One is combination of Cu acetate and Al acetate earliest, and other are Cu nitrate and you will Al nitrate

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 Affairs between Spatial Build and you may Homes Rate

Homes price has got the full qualities out of metropolitan space, symbolizing brand new personal and you may financial features of the town. Consequently, land rates may be used while the an indicator, that can pick the alterations out-of spatial design and socioeconomic differences as a result of metropolitan innovation. This study made an effort to mention the alterations inside belongings rates by the another roadway construction. Methodologically, it used Area Sentence structure, that may interpret urban spatial design totally, to spot the relationship involving the forms of street networking sites and you may homes rates. The result of the regression investigation demonstrated the ‘combination list away from Area Sentence structure was statistically significant and it has a good correlation that have home speed. Should your combination well worth are high, house price develops proportionally. Then, playing with regression formula, they made an effort to assume the new residential property rate transform of any of the fresh new plenty close the new ways that are newly opened. The analysis procedures or studies performance have the advantageous asset of predicting the changes during the home rates within the an easy way. Concurrently, it does donate to planners and you will endeavor executives to determine associated polices and you may smoothing urban regeneration tactics as a result of increasing residents facts by the taking you are able to results and you will gurus within homes price up until the execution regarding metropolitan regeneration and you may innovation projects.

114 Plasma Functions Effect on Neon Tubing Plasma Antenna Efficiency

So it papers gift suggestions the study towards show regarding monopole antenna which have fluorescent tubes. Within lookup, the fresh simulator and you may experimental strategy is completed. The fresh fluorescent tube with assorted duration and you will size is customized using Computer system Simulator Technical (CST) software additionally the attributes of antenna factor are simulated regarding app. CST was applied so you’re able to imitate antenna variables including come back losings, resonant regularity, obtain and you may directivity. Vector System Analyzer (VNA) was applied determine the fresh return death of plasma antenna from inside the acquisition to help you validate new simulator overall performance. On the simulation and you may try, the production volume is set starting from 1 Gigahertz in order to 10 Ghz. The outcome show that the brand new come back loss of plasma antenna change whenever measurements of neon tubes is actually ranged, match the various plasma qualities. It signifies that more values off plasma attributes including plasma volume and you may collision volume gets distinction results of come back loss, acquire and directivity. Towards get, the values range between 2.fourteen dB to help you 2.thirty six dB. The newest come back death of plasma antenna also provides high really worth range from – dB to help you – dB. The higher the prices away from plasma volume and accident regularity, the greater get back losses is obtainable. The prices obtained is actually comparative to your traditional type of material antenna.

113 Thermal Conductivity out of Al2O3/Water-Based Nanofluids: Revisiting the Impacts off 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.
