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] Model of intercalation of potassium into graphite
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 ...
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
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.
[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.
Epiboly in zebrafish is the first coordinated cell movement, beginning at the dome stage late in the blastula period and continuing throughout gastrulation. [3] At this point the zebrafish embryo contains three portions: an epithelial monolayer known as the enveloping layer (EVL), a yolk syncytial layer (YSL) which is a membrane-enclosed group of nuclei that lie on top of the yolk cell, and ...

Intercalation is a special case of interbedding where a layer is variably inserted into an already existing sequence; or where two separate depositional environments ...
