Dimethyl ether (DME) burns with no particulate matters (PM), no sulphur oxides (SOx), and less nitrogen oxides (NOx). Therefore, DME is expected as a clean fuel for the 21st century. DME is able to replace LPG and light oil. It is also expected as a hydrogen carrier and storage. From these things, developments of economical production methods and the excellent synthesis catalysts are needed.
If a classical sensor is contacted with a surface acoustic wave device, passive and wireless sensor is realized. As the classical sensor depends on temperature, temperature calibration is needed. We propose novel temperature compensation method.
Our technology is expected as one of clean energy. A novel material which has both changing and discharging abilities is formed by biomineralization. This process enables to develop a novel device for supplying electric power on treatment of organic waste.
