  • The salt accumulation on the soil surface can be mathematically described. Although the movement of salts in soil solution is expressed in terms of mathematical model, which has certain limitations in practical application, except the exchangeable and absorbable state salts in soil solution. This model is illustrated by analyticl experiments in which evaporation from the bare soils, transpiration of plants and rainfall are required. Agreement between the model and the measured data was satisfactory, which validating the salt accumulation theory on the soil surface.

  • We introduce the inline type mass production tool for the large size lighting OLEDs and flexible OLEDs. The manufacturing tool includes the linear belt source what is new concept for the organic deposition processes and the deposition operation combines directly to the encapsulation operation in a tool. The linear belt source evaporation in deposition processes is performed during the substrate transferring to innovatively improve the productivity in manufacturing.

  • Optical absorption properties of an orphous Se film due to interband electronic transitions are observed in the visible range by varying the folm thickness. Amorphous Se films were prepared by evaporation method. As the experimental results, it is found that optical energy gap is around 2.07(e V), and the optical constants depend on the film thickness, evaporation-deposition conditions, and incident photon energy.
