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 | Diffusion is an example of the law of large numbers, applied to chemistry.

Molecular diffusion will slowly evolve the parcel properties.

* 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 dispersion

Molecular mass is sometimes called molecular weight.

Orgel also participated in NASA's Viking Mars Lander Program as a member of the Molecular Analysis Team that designed the gas chromatography mass spectrometer instrument that robots took to the planet Mars.

Molecular mass is 576. 08, melting point 600 C ( with decomposition ), the substance is practically insoluble in water (< 0. 1g / 100 ml @ 20C ), but soluble in concentrated Sulphuric acid.

Molecular models typically describe atoms ( nucleus and electrons collectively ) as point charges with an associated mass.

The Molecular Disruption Device is a fictional weapon of mass destruction featured in the Ender's Game series of science fiction novels by Orson Scott Card.

Molecular biology has shown that the nicotinic and muscarinic receptors belong to distinct protein superfamilies.

Molecular evidence, that is, a specific pulsed-field gel electrophoresis profile, suggests that the distinct genotype of El Tor strain which appeared in Calcutta in 1993, may have spread to the African subcontinent.

Molecular studies have indicated that the eastern and western Atlantic populations have been genetically distinct for at least one million years, and could potentially be considered as separate subspecies.

Molecular and behavioral data suggest that it has no close relatives among living ducks and should be placed in a distinct genus ; it is possibly closest to such species as the Garganey and the Northern Shoveler.

Molecular studies suggest that the African and Madeiran populations are closely related and distinct from European populations of both subspecies, suggesting that Madeira was colonized from Africa and that the African population has a long history of isolation from European populations.

Molecular studies, however, indicate that it is a distinct species.

Molecular analyses of the ITS and 5S rDNA sequences indicate that T. hypoglaucum and T. doianum are not distinct from T. wilfordii, while T. regelii should be recognized as a separate species.

Molecular evidence suggests that the Phycodnaviridae may have evolved from the family Iridoviridae.

Molecular evidence indicates that the lineage of gibbons ( family Hylobatidae ) diverged from Great Apes some 18-12 million years ago, and that of orangutans ( subfamily Ponginae ) diverged from the other Great Apes at about 12 million years ; there are no fossils that clearly document the ancestry of gibbons, which may have originated in a so-far-unknown South East Asian hominoid population, but fossil proto-orangutans may be represented by Sivapithecus from India and Griphopithecus from Turkey, dated to around 10 million years ago.

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 orbitals are usually constructed by combining atomic orbitals or hybrid orbitals from each atom of the molecule, or other molecular orbitals from groups of atoms.

Molecular orbitals are obtained from the combination of atomic orbitals, which predict the location of an electron in an atom.

Molecular orbitals arise from allowed interactions between atomic orbitals, which are allowed if the symmetries ( determined from group theory ) of the atomic orbitals are compatible with each other.

Drexler argues that we may need to wait until our conventional nanotechnology improves before solving these issues: " Molecular manufacturing will result from a series of advances in molecular machine systems, much as the first Moon landing resulted from a series of advances in liquid-fuel rocket systems.

Molecular studies, however, have shown that the Cetacea descend from the Artiodactyl ancestors, although the precise phylogeny within the order remains uncertain.

A study conducted by the Centre for Cellular and Molecular Biology in 2009 ( in collaboration with Harvard Medical School, Harvard School of Public Health and the Broad Institute of Harvard and MIT ) analyzed half a million genetic markers across the genomes of 132 individuals from 25 ethnic groups from 13 states in India across multiple caste groups.

Molecular excitons have several interesting properties, one of which is energy transfer ( see Förster resonance energy transfer ) whereby if a molecular exciton has proper energetic matching to a second molecule's spectral absorbance, then an exciton may transfer ( hop ) from one molecule to another.

Molecular analysis suggests that the hexapods diverged from their sister group, the Anostraca ( fairy shrimps ), at around the start of the Silurian period-coinciding with the appearance of vascular plants on land.

") Molecular phylogenetics have clarified the relatedness of some associated genera, and at least nine genera that were previously included in Cornaceae have been eliminated from the order Cornales entirely, but the circumscription of Cornaceae is still unclear.

Molecular clock and fossil dating suggest echidnas split from platypuses 19 – 48 million years ago.

Molecular data indicate Vespertilionidae diverged from Molossidae in the early Eocene period.

Molecular genetics study suggests that surviving Amerindian populations derived from a theoretical single founding population, possibly from only 50 to 70 genetic contributors Preliminary research, restricted to only 9 genomic regions ( or loci ) have shown a genetic link between original Americas and Asia populations.
