Steven Hughes
ExpertiseChemistry, Semiconductor nanocrystal synthesis, CuInS2, AgGaS2
InstrumentationTEM, XRD, SEM (EDS), fluorescence (with integrating sphere), ICP
Background & Research InterestsThe focus of my continuing research is the synthesis and characterization of I-III-VI semiconductor nanocrystals. I am currently working with CuInS2 and AgGaS¬2 materials including various alloys and shelled compositions. My lab studies these materials to best understand their potential as LED phosphors and photocatalysts. Additionally, I’ve been working in collaboration with a developmental biologist to study the toxicity of these materials in zebrafish embryos. Collaboration Interests: 1.Better understanding the photophysics of our nanomaterials. Like CIS, AGS can have extremely intense trap state emission. Unlike CIS, this emission can be suppressed in order to observe the band gap emission. It’s neat, and I’d love to work with someone to understand this better. 2.Silver gallium sulfide has demonstrated the potential to be an effective photocatalyst for the reduction of hydrogen gas. I’m interested in working with someone who knows how to characterize materials for this application better than me.

Joe Keene
ExpertiseSemiconductor nanocrystals, quantum dots, isothermal titration calorimetry, surface chemistry, ultrafast spectroscopy
Instrumentation300 MHz NMR, UV-vis absorption and fluorescence, FT-IR, Raman, X-ray fluorescence, AAS, ICP-OES, isothermal titration calorimetry, GC-MS, UHPLC-MS, glove box, TEM
Background & Research InterestsMy current research projects focus on the thermodynamics of surface modifications on semiconductor nanocrystals. In particular, I am using calorimetry to investigate ligand exchange reactions on colloidal quantum dots to gain fundamental understanding of these reactions. I’m also working to adapt existing, alternative techniques to determine chemical composition of nanomaterials. I also work with the Mercer Engineering Research Center (MREC) on several projects addressing chemical- and surface-related challenges for the Department of Defense and the U.S. Air Force. These projects include: corrosion prevention and control; chemical, biological, radiological, and nuclear warfare agents; and composite repairs and bonding on multiple aircraft and service equipment and vehicles.
