3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
Basic principles

basic factor of quality change following the activity of microorganism and enzyme
Motive of the research
Europe, US, Japan, China – Activation of application about ‘non-heating process’ through development of the efficient pressure system
Examination about using possibility of high pressure which can promote the quality improvement by microorganism, enzyme activation, fresh flavo
An organic light emitting diode (OLED) is a solid state device like the LED but composed of several layers in which the emissive electroluminescent layer is a film of organic compounds which emit light in response to an electric current.
Function of each part
Cathode : injecting electron composed of metal
Anode : injecting hole composed of transparent ITO
Emissive polymer : reco
Significantly higher surface area and much narrower pore size distribution in the mesopore region
A large amount of amine-type CO2 capturing agent into its mesopores in a well dispersed manner
Synthesis of MA
PEI impregnation on MA
Amine grafting on MCM-41
Characterization of the materials prepared
CO2 adsorption-desorption measurement
Al(i-PrO)3 (41.68g)+ Alcohol solvent
Lenses are launched into the space
Lenses find their assigned position
Lenses play a role as blocker
Lens material properties required
-Regarding cost
-In order to keep costs down, the lenses will need to be as light as possible
-weigh around 0.04 ounces (1 gram)
-Regarding survivor
- 24/7 heat of the sunlight without changing its properties

eco-friendly. To match our concept, we’re going to outsource CJ which is really famous for eco-friendly food. ‘Bibigo’ is a kind of Korean food chain store. Their main menu is ‘bibimbab’ which is representative traditional Korean food. Bibimbab’s main material is fresh vegetable. It is good for health and not heavy on the stomach. And it also can satisfy various customers’ needs.
such as visible or ultraviolet light
Absorption and generation of exciton
Dissociation and separation
Transport and collection
PCBM has a drawback and thus contributed very little to the absorption of solar light.
- using other acceptors which absorbs at longer wavelengths
- stacking solar cells based on materials that absorb in different wavelength region
3. Experiment Method
A measurement method of sample of powder form is an x-ray diffractometor(Fig. 9).

3.1. Making of Sample Powder
A Sample is made a powder form. A diameter of powder has good reproducibility as smaller. But generally 10~35μm is a suitable size of sample. We must caution a deterioration by air, gas, humidity and pouri
1. Why we choose E-Land
E-Land has been popular for its unique management style. Growing steadily, this group has used KMS(knowledge management system), and it is considered as very important elements of the company’s growth.
They are asking through ‘learning position’, taking advices through ‘listening position’ and sharing ‘ambitious attitude’, ‘attitude of looking themselves
