You’re blend of Cu acetate and you may Al acetate basic, and most other are Cu nitrate and you may 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 The new Affairs anywhere between Spatial Design and you can Homes Rates

Home price contains the comprehensive services away from urban place, symbolizing the latest personal and you will economic top features of the metropolis. Appropriately, land rate can be used because the an indicator, which can select the changes away from spatial construction and you will socioeconomic distinctions as a result of urban development. This study attempted to discuss the changes from inside the land price of the another street build. Methodologically, it then followed Room Sentence structure, that can interpret urban spatial construction comprehensively, to understand the partnership involving the forms of highway sites and you will house rate. The consequence of the latest regression study presented the new ‘integration directory away from Place Syntax are statistically high and has good strong relationship which have property rate. If the integration really worth is large, land rates expands proportionally. After that, having fun with regression formula, it tried to assume the fresh property rates change each and every off the fresh lots encompassing the fresh roads which might be freshly established. The analysis methods otherwise data efficiency feel the advantageous asset of forecasting the changes during the property rates in the an easy way. Additionally, it does sign up for planners and venture managers to determine associated polices and you will smoothing urban regeneration strategies through improving residents knowledge because of the delivering you can abilities and masters within their house rates up until the delivery out-of metropolitan regeneration and you can innovation strategies.

114 Plasma Characteristics Impact on Neon Tube Plasma Antenna Show

Which paper gift ideas the study to your overall performance of monopole antenna with neon tubes. Within lookup, the new simulator and you may experimental method is conducted. The neon pipe with different length and you can dimensions are customized playing with Computer system Simulation Tech (CST) application while the features from antenna factor is actually artificial on application. CST was utilized so you can replicate antenna variables such come back loss , resonant volume, acquire and you will directivity. Vector System Analyzer (VNA) was used determine the new go back death of plasma antenna from inside the purchase to help you verify this new simulator performance. On simulation and you can check out, the supply volume is decided which range from 1 Gigahertz in order to ten Gigahertz. The outcome show that the come back death of plasma antenna changes when measurements of fluorescent tubes try varied, match the different plasma qualities. It implies that some other opinions away from plasma properties for example plasma frequency and collision regularity brings differences result of come back losings, obtain and you may directivity. Into obtain, the costs range between 2.14 dB so you’re able to 2.thirty six dB. The newest get back loss of plasma antenna offers large well worth may include – dB to – dB. The greater the prices out-of plasma volume and you may accident frequency, the higher get back loss exists. The prices received are comparative into the conventional type of material antenna.

113 Thermal Conductivity from Al2O3/Water-Situated Nanofluids: Revisiting the brand new Impacts out-of pH and you may 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.
