Adsorption
Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface.

Contamination
Contamination is the presence of an unwanted constituent, contaminant or impurity in a material, physical body, natural environment, workplace, etc.
New!!: Langmuir (unit) and Contamination · See more »
Crystal
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
New!!: Langmuir (unit) and Crystal · See more »
Dimensional analysis
In engineering and science, dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities (such as length, mass, time, and electric charge) and units of measure (such as miles vs. kilometers, or pounds vs. kilograms) and tracking these dimensions as calculations or comparisons are performed.

Experiment
An experiment is a procedure carried out to support, refute, or validate a hypothesis.
New!!: Langmuir (unit) and Experiment · See more »
Gas
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).

Irving Langmuir
Irving Langmuir (January 31, 1881 – August 16, 1957) was an American chemist and physicist.

Kinetic theory of gases
The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant rapid motion that has randomness arising from their many collisions with each other and with the walls of the container.

Molecular mass
Relative Molecular mass or molecular weight is the mass of a molecule.
New!!: Langmuir (unit) and Molecular mass · See more »
Molecule
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.
New!!: Langmuir (unit) and Molecule · See more »
Monolayer
A monolayer is a single, closely packed layer of atoms, molecules, or cells.
New!!: Langmuir (unit) and Monolayer · See more »
Nanostructure
A nanostructure is a structure of intermediate size between microscopic and molecular structures.
New!!: Langmuir (unit) and Nanostructure · See more »
Number density
In physics, astronomy, chemistry, biology and geography, number density (symbol: n or ρN) is an intensive quantity used to describe the degree of concentration of countable objects (particles, molecules, phonons, cells, galaxies, etc.) in physical space: three-dimensional volumetric number density, two-dimensional areal number density, or one-dimensional line number density.
New!!: Langmuir (unit) and Number density · See more »
Pressure
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
New!!: Langmuir (unit) and Pressure · See more »
Proportionality (mathematics)
In mathematics, two variables are proportional if there is always a constant ratio between them.
New!!: Langmuir (unit) and Proportionality (mathematics) · See more »
Radiant exposure
In radiometry, radiant exposure or fluence is the radiant energy received by a surface per unit area, or equivalently the irradiance of a surface, integrated over time of irradiation, and spectral exposure or is the radiant exposure per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
New!!: Langmuir (unit) and Radiant exposure · See more »
Reactivity (chemistry)
In chemistry, reactivity is the impetus for which a chemical substance undergoes a chemical reaction, either by itself or with other materials, with an overall release of energy.
New!!: Langmuir (unit) and Reactivity (chemistry) · See more »
Second
The second is the SI base unit of time, commonly understood and historically defined as 1/86,400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each.
New!!: Langmuir (unit) and Second · See more »
Solid-state physics
Solid-state physics is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy.
New!!: Langmuir (unit) and Solid-state physics · See more »
Sticking coefficient
Sticking coefficient is the term used in surface physics to describe the ratio of the number of adsorbate atoms (or molecules) that adsorb, or "stick", to a surface to the total number of atoms that impinge upon that surface during the same period of time.
New!!: Langmuir (unit) and Sticking coefficient · See more »
Surface science
Surface science is the study of physical and chemical phenomena that occur at the interface of two phases, including solid–liquid interfaces, solid–gas interfaces, solid–vacuum interfaces, and liquid–gas interfaces.

Thermodynamic temperature
Thermodynamic temperature is the absolute measure of temperature and is one of the principal parameters of thermodynamics.
New!!: Langmuir (unit) and Thermodynamic temperature · See more »
Torr
The torr (symbol: Torr) is a unit of pressure based on an absolute scale, now defined as exactly of a standard atmosphere (101.325 kPa).
New!!: Langmuir (unit) and Torr · See more »
Ultra-high vacuum
Ultra-high vacuum (UHV) is the vacuum regime characterised by pressures lower than about 10−7 pascal or 100 nanopascals (10−9 mbar, ~10−9 torr).
