friction stir processing was applied for fabricating an aluminum alloy based hybrid nano composite reinforced with nano sized al2o3 and micro sized graphite particles. a mixture of al2o3 and graphite particles was packed into a groove with 1 mm width and 4.5 mm depth, which had been cut in 5083 aluminum plate of 10 mm thick. packed groove was subjected to friction stir processing in order to im...

in order to investigate the gas separation ability of a column packed with nanozeolitic material, nano nay zeolite was synthesized and granulated. these uniform granules packed in a chromatographic column were utilized for separation of xe and kr under various operating conditions. with regards to the response peaks obtained from trace injections of xe and kr into the column, the first and seco...

Study of biophysical interactions have been carried out using specific combination of proteins such as Brucella abortus cell envelop protein (as antigen) and its complementary antibody (raised in mice and rabbit). A best optimized composition of biocompatible CeO2 nano-octahedra and other biocompatible materials (chitosan) was used in this study. Linear range was found in the range of 6.25 μg/m...

Introduction Scaling and integration of complementary metaloxide-semiconductor devices have made great development in the pursuit of higher performance and lower power consumption. Elemental devices of field effect transistors have been going through a transition from planar to three-dimensional structures for overcoming the physical limitation of thickness for the gate insulator. However, due ...

In this article, element free Galerkin method is used for static analysis of thin micro/nanoscale plates based on the nonlocal plate theory. The problem is solved for the plates with arbitrary boundary conditions. Since shape functions of the element free Galerkin method do not satisfy the Kronecker’s delta property, the penalty method is used to impose the essential boundary conditions. Discre...

Dye-sensitized solar cells (DSCs) promise a short energypayback time and offer a potential lowcost alternative to conventional photovoltaic devices based on semiconductors. This work describes the effort which has mainly been developed on DSSC solar cells with suitable dye for light harvesting and interfacial electron transfer processes with nano crystalline wide band-gap semiconductors. The ph...

Magnesium has been recently recognized as a biodegradation metal for bone substitute application. In the present work, porous magnesium-zinc scaffolds were prepared by powder metallurgical process and nano hydroxyapatite (HAP) coating on the Mg-3Zn (wt.%) scaffold was prepared by pulse electrodeposition and alkali treatment processes to improve the corrosion resistance of scaffold. The results ...

the level of dental and oral hygiene on elementary school age children is very low, so it can be increasing the incidence of dental and oral diseases which caused by various microorganisms. moutwash can keep dental and oral hygiene, but many commercial mouthwash is still used alcohol as their ingredients, which can be giving side effects, therefore, we still needed used alternative mouthwash, w...
