-Thermophysical property data (density, surface tension, viscosity) of high temperature melts have released-
Release date: 2010/04/13
Summary of recorded data
Thermophysical property data of high temperature melts of pure metals have been recorded and released in cooperation with Takehiko Ishikawa, an associate professor at Japan Aerospace Exploration Agency (JAXA). Density, surface tension and viscosity of 22 materials listed below were recorded. These properties have been measured by the electrostatic levitation method. And valuable data of melts such as tungsten has a high melting point exceeding 3,000 degrees celsius have also been recorded.
List of recorded materials
Tungsten, Titanium, Zirconium, Niobium, Vanadium, Cobalt, Nickel, Yttrium, Molybdenum, Ruthenium, Rhodium, Palladium, Hafnium, Tantalum, Rhenium, Osmium, Iridium, Platinum, Lanthanum, Praseodymium, Neodymium, Cerium
Electrostatic levitation (ESL) is the method can measure various properties of molten metal without touching. Containerless float methods, including ESL, can avoid sample contamination because it has no reaction between container and sample. It can also produce supercooled state for solidifying for long periods of time. Therefore it is probably suitable for study on supercooled liquid. To measure density by ESL, calculate volume from camera image and mass divided by volume because its sample shape in suspension is nearly a sphere. Surface tension and viscosity are obtained from attenuance of frequency or vibration from vibrating a few drops of high temperature melt. (See reference 1 for details.)

Title: Development of thin film thermophysical property database(1)
Author: Yuichiro Yamashita, Tetsuya Baba, Naoyuki Taketoshi, Takashi Yagi, Nobuto Oka(Aoyama Gakuin University), Yuzo Shigesato(Aoyama Gakuin University)
We gave a talk titled above at "Micro/Nano Scale Thermophysical Properties and System Design -V" on the second day of the 30th Japan Symposium on Thermophysical Properties. We examined the material structure configuration of thin film, and devised the data structure of the database based on it. And we also reported the development status of our database.

Title: Development of Network Database System for Thermophysical Property Data having integrated system
Author: Yuichiro Yamashita, Tetsuya Baba
The paper on our database appeared in "Journal of Japan Society of Information and Knowledge Vol.19 No.2". The contents of this paper was presented at JSIK 17th Annual Meeting held in May 2009. Now, Thermophysical Property Database Developed by JSTP and our database are running on the same program, and the concept of distributed become a growing reality. We reported the expansion of the InetDBGV browsing software and some instructions for use of new functions to seamlessly integrate and browse these databases. This paper is available for download from J-STAGE for free.

-InetDBGV ver3.0.6 release-
New function of ver3.0.6
1.Reference search function
It is bossible to search property data by paper title, journal title, issue / year / page and author.
2. Multiple Concurrent Connection & Cross Search Function
It became possible to connect to multiple network thermophysical property database concurrently, for example, JSTP sever and AIST server. Therefore, the function that it is possible to search across multiple database was added.
3. Record of image data
It became possible to record and release the data that is difficult to express in numeric data such as SEM/TEM image or spectral image.
Browsing system by web browser
It is possible to use simple search or data comparison of the browse system without depending on a certain OS or browser.
TPDS-web lightweight version can be used via IE, GC, and have a light load.
Exclusive soft for browsing DB
InetDBGV is the database browsing software can be used by installing onto your Windows OS. Compared to the web browser version, it has several functions corresponding to higher and technical needs like property search or 3D graph plot using a large quantity of data.
