Computational study plays an important role to discover the potential of the bio-inspired nano scale molecular devices. Density Functional Theory (DFT) is one of the popular methods to calculate the properties of the molecules which can not be possible with ab initio process, preferably for transition metals. This method is important for electronic structure calculation […]
Metal oxide nanoparticles are capable of successfully inhibiting bacterial strains. Among the several transition metal atoms, iron (Fe) looks to be a viable dopant since iron oxide has been used a lot in biomedical research due to its biocompatibility and magnetic properties. In order to boost its antibacterial activity and facilitate the entry of nanoparticles into […]
Recently, the synthesis of metal nanocrystallites using plant extracts has received much attention due to its low cost and compatibility with the environment. In this research, copper nanocrystallites were synthesized using hawthorn extract. The formation of copper nanocrystallites was observed by changing the color of the solution. Synthesized copper nanocrystallites were investigated by techniques such […]
Cobalt vanadate (Co3V2O8) nanoparticles were prepared by a hydrothermal process using ammonia metavanadate and cobalt nitrate as precursors and calcined at 450 °C to obtain pure Co3V2O8 nanoparticles. The sample was characterized by scanning electron microscopy, X-ray diffraction, Fourier transform infrared, and UV-visible diffuse reflectance spectroscopy. The characterization analysis confirmed variations in the structure, shape, […]
Euphorbia helioscopia, a traditional medicinal herb, possesses various pharmaceutical applications for human diseases. In the present study, the ethanol and hexane extracts of E. helioscopia leaves were subjected to phytochemical screening to identify the presence of secondary metabolites. The concentrations of alkaloids, phenols, and flavonoids were determined quantitatively to evaluate the medicinal properties of the […]
This research used an oven and spray drying method to dry nanofibrillated cellulose (NFC) and evaluates its effect on polylactic acid (PLA) nanocomposite properties. As shown by atomic force microscopy (AFM), the average size of nanocellulose in the spray-dried sample (NCSD) was 84-96 nm. However, the average size of nanocellulose obtained from oven drying was […]
Rapid augmentation in the prevalence of multidrug-resistant (MDR) Staphylococcus aureus is a worldwide threat. Advising newer antibiotics may fail to reduce the chances of the emergence of newer drug-resistant Staphylococcus aureus. Very little shreds of evidence can be found to treat clinical MDR Staphylococcus aureus with biogenic silver nanoparticles (AgNPs) in West Bengal. To prepare […]
Nickel oxide (NiO) and cobalt doped Nickel oxide (Co-NiO) nanoparticles were successfully synthesized by cost effective, environmentally friendly, and scalable eco-precipitation method. The prepared nanoparticles were investigated by X-ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive X-ray analysis (EDAX), Fourier Transform Infrared Spectroscopy (FTIR), Optical spectroscopy (UV) and Cyclic voltammetric (CV). The structural characterization […]
