Fabrication of nano-structured materials has been developed by performing pulsed laser ablation of copper, gold, and silver plates in supercritical CO2. The metal nano-structured particles were successfully generated with allowing the selective generation of clusters. Laser ablation was performed with an excitation wavelength of 532 nm. On the basis of the experimental result, both surface of a...

Preparation of size controlled nano-particles of silver catalyst on carbon substrate from e-waste has been investigated. Chemical route was developed by extraction of the metals available in nitric acid followed by treatment with hydrofluoric acid. Silver metal particles deposited with an average size 4-10nm. A stabilizer concentration of 10-40g/l was used. The average size of the prepared silv...

The field of nanotechnology is one of the most active areas of research in modern materials science. New applications of nanoparticles and nanomaterials are emerging rapidly. Nanocrystalline silver particles have found tremendous applications in the field of high sensitivity biomolecular detection and diagnostics, antimicrobials and therapeutics, Catalysis and micro-electronics. The use of nano...

today, rocky monuments are being exposed to different physical, chemical and biological factors and therefore going to be ruined. one of physical destructive factors is growing of fungus and lichens on the rocks. this research aims to make use of silver nano-particles produced through microbial method in order to prevent growth and progression of fungus detached from rocky surfaces in meymand h...

this study was conducted to evaluate the effect of preservative solutions on vase life, number of bacteria in the end of stem and in vase solution of cut gerbera 'double dutch' and 'red explotion'. cut flowers were pulse-treated with nano-silver (2, 4, 6, 8 or 10 mg l-1) and thymol (12.5, 25, 50, 75 or 100 mg l-1) +5 % sucrose. experiment was conducted in completely randomized design with 5 rep...

Ternary nano-biocomposite films based on poly(lactic acid) (PLA) with modified cellulose nanocrystals (s-CNC) and synthesized silver nanoparticles (Ag) have been prepared and characterized. The functionalization of the CNC surface with an acid phosphate ester of ethoxylated nonylphenol favoured its dispersion in the PLA matrix. The positive effects of the addition of cellulose and silver on the...

INTEGRATION OF Ag2Ga NANONEEDLES ON BATCH FABRICATED MICRO-GRIPPERS FOR MATERIAL PROPERTY MEASUREMENT PengXu March 22, 2011 In this thesis self-assembled growth of Ag2Ga nano-needles on batch fabricated micro-grippers are reported. The room temperature growth of Ag2Ga nano-needles have been recently developed as stylus for Atomic Force Microscopy (AFM). Integration of such nano-needles onto bat...

This study utilizes silver nano-fluid filled flat heat pipe. It is aimed at effect of various concentrations on flat heat pipe thermal performance by air-cooling testing equipment. The particles used in these experiments were silver particles 35 nm in size. The base working fluid was pure-water. Nano-fluids were prepared using a two-step method. In the experiment, the thickness and length of th...

Poly(o-anisidine) molybdophosphate was expediently obtained by sol-gel mixing of Poly(o-anisidine) into the inorganic matrices of molybdophosphate, which was allowed to react with silver nitrate to the formation of poly(o-anisidine) molybdophosphate embedded silver nano composite. The composite was characterized by Fourier Transform Infrared Spectroscopy, X-ray powder diffraction, UV-Vis Spectr...
