Dr. Russell Franks - Assistant ProfessorEducational Background: SFASU, 1994, B.S. Chemistry, 1996, M.S. Chemistry; University of Oklahoma, 2002, Ph.D. ChemistryResearch/Areas of Interest: Organic chemistry, Alternative fuels, organometallic chemistry, chemical educationOffice: Math Building, Room 114Phone: 936.468.2199E-mail:rjfranks@sfasu.edu

Dr. Franks' research interests are in the study of the chemical and physical properties of biodiesel fuels made from a wide variety of plant- and animal-derived triglyceride sources. His group is presently studying the use of microwave heating methods to facilitate biodiesel synthesis, the synthesis of biodiesels made from less-commonly used alcohol sources, and the synthesis and characterization of biodiesels made from plant-derived feedstocks that are not used for food by humans. Biodiesel samples are characterized using IR spectroscopy, NMR spectroscopy, GC/MS, viscometry, and bomb calorimetry.

I was born and raised in San Antonio, TX. My dissertation research was in organometallic catalysis. I taught for two years at OU, and have been at SFA since July of 2005. I teach General Chemistry and Organic Chemistry here at SFA. In my free time, I enjoy music, cooking, reading, family activities, and following OU Football.

Dr. Alyx Frantzen - Associate ProfessorEducational Background: Texas Lutheran University, 1991, B.S. Mathematics, Chemistry; New Mexico State University, 1996, M.S. Chemistry, Mathematics; New Mexico State University, 1998, Ph.D. Physical ChemistryResearch/Areas of Interest: Physical ChemistryOffice: Math Building, Room 119Phone: 936.468.2338E-mail:afrantzen@sfasu.eduDr. Frantzen's research involves phylloaluminosilicates. These materials are commonly used as ubiquitous adsorbents, but can also be tailored for use as highly selective adsorbents. The clays have been modified using amino acids and have been successfully used to separate racemic mixtures. Clays are also being exchanged with metalloporphyrins to examine the changes in the absorption/emission spectra of the macro cycle. While most of Dr. Frantzen's research involves clays, research is also being done on the effects of Yaupon, Chinese Tallow, and Chinese privet on surface fuel volatility in the East Texas Region. These all represent invasive plant species that have been introduced into East Texas. The work being done with these species will investigate total volatility of these surface fuels in fire models. The volatile components of each invasive species will be evaluated using oxygen bomb calorimetry, thermal gravimetric measurements, and gas chromatography/mass spectrometry.

In his Ph.D., Dr. Fry worked extensively with fluorescent probe molecules in hydrophobic environments. He has extended this interest to understanding the interaction between the chemical microenvironment and the probe molecule. Currently, Dr. Fry is working with fluorescein and porphyrins. For fluorescein, his goal is to understand fluorescein in different solvent systems. With this understanding, some of the limitations of fluorescein as a probe molecule can be overcome. His goals with the porphyrins are to develop a solid-state fluorescence sensor for various metals in solution. As a college professor and high school teacher, Dr. Fry has learned the importance of exciting students about learning chemistry. Currently he is working with college students in developing a series of chemical demonstrations for younger students. Moreover, he is also working at developing new laboratories for college students.

Areas of Research Interests

Environmental Analytical Chemistry; Environmental Health; Water Resources Research; Development of Analytical Methods with Atomic Spectroscopy and Chromatography; Science Education.

Research Programs

Water Resources Research: There are three research themes that focus on water resources: (1) investigation of microbial mediation in phosphate removal by wetlands, (2) chemical characterization of biosolids and their impact on ground water quality, and (3) studies of emerging contaminants. These research efforts are supported by an analytical facility that consists of state-of-the-art analytical instrumentation for the determination of nutrients (phosphates and nitrates), heavy metals, organic pollutants, pharmaceuticals and personal care product contaminants.

Study of Environmental Processes at the Molecular Level: This research is focused on studying the interaction of chemical species with solid surfaces and the mitigating effects of these interactions on environmental contamination. It looks at environmental processes at the molecular level, seeking to elucidate how the natural environment is affected by contaminants, and how the affected environment can be restored. The materials under investigation include soils and sediments; bio-materials such as plants and bio-solids; natural organic matter; synthetic chelating agents; and naturally occurring polymers.

Heavy Metal Speciation Studies: This work is aimed at investigating the forms in which heavy metals exist in environmental systems and the factors that influence their distribution. The study has led to the development of new analytical methods which have been applied in the elucidation of the toxicity and other biological effects of heavy metals.

Distribution and Fate of Hazardous Substances in Environmental Systems: This research is aimed at studying the chemistry of pesticides, heavy metals, and other toxic substances in environmental systems. By knowing how these materials behave under various conditions, analytical methods for identifying and quantifying them can be developed.
