  2. Characterization (materials science) - Wikipedia

    en.wikipedia.org/wiki/Characterization...

    The characterization technique optical microscopy showing the micron scale dendritic microstructure of a bronze alloy. Characterization, when used in materials science, refers to the broad and general process by which a material's structure and properties are probed and measured. It is a fundamental process in the field of materials science ...

  3. Polymer characterization - Wikipedia

    en.wikipedia.org/wiki/Polymer_characterization

    The characterization of mechanical properties in polymers typically refers to a measure of the strength, elasticity, viscoelasticity, and anisotropy of a polymeric material. The mechanical properties of a polymer are strongly dependent upon the Van der Waals interactions of the polymer chains, and the ability of the chains to elongate and align ...

  5. Characterization of nanoparticles - Wikipedia

    en.wikipedia.org/wiki/Characterization_of_nano...

    The characterization of nanoparticles is a branch of nanometrology that deals with the characterization, or measurement, of the physical and chemical properties of nanoparticles.,. [1] Nanoparticles measure less than 100 nanometers in at least one of their external dimensions, and are often engineered for their unique properties.

  6. Size-exclusion chromatography - Wikipedia

    en.wikipedia.org/wiki/Size-exclusion_chromatography

    Size-exclusion chromatography, also known as molecular sieve chromatography, [1] is a chromatographic method in which molecules in solution are separated by their shape, and in some cases size. [2] It is usually applied to large molecules or macromolecular complexes such as proteins and industrial polymers . [ 3 ]

    en.wikipedia.org/wiki/Instrumental_chemistry

    [1] [2] These methods can be categorized according to which aspects of the cell are controlled and which are measured. The three main categories are potentiometry (the difference in electrode potentials is measured), coulometry (the cell's current is measured over time), and voltammetry (the cell's current is measured while actively altering ...

  8. Temperature-programmed reduction - Wikipedia

    en.wikipedia.org/wiki/Temperature-programmed...

    Temperature-programmed reduction is a technique for the characterization of solid materials and is often used in the field of heterogeneous catalysis to find the most efficient reduction conditions, [1] an oxidized catalyst precursor is submitted to a programmed temperature rise while a reducing gas mixture is flowed over it.

  9. Energy-dispersive X-ray spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Energy-dispersive_X-ray...

    Energy-dispersive X-ray spectroscopy (EDS, EDX, EDXS or XEDS), sometimes called energy dispersive X-ray analysis (EDXA or EDAX) or energy dispersive X-ray microanalysis (EDXMA), is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on an interaction of some source of X-ray excitation and ...
