self-assembly of densely packed zno nanorods were grown on porous silicon (ps) substrate by low-temperature chemical bath deposition. the structural and optical properties of the obtained zno nanostructures on ps substrate were systematically studied. the strong and sharp (002) peak compared with other peaks in the x-ray diffraction (xrd) indicated thatzno nanorods formed with superior orientat...
Due to the lack of scientific knowledge for the use of substrate and best fertilizing method in the growth of Araucaria excelsa, it is crucially important to find the most appropriate planting substrate and fertilizing method. The effect of conventional fertilizing method and the application of Fe nanofertilizer were studied on the growth of A. excelsa in which six fertilizing methods and three...
this research was carried out to evaluate the effect of super-absorbent and manure on growth, yield, physiological and biochemical characteristics of geranium under deficit irrigation at research greenhouse of faculty of agriculture, lorestan university, iran, in 2014. the experiment was arranged factorially based on a completely randomized design with six replications. factor a was substrate c...
This research was performed to study the effect of direct planting and transplanting of potato minituber on its yield and yield components. The experiment was designed as a randomized complete blocks with nine treatments and three replications. Treatments were one direct and eight indirect planting. In order to prepare the nursery, two types of pots (peat and nylon) and four types of substrates...
The use of suitable substrate for vegetable production may reduce losses in production caused by salinity. In order to determine suitable substrate for bell pepper cv. 'California Wonder' under salinity stress conditions, a factorial experiment based on completely randomized design with 4 replications was performed. The experiment consisted of three factors of substrate (coconut fibre, 50% fine...
In the present study, packaging of a greenhouse-grown tomato on the culture medium containing 0, 25, 50, 75 and 100% compost tea under modified atmosphere: MA (88%N2 + 8%CO2 + 4%O2) in polyethylene and nanosilicon-polyethylene bags was studied at 5°C for 30 days. Several quality parameters such as moisture content, pH, total soluble solids (TSS), titratable acidity (TA), Vitamin C content, text...
The purpose of this research is to laser cladding of stellite6 and stainless steel 17-4PH powders on the substrate of stainless steel 17-4PH, and investigate its solidification microstructure. The results showed that the microstructure of the stellite6 cladding has a cobalt solid solution ground phase with an FCC structure and Cr7C3 and Cr23C6 carbides. Also, the values of the primary dendrit...
silicon nanowire (sinw) arrays were produced by electroless method on polycrystalline si substrate, in hf/ agno3 solution. although the monocrystalline silicon wafer is commonly utilized as a perfect substrate, polycrystalline silicon as a low cost substrate was used in this work for photovoltaic applications. in order to study the influence of etching time (which affects the sinws length) on d...
در این تحقیق، رفتار خستگی آلیاژ 7075 آلومینیوم تولید شده به روش "spray casting" تحت بار ثابت و متغیر، بررسی شده است . این روش یکی از روش های تولید شمش یا قطعه نهایی است که سبب بهبود خواص مکانیکی خصوصا خستگی و خزش می شود. در این روش یک جریان (stream) از فلز مذاب توسط گازی خنثی با سرعت بالا، مانند آرگون و یا نیتروژن، اتمیزه می شود و این توده به سوی جمع کننده (substrate) هدایت می شود. با برخورد ذر...
