nano-world)의 정복을 가능케 하였으며, 나노입자(nano-particle), 나노코팅(nano-coating), 나노섬유(nano-fiber)의 활용을 통한 혜택은 현재 많은 이들에 의해 입증되고 있는 중이다.
나노 기술을 이용한 의류 가공에 있어서, 후 가공 공정 중 나노구조를 발현시키는 방법이 있다. 나노물질이나 나노입자를 가공제
Nanoparticles present possible dangers
- due to the high surface to volume ratio
pass through cell membranes in organisms
Smaller nanoparticles evinced increased cytotoxicity.
Self-assembly :
process that disordered system of components forms an organized structure or pattern
The device is switched on - >
the pump pushes ions across the lipid membrane,
remove large debris such as sticks, leaves, trash and other large particles
water stored in reservoirs for periods between a few days and many months to allow natural biological purification to take place
salts are treated with soda-ash (Na2CO3) to precipitate CaCO3 out utilizing the common-ion effect
chlorinated to minimize the growth of fouling organisms on the pipe-work and tanks
*’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
