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 ...
NPTEL is the largest e-repository in the world of courses in engineering, basic sciences and selected humanities and management subjects. [1] The platform and materials have been jointly developed by Indian Institutes of Technology (IITs) and Indian Institute of Science. [2] The initiative is funded by the central Ministry of Education. The ...
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 ...
Figure 1. Elements used in one-dimensional models of viscoplastic materials. Viscoplasticity is a theory in continuum mechanics that describes the rate-dependent inelastic behavior of solids. Rate-dependence in this context means that the deformation of the material depends on the rate at which loads are applied. [1]

Characterization is the way materials scientists examine the structure of a material. This involves methods such as diffraction with X-rays , electrons or neutrons , and various forms of spectroscopy and chemical analysis such as Raman spectroscopy , energy-dispersive spectroscopy , chromatography , thermal analysis , electron microscope ...
Not all the clusters are stable. The stability of nanoclusters depends on the number of atoms in the nanocluster, valence electron counts and encapsulating scaffolds. [22] In the 1990s, Heer and his coworkers used supersonic expansion of an atomic cluster source into a vacuum in the presence of an inert gas and produced atomic cluster beams. [21]
Textile testing is the process of measuring the properties and performance of textile materials—textile testing includes physical and chemical testing of raw materials to finished products. Textile testing assists textile production in selecting various types of fibers and their transformation into yarn, fabric, and finished goods such as ...
