②White emission using mixtures of CdSe quantum dots and PMMA as a phosphor
This paper explain WLED that have mixture stucture (one single chip(emit blue light) and cdse/PMMA quantum dots). CdSe quantum dots are synthesized by the wet chemical method using CdO and Se powder as precursor. And they control the size of quantum dot and mix the phospors(PMMA).
These quantum dots have three differe
The aforementioned situation was the context in which Stupak confronted in pursing his pro-life objectives. The main source of the crucial leverage Stupak and his dozen allies were able to exert was the thin margin of victory for the health care reform. The House version (H.R. 3962) of health reform which included the Stupak-Pitts Amendment passed in the House only by a margin of 5 votes in Novem
2.5.1 고분자 전해질 막
고분자전해질 연료전지의 전해질은 H⁺를 전달하는 고분자 이온교환막을 사용한다. 고분자막은 anode와 cathode사이에서 수소이온의 전달체 역할을 하는 동시에 산소와 수소의 접촉을 막는 역할도 한다. 따라서 고분자 전해질 막은 수소이온전도성은 높아야 하는 대신 전자의

2.3 C-V graph
The measured MOS capacitance (called gate capacitance) varies with the applied gate voltage.
① Measurement of C-V characteristics
-Apply any DC bias, and superimpose a small (15 mV) ac signal
-Generally measured at 1 MHz (high frequency) or at variable frequencies between 1KHz to 1 MHz
-The dc bias VG is slowly varied to get quasi-continuous C-V characteristics

oscillator. The measurement of the resonator itself shows that the
suggested resonator provides a higher loaded quality factor with
reduced circuit area compared to the conventional hairpin
resonator. The oscillators are designed to operate at 9.2 GHz
using the conventional and novel hairpin resonators, to compare

A filter is widely used in overall RF system. There are many species and structures in filter. A filter seems to be simple, but there are many considerations to design filter. In this paper, we design microstrip bandpass filter which has bandwidth of 500 MHz and center frequency of 2.5 GHz. Alumina is used as substrate, and chromium is used as conductor. Final results are achieved as follows. Ins
