CHE 241 Blood Pattern Analysis Labs


The CHE 241 Spring 2011 class working hard during their blood pattern analysis labs.  Students spent time evaluating how the angle of impact determines the shape of passive blood drops, how to use stringing methods to determine the point of origin and point of convergence of spatter patterns, and how cast-off stains are generated.  Everyone was a good sport during a somewhat messy lab!

New CHE 347 Anaglyph Lab – Fall 2011

Students will generate stereopairs using the scanning electron microscope (SEM) with an Everhart-Thornley detector.  The stereopairs can be combined into an anaglyph that appears 3D when viewed with chromatically opposed red and blue lenses.  The image at right depicts diatoms with a thin carbon coat (sample and coating courtesy of Jack Hietpas, Syracuse University).
