This page is used to show my work here in the Physics Department at the University of Washington. I am currently working in the Microstructural Kinetics Laboratory under the direction of Dr. Gerald T. Seidler. This page is mainly to show current images of Leisegange ring formation in different chemical systems we are working with. Our most current system is a Magnesium Hydroxide precipitate in 0.5 wt% agarose gel formed from the reaction of MgCl2 with NaOH by diffusion of NaOH into the MgCl2 gel.

Mg(OH)2 system

This picture is taken approximately 17 hours after the Sodium Hydroxide is poured on top of the MgCl2 agarose gel. Concentrations--1 N NaOH, 0.01 M MgCl2 0.5 wt% agarose with the MgCl2.

These two images show the same picture using two different lighting mechanisms. They are taken approximately 41 hours after time zero (same system as above).
