One is mix of Cu acetate and you may Al acetate first, while the other are Cu nitrate and you can Al nitrate

CuAlO_dos thin films are prepared on Si or sapphire substrate by sol-gel method using two kinds of sols. In the case of acetate sol, XRD peaks of CuAlO₂ observed at annealing temperature of 800-950 ?C on both Si and sapphire substrates. In contrast, in the case of the films prepared using nitrate on Si substrate, XRD peaks of CuAlO₂ have been observed only at the annealing temperature of 800-850 ?C. At annealing temperature of 850?C, peaks of other species have been observed beside the CuAlO₂ peaks, then, the CuAlO₂ peaks disappeared at annealing temperature of 900 °C with increasing in intensity of the other peaks. Intensity of the other peaks decreased at annealing temperature of 950 ?C with appearance of broad SiO₂ peak. In the present, we ascribe these peaks as metal silicide.

115 Brand new Relationships ranging from Spatial Framework and you will Property Rate

Land price gets the total characteristics out of metropolitan room, representing the fresh personal and you may economic attributes of the town. Consequently, property price may be used due to the fact an indication, that can pick the alterations from spatial design and you can socioeconomic distinctions for the reason that metropolitan development. This study made an effort to discuss the alterations into the belongings rate by the an alternative path framework. Methodologically, they adopted Place Sentence structure, which can understand urban spatial build totally, to determine the partnership involving the different roadway systems and you will property speed. The result of new regression research demonstrated the ‘combination directory out of Place Syntax is statistically significant and has a great solid correlation which have property rate. Whether your consolidation really worth is highest, homes rate develops proportionally. After that, using regression formula, they tried to expect the newest homes rates change of each and every out of the fresh lots surrounding the latest roads that will be recently unwrapped. The study methods otherwise data overall performance have the advantageous asset of anticipating the changes in the land rate in a simple way. On the other hand, it can sign up for planners and you can venture managers to determine relevant polices and you can smoothing metropolitan regeneration plans compliment of increasing customers knowledge because of the bringing you’ll be able to performance and gurus inside their homes rates

until the performance from urban regeneration and you can invention programs.

114 Plasma Services Affect Fluorescent Tube Plasma Antenna Efficiency

So it papers presents the study into show off monopole antenna having fluorescent hoses. Within search, the brand new simulation and fresh strategy is completed. New neon pipe with various size and you will dimensions are tailored having fun with Computers Simulation Technology (CST) software and also the qualities out-of antenna factor is actually simulated on the app. CST was applied in order to replicate antenna parameters eg get back losses, resonant regularity, get and you may directivity. Vector System Analyzer (VNA) was applied to measure the fresh come back loss of plasma antenna inside order so you’re able to validate the latest simulator show. On the simulation and you can experiment, the supply frequency is determined which range from 1 Gigahertz to 10 Gigahertz. The outcome show that brand new come back death of plasma antenna changes when size of fluorescent tubes are varied, correspond to the various plasma characteristics. They shows that some other opinions away from plasma qualities instance plasma regularity and accident frequency gives differences result of come back losses, obtain and you will directivity. With the gain, the prices may include dos.14 dB so you’re able to dos.thirty six dB. New come back loss of plasma antenna now offers highest worthy of are priced between — dB so you’re able to — dB. The greater the prices of plasma regularity and you can crash regularity, the better get back losses is obtainable. The values obtained are relative with the antique particular material antenna.

113 Thermal Conductivity from Al2O3/Water-Oriented Nanofluids: Revisiting brand new Affects out-of pH and Surfactant

The present work focuses on the preparation and the stabilization of Al₂O₃-water based nanofluids. Though they have been widely considered in the past, to the best of our knowledge, there is no clear consensus about a proper way to prepare and stabilize them by the appropriate surfactant. In this paper, a careful experimental investigation is performed to quantify the combined influence of pH and the surfactant on the stability of Al₂O₃-water based nanofluids. Two volume concentrations of nanoparticles and three nanoparticle sizes have been considered. The good preparation and stability of these nanofluids are evaluated through thermal conductivity measurements. The results show that the optimum value for the thermal conductivity is obtained mainly by controlling the pH of the mixture and surfactants are not necessary to stabilize the solution.
