Abstract
Laser의 원리를 이용한 thermal lens effect를 이해한다.
이를 적용한 기본적 실험을 통해 용매의 고유 성질인 heat capacity와 용질의 molar extinction coefficient를 구해보고, 그 결과를 분석해본다.
Laser의 실제 응
thermal resistance
Limitation of Commercialization
Life time
PC monitor’s lifetime is 100,000 hours.
But, lifetime of E-paper is only 10000 ~ 20000 hours .
Ability to color of E-paper
Limitation of color materialization.
Processes
Hard to materialize as printing method of roll-to-roll
Increase in lifetime
Prevention from penetration of water and moisture.
Formation o
in the gas's case.
이번 실험은 열공학에서 기본 성질인 온도를 측정하는 방법 중 한가지 이다. 그리고 각 이론 식에 대입하여 각 금속 시편의 열전도 계수를 계산해 본다.
This experiment is one of the way to measure the temperature in the Thermal engineering. and calculate Thermal conductivity of each metal specimen using the each method.
method, rapid thermal evaporation, sputter deposition, template-assisted growth, chemical vapor deposition (CVD)
A vapor trapping design to modify the CVD synthesis process to facilitate and control the introduction of n-type carriers.
A p–n heterojunction composed of ZnO nanowires and a p+ silicon chip was achieved without any adulteration.
I–V curve for the p–n het

thermal treatment can be classified into three groups: gasification, combustion and pyrolysis. In this study, we applied fast pyrolysis technique, one of pyrolysis methods, to convert woody biomass under various reaction temperatures. As products, we could obtain char, oil and gas. Higher reaction temperature favored for the production of gas and around 500℃, the production of bio-oil was optim
공법으로서 이 무렵 등장한 것으로는 콘크리트 블록의 생산과 보강블럭구조공법을 우선 들 수가 있고, 역T형 PC부재(prestress를 도입한 작은 단면의 T형 부재)와 콘크리트 Dome Block을 사용하여 조립되는 바닥 구조공법 등을 들 수가 있다. 그러나 이러한 구조공법들이 그 후 뿌리를 내리지 못하였다.
