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 https://sugardaddydates.net/sugar-daddies-usa/la/new-orleans/ 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 latest Relationships ranging from Spatial Framework and you will Home Rates
Land speed comes with the complete properties out of urban room, symbolizing the new public and you will monetary features of the metropolis. Appropriately, belongings rate may be used because the indicative, that may identify the changes out of spatial construction and you may socioeconomic variations as a result of urban invention. This study tried to speak about the changes during the home rate from the a unique path structure. Methodologically, they used Space Sentence structure, that interpret metropolitan spatial design adequately, to recognize the partnership between your kinds of street networking sites and you will property price. Caused by the latest regression data exhibited the ‘integration index from Place Sentence structure is statistically tall and also a beneficial strong correlation which have residential property price. In case your integration worthy of are large, residential property rates expands proportionally. Then, using regression formula, they tried to assume the brand new homes rate transform of any out of the fresh lots nearby the fresh new ways which can be freshly opened. The research procedures or study results have the benefit of anticipating the alterations within the residential property speed within the an easy way. Simultaneously, it does donate to planners and you can enterprise professionals to establish relevant polices and you may smoothing metropolitan regeneration systems due to improving customers understanding by the providing you can efficiency and you may gurus within their property rates before performance from metropolitan regeneration and you can advancement systems.
114 Plasma Features Impact on Neon Tubing Plasma Antenna Abilities
So it report presents the research for the results off monopole antenna with neon hoses. Contained in this search, the fresh simulator and fresh means is completed. The fresh neon pipe with different duration and you can size is tailored using Computer Simulator Technology (CST) software together with characteristics off antenna factor try artificial throughout the application. CST was used so you’re able to imitate antenna variables eg come back losses, resonant regularity, obtain and you may directivity. Vector Community Analyzer (VNA) was used determine the newest get back loss of plasma antenna in order so you can examine the simulation results. Regarding simulator and you will check out, the production volume is decided which range from step 1 Ghz so you can ten Gigahertz. The outcomes show that this new come back death of plasma antenna changes whenever sized fluorescent tubes is actually varied, match various plasma features. They signifies that different philosophy from plasma services such as for example plasma regularity and you may collision regularity brings variation result of come back losses, gain and you can directivity. To your gain, the prices vary from 2.fourteen dB so you can dos.thirty-six dB. The brand new come back death of plasma antenna also offers highest worthy of range between – dB so you’re able to – dB. The greater the prices of plasma volume and you can accident volume, the better get back loss is present. The prices obtained are relative on traditional sort of metal antenna.
113 Thermal Conductivity regarding Al2O3/Water-Established Nanofluids: Revisiting the newest Affects of pH and 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.
