Aurora E. Clark
In the Clark lab we use computational chemistry (simulating chemistry on a computer) to answer questions that are difficult, and sometimes impossible, for experimentalists to do:
- Help design high density multi-layered information storage devices. Here we perform calculations that determine the optical properties of molecules that are good candidates for media in high-density information storage devices (imagine a DVD that can hold more than a terabyte of data!)
- Understand how molecules fall apart. Perform calculations on the decomposition of a wide variety of molecules that are important in our every day lives (e.g., molecules used in electronics)
- Model environmental chemistry. Perform calculations on heavy element complexes and model how they travel through environmentally relevant media (water, soil).
The Garner lab provides research opportunities for motivated undergraduates in the area of organic chemistry. Typically, the undergraduate research experience begins with basic training in organic synthesis under the guidance of a graduate student followed by an independent research project. Students are encouraged to begin doing research upon completion of CHEM 427 (or its equivalent). Please contact Dr. Garner (firstname.lastname@example.org) for more information.
Zachariah M. Heiden
Research in the Heiden lab focuses on using experimental and computational techniques to understand and develop new chemical reactions to solve energy and environmental related problems. Current research projects include:
- Investigation of the thermodynamics of hydrogen and hydride transfer for the development of new catalysts with increased selectivities and activities.
- To create or break chemical bonds using light to turn on/off catalysis for the promotion of new chemical reactions under mild conditions.
- Employ metal complexes capable of reversibly storing hydrogen for the promotion of unprecedented chemical reactions and transformations.
- Synthesis and purification of metallorganics. These materials are similar in structure to Vitamin B and hemoglobin. Our end interest is in using these as components in single molecular electronic devices.
- Take pictures of molecules! The idea of supramolecular synthons, now well established for crystal design, is being developed in the two dimensional (surface) world by my research group. This research encompasses the design, creation, and analysis of self-ordering 2-D structures.
- Ultra-high vacuum (UHV) studies of molecular films. In this project the student will work with films of the order of one molecule thick under UHV (<10 -12 atmospheres!). The student will learn a number of basic techniques that are in high demand in the rapidly growing Nanotechnology Industry
Alexander DeQuan Li
Research in Dr. Li’s lab is focused on conjugation of biomolecules with synthetic molecules for studying nano-bio-materials and innovative approaches to unusual structures and properties. Undergraduates can become involved in the study of molecular design, organic and inorganic chemistry, biochemistry, and polymer science. Projects range from preparation of nanoporous polymers and hollow nanospheres to the synthesis and self-organization phenomena of smart oligomers or polymers.
Several PCPs, such as 2,4,5- and 2,4,6-trichlorophenol (TCP), are primarily introduced into the environment through their use as preservatives in the wood industry, as herbicides in agriculture, and as general biocides in consumer products. They persist in the environment because chloride substitution makes them recalcitrant to microbial degradation. The high levels of EDTA in natural waters are also due to its extensive usage, such as in industrial cleaning, in detergent and in phytoremediation to mobilize heavy metals. In the environment, EDTA occurs in metal-EDTA complexes, most of which are highly recalcitrant. Recently, several enzymes from soil microorganisms have been characterized, which degrade 2,4,5-TCP, 2,4,6-TCP and EDTA. Our on-going research is essential for improving the catalytic efficiency and substrate range of critical enzymes involved in biodegradation of recalcitrant pollutants, targeting effective bioremediation.(http://kang7.chem.wsu.edu/~kang)
Our research focus on controlled self-assembly of molecules via selective noncovalent intermolecular interactions (van der Waals, hydrogen bonding, dipole–dipole interactions) which offers a powerful approach for the development of multidimensional nanostructures which possess functions such as rectifying, switching, and sensing. We employ phthalocyanine and porphyrin molecular photoconductors for constructing stable electrostatically bound 2D and 3D assemblies/aggregates which are of interest for their potential applications in optoelectronic devices and in solar energy conversion. We perform fundamental studies focusing on the understanding of the link between aggregate morphology, molecular structure, and their optical and electronic properties thus allowing these properties to be tuned for a particular application, borrowing ideas from nature where light harvesting aggregates (LHA) are optimized to collect and funnel solar energy to a reaction center. The techniques that we use in our studies include optical and electronic spectroscopy: Raman, UV-vis, XPS, and scanning probe microscopy: AFM and STM. We hope that our contributions for improving the understanding of phthalocyanine and porphyrin self-organization will help to pave the way for constructing functional composite devices for light to energy conversion.
Research in Dr. Reilly’s lab focuses on the development of mass spectrometers to perform novel measurements. In particular, our focus is on the extension of the working range of mass spectrometers from 2×104 to 1×109 atomic mass units and beyond so that singly-charged ions can be mass analyzed with high resolution and mass accuracy. The idea is to directly mass analyze intact proteins, protein complexes, RNA, DNA and even whole viruses and quantify their distributions. Undergraduates can become involved in the development of the spectrometers or the applications. Projects range from analytical methods development to investigation of the fundamentals of mass spectrometry.

- Study of geometrical and electronic properties of single and multilayer molecular films deposited by Langmuir-Blodgett method on Si substrate. The films will be characterized by AFM and/or STM.
- Synthesis of core/shell structures (Pd/Cu) for improved fuel cell efficiency. These core/shell structures will be imaged by TEM and tested by cyclic voltammetry (CV) and chrono-amperometry (CA) in collaboration with the chemical engineering department.
The core of Dr. Xian’s research interests comprises the desire to combine organic synthesis with bioorganic chemistry to examine, understand, and solve problems of biological and medicinal significance. We are interested in the areas of (1) synthetic methodology development and natural product synthesis; (2) protein molecular recognition and interaction; and (3) the development of new therapeutic agents. Undergraduate students involved in these projects will learn basic organic synthesis skills and the use of modern analytical instrumentation. Moreover students will also be trained to write lab reports and papers, prepare posters, present seminars, and encouraged to take part in scientific conferences. The mastering of the knowledge and the techniques will make students more competitive in their future careers.
Dr. Yoo’s group focuses on extreme materials research at the pressure-temperature conditions of the Earth’s and Joviant planetary interiors, where materials alter their properties in many fundamental ways and, thus, provide exciting opportunities for us to discover new materials, novel phenomena, and exotic states of matter- not present at the ambient condition. Examples include stishovite-like carbon dioxide polymer, metallic hydrogen, superconducting lithium, superionic water, novel metal nitrides, highly correlated f- and d-transition metals and their alloys and compounds, and many more. High-pressure research will ultimately establish a new Periodic Table of the elements with completely redefined chemical and physical properties.
Modern static and dynamic high-pressure technologies coupled with state-of-the-art laser spectroscopy are utilized together with x-ray diffraction and x-ray spectroscopy at national synchrotron facilities. Materials of research interest range from fundamental materials of quantum solids, molecular solids, covalent and ionic solids, and f-and d-electron metals to functional materials such as reactive nanoparticles, hydrogen storage materials, strongly correlated systems, and high energy density solids.
