...JL Peterson, DCrim Walter McCrone was not only a remarkable forensic microscopist, but also a skilled grants man and devoted scientific professional. This article briefly recounts his activities in the1970s and 80s where he played a major role in securing grant funds to sponsor microscopy training...

... the strength of an association or an exclusion based upon comparisons of non-component debris particles and fibers can be made by reference to the criteria for reaching a conclusion. The criteria can be tested via Bayes' Theorem. The analysis itself is based primarily upon light microscopy, although other...

... filters. These materials were examined by scanning electron microscopy/energy-dispersive X-ray analysis. Calcium-phosphorous (bone) particles were detected on the 9-mm Smith & Wesson pistol, on two casings found at the scene, and on one of the revolvers. Two of the calcium-phosphorous particles...

...MW Tungol, M.F.S.; A Montaser, Ph.D. Infrared (IR) microscopic analysis was performed in tandem with traditional techniques of fiber analysis in case studies in order to determine the feasibility of IR microscopy as a routine technique for fiber analysis. All fibers which were comparable by visual...

... for comparison of the trace amounts of lipstick which usually occur in actual casework. Microspectrophotometry and scanning electron microscopy (SEM), in combination with energy-dispersive spectroscopy (EDS) were evaluated for comparison of minute lipstick samples. Microspectrophotometry proved very promising...

A series of calcium phosphate standards having calcium/phosphorus (Ca/P) molar ratios of 0.50, 1.00, 1.34, 1.50, and 1.67, respectively, was prepared for bulk specimen analysis using scanning electron microscopy (SEM) and energy-dispersive X-ray microanalysis (EDXA...

...AD Owens, M.S. Although the technique of scanning electron microscopy and energy-dispersive X-ray analysis (SEM/EDX) has gained widespread acceptance for the identification of gunshot residues (GSR), the time required (especially for manual searches) is still considered excessive. As a result...
