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 new Relationships ranging from Spatial Construction and you will Residential property Rate
Homes price contains the comprehensive qualities regarding metropolitan area, symbolizing this new social and you may economic popular features of the town. Appropriately, residential property price can be used given that an indication, that pick the alterations regarding spatial design and socioeconomic distinctions for the reason that metropolitan creativity. This research made an effort to talk about the alterations from inside the house rate by a separate path design. Methodologically, it used Area Syntax, that translate metropolitan spatial design totally, to understand the relationship between the different highway networks and property rate. The consequence of this new regression study shown new ‘consolidation directory of Space Syntax was mathematically extreme and contains a good relationship that have home speed. In case the integration value is actually highest, property price increases proportionally. Then, playing with regression picture, they made an effort to predict brand new homes rates changes of any out of the lots close new ways that will be freshly established. The research procedures otherwise research overall performance feel the benefit of predicting the changes within the belongings price in an easy way. As well, it will subscribe to planners and venture professionals to ascertain related polices and smoothing urban regeneration projects thanks to boosting customers wisdom by bringing you are able to show and you can experts inside their homes rates till the execution off urban regeneration and you can advancement plans.
114 Plasma Characteristics Influence on Fluorescent Tubing Plasma Antenna Abilities
It paper merchandise the research on performance regarding monopole antenna having fluorescent hoses. Within this look, this new simulator and you can experimental strategy is performed. This new neon tubing with different length and dimensions are tailored playing with Pc Simulator Technology (CST) application together with characteristics out-of antenna parameter is simulated regarding app. CST was utilized in order to replicate antenna parameters such as for instance return losses, resonant volume, acquire and you may directivity. Vector Community Analyzer (VNA) was applied determine this new go back death of plasma antenna for the order so you’re able to validate the latest simulator results. Regarding simulator and you may test, the production volume is sugar baby Albany NY determined ranging from 1 Ghz so you’re able to ten Ghz. The outcomes reveal that the fresh get back loss of plasma antenna transform when measurements of neon tubes are ranged, correspond to different plasma qualities. It means that more opinions away from plasma features such plasma volume and you can collision frequency gives improvement consequence of come back losings, acquire and you may directivity. To the gain, the values start from dos.fourteen dB so you can 2.step 36 dB. The new go back death of plasma antenna also offers highest worth cover anything from — dB so you’re able to — dB. The greater the prices out of plasma regularity and you can accident volume, the better return losings can be acquired. The costs gotten was comparative toward traditional type of material antenna.
113 Thermal Conductivity out-of Al2O3/Water-Depending Nanofluids: Revisiting the fresh new Affects off pH and you will 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.
