Performance Evaluation of Rice Bran Oil—Waste Cooking Oil Binary Blend‐Based Biodiesel With Normal Diesel in CI Engine

Engineering Reports, Volume 8, Issue 2, February 2026.
This study evaluates the performance and emissions of CI engines using biodiesel blends derived from rice bran and waste cooking oil, revealing that a 30% biodiesel blend significantly reduces emissions, while a 70% blend affects specific engine parameters. ABSTRACT This research investigates the performance, combustion, and emission characteristics of

Engineering Biomimetic Nanoparticle Performance Through Fabrication Method Selection: Turbulent Jet Mixing, Microfluidics, and Extrusion

Small Methods, Volume 10, Issue 3, 9 February 2026.
Biomimetic nanoparticles (BNPs) combine liposomal biocompatibility with cell‐mimicking functions for targeted delivery. This study compares turbulent jet mixing, microfluidic mixing, and extrusion for BNP fabrication. Characterization, proteomics, and in vitro assays show that turbulent jet and microfluidic mixing produce stable, protein‐enriched ...
