WebMay 1, 2024 · In addition, Fig. 4 (a) shows that the milling force peaks fluctuate periodically, where every five peaks form a complete cycle. In each period, the second milling force peak is the largest and the other peaks increase linearly. This section will interpret the periodic fluctuation phenomenon based on the relation between RVE and feed per tooth. The electron distribution around an atom or molecule undergoes fluctuations in time. These fluctuations create instantaneous electric fields which are felt by other nearby atoms and molecules, which in turn adjust the spatial distribution of their own electrons. The net effect is that the fluctuations in electron … See more London dispersion forces (LDF, also known as dispersion forces, London forces, instantaneous dipole–induced dipole forces, fluctuating induced dipole bonds or loosely as van der Waals forces) are a type of See more The first explanation of the attraction between noble gas atoms was given by Fritz London in 1930.
