As the pH value of the medium increases, the carboxylic acid groups become ionized and the electrostatic repulsion
between the molecular chains is predominated, which leads to the network more expanding.
Most likely, in this pH range macromolecules are straightened by electrostatic repulsion
of ionized carboxyl groups.
The stability of colloidal dispersion is controlled by steric or electrostatic repulsion
forces between particles.
6), the net negative charge on casein is reduced, which decreases electrostatic repulsion
between charged groups, including the phosphoserine residues that are exposed when the CCP is solubilized.
It requires breaking through the barrier of electrostatic repulsion
at larger scales in the atom and then using the attractive forces binding the nucleus to lasso the two nuclei together.
If both of these needs are met, then electrostatic repulsion
will take place between approaching particles and stability can be achieved," he states.
Because of the non-charged backbone, PNA probes--unlike DNA probes--do not encounter electrostatic repulsion
, allowing them to hybridize rapidly and tightly to nucleic-acid targets.
The process negatively charges Cryptospordium oocysts, causing it to charge near neutral, thereby eliminating the natural electrostatic repulsion
instead of repelling sand grains, a limitation of older sand filtration technology.
The concentration of citrus fiber had no effect on droplet size at pH 7 due to the electrostatic repulsion
between the negatively charged WPI and citrus fiber molecules.
The absence of flocculation of cationic AKD by cPAM proves that cPAM does not adsorb onto AKD stabilized by cationic starch, presumably because electrostatic repulsion
prevents cPAM adsorption on AKD.
It is related to the electrostatic repulsion
between uniformly charged particles, that causes stabilisation of the system.
The larger the size of the zeta potential (either positive or negative), the greater the electrostatic repulsion
will be between particles.
