RESEARCH SUMMARY
Forensics is a rapidly expanding field that offers a variety of professional career options. A Bachelor of Science degree in forensic chemistry affords students the flexibility needed to launch an exciting and secure career in federal, state, or local labs associated with crime labs and medical examiner’s offices. Other job opportunities for forensic chemists lie in industrial and environmental positions or other fields of forensic science, academia, and administration. A professional forensic chemist is someone who runs tests on evidence found at a crime scene, which is essential for solving crimes. This evidence may include cloth fibers, hair, fingernails, paint chips, glass fragments, blood stains, or other bodily fluids. Characterization of evidence requires extensive knowledge in chemistry, biology, and genetics. As the director of forensic chemistry, I oversee the direction of the Forensic Chemistry Program. My administrative duties include revising the program’s curriculum as needed, recruiting and retaining the brightest young minds, developing students’ research skills through the use of high-tech analytical techniques from optical methods (ultra violet/visible, infrared, X-ray) and separation analyses (gas chromatography, HPLC, and thin-layer chromatography), and providing majors with academic and career advising. A master’s degree in forensic chemistry is being planned.

RESEARCH SUMMARY
The Delcamp laboratory is interested in the converting solar energy into more readily usable energy forms. We have two main focuses for accomplishing this goal: 1) generation of electrical energy and 2) generation of chemical energy.

In order to generate electrical energy from sunlight, we are further developing organic small molecules for the already promising dye-sensitized solar cell (DSC). We aim to broaden the strategies used in designing organic light harvesting materials for DSCs and organic photovoltaics. We are currently developing novel organic building blocks which will be amendable to a diverse array of organic electronic applications. Several of the polycyclic building blocks of interest are designed to balance competing local and larger annulenic aromaticities which should lead to unique light absorption characteristics from small molecules.

Additionally, we are interested in the generation of carbon based fuels from readily abundant CO2 with sunlight as the energy source. In order to photocatalytically convert a highly oxidized carbon source (CO2) into a more readily usable form, we aim to design catalytic systems capable of facilitating multiple synergistic chemical processes. Our focuses are on developing systems with no stoichiometric bi-products as is desirable for an energy projection technology and in further increasing the light absorption and catalytic activity of CO2 converting organometallic complexes.

RESEARCH INTERESTS
Spectroscopy and computational chemistry

RESEARCH SUMMARY
Spectroscopy and computational chemistry The overall goal of our research is the elucidation of chemical pathways by determining potential energy surfaces and characterizing reactive intermediates. We use both experiment and theory – matrix isolation spectroscopy and ab initio quantum chemistry. Currently we are focusing on the following areas, but students are encouraged to suggest other interesting projects.
1) Reaction of oxygen atoms with small organic molecules on the singlet and triplet electronic surfaces.
2) Hydrocarbon isomerizations and strain energies of small ring systems which incorporate trans double bonds on the reaction surface. A few specific examples are given below.

A technique suited for the isolation and characterization of reactive and unstable species is matrix isolation. Reactive intermediates such as free radicals and structures which have shallow minima on the reaction potential energy surface can be generated and trapped in an inert matrix (usually argon) at cyrogenic temperature (10 Kelvin) and examined by spectroscopic methods. Several methods such as thermolysis, photolysis, and plasma techniques are used to initiate the reactions and generate the species of interest. Condensation of the reaction mixture onto a 10 Kelvin substrate then “freezes” the reaction so that intermediates can be isolated; species can also be generated in the matrix itself through photolysis. The inert host matrix prevents further aggregation in addition to simulating a gas-phase environment while the low temperature quenches rotation and simplifies the vibrational spectrum, allowing for very sharp vibrational bands. For example, we were the first to report the production of butadienylketene from the reaction of benzene with oxygen atoms (J. Am. Chem. Soc. 1999, 121, 4721). The ketene product was stabilized by the matrix environment making its characterization possible (Scheme 1).

Another area of interest is the thermal isomerization of strained hydrocarbons. Tricyclo[3.1.0.02,6]hexane will thermolyze to give 1,3-cyclohexadiene. Arguments about whether the reaction could proceed through the (E,Z)-1,3-cyclohexadiene intermediate existed on both sides; through multiconfiguration self-consistent field calculations, we were able to show that the reaction indeed does go through the (E,Z)-1,3-cyclohexadiene intermediate (J. Phys. Chem. A 2003, 107, 198). Although the first step of the reaction can be described using a single-determinant wavefunction, the isomerization of the intermediate (E,Z)-1,3-cyclohexadiene via double bond rotation cannot. At the MP2 level the final product is erroneously bicyclo[2.2.0]hex-2-ene instead of 1,3-cyclohexadiene. Natural orbital occupation numbers verify the singlet biradical nature of the transition state, providing further proof of the necessity of a multiconfiguration treatment in the wavefunction. This is an example of MCSCF calculations adequately describing the entire PES, while single-determinant methods only describe part of it. The (E,Z)-1,3-cyclohexadiene intermediate is interesting in its own right. It exists in a very shallow well (3 kcal/mol) due to the high strain energy of incorporating a trans double bond in such a small ring. We are also studying the size limit for various rings with one or more trans double bonds and following their isomerization pathways using ab initio methods. The biradical nature of the transition state in the thermal isomerization of tricyclo[2.1.0.02,5]pentane to 1,3-cyclopentadiene is shown in Figure 1; two singly-occupied molecular orbitals are apparent. The prospective student will use a variety of ab initio methods on both linux clusters in our lab and mainframes maintained by the Mississippi Center for Supercomputing Research. Students interested in experimental physical chemistry will use the matrix isolation apparatus as well as learn to use computational chemistry techniques. These tools are extremely valuable as an aid in analyzing the vibrational spectra obtained experimentally.

RESEARCH SUMMARY
NSF CAREER award 2013-2018
Nanoscience is a new area of science that has generated excitement worldwide. Nanomaterials are being developed to address some of the world’s biggest challenges, including: clean, affordable energy; stronger, lighter, more durable materials; medical devices and drugs to detect and treat diseases; sensors to detect harmful chemical or biological agents; lighting that uses a fraction of the energy; low-cost filters to provide clean drinking water. We work on molecular gold nanoparticles (<2nm) that have precise number of gold atoms and ligands. Commercialization of nanomaterials and design of nanoengineered products will require: understanding of the fundamental properties; controlled synthetic and processing conditions. In my research group, we work on synthesis and characterization (mass spectrometry, NMR, optical spectroscopy) of these molecular gold nanoparticles.

RESEARCH INTERESTS
Analytical chemistry, environmental chemistry, forensic chemistry, biogeochemical cycling of mercury, environmental radioactivity, environmental monitoring and fingerprinting, analytical method development

RESEARCH SUMMARY
My research interests are in the area of analytical, environmental, and forensic chemistry. I am particularly interested in environmental monitoring and fingerprinting using isotope based methods. What counts in science is novelty. To that end, we enjoy developing new measurement techniques or applying standard techniques in novel ways. Listed below are some examples of the type of research that you may pursue if you were to join my group. I would welcome the opportunity to discuss these and other research possibilities with you as you decide whether to pursue graduate education in chemistry at Ole Miss.

Trace Elemental Analysis. I am interested in studying the behavior of trace elements (both stable and radioactive) in the environment. This sometimes involves developing novel analytical methods for measurement of the element or forms of the element (speciation). One of the methods we employ involves direct elemental and isotopic analyses of environmental or biological samples using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). This allows us to map the elemental distribution in, for example, tree rings, thin sections of brain tissue, glass shards, paint chips, fish otiliths, leaves, etc. Current research projects in this area include in-situ elemental analysis of leaves, herbal supplements, and biological shells, and the analysis of human hair and animal fur for metals. Future work may include environmental fate and transformation of nanoparticles, and evaluating metal redistribution in soils and biological uptake resulting from invertebrate burrowing, among others.

Mercury. Mercury (Hg) has probably the most complex biogeochemical cycle among the elements. Because of its tendency to bioconcentrate in food chains in the form of methyl-Hg and cause detrimental human health and ecological effects, it continues to be a hot button issue and a priority pollutant. Indeed, Hg is responsible for the most fish consumption advisories in the nation due to elevated Hg levels in fish flesh. This includes reservoirs in northern Mississippi nearby our campus. Current research projects in this area include the distribution and cycling of Hg in the Yocona River Watershed and development of a combustion-CVAFS system for Hg analyses. Future research projects may include, addressing spatial and dry deposition data gaps in Hg cycling chemistry models, evaluating Hg release characteristics from compact fluorescent lamps, environmental forensic investigations of Hg using high precision isotope measurements, and using mosquitoes as bio-indicators methyl-Hg accumulation in food webs, among others.

From the above examples and the select publications listed below you can get a sense of the type of research my group conducts. The studies often include a combination of method development and field experiments that serve to provide much needed quality data to address current hype on an issue or to increase understanding of natural phenomena. My experience and expertise in environmental and analytical chemistry offers opportunities for students to apply chemical principles to understand environmental problems, the first crucial step in solving them.

Instrumentation. Our research laboratory is well-equipped for trace elemental and isotopic analysis. It includes a high resolution ICP-MS (Element-XR), a quadrupole-ICP-MS (X-Series 2), a laser ablation system (UP-213 New Wave), an ICP-OES (Perkin Elmer Optima 2100), a microwave digestion system (Milestone Ethos EZ), a cold vapor atomic fluorescence spectrometer (Tekran 2600), a direct mercury analyzer (DMA-80 Milestone), an automated MeHg analysis system, airborne mercury speciation equipment, and clean-room facilities. We also have access to a variety of other instruments commonly found in Chemistry Departments such as GC/MS, NMR, XRF, FT-IR, and IRMS.

ICP-MS Facility. We are fortunate to have a new state-of-the-art ICP-MS facility housed in the Department of Chemistry and Biochemistry. ICP-MS is a sensitive multi-element technique which provides a powerful analytical tool for trace elemental and isotope analysis. It is used in a wide-variety of environmental, biological, medical, forensic, geological and archaelogical studies.

RESEARCH INTERESTS
Preparation of models for the metal centers of metalloenzymes and proteins, including the nickel-containing hydrogenases and urease; synthesis of novel metal sulfur clusters; preparation of self-assembled monolayers on gold having unusual electronic, optical, or magnetic properties

RESEARCH SUMMARY
The research interests of our group are in the areas of synthetic inorganic and bioinorganic chemistry. More specifically, we are interested in the preparation and properties of metal sulfur complexes as models for a variety of important biological systems and industrial processes. Enzymes such as the nickel-containing hydrogenases, carbon monoxide dehydrogenase, and urease possess nickel-containing active sites for which no accurate structural, electronic, and chemical model complexes have been prepared. The main focus of our bioinorganic research involves the emerging role of nickel in biological systems. Nickel has recently been shown to be an essential component in several enzymes, including jack bean urease; several hydrogenases; carbon monoxide dehydrogenase; and S-methyl coenzyme-M methyl reductase, the terminal enzyme in methane-producing bacteria. Although the involvement of nickel is now well-established, relatively little is known about the details of the structure and function of the nickel sites in these enzymes.
