CuAlOdos 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 The fresh Relationships between Spatial Framework and you will Belongings Speed
Property speed contains the total services of metropolitan area, representing the fresh new public and you will economic popular features of the city. Correctly, homes rate can be used due to the fact an indicator, that may select the alterations regarding spatial construction and you can socioeconomic variations caused by metropolitan invention. This research attempted to talk about the changes inside the home rates from the yet another road build. Methodologically, they observed Area Syntax, that can translate urban spatial framework totally, to recognize the relationship involving St Louis MO sugar daddy the kinds of highway channels and you may house rate. Caused by brand new regression data showed the brand new ‘combination list away from Area Syntax is actually statistically tall and contains a good correlation with homes rate. In case your integration really worth is highest, residential property price grows proportionally. After that, playing with regression formula, they made an effort to expect this new belongings rate changes of each of brand new plenty surrounding the fresh paths which can be recently established. The study methods or investigation performance feel the advantageous asset of anticipating the changes into the property rate in the a simple way. On top of that, it does sign up to coordinators and you can endeavor managers to establish associated polices and you will smoothing urban regeneration plans due to improving citizens knowledge of the getting you’ll be able to show and masters within belongings price before the performance regarding metropolitan regeneration and you will creativity projects.
114 Plasma Characteristics Effect on Fluorescent Tube Plasma Antenna Show
So it report presents the study towards the performance regarding monopole antenna that have fluorescent hoses. Within this lookup, the fresh new simulation and fresh approach is completed. The fluorescent tube with various duration and you may dimensions are designed having fun with Computers Simulation Technology (CST) software and services from antenna parameter was simulated throughout the software. CST was applied so you can replicate antenna variables like go back losings, resonant regularity, get and directivity. Vector System Analyzer (VNA) was used determine the newest get back loss of plasma antenna inside order to help you verify the latest simulation efficiency. Regarding simulator and you will check out, the supply frequency is decided ranging from 1 Ghz in order to ten Ghz. The results reveal that the new go back death of plasma antenna change whenever measurements of fluorescent hoses was ranged, match different plasma features. They means that various other thinking out-of plasma properties like plasma frequency and you can accident regularity gives improvement outcome of go back loss, obtain and you can directivity. Toward get, the values may include dos.fourteen dB to help you 2.thirty-six dB. The brand new get back death of plasma antenna now offers higher well worth include – dB so you can – dB. The greater the values from plasma frequency and you can collision regularity, the higher get back losses is present. The prices received was comparative toward old-fashioned sorts of metal antenna.
113 Thermal Conductivity from Al2O3/Water-Dependent Nanofluids: Revisiting the newest Influences out-of pH and you can 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.
