Definition of chemisorption in English:
chemisorption
noun ˌkɛmɪˈzɔːpʃ(ə)nˌkɛmɪˈsɔːpʃ(ə)n-ˈzôrp-
mass nounChemistry Adsorption in which the adsorbed substance is held by chemical bonds.
Example sentencesExamples
- Chemists make a distinction between chemical adsorption, or chemisorption, characterized by the formation of chemical bonds with the substrate, and physical adsorption or physisorption, which results from the van der Waals force.
- The authors write, ‘Both the physisorption and the chemisorption play important roles in optimizing the hydrogen storage.’
- These data support what has already been suggested: that the DOPA side-chain in proteins serves two important roles in adhesion-the formation of cross-links and interfacial complexes in chemisorption.
- This model is most appropriate when interactions between the MC and its environment are purely surface phenomena, as in the chemisorption of thiol molecules on the smooth surface of a gold-coated cantilever.
- Intact DOPA, particularly near the interface, may be essential for good chemisorption to polar surfaces.
Derivatives
adjective
Chemistry These findings indicate that in physiological conditions the divalent counterions are not chemisorbed on the surface of the DNA molecule but are confined in a narrow sheath.
Example sentencesExamples
- In both theories, the PAD is calculated for an isolated chemisorbed atom or surface molecule complex.
- The variants with one and two surface cysteines can be directly chemisorbed on bare gold.
- This resulted in a hydrophobic, self-assembled monolayer of octanethiol, chemisorbed to the gold-covered areas, whereas the mica regions remained uncovered.
- This invention relates to silver powders and more particularly to flake silver powders having oleic acid monolayer chemisorbed on the surface.
Origin
1930s: from chemi- + a shortened form of adsorption.
