Development and Characterization of a 3D Printed Cocoa Bean Shell Filled Recycled Polypropylene for Sustainable Composites
(Multidisciplinary Digital Publishing Institute - MDPI, 2021)
Natural filler-based composites are an environmentally friendly and potentially sustainable alternative to synthetic or plastic counterparts. Recycling polymers and using agro-industrial wastes are measures that help to ...
Influence of biodiesel blends produced in Colombia on a Diesel engine
(Universiti Malaysai Pahang, 2021)
Diesel engines have dominated the heavy duty and passenger vehicle market in the
past 30 years. Consequently, the oil-derived fuels demand and the amount of pollutant emissions
have witnessed exponential growth during ...
Geometric design optimization of a Savonius wind turbine
(ElSevier, 2022)
Savonius vertical-axis wind turbines are becoming an outstanding alternative for small-scale power generation mainly due to their simple design, high self-starting performance at low wind speeds, omnidirectional capability, ...
