the wermlandite group, with a layer spacing of ~11 Å, in which cationic complexes occur with anions between the brucite-like layers; and; the hydrocalumite group, with M 2+ = Ca 2+ and M 3+ = Al 3+, which contains brucite-like layers in which the Ca:Al ratio is 2:1 and the large cation, Ca 2+, is coordinated to a seventh ligand of 'interlayer ...
Hydrotalcite, or formerly also völknerite, [6] is a layered double hydroxide (LDH) of general formula Mg 6 Al 2 CO 3 (OH) 16 ·4 H 2 O, whose name is derived from its resemblance with talc and its high water content. Multiple structures containing loosely bound carbonate ions exist.
Different forms of intrusions, based on the chemical makeup of the intrusion, are defined as: [9] Aurivillius phase: the intruding layer is composed of a [Bi 2 O 2] 2+ ion, occurring every n ABO 3 layers, leading to an overall chemical formula of [Bi 2 O 2]-A (n−1) B 2 O 7. Their oxide ion-conducting properties were first discovered in the ...
A strong base is a basic chemical compound that can remove a proton (H +) from (or deprotonate) a molecule of even a very weak acid (such as water) in an acid–base reaction. Common examples of strong bases include hydroxides of alkali metals and alkaline earth metals, like NaOH and Ca(OH)
LiHMDS is often used in organic chemistry as a strong non-nucleophilic base. [3] Its conjugate acid has a pK a of ~26, [4] making it is less basic than other lithium bases, such as LDA (pK a of conjugate acid ~36). It is relatively more sterically hindered and hence less nucleophilic than other lithium bases.
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.
A Langmuir monolayer or insoluble monolayer is a one-molecule thick layer of an insoluble organic material spread onto an aqueous subphase in a Langmuir-Blodgett trough. Traditional compounds used to prepare Langmuir monolayers are amphiphilic materials that possess a hydrophilic headgroup and a hydrophobic tail.
The relative orientation(s) of the epitaxial layer to the seed layer is defined in terms of the orientation of the crystal lattice of each material. For most epitaxial growths, the new layer is usually crystalline and each crystallographic domain of the overlayer must have a well-defined orientation relative to the substrate crystal structure.
