  2. Electron-cloud effect - Wikipedia

    en.wikipedia.org/wiki/Electron-cloud_effect

    Electron clouds are created when accelerated charged particles disturb stray electrons already floating in the tube, and bounce or slingshot the electrons into the wall. These stray electrons can be photo-electrons from synchrotron radiation or electrons from ionized gas molecules.

  3. Atom - Wikipedia

    en.wikipedia.org/wiki/Atom

    The electron cloud is a region inside the potential well where each electron forms a type of three-dimensional standing wave—a wave form that does not move relative to the nucleus. This behavior is defined by an atomic orbital , a mathematical function that characterises the probability that an electron appears to be at a particular location ...

  4. Hyperfine structure - Wikipedia

    en.wikipedia.org/wiki/Hyperfine_structure

    In atomic physics, hyperfine structure is defined by small shifts in otherwise degenerate electronic energy levels and the resulting splittings in those electronic energy levels of atoms, molecules, and ions, due to electromagnetic multipole interaction between the nucleus and electron clouds.

  5. Quantum biology - Wikipedia

    en.wikipedia.org/wiki/Quantum_biology

    Quantum biology is the study of applications of quantum mechanics and theoretical chemistry to aspects of biology that cannot be accurately described by the classical laws of physics. [1] An understanding of fundamental quantum interactions is important because they determine the properties of the next level of organization in biological systems.

  6. Steric effects - Wikipedia

    en.wikipedia.org/wiki/Steric_effects

    The parent cyclobutadiene (R = H) readily dimerizes but the R = tert-butyl derivative is robust. [1]Steric effects arise from the spatial arrangement of atoms. When atoms come close together there is generally a rise in the energy of the molecule.

  7. Electron - Wikipedia

    en.wikipedia.org/wiki/Electron

    The electron (e −, or β − in nuclear reactions) is a subatomic particle with a negative one elementary electric charge. [13] Electrons belong to the first generation of the lepton particle family, [14] and are generally thought to be elementary particles because they have no known components or substructure. [1]

  8. List of effects - Wikipedia

    en.wikipedia.org/wiki/List_of_effects

    Electron-cloud effect (particle accelerators) (physics) Electroviscous effects (colloid chemistry) (surface chemistry) ELIZA effect (artificial intelligence) (human–computer interaction) (propositional fallacies) Embedding effect (environmental economics) EMC effect (particle physics) Emerson effect (photosynthesis)

  9. Resolution (structural biology) - Wikipedia

    en.wikipedia.org/.../Resolution_(structural_biology)

    In structural biology, resolution can be broken down into 4 groups: (1) sub-atomic, when information about the electron density is obtained and quantum effects can be studied, (2) atomic, individual atoms are visible and an accurate three-dimensional model can be constructed, (3) helical, secondary structure, such as alpha helices and beta sheets; RNA helices (in ribosomes), (4) domain, no ...
