How rheometry works: The viscoelastic properties of a material are measured by a rheometer (Figure 1). A rheometer is a device used to measure how a liquid, suspension, or slurry flows in response to applied forces. In one type of method, a test specimen is placed in a die cavity, closed, and maintained at an...
How nanoindentation test method works A diamond indenter with a tip as small as 100 nm is used in this test (Figure 1). The diamond point is lowered and pressed into the test sample with a known load, for a specified dwell time, and the dimension of the resulting indentation is measured using a microscope....
How TMA works A sample is gradually heated to a specified temperature or until its properties change. The change in physical properties of the sample is measured in response to the change in temperature. Force can also be applied during heating to determine the response of the material under different modes. Strengths of TMA TMA...
How Spectral Ellipsometry (SE) works Light waves can oscillate in different directions. A polarized light oscillates in only one direction. Non Polarized light oscillates in many directions. The process of transforming unpolarized light into polarized light is known as polarization (Figure 1). In Spectral ellipsometry, polarized light is shone upon a sample to measure its...
