility, polymers sometimes lack the barrier properties, mechanical strength, and thermal stability required for high-performance applications. The creation of polymer nanocomposites is an advanced solution to this restriction. To make these materials, nanoscale fillers like carbon nanotubes, graphene, silica, clay, and metal oxide nanoparticles are added to a polymer matrix in small amounts (typically 1–5% weight percentage). The nanoparticles’ incredibly high surface area-to-volume ratio, as well as their …

Self-healing Polymer Nanocomposites study using filler effect
Abstract: Polymers, while versatile, often lack the desired mechanical strength, thermal stability, or barrier properties for high-performance applications. This limitation is elegantly addressed by creating polymer nanocomposites. These materials are formed by incorporating small amounts (typically 1-5 wt%) of nanoscale fillers (e.g., carbon nanotubes, graphene, silica, clay, metal oxide nanoparticles) into a polymer matrix. The magic of nanocomposites lies in the incredibly high surface area-to-volume ratio of the nanoparticles and their …
