“…Antibacterial activity of the MoO 3 NPs against a Gram-positive [23] S. epidermidis and a Gram-negative E. aerogenes bacterial pathogens was investigated by measuring zone of inhibition (ZOI), colony-forming unit (CFU), and optical density (OD). Antibacterial activity of MoO 3 NPs was also compared with standard antibiotics.…”

Objective: The objective of this study was to synthesize the molybdenum oxide nanoparticles (NPs) by employing wet chemical method and investigation of their antibacterial properties against pathogenic bacteria. Methods: Molybdenum trioxide (MoO3) NPs were synthesized using an eco-friendly wet chemical sol–gel technique. The synthesized MoO3 NPs were characterized using X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy, and ultraviolet-visible spectroscopic techniques to confirm the obtained product, size shape, morphology, functional groups, and absorption spectra, respectively. The size of the MoO3 NPs was found to be 41 nm. The antibacterial activity of these metal NPs was investigated on Staphylococcus epidermidis and Enterobacter aerogenes by measuring the zone of inhibition and colony-forming units on solid medium and by measuring the optical density of the culture solution. Antibacterial activity of MoO3 NPs was also compared with well-known standard antibiotics. Results: The antibacterial activities of molybdenum oxide NPs possessing size 41 nm were compared with standard antibiotics such as oxacillin, cotrimoxazole, erythromycin, clindamycin, chloramphenicol, and tetracycline. It was found that all of these antibiotics were effective against Staphylococcus epidermidis while Enterobacter aerogenes was resistant to oxacillin, co-trimoxazole and clindamycin, whereas the MoO3 nanoparticles were found to be effective against both of these bacterial pathogens. Conclusion: Inorganic antimicrobial agents have advantages over organic antimicrobial agents due to their stability, preparation methods, and their ability to prevent bacteria to develop multidrug resistant. It was observed that MoO3 nanoparticles (NPs) possess good antibacterial properties; therefore, these can be used in pharmaceutical industries and provide a path for further research regarding the toxicity study for its use in human being.

In this study, Co3O4 nanocatalysts were constructed in environmentally appropriate conditions using controlled, effective, and facile microwave method. The final nanostructures were characterized by SEM, XRD, and TEM analyses. The products had a small size distribution, homogeneous morphology, and crystallographic structures associated with the formation of Co3O4 nanostructures. Moreover, EDS mapping analysis confirmed the existence of Co and O elements in the final structure, and the magnetic properties of the samples were investigated by VSM. The application of this nanostructure in a catalytic process was further examined, and the results suggested that it could be used as a novel candidate for the synthesis of arylidene barbituric and Meldrum,s acid through Knoevenagel condensation of aldehydes by barbituric and Meldrum,s acid in aqueous media. The high yield of these nanocatalysts would be justified by the nature of the nanostructure as well as the experimental procedure developed in this study, which affected the physicochemical features of the products.

Two hitherto unknown magnetic nanoparticles were prepared through the immobilization of Dysprosium (Dy) and Praseodymium (Pr) Complexes on the surface of CoFe2O4, using commercially available or easily accessible materials under green conditions. They were fully characterized, using, FT‐IR, SEM, EDX, ICP‐OES, XRD and TGA techniques. Photocatalytic activity of these nanocomposites were successfully examined in the high yielding synthesis of pyrano[2,3‐d]pyrimidines, via MCR, involving, barbituric acid, malononitrile and differently substituted benzaldehydes in the UV region (250 nm) at room temperature. The above‐mentioned photocatalysts showed excellent recoverability and reusability under the optimal reaction conditions.
