Engineering Reports, Volume 5, Issue 1, January 2023., 2023 Transesterification of vegetable oils with homogeneous catalyst for biodiesel synthesis is considered to have a promising future, but it is nonrenewable and hazardous. High production cost, in terms of feedstock oil and catalyst acquisition is one of the major challenges facing the global commercialization of biodiesel.

ChemistrySelect, Volume 7, Issue 48, December 27, 2022., 2022 Heterogeneous base catalysts were synthesized from the periwinkle shell, melon seed husk, and locust bean pod husk via thermal decomposition at 800°C. The catalysts were characterized by their elemental, structural, and functional compositions. The three catalysts gave appreciable biodiesel yields and good stability throughout the transesterification ...

Optimization on the Mechanical Properties of Aluminium 8079 Composite Materials Reinforced with PSA
Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 AA 8079 with variable percentages of peanut shell ash (PSA) was created by stir casting (2.5 percent, 5 percent, 7.5 percent, 10 percent, 12.5 percent, and 15 percent). Compared some of the physical and mechanical properties of the composite material were to the alloy matrix alloy (density; porosity percentage; hardness; wear index; tensile strength ...

Advances in Materials Science and Engineering, Volume 2021, Issue 1, 2021., 2021 Volume change in expansive soils is a problem encountered in earth work around the world. This is prominent with hydraulically bound structures or foundations subjected to prolonged moisture exposure. This behavior of clayey used as subgrade, foundation, landfill, or backfill materials causes undesirable structural functionality and failures.

International Journal of Mechanical and Civil Engineering, 2022 Periwinkle shellfish can be found in abundance in the Niger Delta's wetlands. Periwinkle shells are frequently piled in open fields and landfills, resulting in pollution and the development of disease-carrying organisms. Attempts have been made to employ periwinkle shell ash (PSA) as recycled materials in cement-based products in order to manage ...
