- Maintain appearance of the initial particles so It has not been densified by sintering means
- Sintered specimen of 1650℃ is more density than 1400℃ beacause of crevice and the pores that were distributed in less (not much difference)
- Particle si
of the soil particle size3) The microstructure of the soil water content4) Soil washing suitability of the site
■ Design process of Phytoremediation
Area X Depth = Volume of soil
Volume X Density = Mass of soil
3. Soil’s mass X Heavy metal’s concentration
= Total amount of heavy metal calculate
4. ③ - concern standard = Disposal amount
5. Plant’s biomass and distribution rat
Particles between 0.1 ~ 10 ㎛
Colloid is state that a substance microscopically is distributed in another substance
Dispersed phase/ dispersion medium
A mixture of two or more liquids that are normally immiscible and, one liquid (the dispersed phase) is dispersed in the other (the continuous phase).

*’Nano’ means….
Nanometer: one billionth of a meter
Nano-: prefix comes from the Greek word for ‘dwarf’
Chemical, physical, and biological properties that differ from those of their larger, or bulk counterparts
Nanotechnology: The National Nanotechnology Initiative(NNI)-> the science of materials and phenomena in the range of 1 to 100nm in diameter

The atmosphere shields us from the sun's cancer-causing ultraviolet (UV) radiation and also moderates the earth's climate.
The atmosphere is obviously vital for human existence, but we have nevertheless been polluting it for years.
