Exploration of agricultural residue ash as a solid green heterogeneous base catalyst for biodiesel production

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.

Nanostructured Lipid Carriers for Improved Delivery of Therapeutics via the Oral Route

Journal of Nanotechnology, Volume 2023, Issue 1, 2023., 2023
Drug delivery via the oral route has always been challenging for poorly soluble drugs. Acid‐induced hydrolysis, enzymatic degradation, and poor mucosal absorbency remain the primary hiccups for effective oral delivery of medications. With the advent of nanotechnology, nanostructured lipid carriers (NLCs) have emerged as a promising delivery carrier ...

Potential Heterogeneous Catalysts from Three Biogenic Residues toward Sustainable Biodiesel Production: Synthesis and Characterization

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 ...
