Materials
There can be carbons which are not contacted with conducting additives.
These carbons only occupies volume. ‘dead volume’
Stable conductivity can be achieved by coating
Advantages of Mild Oxidation of Graphite
What happens to Graphite?
Nanochannels or micropores are made.
Effects of Mild Oxidation.
Micropores acts as ‘reservoirs’ for lithium ions sto

`휴대폰 소재의 진화` 어디까지…
'스칸듐,탄소섬유,강화유리,옥수수 전분까지….'
휴대폰 소재가 진화하고 있다. 지금까지 휴대폰 외장재는 가공이 편리하고 색상 구현력이 뛰어난 플라스틱이나 알루미늄 합금 등이 주로 쓰였다. 하지만 외부 충격에 약하다는 단점이 지적되면서 최근

carbon nanotubes reach the lungs, they are much more toxic than carbon black and can be more toxic than quartz, which is considered a serious occupational health hazard in chronic inhalation exposures.
• If fine NT dusts are present in a work environment, exposure protection strategies should be implemented to minimize human exposures.
Strong chemical and materials hygiene.

carbon electrode coated with CNT–GOx composites
was applied as an anode in a model glucose/O2 biofuel cell
CNT-supported glucose oxidase (CNT–GOx) was examined in the presence of 1,4-benzoquinone (BQ)
To avoid the application of additional redox mediators, enzymes, which exibit redox properities and are able to directly exchange electrons with conducting materials, ar
