Ⅱ. 나노공정의 분야
나노 공정의 경우 나노 자체의 학문이 단독으로서 사용되기보다는 NT/BT/IT/EI(환경에너지 기술) 등을 전반적으로 아우르는 융합 기반기술(Platform technology)에 쓰이며 이를 BENIT 융합이라고 부른다. 현재의 산업 현장에서는 주로 반도체 분야, 의료분야에서 많이 쓰이는 공정이다.

Regulation of IT Risk
In order to regulate the IT risk, governments work to address threat to computer crime. For example, representatives of 29 countries - including Canada, Japan and the U.S. – signed the Council of Europe Cybercrime convention in 2001. The convention deals with substantive and procedural cybercrime law. The substantive defines the following activities as crimina
Supplying energy for stable is the basis of national survival and economic growth. So this is very important.
Fuel cell is worthy of notice other alternative energy.
It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.
Fuel cells are direct energy conversion into electricity. So High electric conversion eff

For comparative purposes the corresponding peak-to-background ratios were: 4.4, 7.1 and 7.9 for 5kV, 10kV and 15kV, respectively. In addition to Nb, other elemental peaks could be detected from the surrounding materials. The Al and Si peaks were generated from the holder (the O peak was visible due to oxidation of the holder itself), the Ni peak originated from the sample grid and the extraction
Theory
In general, preparation methods for nanoparticles make use of capping agents, such as surfactants, polymers or biomaterial, in order to confine the growth. Occasionally, the selective or preferential adsorption of capping agents onto particular crystallograp- hic facets during the growth stage permits diverse shapes to be produced, for example triangles, hexagons, disks, rods and multi
