Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals in the ultraviolet region. The oscillations can be described as an instability in the dielectric function of a free electron gas. The frequency depends only weakly on the ...
The Langmuir adsorption model explains adsorption by assuming an adsorbate behaves as an ideal gas at isothermal conditions. According to the model, adsorption and desorption are reversible processes. This model even explains the effect of pressure; i.e., at these conditions the adsorbate 's partial pressure is related to its volume V adsorbed ...
The probe is the spherical part, 50 mm in diameter and made from titanium with a surface coating of titanium nitride. A Langmuir probe is a device used to determine the electron temperature, electron density, and electric potential of a plasma. It works by inserting one or more electrodes into a plasma, with a constant or time-varying electric ...
Other academic advisors. Walther Nernst. Irving Langmuir (/ ˈlæŋmjʊər /; [2] January 31, 1881 – August 16, 1957) was an American chemist, physicist, and engineer. He was awarded the Nobel Prize in Chemistry in 1932 for his work in surface chemistry. Langmuir's most famous publication is the 1919 article "The Arrangement of Electrons in ...
Lewi Tonks. Lewi Tonks (1897–July 30, 1971) was an American physicist who worked for General Electric on microwaves, plasma physics and nuclear reactors. Under Irving Langmuir, his work pioneered the study of plasma oscillations. He is also noted for the noted for his discovery (with Marvin D. Girardeau) of the Tonks–Girardeau gas .
Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive ...
