Research Interests:
Research in my group tends to be multidisciplinary and there are strong aspects of physics, analytical, physical, organic and inorganic chemistry in our projects, but the primary focus revolves around the unifying themes of photonics, lasers, instrumentation and spectroscopy.

We have recently made fundamental breakthroughs in solubilizing carbon nanotubes and have developed solvent systems that will truely dissolve single wall nanotubes and graphene and create thermodynamically stable solutions. This discovery contradicts the general assumption that no solvent would dissolve nanotubes and graphite. As part of our ongoing collaboration with Trinity College Dublin-Physics and the group of Professor Johnny Coleman, we published a fundamental paper in Advanced Materials in which we definitively proved that the Gibbs Free Energy of Solution was Negative for single wall nanotubes (SWNTs) in NMP solvent, contrary to conventional chemical history and wisdom (here's the abstract). This work was featured in Science as an Editors Choice, "Can nanotubes swim apart?" and in Chemical and Engineering News in Science and Technology Concentrates. We continue to make great strides in nano solubility using graphene, multiwall nanotubes and nanocellulose. For the nanocellulose, we have just started a collaboration with the US Forest Products Laboratory. Numerous patents through WiSys/WARF are pending resulting from this work.

We also are particularly interested in the analysis of optical surface cleanliness to support our work in developing polymer stripcoatings for optics and Contamination Control for spacecraft with NASA. Our efforts in this area include exciting collaborations and visits to the worlds largest telescopes atop Mauna Kea Hawaii, the European Southern Observatory (ESO) in Munich and Chile, at the Advanced Photon Source at Argonne National Lab and the Smithsonian Institution in Washington, DC. Recently nanosecond laser damage studies clearly showed that our polymer coatings leave no residue upon removal and are high power laser safe. Laser Damage Testing(LDT) continues. Also using our Contiuum nanosecond optical parametric oscillator OPO system, the Perkin Elmer Lambda 900 UV/VIS/NIR and Princeton Instruments photon counting ICCD spectroscopic camera, we are studying the correlations in the chemical and physical origins of diamond luminescence with lots of samples from the national mineral collection at the Smithsonian. Surface cleanliness is of fundamental importance in many areas and our group works with NSF's Gravity Wave Observatory, LIGO (The Laser interfereomtric Gravity Observatory) based at Caltech and MIT, and with two Dark Matter search collaborations, COUPP (The Chicagoland Observatory for Underground Particle Physics) at the University of Chicago and Fermilab and CDMS (The Cryogenic Dark Matter Search) located in the Soudan Mine in Minnesota. Also, working with Fermilab scientists and engineers, we have just published a paper using our polymer technology on the CMOS CCD sensors of the Dark Energy Survey Camera where we used nanotube doped, ESD free films to clean and protect the delicate camera sensors.
We also work closely with colleagues within the department and university and have built photon counting, laser induced fluorescence systems for capillary electrophoresis with Professor Steiner, DNA Electrophoresis imaging systems with Professor Mendis , graphene functionalization and Chromone Laser Dye Synthesis with Professor Li. We have been working on a novel method of fingerprint development from unusual surfaces with the Madison, Wisconsin Crime Lab, the US Secret Service in Washington and Aric Dutelle in Criminal Justice. We are part of an international collaboration with Electrical Engineering at the Dublin Institute of Technology and the University of Applied Sciences in Darmstadt, Germany we are on our 3rd masters student (and now our first PhD) and have been working on novel, inexpensive and practical Alkaline Fuel Cell technology.
