polyaniline and polyamide (nylon 6,6) nanocomposites with silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of ag salt nano particles of silver (nps) were symthesieedby controlled reduction of ag+ ions kith sodium borohydride at room temperature. nylon 6,6 wax loaded withag nanoparfieles by erdrapment of ag+ ions into the polymer network, followed by red...

The present study was aimed at evaluating the fluorescence property, sporicidal potency against Bacillus and Clostridium endospores, and surface disinfecting ability of biogenic nano silver. The nano silver was synthesized using an actinobacterial cell-filtrate. The fluorescence property as well as imaging facilitator potency of this nano silver was verified adopting spectrofluorometer along wi...

Tumor growth is characterized by uncontrolled cell division. For centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional Iranian and Pakistani medicine for the treatment of melanoma and breast cancer. We have found that these nanocomposite particles are similar to silver nanoparticles (AgNps) in size and shape and that there are so differenc...

abstract alstroemeria is one of the most important cut flowers in the world which is multiplicated by rhizome explants in in vitro conditions . the major problem in using rhizome explants is fungal and bacterial contamination which inhibit the preparation of strill explants. therefor in this experiment, the effect of disinfecting compounds like sodium hypochlorite, mercury chloride, nano silver...

An experiment was conducted in CRD, which two factors were evaluated viz., different wrapping materials and levels of Silver Nano Particles taken to observe the effect shelf life cut rose. Different SNP at 10,20,30, 40 ppm along with such as- Butter paper, LDPE, aluminium foil newspaper as control used refrigerated condition. Present study concluded that roses had longest 30 NS (Nano Silver) BC...

Nano packaging is currently one of the most important topics in food packaging technologies. The aim of the application of this technology in food packaging is increasing shelf life of foods by preventing internal and external corruption and microbial contaminations. Use of silver nanoparticles in food packaging has recently attracted much attention. The aim of this study was to investigate the...

According to the unique properties and many applications of nano silver powder, it was prepared from acid leaching tail solution. The low value residual gold and silver ions were occurred with fellow heavy metals as pollutants (Fe2+, Cu 2+ and Zn2+) in acid leaching tail solution in Mouteh gold mine in Iran. Preparation of nano silver particles was achieved in two steps: first, by addition of a...
