An exciton is a bound state of an electron and hole which are attracted to each other by the electrostatic Coulombic force.
The exciton diffuses to around by chemical potential.
The lifetime <<1 nano seconds
The average distance <<10 nanometer.
The exciton diffuses to the interface between two layers
The exciton is saparated by an electron an

The fMRI, on the other hand, uses a giant magnet to track the blood flow throughout the brain as test subjects respond to visual, audio, or even taste cues.

In fabrication of MWCNT based glucose enzyme sensor, MWCNTs were grown on the sensing chip of which detection is for obtaining the electrical signal of the input source counting the difference from the original value which is read on the reference electrode. 10ml glucose oxidase was prepared in a standard of 0.4mg/ml solution. On this CNT-grown area, place some of this glucose oxida
