Fizeau–Foucault apparatus - Wikipedia

In 1850 and in 1862, Léon Foucault made improved determinations of the speed of light substituting a rotating mirror for Fizeau's toothed wheel. (Figure 2) The apparatus involves light from slit S reflecting off a rotating mirror R, forming an image of the slit on the distant stationary mirror M, which is then reflected back to reform an image of the original slit.

How to disperse and stabilize pigments

This is usually accomplished by mechanical action provided by high impact mill equipment. In the grinding stage, the cohesive forces inside the agglomerates have to be overcome. Energy is added to the system and therefore smaller particles (with a larger interface to the resin solution) are formed. This results in loosened inter-particle contact durability, that eases the destruction of ...

It is not truly random as it does not break those bonds near an α-1 – 6 branch point. Because of its attack pattern, each break dramatically reduces the size of the resulting dextrin. As a result the viscosity of the starch-water paste decreases rapidly. This is why α-amylase is sometimes referred to as the liquefying enzyme. Because of the rapid decrease in viscosity with each bond broken ...
