The exponential rise in world population, the depletion of fossil fuels resources, and the severe environmental consequence of petroleum-based fuels have initiated an enormous search for renewable fuel as a substitute for petroleum fuel. In line with that, this study reports the use of a calcium oxide catalyst derived from waste guinea fowl eggshel...

... concurs with the essence of the transesterification of oil or fats to reduce the density for proper application in the existing engines. Table 2 compared some biodiesel properties; density, acid value, and free fatty acid, with that of ASTM D6751 and ASTM D975 standards, as well as the percentage conversion in this study with the previous study. The properties of the biodiesel in the present study agreed well with those of the standard and are even better than some studies in the literature. ...Similar publications
Intracanal medicaments are an important adjunct to the effective disinfection of the root canal system. However, conventional intracanal medicaments do not provide adequate protection against Enterococcus faecalis, which is the organism of interest in many cases of root canal failures. This study aimed to evaluate the influence of biosynthesized ca...

... This may be caused by two reasons. Firstly, the main component of calcined TOS is calcium oxide, which has hygroscopic properties [40], leading to an increase in the water absorption of the blend material. Secondly, there may be interface defects between TOS and LDPE, which would increase the space for water storage. ...
This research delves into the impact of incorporating thermally treated oyster shell powder (TOS), a biowaste filler, into low-density polyethylene (LDPE) to develop a LDPE/TOS blend, aiming at enhancing food packaging materials. The LDPE/TOS blend portrays advantageous characteristics such as augmented mechanical strength, thermostability, crystallinity, water absorption, and improved hydrophobicity with TOS content up to 50%. Microstructure analysis reveals a transition from a sparse to a more interconnected structure, contributing to the amplified tensile strength. The blend demonstrates increased barrier properties against water vapor transmission, which is attributed to elongated diffusion paths induced by the TOS particles. Application of the blend material in vegetable preservation trials manifested a substantial reduction in water loss compared to pure LDPE or no packaging. This biowaste-based blend film extends the shelf-life of chicken significantly when compared to that of pure LDPE. Importantly, the LDPE/TOS blend exhibits excellent antibacterial properties against both Escherichia coli and Staphylococcus aureus.
