the molecular separation
21molecular distillation — noun : distillation that is carried out under a high vacuum in an apparatus so designed as to permit molecules escaping from the warm liquid to reach the cooled surface of the condenser before colliding with other molecules and consequently… …
22molecular distillation — /məlɛkjələ dɪstəˈleɪʃən/ (say muhlekyuhluh distuh layshuhn) noun vacuum distillation in which the mean free path of the distillate molecules is of the same order as the distance between the heating and condensing surfaces; used for isotope… …
23Atomic vapor laser isotope separation — AVLIS Is an acronym which stands for atomic vapor laser isotope separation and is a method by which specially tuned lasers are used to separate isotopes of uranium using selective ionization of hyperfine transitions. In the largest technology… …
24Isotope separation — is the process of concentrating specific isotopes of a chemical element by removing other isotopes, for example separating natural uranium into enriched uranium and depleted uranium. This is a crucial process in the manufacture of uranium fuel… …
25Electrostatic deflection (molecular physics/nanotechnology) — In molecular physics/nanotechnology, electrostatic deflection is the deformation of a beam like structure/element bent by an electric field. It can be due to interaction between electrostatic fields and net charge or electric polarization effects …
