Metal nanoparticles have gained significant interest in the past decade because of their unique physio-chemical properties which has a potential to be used in a wide range of applications. Recent efforts have gained success in synthesising nanoparticles with excellent shape and size control; however they are largely restricted to chemical methods. There is an increasing focus on eco-friendly ‘g...

Hans Ris proposed in 1961 that chloroplasts might be highly derived endosymbiotic microorganisms, originally related to blue-green algae. Evidence from 1966 and earlier is reviewed to test this proposal. Elegant experiments using the unique genetic system offered by Oenothera (the evening primroses) clearly show that plastids carry heritable characters not under nuclear control. Two or even thr...

an atom-efficient, eco-friendly, solvent-free, high yielding, multicomponent green strategy to synthesize triazolo[1,2-a]indazole-triones derivatives by the one-pot condensation of aldehyde, dimedone, and phenyl urazole is presented. a series of different substituted aromatic aldehydes including either electron-withdrawing or electron-donating groups used in this reaction participated well and ...

An atom-efficient, eco-friendly, solvent-free, high yielding, multicomponent green strategy to synthesize triazolo[1,2-a]indazole-triones derivatives by the one-pot condensation of aldehyde, dimedone, and phenyl urazole under microwave Irradiationis presented. Reactions catalyzed by A novel nanomagnetic organic-inorganic hybrid catalyst (Fe@Si-Gu-Prs) was prepared by the chemical anchoring of P...

In this study, green or eco-friendly synthesis of TiO2 nanoparticles (NPs) was performed by using the aqueous extract of Acanthophyllum laxiusculum. The plant genus Acanthophyllumis one of the natural sources rich in nonionic surface active agents known as saponins. Sol-gel method as one of the most common techniques widely used in nano-field was applied to synthesize the titanium dioxide nanop...

Bio-directed synthesis of nanoparticles is an interesting field of rapid advancement for biologists,chemists and materials scientists, especially in light of efforts to find out green methods of inorganicmaterial synthesis. In the present study, green synthesis of platinum nanoparticles (PtNPs) using sheepmilk is reported for the first time. By adjusti...
