        MgO@SiO2 nanocomposite was synthesized using mechanochemical method and its formation was confirmed by FTIR and Uv-visible spectroscopic techniques. The antibacterial effect of MgO@SiO2 nanocomposite was carriedout on bacterial isolates; gram-positive bacteria (Bacillus subtilis, Klebsiella pneunoniae) and gram-negative bacteria (Pseudomonas aeruginasa, Escherichia coli, and Salmonella typhi) using Agar well diffusion method. The results showed that MgO@SiO2 nanocomposite can find application as antibiotics against the investigated microbes.

        Ni / SiO2 heterogeneous nano catalyst was synthesized and characterized using different analytical tools including FT-IR, UV spectrophotometer, SEM equipped with an energy dispersive X-ray spectrometer (EDX), and XRD. The synthesized catalyst was used in the transesterification of methyl ester produced from mahogany seed oil. The reaction conditions for the transesterification process were optimized. The yield of 85% was achieved when the reaction was carried using Ni / SiO2 with concentration of 1.5% wt, volume ratio of methanol to oil of 5:1, reaction temperature of 60 °C, and a reaction time of 120 min. The Ni / SiO2 nano catalyst was regenerated from the mixture and was reused for various circles by applying the optimum conditions obtained during the present study. The results showed that the methyl ester yield decreased exponentially by increasing the cycle number when the regenerated catalyst was used. However, good conversion (>72%) was obtained up to the 4th cycles. It could be concluded that Ni / SiO2 nano catalyst is catalytically active and may serve as a potential catalyst for biodiesel production. Manuscript profile
