High Temperature Superconductivity:Past, Present and Future
ثبت نشده
چکیده
The superconductivity was discovered in 1911. In the same year, Sumitomo Electric Wire & Cable Works was established (Foundation was in 1897 as Sumitomo Copper Rolling Works), and laid the first Japan-made high-voltage underground cables. In 2011, we will celebrate the centennial anniversary of the discovery of superconductivity, and a high-temperature superconducting (HTS) power cable will be energized at the Asahi Substation of Tokyo Electric Power Company connecting with their power grid for the first time in Japan. The above mentioned HTS cable demonstration project (so called as Yokohama Project) has been supported by Ministry of Economy, Trade and Industry (METI) and New Energy and Industrial Technology Development Organization (NEDO) since 2007. In 1986, high-temperature superconductivity was discovered. The past, present and future perspective based on 24 years’ activity of high temperature superconductivity will be summarized.

An Improvement in Thermal and Rheological Properties of Water-based Drilling Fluids Using Multiwall Carbon Nanotube (MWCNT)
Designing drilling fluids for drilling in deep gas reservoirs and geothermal wells is a major challenge. Cooling drilling fluids and preparing stable mud with high thermal conductivity are of great concern. Drilling nanofluids, i.e. a low fraction of carbon nanotube (CNT) well dispersed in mud, may enhance the mixture thermal conductivity compared to the base fluids. Thus, they are potentially ...

Background and objectives: Climate change has been a serious issue in the last two decades and many studies have focused on its various aspects. Therefore, it is necessary to determine the future habitat of rangeland species present and future years, under climate warning models. In this regard, it should be investigated whether the increase in temperature will have a positive effect on the pre...

Climate change due to increasing the concentration of greenhouse gases (especially CO2) in the atmosphere causes changes in the rainfall regime, runoff rate, wind speed and solar radiation of atmosphere. In the present research, the maximum and minimum temperature parameters were simulated during the base period of 1979-2088 and two future periods of 1979-2070 and 2070-2090 using daily ...
