The growth rate and uniformity of Carbon Nano Tubes (CNTs) based on Chemical Vapor Deposition (CVD) technique is investigated by using a numerical model. In this reactor, inlet gas mixture, including xylene as carbon source and mixture of argon and hydrogen as carrier gas enters into a horizontal CVD reactor at atmospheric pressure. Based on the gas phase and surface reactions, released carbon...
conclusions not using iron supplementation did not cause of anemia in women with hb concentrations greater than 13.2 g/dl during pregnancy; thus, the systematic care and control of iron status markers without iron supplementation is recommended for these women. results there were statistically significant differences between the two groups in hb (p = 0/03) and ferritin (p = 0/04) levels at the ...
iron reducing bacteria (irb) are one of the most applicable microorganisms in various industrial and environmental activities. these bacteria play a main role in the natural iron transformation. they act in a reverse metabolic pathway in contrast to iron oxidizing bacteria. in the anaerobic conditions irb are capable to use ferric ion as the final electron acceptor and reduce fe3+ to fe2+. what...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
Abstract Introduction: Researches have been shown if water and wastewater treatment systems properly managed, it provides a major part of water reservoirs for the needs of developing countries. Because of the uncontrolled increase in concentrations of fine particle materials, organic and inorganic compounds and especially heavy metals in water, the conventional methods of treatment is not able...
UNLABELLED Iron deficiency is the most common nutritional disorder worldwide with substantial impact on health and economy. Current treatments predominantly rely on soluble iron which adversely affects the gastrointestinal tract. We have developed organic acid-modified Fe(III) oxo-hydroxide nanomaterials, here termed nano Fe(III), as alternative safe iron delivery agents. Nano Fe(III) absorptio...
Iron oxide as a burning rate catalyst commonly used in many of solid composite propellants. As the particle size of this component decreased, the final properties of the propellant change. In this research, effects of using 1 percent by weight of nano hematite iron oxide (α-Fe2O3) investigated on properties of an HTPB/AP/Al formulation and compared with the same propellant containing micronized...
Soil and water salinity in semi-arid regions such as Iran have been a important threat for plant growth and agriculture. It is demonstrated that TiO2 nanoparticles can improve plant growth and increase stress tolerance in plants. Therefore, in current study, a pot experiment was conducted as factorial with completely randomized design to evaluate the effect of 3 levels of salinity (0, 50, ...
Metallic nanoparticles have huge applications in all the fields including agriculture and its allied sciences. This study aims at evaluating possible implications of iron oxide nanoparticles on the growth and development of rice (Oryza sativa L.). Rice is feeding hunger of half of the World’s population and yet found to be highly sensitive towards iron deficiency especially at seedling stage. T...
nano-encapsulated iron oxide in zirconium oxide-coated mica pigments are thermally stable,innocuous to human health, non-combustible, and they do not conduct electricity. they could beapplied in several industries such as thermoplastics, cosmetics, food packaging, children toys, paints,automobiles coating, security purposes, and banknotes. nowadays, they are highly desirable inceramic decoratio...
