Although diesel engine emissions, which can pose serious risks to the environment and human health, can be reduced with biodiesel/diesel fuel blends, combining diesel fuel with an oxidation catalyst with a sizable oxygen storage capacity can more effectively reduce emissions from diesel engines. In this study, Fe–Ni–TiO2/Activated Carbon (AC) catalyst was produced and used as an oxidation catalyst. Experimental studies were performed on a four-stroke diesel engine by adding at numerous concentrations (0–50–100 ppm) Fe–Ni–TiO2/AC nanoparticles (NP) to the Palm Oil biodiesel (PO)-diesel fuel blend. Optimum conditions were determined by modelling the obtained data in response surface methodology (RSM). The Fe–Ni–TiO2/AC catalyst outcomes in a considerable decrease in hydrocarbon (HC), nitrogen oxides (NOx), carbon monoxide (CO), and smoke emissions. Optimization outcomes pointed out that the ideal diesel engine running requirements were determined to be 1750 W engine load, 100 ppm the NP amount, and 30% the PO ratio. Responses for these optimum conditions for Brake Specific Fuel Consumption (BSFC), Brake Thermal Efficiency (BTHE), CO, HC, NOx, and smoke were determined as 999.06 g/kWh, 27.07%, 0.032%, 40.63 ppm, 818.18 ppm, and 4.26%, respectively. The R2 values showed that the result obtained from the created model was in good agreement with the experimental results.

“…Homogeneous catalysts present high conversions, but they cannot be reused. In addition, saponification occurs in the presence of free fatty acids, generating residues and increasing the cost of the process (Helmi et al, 2022;Maheswari et al, 2022). According to Lôbo et al (2009), homogeneous alkaline catalysts have high conversion efficiency, with NaOH and KOH being the most used due to their low cost.…”

Currently, concern about the burning of fossil fuels and the consequences for the planet has increased and become the agenda of discussions at global levels. In this sense, biofuels are an important alternative, and this article seeks to review the literature on the use of microalgae as raw material for the manufacture of biodiesel, the transesterification process as a conversion method, the technologies used to optimize this process, the characteristics of biodiesel that are required by Brazilian legislation, and the challenges for production. Brazil has a very large potential for the production of these biofuels but their production on a large scale still requires further studies so that it can be part of the country's energy matrix, including in the agro-industrial sector.

“…Clinoptilolite (CLN) is a widely used natural zeolite with good biocompatibility. It has a three-dimensional crystal porous structure with a general formula of (Na, K) 6 Al 6 Si 30 O 72 •20H 2 O, where the Si/Al ratio can range from 4.0 to 5.3 ( Helmi et al, 2022 ). It is commonly utilized for organism detoxification, medicine delivery, and biosensor creation.…”

As an important worldwide medical issue, bone defect exhibits a variety of physical and psychological consequences on sufferers. Some features of clinical treatments including bone grafting and limb shortening are not satisfactory. Recently, bone tissue engineering has been considered as the most effective approach to dealing with the issue of bone deformities. Meanwhile, a variety of biomaterials have been rationally designed and created for the bone regeneration and tissue repairing. Among all these admirable biomaterials for bone remodeling, zeolite-based materials can serve as efficient scaffold candidates with excellent osteo-inductivity. In addition, the porous nature and high biocompatibility of zeolites endow them with the ability as ideal substrates for cell adhesion and proliferation. More importantly, zeolites are investigated as potential coating materials for implants because they have been proven to increase osteo-conductivity and aid in local elastic modeling. Last but not least, zeolites can also be used to treat bone disorders and act as dietary supplements during the practical applications. Accordingly, numerous benefits of zeolite prompt us to summarize their recent biomedical progress including but not limited to the distinguishing characteristics, broad classifications, as well as promising usages in bone tissue engineering.
