barrier diffusion
11Molecular diffusion — This article is about spontaneous dispersion of mass. For a more generic treatment of diffusion, see Diffusion. Diffusion from a microscopic and macroscopic point of view. Initially, there are solute molecules on the left side of a barrier… …
12Fick's laws of diffusion — For the technique of measuring cardiac output, see Fick principle. Molecular diffusion from a microscopic and macroscopic point of view. Initially, there are solute molecules on the left side of a barrier (purple line) and none on the right. The… …
13Gaseous diffusion — is a technology used to produce enriched uranium by forcing gaseous uranium hexafluoride, UF6, through semi permeable membranes. This produces a slight separation between the molecules containing uranium 235 and uranium 238. By use of a large… …
14Disease diffusion mapping — Disease diffusion occurs when a disease is transmitted to a new location.[1] It implies that a disease spreads, or pours out, from a central source.[2] The idea of showing the spread of disease using a diffusion pattern is relatively modern,… …

16Thermal barrier coating — Thermal barrier coatings are highly advanced material systems applied to metallic surfaces, such as gas turbine or aero engine parts, operating at elevated temperatures. These coatings serve to insulate metallic components from large and… …
17Surface-barrier transistor — The surface barrier transistor is a type of transistor developed by Philco in 1953 as an improvement to the alloy junction transistor and the earlier point contact transistor. Like the modern schottky transistor, it offered much higher speed than …
18Lateral diffusion — is the process whereby information can be spread from one node in a social network to another, often in a selective way, and can rapidly traverse an entire population, but preferentially to those nodes likely to be interested, or needing to… …
19gaseous diffusion — noun : diffusion of gases through a porous barrier at a rate of speed in direct proportion to the weight of the molecules, being used as the basis of a method of separating isotopes (as fissionable uranium 235 from the nonfissionable uranium 238) …
