In recent decades, the focus of science and industry has been concentrated on production of metalnanoparticles (NPs). In this study, the biosynthesis of silver NPs by using Tragopogon buphthalmoides(Tragopogon b.) plant was investigated. Various effective parameters on the synthesis such as pH, extractvolume, concentration of silver nitrate, temperature and reaction time were ...

quinazolinone derivatives are essential units in a wide range of relevant pharmacophores with a broad spectrum of abilities. due to their wide range of pharmacological and therapeutic activities including anticonvulsant, anti-inflammatory, hypolipidemic, anticancer, and anti-ulcer, the synthesis of quinazolinone moieties as a privileged class of fused heterocyclic compounds, have received much ...

     In a hydrothermal route devoted for synthesis of Ca10(PO4)6(OH)2 (HA) nanostructures, morphology can be controlled by experimental condition to form magical HA or nanostructured nanoparticles. In an intermediate condition, a novel nanostructure namely rose-like bundle of HA rod-likes was found, which is different from known HA nanostructures. The...

[2,2'-Bipyridine]-1,1'-diium tricyanomethanide {[2,2'-BPyH][C(CN)3]2} as a bifunctional nanostructured ionic liquid catalyst (0.5 mol%) was used for the synthesis of 3,4-dihydropyrano[c]chromenes (14 examples) under solvent-free condition at room temperature in high yield (82-91%) and short reaction time. In addition, the described ionic liquid catalyst was also applied for the synthesis of bis...
