  2. Chemisorption - Wikipedia

    en.wikipedia.org/wiki/Chemisorption

    Chemisorption is a kind of adsorption which involves a chemical reaction between the surface and the adsorbate. New chemical bonds are generated at the adsorbent surface. Examples include macroscopic phenomena that can be very obvious, like corrosion [clarification needed], and subtler effects associated with heterogeneous catalysis, where the catalyst and reactants are in different pha

  3. Langmuir adsorption model - Wikipedia

    en.wikipedia.org/wiki/Langmuir_adsorption_model

    Thus, the use of alternative probe molecules can often result in different obtained numerical values for surface area, rendering comparison problematic. The model also ignores adsorbate–adsorbate interactions. Experimentally, there is clear evidence for adsorbate–adsorbate interactions in heat of adsorption data.

  4. Olfactory bulb - Wikipedia

    en.wikipedia.org/wiki/Olfactory_bulb

    The glomeruli layer of the olfactory bulb is the first level of synaptic processing. [1] The glomeruli layer represents a spatial odor map organized by chemical structure of odorants like functional group and carbon chain length. This spatial map is divided into zones and clusters, which represent similar glomeruli and therefore similar odors.

  5. Glia limitans - Wikipedia

    en.wikipedia.org/wiki/Glia_limitans

    These two parts of the glia limitans are continuous; however, convention dictates that the part that covers the surface of the brain is referred to as the superficialis, and the part that encloses the blood vessels within the brain is called the perivascularis.

  6. Transition state theory - Wikipedia

    en.wikipedia.org/wiki/Transition_state_theory

    It offers a concrete interpretation of the pre-exponential factor A in the Arrhenius equation; for a unimolecular, single-step process, the rough equivalence A = (k B T/h) exp(1 + ΔS ‡ /R) (or A = (k B T/h) exp(2 + ΔS ‡ /R) for bimolecular gas-phase reactions) holds. For a unimolecular process, a negative value indicates a more ordered ...

  7. Cerebrum - Wikipedia

    en.wikipedia.org/wiki/Cerebrum

    The cerebrum (pl.: cerebra), telencephalon or endbrain [1] is the largest part of the brain, containing the cerebral cortex (of the two cerebral hemispheres) as well as several subcortical structures, including the hippocampus, basal ganglia, and olfactory bulb. In the human brain, the cerebrum is the uppermost region of the central nervous system.

  8. Lindemann mechanism - Wikipedia

    en.wikipedia.org/wiki/Lindemann_mechanism

    Although the net formula for decomposition or isomerization appears to be unimolecular and suggests first-order kinetics in the reactant, the Lindemann mechanism shows that the unimolecular reaction step is preceded by a bimolecular activation step so that the kinetics may actually be second-order in certain cases. [7]

  9. Physisorption - Wikipedia

    en.wikipedia.org/wiki/Physisorption

    For chemisorption, changes in the electronic states may be detectable by suitable physical means, in other words, chemical bonding. Typical binding energy of physisorption is about 10–300 meV and non-localized. Chemisorption usually forms bonding with energy of 1–10 eV and localized.
