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 ...
The intercalation compounds graphite bisulfate and graphite perchlorate can be prepared by treating graphite with strong oxidizing agents in the presence of strong acids. In contrast to the potassium and calcium graphites, the carbon layers are oxidized in this process:
[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.
Intercalation or embolism in timekeeping is the insertion of a leap day, week, or month into some calendar years to make the calendar follow the seasons or moon ...
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 ...
