If the substances have a similar charge, the two forces repel each others. If they have different charges, the two forces will attract each other. If there are no charges, there will be no reaction …

  • Stability and Synthesis of Dispersion

    The surfactant composite consisted of nonionic and anionic surfactants had a better ability to stabilize the emulsion than any surfactant used alone. When m (OP-10): m (SDS) was 2:3, the mass percent of the emulsion is more than 3%, and the best reaction stability and coalescence stability were obtained.

  • Dewatering Polyelectrolyte, DWPE,

    Bio-Gel P gels are autoclavable at pH 5.5–6.5 and operate over a pH range of 2–10 at room temperature. Flow rate and resolution increase with increasing temperature in the range of 4–80°C. The gels are compatible with dilute organic acids, 8 M urea, chaotropic agents, detergents, and miscible organic solvents.
