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 newest Interactions anywhere between Spatial Construction and Belongings Rate
Home speed comes with the comprehensive properties of metropolitan area, representing the fresh new public and financial top features of the town. Properly, belongings speed can be utilized because an indicator, that select the alterations out-of spatial structure and socioeconomic differences caused by metropolitan creativity. This study attempted to talk about the alterations when you look at the land price because of the a unique road structure. Methodologically, it observed Place Syntax, which can interpret metropolitan spatial design totally, to recognize the relationship within kinds of street communities and you will residential property speed. Caused by this new regression studies shown the latest ‘integration list out-of Area Syntax is mathematically tall and it has an excellent good correlation with residential property rate. When your combination really worth was high, house rate increases proportionally. After that, playing with regression formula, it attempted to expect the new house rates change of every from the newest lots related the newest ways which might be freshly unwrapped. The research methods or data overall performance have the benefit of anticipating the changes from inside the belongings speed during the a great way. Concurrently, it does subscribe to coordinators and you can investment executives to ascertain related polices and you will smoothing urban regeneration systems by way of improving customers information because of the bringing you can easily performance and you can masters within house rate up until the execution away from urban regeneration and you may creativity programs.
114 Plasma Qualities Effect on Fluorescent Pipe Plasma Antenna Performance
That it paper gift ideas the analysis towards abilities out-of monopole antenna with neon tubes. Inside research, brand new simulation and you can experimental method is carried out. The fresh fluorescent tubing with assorted length and you can dimensions are customized having fun with Pc Simulator Technology (CST) application as well as the functions out of antenna parameter was simulated from the application. CST was used so you can replicate antenna variables such go back losings, resonant frequency, obtain and directivity. Vector Network Analyzer (VNA) was utilized determine the new go back death of plasma antenna for the purchase to examine the simulator results. From the simulation and Recommended Site you will test, the production volume is determined which range from 1 Ghz to ten Ghz. The outcome show that brand new get back death of plasma antenna alter whenever sized fluorescent hoses are ranged, match various plasma attributes. They suggests that some other opinions out of plasma characteristics instance plasma regularity and collision volume offers variation consequence of go back losings, get and directivity. On the gain, the costs range from 2.fourteen dB to help you 2.thirty-six dB. The brand new go back loss of plasma antenna offers highest worth start from – dB to – dB. The higher the costs of plasma frequency and you may crash regularity, the better get back losings is present. The values obtained was comparative to your antique style of material antenna.
113 Thermal Conductivity out of Al2O3/Water-Mainly based Nanofluids: Revisiting the newest Influences from 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.
