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 New Relationships anywhere between Spatial Construction and you will Land Rates
Residential property speed contains the total qualities off metropolitan room, symbolizing the fresh new societal and you can economic options that come with the city. Appropriately, house rate can be utilized because an indicator, that identify the changes away from spatial build and you will socioeconomic variations for the reason that urban innovation. This study attempted to talk about the changes into the land rate of the an alternative roadway build. Methodologically, they accompanied Area Syntax, that can interpret metropolitan spatial design adequately, to identify the connection involving the different roadway networking sites and you will property speed. Caused by the newest regression research shown the fresh ‘combination list from Room Sentence structure are statistically high and contains a good correlation that have property price. If for example the consolidation worthy of is actually highest, belongings speed grows proportionally. Subsequently, playing with regression picture, it made an effort to anticipate brand new homes price alter of each away from the fresh plenty surrounding the newest courses that will be freshly open. The analysis actions otherwise data efficiency have the advantage of predicting the changes into the snap the site home rate in the an easy way. At exactly the same time, it does join planners and you may investment professionals to ascertain relevant polices and smoothing metropolitan regeneration systems as a result of boosting residents skills from the providing you’ll be able to results and you can pros inside their residential property rates before execution off urban regeneration and innovation projects.
114 Plasma Services Impact on Neon Tube Plasma Antenna Results
Which report gift ideas the analysis for the overall performance regarding monopole antenna which have neon hoses. Contained in this lookup, the latest simulator and you will fresh method is performed. The neon pipe with different length and you can dimensions are designed using Desktop Simulator Technical (CST) app plus the properties out of antenna factor try artificial throughout the app. CST was applied in order to imitate antenna details such as return losings, resonant volume, gain and directivity. Vector Community Analyzer (VNA) was applied to measure brand new come back loss of plasma antenna in purchase to help you verify this new simulator show. On the simulator and you will try, the supply regularity is decided including 1 Gigahertz so you’re able to ten Gigahertz. The results show that the newest return death of plasma antenna changes when size of neon hoses is ranged, correspond to the various plasma functions. It means that various other thinking away from plasma qualities particularly plasma regularity and you may accident frequency provides differences result of come back losses, obtain and directivity. Into gain, the costs are normally taken for dos.fourteen dB so you’re able to dos.thirty-six dB. The fresh come back death of plasma antenna offers highest value vary from – dB to – dB. The greater the prices of plasma volume and you can accident volume, the greater come back losses can be acquired. The values received is comparative on traditional version of steel antenna.
113 Thermal Conductivity out-of Al2O3/Water-Established Nanofluids: Revisiting the new Has an effect on 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.
