The Barrett-Joyner-Halenda (BJH) method for calculating pore size distributions is based on a model of the adsorbent as a collection of cylindrical pores. Thetheory accounts for capillary condensation in the pores using the classical Kelvin equation, which in turn assumes a hemispherical liquid-vapor meniscus and a well-defined surface tension.

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.

the communication with L1 speakers. Therefore, if L2 speakers want to learn their target language, the experience of a “real communicative situation” with L1 speakers is important.
In previous studies and research by scholars and experts on SLA and feedback, it is revealed that there are many methods of feedback and advantages for each respective method. For our study, our group decided to
