3. Requirements of EUV resist
EUV is highly absorbed by all materials, even EUV optical components inside the lithography tool are susceptible to damage, mainly manifest as observable ablation. Such damage that is associated with the high-energy process of generating EUV radiation is a new concern specific to EUV lithography .
EUVL's shorter wavelength also increases flare, resulting in less
3) The superiority of Ti plate as the substrate of dye-sensitized solar cells
This figure is light irradiation in DSSC's based on (a) metal substrate(Ti, stainless steel) and (b) FTO substrate. In this paper, nano crystalline TiO2 coated on FTO, Ti and stainless steel substrated was applied as a photoelectrode of DSSCs.
In conclusion, the sheet resistance of metal substrate seems to be const

There exists under ground Pit as a previous
car-press factory before present establishment.
Moisture resulted from inner underground pit goes up to the factory and results serious faulty of semiconductor component !

Process Selection Considerations
Selection of an activated-sludge process for BOD removal and nitrification is a function of many considerations including specific site constraints, compatibility with the existing process, compatibility with existing equipment, present and future treatment needs, level of capability of the operating staff, capital costs, and operating cost.

Flowrate
Present Average Flowrate = 4220 m3/d
Water use per capita = 4220/15000 = 0.281333 m3/d capita
Population after 10 years = 15000 Χ 1.0310 = 20158.75 ≒ 21000 capita
∴ Average Flowrate = 0.281333 Χ 21000 = 5908 m3/d ≅6000m3/d
Peak Flowrate = 5908 Χ 1.5 = 8862 m3/d ≅9000 m3/d

particles, possibly due to strong absorption by carbon.). For example, a 10nm size particle was selected Fig.3a and a spot analysis was conducted. From the acquired spectrum Fig.3b, the particle was identified as another Nb precipitate. Prior to this study, it was certain that Nb precipitates as particles above 50nm in steel, but identifying precipitates below this size was not clarified. However
3. Introduction
What is the Bio-fuel ?
- Bio-fuel is derived from biological materials which are commonly plant materials used. The purpose is to make a “sustainable transportation fuel” from biomass.
What is Bio-ethanol ?
- Bio-ethanol has been produced from biological source.
- It is produced in fermentation of sugars in the brewing industry. In this process glucose is
