Dye Synthesis, Photochemistry, Photographic Science, Patents, and Research Disclosures

The author’s wide background in science will be a great asset in helping you with your crystallization needs. His expertise is shown by many publications, in peer-reviewed journals. These give testimony to knowledge in physical chemistry, photochemistry, spectroscopy, photographic science, chemical synthesis, and other areas. This knowledge in chemical and physical sciences is applied when consulting on crystallization processes.

The author’s Patents and Research Disclosures taught how to design experiments with patent possibilities, and to help detecting patentable experimental results.

These publications, patents, and research disclosures  are the result of research at the Technical University of Munich ( Germany), at Texas Christian University (Fort Worth, TX), from the research laboratories of Eastman Kodak Company (Rochester, NY), and Crystallization Consulting.
