Ion channels ion-selective and fluctuate between open and closed states
The membrane potential in animal cells depends mainly on K⁺ leak channels and the K⁺ gradient across the plasma membrane
The resting potential decays only slowly when the Na⁺- K⁺ pump is stopped
The three-dimensional structure of a bacterial K⁺ channel shows how an ion channel can wo

③ Red, Green, and Blue LEDs for White Light Illumination
This LED application is structured by three chip(red, green, blue). Each chip emits three color. This structure has more strong light intensity than single chip WLED, but process is too complicate and not cost effective. And electron transfer is slow caused by 2-dimensiona
The optical microscope, often referred to as the "light microscope", is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although there are many complex designs w
