Molecular diffusion, often called simply diffusion, is the thermal motion of all ( liquid or gas ) particles at temperatures above absolute zero.

Molecular diffusion is typically described mathematically using Fick's laws of diffusion.

* Molecular diffusion of gases

Molecular diffusion from a microscopic and macroscopic point of view.

** Molecular diffusivity ( often called " diffusion coefficient ")

Molecular diffusion will slowly evolve the parcel properties.

* Molecular diffusion

* Molecular diffusion, spontaneous dispersion of mass ( distinct from migration, caused by an external force )

* Molecular diffusion

Molecular diffusion controls mixing of soluble organic compounds into groundwater and transport of oxygen from underlying groundwater or the capillary fringe of the groundwater surface to micro-organisms capable of catabolizing dissolved organic compounds remaining in the effluent plume.

* Molecular diffusion

Molecular diffusion in tissues is not free, but reflects interactions with many obstacles, such as macromolecules, fibers, membranes, etc.

Molecular gastronomy includes the study of how different cooking temperatures affect egg ( food ) | eggs, and their viscosity, their surface tension, and different ways of introducing air into them.

Molecular absorption, in contrast, is much broader, so that it is more likely that some molecular absorption band will overlap with an atomic line.

She is the head of a research group, which is located in the Weatherall Institute of Molecular Medicine and working on a wide range of biological disciplines encompassing molecular biology, biochemistry, cellular immunology and intracellular neurophysiology.

* Molecular biology is the study of molecular underpinnings of the process of replication, transcription and translation of the genetic material.

Molecular distillation is vacuum distillation below the pressure of 0. 01 torr.

Molecular distillation is used industrially for purification of oils.

Molecular evidence suggests that between 8 and 4 million years ago, first the gorillas, and then the chimpanzees ( genus Pan ) split off from the line leading to the humans ; human DNA is approximately 98. 4 % identical to that of chimpanzees when comparing single nucleotide polymorphisms ( see human evolutionary genetics ).

Molecular oxygen ( O < sub > 2 </ sub >) is an extremely efficient quencher of fluorescence just because of its unusual triplet ground state.

Molecular orbitals ( MOs ) represent regions in a molecule where an electron is likely to be found.

For instance, polyethylene ( PE ) is a cheap, low friction polymer commonly used to make disposable shopping bags and trash bags, and is considered a commodity plastic, whereas medium-density polyethylene ( MDPE ) is used for underground gas and water pipes, and another variety called Ultra-high Molecular Weight Polyethylene UHMWPE is an engineering plastic which is used extensively as the glide rails for industrial equipment and the low-friction socket in implanted hip joints.

Molecular nanotechnology ( MNT ) is a technology based on the ability to build structures to complex, atomic specifications by means of mechanosynthesis.

Molecular surgical tools, guided by molecular computers and injected into the blood stream could find and destroy cancer cells or invading bacteria, unclog arteries, or provide oxygen when the circulation is impaired.

Molecular nanotechnology is one of the technologies that some analysts believe could lead to a Technological Singularity.

* The primary technical reference work on this topic is Nanosystems: Molecular Machinery, Manufacturing, and Computation, an in-depth, physics-based analysis of a particular class of potential nanomachines and molecular manufacturing systems, with extensive analyses of their feasibility and performance.

Nanosystems is closely based on Drexler's MIT doctoral dissertation, " Molecular Machinery and Manufacturing with Applications to Computation ".

Molecular mass is sometimes called molecular weight.

Molecular hydrogen is difficult to detect by infrared and radio observations, so the molecule most often used to determine the presence of H < sub > 2 </ sub > is CO ( carbon monoxide ).

Molecular mechanics simulations, for example, use a single classical expression for the energy of a compound, for instance the harmonic oscillator.

See, for example, the Molecular Genealogy Research Project.

He'd also seen that the absorption behavior of molecules is quite different from that of the atoms composing the molecules — for example the gas nitric oxide ( NO ) absorbed more than a thousand times more infrared radiation than either nitrogen ( N < sub > 2 </ sub >) or oxygen ( O < sub > 2 </ sub >).< ref > Contributions to Molecular Physics in the Domain of Radiant Heat, pp. 80 – 81.

Molecular assemblers are a popular topic in science fiction, for example, the matter compiler in The Diamond Age and the cornucopia machine in Singularity Sky.

Sometimes divisions may be finer: for example, Harvard University has separate departments of Organismic and Evolutionary Biology, Molecular and Cellular Biology, and Chemistry and Chemical Biology.

For example, Molecular Ecology, Proceedings of the Royal Society of London Series B, The American Naturalist and Theoretical Population Biology have overlap with ecology and other aspects of organismal biology.

or by electronic locking., as for example is done in the Noise-Immune Cavity-Enhanced Optical-Heterodyne Molecular Spectroscopy ( NICE-OHMS ) technique.

JUMBO began life as the Java Universal Molecular Browser for Objects but is now a Java library that supports validation, reading and writing of CML as well as conversion of several legacy formats to CML and, for example, a reaction in CML to an animated SVG representation of the reaction.

UCLA for example, features an HTS laboratory ( Molecular Screening Shared Resources ( MSSR, UCLA ) which can screen more than 100, 000 compounds a day on a routine basis.

Molecular nanotechnology, for example, could convert garbage in landfills into useful materials and products, while biotechnology could lead to novel microbes that devour hazardous waste.

Molecular Borromean rings are an example of a mechanically-interlocked molecular architecture in which three macrocycles are interlocked in such a way that breaking any macrocycle allows the others to disassociate.
