Yesterday, Sept 08 2011, we (Francois and Tibi) had the second round of experiments for wet silver coating on glass. The goal was to control the quality of the coating by reducing the concentration of our solutions and the rate of mixing. Two experiments were performed in parallel. One was done in a large volume for batch processing, and the other one was done under the microscope in a drop, for coating individual optical fibers. For the large volume experiment we used a perfusion system (new feature) to inject the silver solution into a bath of glucose solution.
