1Chemical imaging — (as quantitative chemical mapping) is the analytical capability to create a visual image of components distribution from simultaneous measurement of spectra and spatial, time informations.[1][2] The main idea for chemical imaging, the analyst may …
2chemical sense — n a nervous mechanism for the physiological reception of and response to chemical stimulation specif the central nervous process (as in smelling and tasting) initiated by excitation of special receptors sensitive to chemical substances in… …
3chemical bonding — ▪ chemistry Introduction any of the interactions that account for the association of atoms into molecules, ions, crystals, and other stable species that make up the familiar substances of the everyday world. When atoms approach one another …
4Chemical synapse — This article is about chemical synapses of the nervous system. For other uses, see Synapse (disambiguation). Illustration of the major elements in chemical synaptic transmission. An electrochemical wave called an action potential travels along… …
5chemical sense — noun : a nervous mechanism for the physiological reception of and response to chemical stimulation; specifically : the central nervous process (as in smelling and tasting) initiated by excitation of special receptors sensitive to chemical… …
6Excitation wavelength — The excitation wavelength describes the light shone on a sample to transfer energy to ( to excite ) a light reactive chemical group in any compound. Its unit is usually given in nanometers (nm). An example is the green fluorescent protein (GFP),… …
7excitation-contraction coupling — the coupling of the action potential to muscle constriction by means of calcium ions which diffuse rapidly into the myofibrils and catalyze the chemical reactions that promote the contractile sliding of actin and myosin filaments …
8Plasma-enhanced chemical vapor deposition — PECVD machine at LAAS technological facility in Toulouse, France. Plasma enhanced chemical vapor deposition (PECVD) is a process used to deposit thin films from a gas state (vapor) to a solid state on a substrate. Chemical reactions are involved… …
9Collisional excitation — is a process in which the translational energy of a collision partner is converted into the internal energy of a reactant species. Astronomy In astronomy, collisional excitation gives rise to spectral lines in the spectra of astronomical objects… …
10nerveimpulse — nerve impulse n. A wave of physical and chemical excitation along a nerve fiber in response to a stimulus, accompanied by a transient change in electric potential in the membrane of the fiber. * * * …
