1. Background
Scent: Odor
The sense of smell gives rise to the perception of odors, mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, a small patch of tissue in back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. Each neuron has cilia in direct contact with air. The

intro
These days, it is important to study about the surface of the semiconductor and analyze its structure and composition. An EELS (electron energy loss spectroscopy) is one of the powerful tools for study the sample. One method to analyze the TEM data. It is the study of the vibrational motion of atoms and molecules on and near the surface by the analysis of the energy spectrum of low-energy
