We report the direct and self-selective synthesis of Ag nanowires (NWs) on graphene patterns through a modified citrate reduction reaction approach. High-density NWs were selectively formed only on the graphene areas, whereas NWs were not synthesized on the SiO2/Si and glass substrates. The size and density of the Ag NWs gradually increased with increasing reaction time and AgNO3 concentration....

This study focuses on the efficacy of silver nitrate (AgNO3) as a coating agent used to preserve papers against microbial deterioration. To this end, in vitro cytotoxicity AgNO3 was assessed two normal cell lines, WI-38 and HFB-4, detect safe dose that can be agent, which 80 µg mL−1. Bacillus subtilis B3 Penicillium chrysogenum F9 were selected high deteriorating microbes, previously isolated f...

in this research oxidation kinetic panceuo.s (p.s) by s2o8-2 at the presence of agno3 ascatalyst was studied.the method was spectrophotometer following absorption spectrum (p.s) inwave length of 518 nm. after improving the condition such as ph, p.s concentration, k2s2o8concentration, ionic strength, temperature, rate constant, activation energy, constant frequency,order reaction and thermo dyna...

The quinoline urea derivatives 1,3-di(quinolin-5-yl)urea (DQ5U), 1-phenyl-3-(quinolin-6-yl)urea (PQ6U), 1-(isoquinolin-5-yl)-3-phenylurea (PiQ5U) and 1-phenyl-3-(3,5-bis(pyrid-2-yl)-1,2,4-triazol-4-yl)urea (PPT4U) have been synthesised and structurally characterized by powder and single crystal X-ray diffraction. Their gelator behaviour in the formation of Ag-complexes has been explored. Compou...

The aim of this study is to determine some phytochemical contents, to synthesize silver nanoparticles AgNPs using Cuminum cyminum (C. cyminum) leaf extract, to study the effects of different conditions on the rate of synthesis, and to evaluate their antibaterial and antifungal activities. AgNPs were synthesized using C. cyminum leaf extract as bioreducer agent and aqueous silver nitrate solutio...

Silver nanoparticles were prepared by using alkali treated maize starch which plays a dual role as reducer for AgNO3 and stabilizer for the produced AgNPs. The redox reaction which takes a place between AgNO3 and alkali treated starch was followed up and controlled in order to obtain spherical shaped silver nanoparticles with mean size 4-6 nm. The redox potentials confirmed the principle role o...

______________________________________________________________________________ In this paper the conductometric titration of propranolol hydrochloride in pharmaceutical formulations using silver nitrate as titrant is proposed. The method was based on the formation of an insoluble salt (AgCl(s)) between the chloride of propranolol hydrochloride molecule and Ag(I) ions of the titrant AgNO3. The e...
