Sentences with phrase «electrostatic repulsion»
"Electrostatic repulsion" refers to a force that pushes two or more charged particles away from each other due to their opposite charges. It is like when two magnets with the same poles (either two north poles or two south poles) get close to each other and push apart instead of sticking together. Full definition

For instance, Badawy et al. showed that negatively charged silver nanoparticles did not overcome electrostatic repulsion barrier towards similar charged bacillus species [28].
Mark Fitzgerald and Tim Armstrong at the Measurement Standards Laboratory in Lower Hutt, New Zealand, counterbalanced the gravitational attraction in their apparatus with a delicate electrostatic repulsion, which they in turn measured precisely.
Others expect electrostatic repulsion from the electrons to be the main driving force.
Huge densities and temperatures (millions of degrees, hotter even than the Sun's core) are required to overcome the electrostatic repulsion between the positively charged nuclei involved.
After accounting for the electrostatic repulsion and other forces, they found that the remaining force on the beads followed the force law for an ideal spring — whose force is proportional to how far it is extended — to very high accuracy.
Most of the topological materials studied so far — including those in Bernevig's atlas — have been relatively easy to understand, because the electrons inside them feel very little of each other's electrostatic repulsion.
Such forces are known — for instance, objects can be levitated using magnetic or electrostatic repulsion.
«If we can take advantage of this electrostatic repulsion, it could improve the diagnosis and treatment of certain bacterial infections.»
Research in the UCR School of Medicine laboratory of David Lo found that certain cells of the epithelium have a potentially important role in immune surveillance — creating an electrostatic repulsion field to microbial invasion.
These binding events can be impaired by the electrostatic repulsion of the negatively charged cell with the virus.
