Zeta potential is a key indicator of the stability of colloidal dispersions and nanoparticle suspensions. It measures the electrical potential difference between the bulk of the liquid and the ...

The zeta potential of polyethylenimine (PEI) is measured as a function of polymer concentration with the SZ-100 Nanoparticle Analyzer. There is a negative relationship between Zeta potential and ...

However, within the range of sizes normally encountered within water and waste water processes (< 1000 µm), surface forces play a vital role in controlling the removal characteristics of the system.

When a particle is immersed in a fluid, a range of processes causes the interface to become electrically charged. Some of the most commonly found charging mechanisms include adsorption of charged ...

The building blocks of proteins are amino acids. Each protein molecule often contains 300 or more amino acids, and proteins have 20 different amino acids commonly found within them. This means that ...

Formulation development is an important activity for a wide range of industries, from paints and coatings to pharmaceuticals. In the UK alone, it has been estimated that sales of formulated products ...

The ions and solvent in the shear layer travel in the medium as a unified whole when subjected to external force (i.e., electric field force). The potential defined at the slipping plane is known as ...

Malvern has announced it will be holding a new webinar to explain the use of electrophoretic light scattering (ELS) to measure the electrophoretic mobility of particles or molecules in a solution.
