A high zeta potential (lower than -30 mV or higher than 30 mV) can provide an electrostatic repulsion to avoid the aggregation of the particles[41].
With 22 fitted parameters, this cost function had four different terms which were designed to reflect, respectively, the Coulomb energy, the bond valence sum rule, a short-range repulsion (to keep atoms apart) and an angular function designed to maintain a more or less rigid octahedron around the Zr4+ and Ti4+ ions.
By doing so, it was then possible to identify which of the scores of the 23 project components showed an attraction or repulsion to each other and build a typology of case management projects.
Hoverboards have made headlines thanks to the Hendo board, which, like a maglev train, uses magnetic repulsion to float a couple of centimetres above a floor made of non-ferrous metal such as copper or aluminium.
In 1917, Einstein invented a fudge factor known as the cosmological constant, a sort of cosmic repulsion to balance gravity and keep the universe in balance.
There is at times a simultaneous attraction and repulsion to these forms.
In that year he inserted a mathematical fudge factor that came to be known as the cosmological constant into his equations of general relativity in order to stabilize the universe against collapse; Einstein's constant acted as a kind of cosmic repulsion to balance the gravitational pull of the galaxies on one another.
All materials display this type of weak repulsion to a magnetic field known as diamagnetism.
In a microeconomic scenario, Germaud and Fernandes (2003) consider that terrorism cause a contestation growth and repulsion to what is considered cultural enemies.
The Na+–Ins(1,3,4,5,6) P 5 association alleviates the inter-phosphate repulsion to a much greater extent in the 1a5e than in the 5a1e conformation.
