concrete method of construction is making thereby.
Advantage of RC (Reinforced Concrete) structure is as following.
1) high economic performance
2) because resources expense is inexpensive than steel-frame structure) corrosion resistance that prevent corrosion of interior reinforcing rod because is alkalinity is security
3) have excellent modeling.
4) ability that have high hardness an
We investigated graphene-based transparent electrodes for InGaN/GaN light emitting diodes(LED). Nano-dotted layer of Ag and Ni were inserted between p-GaN and graphene to achieve low contact resistance and high transmittance. Heat treated Ag layer/graphene had low contact resistance of 0.7~1.2Ω/cm2, and we could achieve better luminance for GaN-based LED. However, for patterned Ni layer/graphene
Concrete is cheap, easy to get anywhere and form to any shape.
- Since, money needed in framed construction in modern structures consist of 26~32% of all. and monet needed for concrete construction takes 30~35% if money takes in framed constructions, concrete is dense in construction fee.
- Stronger stress resistance in compression than other materials.
- Good Durability, Fire endurance, Wa
어떻게?
① Metal을 이용
☞ Contact Resistance ↓, but Transmittance ↓
② Graphene을 이용
☞ Transmittance ↑, but Contact Resistance ↑
③ Metal/Graphene layer를 이용
☞ Transmittance ↑, Contact Resistance ↓
④ Patterned metal + Graphene을 이용 !! ↕:Good
☞ Transmittance ↑↑, Contact Resistance ↓↓ ↕: Bad
Ⅰ. 보호기술과 저작권보호기술
저작권 보호기술은 저작권 관리기술에서 정의하는 일련의 원칙과 시나리오들을 강제화(Enforcement) 하는 기술로 이해할 수 있다. 시장에 등장한 대부분의 DRM제품들은 저작권 보호기술을 상품화한 것이며, 주요 업체들은 자사의 솔루션에 표준화 작업이 진행되고 있는
