Novel and facile synthesis of silver nanoparticles using Albizia procera leaf extract for dye degradation and antibacterial applications.

This project is focuses on novel, cost effective and simple plant mediated synthesis of silver nanoparticles (Ag-NPs) using leaf extract of Albizia procera. The optical, structural and physical properties of green synthesized Ag-NPs have been investigated by UV-Visible spectroscopy, X-ray Diffraction (XRD) and Atomic Force Microscopy (AFM), respectively. Prepared Ag-NPs are spherical in shape and crystalline in nature with an average size of 6.

A review on green synthesis of silver nanoparticles and their applications.

Development of reliable and eco-accommodating methods for the synthesis of nanoparticles is a vital step in the field of nanotechnology. Silver nanoparticles are important because of their exceptional chemical, physical, and biological properties, and hence applications. In the last decade, numerous efforts were made to develop green methods of synthesis to avoid the hazardous byproducts.

Synthesis of Enantioenriched Pyrrolidines via Gold-Catalyzed Tandem Cycloisomerization/Hydrogenation of Chiral Homopropargyl Sulfonamides.

A novel gold-catalyzed tandem cycloisomerization/hydrogenation of chiral homopropargyl sulfonamides has been developed. Various enantioenriched pyrrolidines can be obtained in excellent yields and excellent enantioselectivities by combination of chiral tert-butylsulfinimine chemistry with gold catalysis. Importantly, this represents the first example of a pyrrolidine synthesis from homopropargyl sulfonamide.

Dietary vitamin E in White Leghorn layer breeder hens: a strategy to combat aflatoxin B1-induced damage.

Mycotoxins are unavoidable contaminants of animal and human feed and food respectively. This study was designed to investigate the protective activity of vitamin E (Vit E) in White Leghorn breeder hens and their progeny against aflatoxin B1 (AFB1)-induced damage. The results indicated a significant decrease in egg production and quality in the groups exposed to dietary AFB1.
