  2. Spot analysis - Wikipedia

    en.wikipedia.org/wiki/Spot_analysis

    Spot analysis, spot test analysis, or spot test is a chemical test, a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation. The development and popularization of the test is credited to ...

  3. Four-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Four-point_flexural_test

    The four-point flexural test provides values for the modulus of elasticity in bending , flexural stress , flexural strain and the flexural stress-strain response of the material. This test is very similar to the three-point bending flexural test. The major difference being that with the addition of a fourth bearing the portion of the beam ...

  8. Arago spot - Wikipedia

    en.wikipedia.org/wiki/Arago_spot

    The Arago spot is very sensitive to small-scale deviations from the ideal circular cross-section. This means that a small amount of surface roughness of the circular object can completely cancel out the bright spot. This is shown in the following three diagrams which are simulations of the Arago spot from a 4 mm diameter disc (g = b = 1 m):

  9. Dot blot - Wikipedia

    en.wikipedia.org/wiki/Dot_blot

    A dot blot (or slot blot) is a technique in molecular biology used to detect proteins. It represents a simplification of the western blot method, with the exception that the proteins to be detected are not first separated by electrophoresis. Instead, the sample is applied directly on a membrane in a single spot, and the blotting procedure is ...
