Uncoupling (measured as thermogenesis) is only observed when the cells are adequately stimulated, for example, by
norepinephrine
Inhibitors – purine nucleotide
Activators – Free fatty acids
Heat production
Changes in Membrane potential – especially
proton motive force ↓
Fatty acid anion transport
activators, inhibitors
2007년 논문에 의하면, 포유류의 UCP는 총 5종류(UCP1, UCP2, UCP3, UCP4, UCP5)가 있다. 이 중에서 생리적 기능에 대해 비교적 논란의 여지가 없는 것은 UCP1이고, UCP2와 UCP3는 생리적 기능이 계속해서 밝혀지고 있는 중이며, 나머지 UCP는 생리적 기능이 하나도 밝혀지지 않은 상태이다. 그래서 이 자료에선 UCP4, UCP5
(1)Place 0.75(∓0.001g) unknown sample in 250ml beaker
and add 100ml distilled water.
(2) Do Experiment in the same way with Experiment A.
(3) Calculate mass and percentage of Na2C2O4 in unknown oxalate. And Calculate ratio in the same way with Exp A.
oxide layer, it causes entire curve of graph to shift to the [Figure 12] C-V graph shift by direction of bias
side. These charges are generated by ions came in the process of deposition of oxide layer. When the charges exist in between the substrate and interface, the value of Vfb and C-V curve will shift by amount of the charge divided by Cox of Ci. The amount of shifting decreases as the posit

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
