Abstract:

Green chemistry aims to minimize the environmental impact of chemical processes by utilizing sustainable and eco-friendly methodologies. Micelles, self-assembled structures formed by surfactants in aqueous solutions, have emerged as an effective reaction medium for organic transformations due to their inexpensive and environmentally benign nature. This review covers the designer reusable surfactants (viz., Brij-35, Coolade, SDS, Triton X-100, TPGS-750-M, NIPAAm-b-PEG, etc.) and their use in aqueous micelles to facilitate a wide range of organic transformations for the carbon-carbon and carbon-

Abstract:

The reaction of sodium selenite source with various extracted orange covers in an acidic suspension during ambient circumstances has been devised as a simple sol gel technique to generate selenium nanoparticles. The selenium nanoparticles were stabilized with polyvinyl alcohol. A high-speed centrifuge can be used to isolate the nanoparticles from their sol, and a sonicator can be used to redisperse them in an aqueous media. The produced selenium nanoparticles were characterized using UV-visible optical absorption spectroscopy and X-ray diffraction methods.

Abstract:

AbstractColloidal silver nanoparticles were prepared by rapid green synthesis using different tannin sources as reducing agent viz. chestnut (CN), mangrove (MG) and quebracho (QB). The aqueous silver ions when exposed to CN, MG and QB tannins were reduced which resulted in formation of silver nanoparticles. The resultant silver nanoparticles were characterized using UV-Visible, X-ray diffraction (XRD), scanning electron microscopy (SEM/EDX), and transmission electron microscopy (TEM) techniques. Furthermore, the possible mechanism of nanoparticles synthesis was also derived using FT-IR analysi

Aspergillus species are causative agents of invasive fungal infections in immunocompromised patients and associated with pulmonary diseases, mycotic diseases, keratitis mycotic keratitis, otomycosis and nasal sinusitis. At least 30 Aspergillus species are associated with human diseases. Aspergillus niger is a member of the genus Aspergillus which includes a set of fungi that are generally considered asexual, although perfect forms. Aspergillus flavus is a fungus grows by producing thin thread like branched hyphae. Aspergillus flavus is a filamentous mould.A. fumigatus is characterized by green

Abstract:

The synthesis of gold nanoparticles (Au-NPs) is performed by the reduction of aqueous gold metal ions in contact with the aqueous peel extract of plant,Garcinia mangostana(G. mangostana). An absorption peak of the gold nanoparticles is observed at the range of 540–550 nm using UV-visible spectroscopy. All the diffraction peaks at 2θ= 38.48°, 44.85°, 66.05°, and 78.00° that index to (111), (200), (220), and (311) planes confirm the successful synthesis of Au-NPs. Mostly spherical shape particles with size range of 32.96 ± 5.25 nm are measured using transmission electron microscopy (TEM). From t

Abstract:

Present work describes the synthesis of 4-aryl substituted 3,4-dihydropyrimidinones (DHPMs) using aqueous extract of pericarp of Sapindus trifoliatus fruit as a green catalyst. The reaction is a one-pot reaction, similar to classical Biginelli reaction employing an aromatic aldehyde, urea and active methylene compound (ethyl acetoacetate) as substrates. Desired DHPMs were yielded within 2 h at room temperature. The key advantage of the present strategy was its low dependence on organic solvents as green synthesis.
