comparative form of low-emission: more low-emission

(physics) the instrument used in field emission microscopy

(physics) a technique that uses field emission of electrons or positive ions from the needle-shaped tip of an emitter to produce a magnified image of the emitter surface (showing each atom) on a fluorescent screen

The trading of emission allowances for carbon dioxide.

A vehicle that produces only carbon dioxide and water as its emissions and so does not pollute the air.

(medicine) A medical imaging technique which detects the gamma rays produced by positrons emitted from injected radionuclides.

(electronics) a flat panel display technology that uses large-area field electron sources to provide electrons that strike coloured phosphors to produce a colour image. In a general sense, an FED consists of a matrix of cathode ray tubes, each tube producing a single sub-pixel, grouped in threes to form red-green-blue (RGB) pixels.

plural of field emission microscope

plural of zero-emission vehicle

(physics, chemistry) A form of analytical spectroscopy that measures the radiation emitted at specific wavelengths by the atoms in a very hot sample
