of Russia also makes a various climate zone. Basically, Russia has continental climate which is a climate characterized by very long cold winter and short cool summer. An annual range varies in different localities in a large scale. An average temperature of winter is -10℃ and that of summer is 16℃. The severe cold of Russia winter has a wide influence on Russian’s various activities like f
2. Important Characteristics of TiO2
(1) Photocatalystic Character
- If the light energy is irrigated at TiO2, the catalyst which absorbed the light energy will activate so it oxidize and restore aspirates.
(2) Characteristic of Ultra-hydrophile
- Ultra-hydrophile is the status that befit with the surface of the material such as glass.

In this stream, the energy of nuclear fission and nuclear fusion, solar energy, subterranean heat energy, hydrogen energy, tidal energy and so on are researched with activity by scientists. Among them, hydrogen energy system supremely comes into the spotlight. Hydrogen energy system bases an ideal pr

of wafer. Second step is to remove any oxide layer that may have built up. The last step removes any ionic or heavy metal contaminants.
The RCA clean procedure should be performed immediately prior to any crucial step, especially those involving high temperatures. For safety reasons, all activities in the RCA clean procedure should be performed in a Clean Station Work Area which is located under
