Transport phenomena have wide application. For example, in solid state physics, the motion and interaction of electrons, holes and phonons are studied under "transport phenomena". Another example is in biomedical engineering, where some transport phenomena of interest are thermoregulation, perfusion, and microfluidics. In chemical engineering ...
It is also utilized in the field of medicine, for example to allow for the administration of medicine across the blood–brain barrier via lipid nanoparticles. [2] The Trojan Horse effect is utilized by some antibiotics. By having the active compound bound to a mimic compound of molecules which are desirable to the bacteria. [3]
A transport coefficient measures how rapidly a perturbed system returns to equilibrium. The transport coefficients occur in transport phenomenon with transport laws J k = γ k X k {\displaystyle \mathbf {J} _{k}=\gamma _{k}\mathbf {X} _{k}}
Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
These are topics related to the transport phenomena encountered in physics and engineering. Subcategories. This category has the following 4 subcategories, out of 4 ...
As mentioned above, passive diffusion is a spontaneous phenomenon that increases the entropy of a system and decreases the free energy. [5] The transport process is influenced by the characteristics of the transport substance and the nature of the bilayer. The diffusion velocity of a pure phospholipid membrane will depend on: concentration ...

The spin Hall effect (SHE) is a transport phenomenon predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971. [ 1 ] [ 2 ] It consists of the appearance of spin accumulation on the lateral surfaces of an electric current -carrying sample, the signs of the spin directions being opposite on the opposing boundaries.
