Electrochemical Treatment of Tumors

This model incorporates the transport and electrolytic reaction in the treatment of tumor tissue. Oxygen evolution at the anode produces protons, which lowers the pH, while chlorine production also leads to lowered pH through the hydrolysis of chlorine. One effect of a low pH is the permanent destruction of haemoglobin in the tissue, resulting in the eradication of tumor tissue. This model ...

Current Distribution in a Chlor-Alkali Membrane Cell

The chlor-alkali membrane process is one of the largest in industrial electrolysis with the production of roughly 40 million metric tons of both chlorine and caustic soda per year. Chlorine is used predominantly for the production of vinyl chloride monomer, which in turn is used for the production of poly vinyl chloride (PVC). Current density in membrane-cell technology has increased ...

Thin Layer Chronoamperometry

The common electroanalytical method of exhaustive amperometric detection in a microscopic thin layer is modelled as a 1D-symmetric diffusion problem. The simulated result agrees with the analytical Cottrell equation at short times, and deviates as expected at long times when the diffusion layer spans the thin layer cell.

Zone Electrophoresis - new

Zone electrophoresis (ZE) is an electrophoretic separation technique, typically used for analyzing proteins, nucleic acids and biopolymers. During the process, different species in a sample are transported in a continuous electrolyte buffer system, subject to a potential gradient. Due to differences in the mobilities, the species in the samples will eventually separate into different, well ...
