June 2005 Featured on the Cover
The cover depicts a light scattering experiment using low-cost lasers. Red and violet laser beams are focused into a cuvette containing growing colloidal sulfur particles. Two photodiode detectors (not shown in photograph), situated at right angles to the laser beams and fitted with appropriate optical filters, are used to simultaneously monitor light scattering of the two colors of light. A computer interface may be used to monitor the photodiode signals and to study the reaction kinetics. See the article  "Monitoring Particle Growth: Light Scattering Using Red and Violet Diode Lasers" by Heejoon Ahn and James E. Whitten.
