This is the first report on the synthesis of superstructures of MnCO3 and MnCO3–rGO using plant extracts via low-temperature hydrothermal method. The synthesized material shows good lithium-ion battery performance and can be used for the detection of dopamine.

Various plant extracts have currently been used in the bioproduction of nanoparticles with enormous applications. In this study, Rauvol a tetraphylla ower extracts were employed to obtain silver nanoparticles (Ag NPs) in bioproduction. The biologically produced nanoparticles were characterized by XRD, FTIR, UV-Vis, BET, SEM, EDXA, and TEM analyses. Phytochemical screening of the Rauvol a tetraphylla ower extracts indicated presence of 9 di erent constituents. Bioreduction of Ag NPs by phytochemicals was revealed by FTIR analysis. The elemental composition of Ag NPs was reported by spectral EDXA. The Ag NPs exhibited anti-bacterial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella aerogenes, and Escherichia coli; anti-fungal activity against Penicillium citrinum and Aspergillus avus; and antimitotic activity. The response of amines in formic acid in the presence of an Ag NPs catalyst in dissolvable free condition provided high yielded convention for the N-formylation to shape the comparing formamide derivatives. N-fromylation had the characteristics of incite recyclability, clean strategy, environmental friendliness under milder response conditions, and straightforward work-up with brilliant yield of the coveted items.

NiFe2O4 nanoparticles (NPs) have attracted great attention in vast fields such as sodium-ion batteries (NaIBs), bio-sensing, and catalysis. In this direction, herein, NiFe2O4 NPs were synthesized by simple co-precipitation method...
