Triboelectric charging of insulating materials has traditionally been considered a physics problem, but chemistry is playing a rapidly increasing role. Several important advances have been made since the last reviews. These developments, together with description of the role of c...
The quantum hydrodynamic-like equations as a function of two real sets of variables (i.e., the 4x4 action matrix and the 4-dimensional wave function modulus vector) of the Dirac equation are derived in the present work. The paper shows that in the low velocity limit the equation...
