in order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of abadeh city.experiments were conducted in a randomized complete block design, with five treatments and five replications.in the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , ...

A novel optical fiber having its cladding doped with Au nano-particles was developed by modified chemical vapor deposition process. Absorption peaks of the optical fiber preform and the fiber appearing at 585 nm and 428 nm, respectively were due to surface plasmon resonance (SPR) of the incorporated Au nano-particles in the cladding. The measured peak wavelength of the SPR was found to increase...

The present project work deals with the machining of natural fiber composite to study the delamination effect. The natural fiber composite consists of ROYSTONEA(Royal palm fiber) and material has matrix. And this composite has been fabricated by using hand layup method after extracting the fiber by retting method. Drilling operation has been carried out on the fabricated composite by using CNC ...

Mesenchymal stem cells (MSC) have been used recently for the treatment of autoimmune diseases in murine animal models due to the immunoregulatory capacity. Current utilization of MSC requires cells in certain quantity with multiple courses of administration, leading to limitation in clinical usage. Here we efficiently treated collagen-induced arthritis rats with a single local implantation with...

the presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. to this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the research field of natural resources institute in damavand, iran. the first factor ...

The separation mechanism is a critical device that transports and releases satellites during launch on-orbit. However, as become smaller more compact, the traditional belt-locking or pyrotechnic release cannot meet micro-nano satellite’s requirements. A novel kinematic system was designed, analyzed, experimentally verified to achieve non-interference non-pyrotechnic of from vehicle while mainta...

The aim of this study is to investigate the application of polypyrrole/ polyaniline (PPy/PANI) nanofiberfor Cu (II) sorption from paper mill wastewater. The tests and their optimization results were basedon the experiments design in three levels of variables using Taguchi method. The results showed thatin Copper removal tests, the pH of the solution was the most effective para...

We demonstrate a rice leaf-like hierarchically textured polymer fiber array for anisotropic non-wetting surfaces. To provide superhydrophobicity in addition to the anisotropic behavior, fiber surfaces are spray coated with organically modified silica nanoparticles. The resulting micro/nano hierarchically structured fiber surfaces demonstrate anisotropic non-wetting properties. We designed vario...

Microfluidic technologies have recently been shown to hold significant potential as novel tools for producing micro- and nano-scale structures for a variety of applications in tissue engineering and cell biology. Over the last decade, microfluidic spinning has emerged as an advanced method for fabricating fibers with diverse shapes and sizes without the use of complicated devices or facilities....
