Chinese economy and currency regime
Chinese economy had been controlled by the central government under the planned economy regime until 1979 (Morrison, 2007). In other words, most economic conditions used to be decided by the state in accordance with its policy, not by the market forces. From 1979, however, China has been experiencing huge innovation in its economic system until the present tim
Program (1) : Channels
Experiments (1-1) : Potassium Channels
A) The proability that the channel is open increases in a sigmoid manner with time. Explain why?
Potassium(K+) channel의 경우 Sodium channel(Na+)과 달리 inactivation gate가 없고 activation gate만 4개를 가지고 있으며, 이를 n gate라고 한다. 막전압의 변화는 세포막에 존재하는 전하를

① KM값과 KCl값을 각각 250 mM 로 할 경우에 세포 내외의 각 이온의 분포는 ?
평형에 이르면 전기적인 net force가 0일 것이므로 막 내외의 양이온과 음이온의 농도 값은 같을 것이다.

VLE란, 2가지 이상의 액체 물질을 일정 압력과 온도에서 일정 기간 동안 유지시켰을 시, 액체와 액체의 증기가 공존하여 이루는 평형상태를 뜻한다. 간단히 말해서 액상과 기상이 공존하는 상태를 말한다.
이러한 기∙액 상평형은 혼합물의 내부 성질을 파악하기 위해서 사용되며, 실
1. Introduction
대부분의 영역에서 과학이 해왔던 일은, 우리 주변에서 일어나는 일들을 어떻게 설명할 수 있는가에 초점을 두었었다. 이를 위해 복잡해 보이는 여러 가지 현상들을 가능한 한 간단한 형태로 바꾸어 기본적인 원리를 알아내고자 하는 작업들이 꾸준히 진행되어 왔었다. 화학의 영역도

4.1 RCA cleaning
RCA cleaning is a series of rinsing procedure prior to experiment with Si wafer. The purpose of the RCA clean is to remove organic contaminants (such as dust particles, grease or silica gel) from the wafer surface. There are three steps to be performed. The first step is to remove organic contaminant from surface of wafer. Second step is to remove any oxide layer
Acetone is the organic compound with the formula (CH3)2CO.
We have to use nearly pure acetone for organic solution.
Acetone is produced directly or indirectly from propylene.
After several processes.
Products we have are 40% of acetone and water solution.
How we get nearly pure acetone?
Factors to be considered:
Feasibility
Product value
Cost
Product quality
selectivity
