Teucrioside, 9′-decarboxyrosmarinic acid 4′-O-α-rhamnosyl-(1‴→6‴)-O-β-galactosyl-(1‴→4″)-Oα-rhamnoside is a natural phenolic compound. It has been isolated and identified from the genus Teucrium. Teucrium widely used in traditional medicine for its antioxidant, diuretic, antiulcer, antitumor, anti-inflammatory, antispasmodic antibacterial properties. Since silver nanoparticles have superior phy...
The present work shows the implementation of response surface methodology, fed by an experimental central composite design (CCD) to find conditions that allow maximizing inhibition microorganism Staphylococcus aureus with nanoparticles TiO2 silanized 3-aminopropyltriethoxysilane (APTES) and doped Ag. In addition, poly(lactic) acid composites were prepared these Ag/TiO2 aim confer their antimicr...
a-Silica encapsulated silver nanowires (diameter of 25 +/- 5 nm, average length of 10 mum) have been synthesized by reacting (Me3Si)4Si with AgNO3 in nearly quantitative yield. Formation of the a-silica shell layer (1-3 nm) in situ appears to be one of the most important factors in this simple process.
Structural phase transition in AgN03 at high temperature is simulated by molecular dynamics. The simulations are based on the potentials calculated from the Gordon-Kim modified electron-gas formalism extended to molecular ionic crystals. AgN03 transforms into rhombohedral structure at high temperature and the phase transition is associated with the rotations of the N03 ions and displacements of...
AgNO3-impregnated prep-TLC purification of the wax extract of Cocos nucifera allowed the isolation and identification of skimmiwallinin as an additional skimmiwallinol derivative from the cuticular wax of coconut palms. Identification was based on the comparison of its spectroscopic data with those reported in the literature.
Article history: Received on: 24/02/2016 Revised on: 12/04/2016 Accepted on: 07/05/2016 Available online: 28/06/2016 Silver nanoparticles (AgNPs) have potential antimicrobial activity against bacteria and fungi. The synthesis of AgNPs have been reported using several chemical and physical methods which are not friendly environment. Therefore, our technique has focused on the synthesis of AgNPs ...
The design and synthesis of shape-directed nanoscale noble metal particles have attracted much attention due to their enhanced catalytic properties and the opportunities to study fundamental aspects of nanoscale systems. As such, numerous methods have been developed to synthesize crystals with tunable shapes, sizes, and facets by adding foreign species that promote or restrict growth on specifi...
