  2. Layered materials - Wikipedia

    en.wikipedia.org/wiki/Layered_materials

    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]

  3. Monolayer - Wikipedia

    en.wikipedia.org/wiki/Monolayer

    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.

  4. Intercalation (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Intercalation_(chemistry)

    An extreme case of intercalation is the complete separation of the layers of the material. This process is called exfoliation. Typically aggressive conditions are required involving highly polar solvents and aggressive reagents. [6]

  5. Substrate (materials science) - Wikipedia

    en.wikipedia.org/wiki/Substrate_(materials_science)

    Substrate is a term used in materials science and engineering to describe the base material on which processing is conducted. Surfaces have different uses, including producing new film or layers of material and being a base to which another substance is bonded.

  6. Layered double hydroxides - Wikipedia

    en.wikipedia.org/wiki/Layered_double_hydroxides

    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 ...

  7. Self-assembled monolayer - Wikipedia

    en.wikipedia.org/wiki/Self-assembled_monolayer

    Metal substrates for use in SAMs can be produced through physical vapor deposition techniques, electrodeposition or electroless deposition. [1] Thiol or selenium SAMs produced by adsorption from solution are typically made by immersing a substrate into a dilute solution of alkane thiol in ethanol, though many different solvents can be used [1] besides use of pure liquids. [16]

  8. Interface (matter) - Wikipedia

    en.wikipedia.org/wiki/Interface_(matter)

    The interface between matter and air, or matter and vacuum, is called a surface, and studied in surface science. In thermal equilibrium, the regions in contact are called phases, and the interface is called a phase boundary. An example for an interface out of equilibrium is the grain boundary in polycrystalline matter.

  9. Epitaxy - Wikipedia

    en.wikipedia.org/wiki/Epitaxy

    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.
