free-molecular flow
1Free molecular flow — describes the fluid dynamics of gas where the mean free path of the molecules is larger than the size of the chamber or of the object under test. For tubes/objects of the size of several cm, these means pressures well below 10 3 torr. This is… …
2Molecular graphics — (MG) is the discipline and philosophy of studying molecules and their properties through graphical representation.[1] IUPAC limits the definition to representations on a graphical display device .[2] Ever since Dalton s atoms and Kekulé s benzene …
3Molecular dynamics — (MD) is a computer simulation of physical movements of atoms and molecules. The atoms and molecules are allowed to interact for a period of time, giving a view of the motion of the atoms. In the most common version, the trajectories of molecules… …
4Molecular motor — Molecular motors are biological molecular machines that are the essential agents of movement in living organisms. Generally speaking, a motor may be defined as a device that consumes energy in one form and converts it into motion or mechanical… …
5molecular beam — Physics. a stream of molecules freed from a substance, usually a salt, by evaporation and then passed through a narrow slit for focusing, for investigating the properties of nuclei, atoms, and molecules. Also called molecular ray. * * * ▪ physics …
6Software tools for molecular microscopy — There are a large number of software tools or software applications that have been specifically developed for the field sometimes referred to as molecular microscopy or cryo electron microscopy or cryoEM. Several special issues of the Journal of… …
7Central dogma of molecular biology — The central dogma of molecular biology was first articulated by Francis Crick in 1958[1] and re stated in a Nature paper published in 1970:[2] Information flow in …
8Air-free technique — Air free techniques refer to a range of manipulations in the chemistry laboratory for the handling of compounds that are air sensitive. These techniques prevent the compounds from reacting with components of air, usually water and oxygen; less… …
9History of molecular biology — The history of molecular biology begins in the 1930s with the convergence of various, previously distinct biological disciplines: biochemistry, genetics, microbiology, and virology. With the hope of understanding life at its most fundamental… …
