Intercalation is the reversible inclusion or insertion of a molecule (or ion) into layered materials with layered structures. Examples are found in graphite and transition metal dichalcogenides . [ 1 ] [ 2 ]
Intercalation may refer to: Intercalation (chemistry) , insertion of a molecule (or ion) into layered solids such as graphite Intercalation (timekeeping) , insertion of a leap day, week or month into some calendar years to make the calendar follow the seasons
Intercalation induces structural distortions. Left: unchanged DNA strand. Right: DNA strand intercalated at three locations (black areas). In biochemistry, intercalation is the insertion of molecules between the planar bases of deoxyribonucleic acid (DNA). This process is used as a method for analyzing DNA and it is also the basis of certain ...
In the area of solid state chemistry, graphite intercalation compounds are a family of materials prepared from graphite. In particular, the sheets of carbon that comprise graphite can be pried apart by the insertion (intercalation) of ions. The graphite is viewed as a host and the inserted ions as guests.
Titanium disulfide is an example of a layered material. The individual sheets are interconnected by van der Waals forces between the sulfide centers.. In material science, layered materials are solids with highly anisotropic bonding, in which two-dimensional sheets are internally strongly bonded, but only weakly bonded to adjacent layers. [1]
A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.
Ethidium bromide (or homidium bromide, [2] chloride salt homidium chloride) [3] [4] is an intercalating agent commonly used as a fluorescent tag (nucleic acid stain) in molecular biology laboratories for techniques such as agarose gel electrophoresis.
[9] [10] Intercalation of a metallo-intercalator creates less strain in the DNA duplex than insertion; metallo-insertors induce an untwist of the double helix and an opening of the phosphate backbone while metallo-intercalators marginally increase the rise and width of the major groove.
