The movement of a substance such as water vapor from regions of high concentration to regions of lower concentration
The intermingling of molecules of two or more substances When high temperature processes are done in diffusion tubes, the high temperature accelerates diffusion Typical diffusion furnace temperature is 950 degrees Centigrade, or 1742 degrees Fahrenheit
Physical process in which molecules move in space in the direction of their local concentration gradient In cellular systems, this results in their net translocation from the site of their production to that of their utilization Diffusion in aqueous solution is slow and may represent a rate limiting factor in heterogeneous catalytic systems operating at high rates of catalysis
The act of diffusing, or the state of being diffused; a spreading; extension; dissemination; circulation; dispersion
The movement of suspended or dissolved particles from an area of higher concentration to an area of lower concentration as the result of random movement of individual particles
a process by which substances, heat, or other properties of a medium are transferred from regions of higher concentration to regions of lower concentration
Process by which there is a net flow of matter from a region of high concentration to one of low concentration. It occurs fastest in liquids and slowest in solids. Diffusion can be observed by adding a few drops of food colouring to a glass of water. The scent from an open bottle of perfume quickly permeates a room because of random motion of the vapour molecules. A spoonful of salt placed in a bowl of water will eventually spread throughout the water
the process by which molecules move through their kinetic energy from an area of higher concentration to an area of lower concentration
The movement of a substance from an area of high concentration to an area of lesser concentration as a result of random movement
One of a series of steps in the fabrication of a semiconductor This step introduces a small amount of a chemical element, called impurity or dopant, into the substrate These steps will produce either N-type or P-type regions to create the function of a desired component on the chip
A material transport phenomena that occurs in solids, and is caused by the continual physical motion of atoms from one position to another This results in the flow of material from regions of high concentration to regions of low concentration
is a process by which the atmosphere being monitored is transported to the gas-sensing element by natural random molecular movement This movement is accelerated by thermal energy
the spread of social institutions (and myths and skills) from one society to another (physics) the process of diffusing; the intermingling of molecules in gases and liquids as a result of random thermal agitation
The outward spreading of a plume of liquid or gas from areas of greater concentration to areas of lesser concentration
The net movement of particles from a region of high concentration to an area of lower concentration, bought about by the kinetic energy of the particles
The movement of chemical species (ions or molecules ) under the influence of concentration difference The species will move from the high concentration area to the low concentration area till the concentration is uniform in the whole phase Diffusion in solutions is the most important phenomenon in electrochemistry, but diffusion will occur also in gases and solids
the net movement of gas molecules from areas with higher concentration of that gas to areas with lower concentration
a process by which substances, heat, or other properties of a medium are transferred from regions of higher concentrations to regions of lower concentration
the spread of social institutions (and myths and skills) from one society to another
the movement of individual molecules through a material The movement occurs because of the kinetic energy of the individual molecules, independent of airflow Kinetic energy increases as the temperature increases See Air barriers vs Vapor Barriers
is either characterized as molecular or turbulent Molecular diffusion results from the random motion of molecules and it leads to a homogenization of fluid properties if given enough time Turbulent diffusion involves motion that results from the random motion of small-scale coherent features These features, usually not resolved by measurements, are efficient stirrers and lead to ocean and atmospheric mixing rates that are much larger than those from molecular diffusion The modeling of turbulent diffusion is one of the outstanding problems in applied physics
The process of spontaneous intermixing of different substances due to molecular motion which tends to produce uniformity of concentration
The random movement of particles from an area of greater concentration to one of a lower concentration
The movement of gas molecules or aerosols into liquids, caused by a concentration gradient
a passive form of random movement in which areas of high chemical concentration gradually spread throughout an entire system, equalizing the chemical concentration over the system For example, the exchange of gases in the lungs occurs by simple diffusion across capillary walls
the act of dispersing or diffusing something; "the dispersion of the troops"; "the diffusion of knowledge"
The act of passing by osmosis through animal membranes, as in the distribution of poisons, gases, etc
The angular redistribution of radiation by a scattering, reflecting or refracting system, ideally producing an isotropic distribution of intensity The gradual mixing of the molecules of two or more substances, as a result of random thermal motion
the movement of particles from an area of higher concentration to an area of lower concentration
(physics) the process of diffusing; the intermingling of molecules in gases and liquids as a result of random thermal agitation
Unlike absorption, diffusion may go on after death, that is, after the blood ceases to circulate
A thin layer (usually micrometres thick) of metal usually placed between two other metals. It is done to act as a barrier to protect either one of the metals from corrupting the other
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is a process of passive transport (as opposed to active transport), with this passive transport aided by integral membrane proteins. Facilitated diffusion is the spontaneous passage of molecules or ions across a biological membrane passing through specific transmembrane integral proteins. The facilitated diffusion may occur either across biological membranes or through aqueous compartments of an organism
