To find the force of attraction between the pole faces, the standard virtual work approach is used: (4.3.4)Fx=−∂Wmag∂g=−B22μ0hl. In the case of an electric machine with smooth stator and rotor surfaces, the flux density normal to the ficititious “pole faces” is the radi...
Atomic Structure refers to the fundamental components of matter, namely atoms, which consist of a nucleus and orbiting electrons. The nucleus, acting as the center of an atom, is positively charged and has a much greater mass than the negatively charged electrons. Atoms are electrically neutral ...
The gravitation of a two-planet (as shown in Fig.1) is dependent on as Eq. (1). However, in this study, we find that the value of force\(\overrightarrow {F}\)will give less effective results than when using the moment\((M)\)as a parameter in the search process of the algorith...
Once the energy of the electromagnetic wave is reemitted by an atom, it travels through a small region of space between atoms. Once it reaches the next atom, the electromagnetic wave is absorbed, transformed into electron vibrations and then reemitted as an electromagnetic wave. While the ...
Think of what an atom is. Its point-sourced moving charge (proton, electron) that has an associated dimensional space-bubble (magnetism). How does nature express energy? Through vibration! Vibration is why things move from A to B, why they have spin or not, why things are high or low ...
Molybdenum sulphide (MoS2) possesses a typical graphite-like layered structure, where each Mo atom is covalently bonded to S atoms forming two-dimensional S-Mo-S sandwich like structure. Furthermore, these 2D layers are stack together by weak van der Waals attraction providing a large interlayer ...
The exponential factor represents the Boltzmann factor for the extra work necessary if a force fst is acting on the step23 when an atom of the area Ω2 solidifies. If c∞ > cst, adatoms flow into the step and the step becomes a sink of adatoms: solidification occurs. If c∞ < cst...
Indeed, adhesion of the nanoparticles on the surface of bacteria is mainly due to electrostatic force of attraction between oppositely charged surfaces. The bacterial cell wall is known negatively charged, and the metal nanoparticles have a positive surface charge. Then, the accumulated nanoparticles ...
All the all-atom MD simulations were based on a general AMBER force field [36] with the RESP charges [37] and were carried out using the Gromacs-4.6.7 software package [38]. The system is a relaxed liquid configuration at 298 K. The total run time was 10 ns NPT for the equilibrium...
