You’re combination of Cu acetate and you will Al acetate very first, while the almost every other is Cu nitrate and 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 This new Connections between Spatial Build and you can Residential property Price

Property speed comes with the comprehensive characteristics of metropolitan place, symbolizing the fresh public and you may financial options that come with the metropolis. Appropriately, land rate can be used just like the indicative, which can select the changes of spatial build and you may socioeconomic variations for the reason that urban creativity. This study attempted to speak about the alterations inside the residential property speed of the a different roadway framework. Methodologically, they adopted Area Sentence structure, which can translate metropolitan spatial construction totally, to understand the relationship between the different path communities and house price. The consequence of the newest regression data shown the fresh new ‘integration index regarding Place Syntax try mathematically high and it has a good solid relationship that have land rate. Should your consolidation worthy of are higher, belongings rate develops proportionally. Next, playing with regression picture, it attempted to expect the brand new house price transform of any regarding the brand new plenty close the brand new ways which might be recently established. The study tips otherwise analysis show feel the advantage of anticipating the changes inside the residential property rate inside a simple way. At exactly the same time, it will donate to coordinators and you will opportunity executives to determine relevant polices and you can smoothing urban regeneration tactics by way of increasing people facts by the getting you can easily efficiency and you will professionals https://datingranking.net/sugar-daddies-usa/pa/philadelphia/ within their belongings rate until the execution away from urban regeneration and you will advancement strategies.

114 Plasma Characteristics Influence on Neon Tube Plasma Antenna Efficiency

That it papers merchandise the analysis towards abilities away from monopole antenna which have neon hoses. Contained in this search, the latest simulator and you may experimental approach is performed. This new fluorescent tubing with assorted length and you may dimensions are designed having fun with Computers Simulation Technical (CST) application and characteristics of antenna factor is actually simulated regarding software. CST was utilized so you can replicate antenna parameters such as for instance go back losses, resonant regularity, obtain and directivity. Vector System Analyzer (VNA) was utilized to measure the newest return loss of plasma antenna into the buy so you’re able to verify the brand new simulator abilities. Regarding simulator and experiment, the production frequency is decided which range from step 1 Gigahertz to ten Gigahertz. The outcome show that the fresh go back death of plasma antenna changes when measurements of fluorescent hoses is ranged, correspond to the many plasma features. They shows that some other opinions away from plasma services including plasma regularity and collision regularity offers improvement results of return loss, obtain and you can directivity. On the acquire, the costs range between 2.fourteen dB to help you 2.step step 36 dB. The brand new go back loss of plasma antenna offers high worth cover anything from – dB in order to – dB. The higher the prices of plasma volume and you will accident volume, the greater go back loss can be found. The values obtained is actually comparative to the old-fashioned sort of metal antenna.

113 Thermal Conductivity regarding Al2O3/Water-Established Nanofluids: Revisiting this new Influences away from 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.
