ZnO nanorod arrays were synthesized by chemical bath deposition. After heat treatment in hydrogen or air, Ag nanoparticles were deposited on ZnO nanorod arrays by photo-reduction method. The size of Ag nanoparticles as well as the surface morphology, structure, composition, and optical property of ZnO nanorod arrays before and after the deposition of Ag nanoparticles were characterized by SEM, ...
The Performance of electric vehicle IGPT Pin fin heat sink can be measured by the temperature field and the fluid pressure and other parameters. In order to improve the cooling effect of Pin fin heat sink, diameter, length and distance of the fin was optimized combination. The relationship between pressure drop of the water inlet, outlet and pin fin parameters was analyzed and calculated. It wa...
in this study, binding ability of lactobacillus rhamnosus lgg to aflatoxin of pistachio was investigated. results indicate that the bacterium has aflatoxin surface binding ability of 35% (with initial concentration of 10 ppb aflatoxin) in exponential phase. acid and heat treatment increase this ability to 85%. in the second concentration of aflatoxin (20 ppb), this binding ability for viable ce...
the plain carbon steel “ck45” has relatively well mechanical and metallurgical properties and low cost. the purpose of this research was the property evaluation of this steel on abrasive wear and impact for using in plows and other tillage tools. tillage tool should resist in abrasive wear and impact simultaneously. several heat treatments were done on specimens of this steel. a standard test d...
Incubation in most avian species involves transferring heat from parent to egg through a highly vascularized brood patch. Some birds, however, do not develop a brood patch. Unusual among birds, these species hold their eggs under the webs of their feet, but the role of the feet in heat transfer is uncertain. Often the webs are positioned between the feathered abdomen and the egg during incubati...
Since the mean characteristic of nucleate boiling is bubble formation and collapse near the heating surface, in this study attempts have been made to investigate heat transfer effects due to the bubbles ebullition and collapse cycle. All possible heat transfer mechanisms are studied qualitatively and quantitatively. For quantitative calculation of the heat transfer portion by each of the introd...
Current work targeted to predicate parametric relationship between aggregate and individual property of a protein. In this approach, we considered individual property of a protein as its Surface Roughness Index (SRI) which was shown to have potential to classify SCOP protein families. The bulk property was however considered as Intensity Level based Multi-fractal Dimension (ILMFD) of ordinary m...
Nanofluids are the heat transfer fluids having remarkable thermal properties. The paper presents the experimental analysis of thermal conductivity, density, specific heat and viscosity of multiwalled carbon nanoparticles dispersed in water at various temperatures and particle concentrations. To examine the forced convection heat transfer of Multiwalled Carbon Nanotubes (MWCNT)-water nanofluid, ...
