RESEARCH INTERESTS: Radionuclide applications, including the study of cosmogenic nuclides and accelerator based Surface Layer Activation for studying wear in mechanical systems. Currently investigating evidence of supernovae or gamma ray bursts in excursions in cosmogenic nuclide production to see whether such events might have been responsible for global extinctions. Also applying SLA to wear in biomedical implants. If you would like to know more about the cosmogenic nuclide collaboration with the University of Kansas, please click here.  If you would like to know more about the technique of Surface Layer Activation, click  here.   


             

Dr. Ken Duffy, collecting soil samples for            Representative fossils collected from Tunica in 2004, added to
cosmogenic nuclide measurements from late        the Audubon collection now at Louisiana State University.
pleistocene loess deposits along Tunica
Bayou north of St. Francisville, Louisiana.

 Mastodon tusk removed from Big Thompson Creek, just east of Tunica Creek, by LSU Geology team led by Dr. Judy Shiebout in 2005.

In previous research, I have applied automated gamma ray spectrometry configurations to gamma backscattering for nondestructive inspection of welds, composite materials, and even Space Shuttle tiles (funded by NASA).  If you would like to know more about this approach, please click here.

 

Past work also includes applications of ion beam microtextured metals to thermophotovoltaic (TPV) power sources, to ultracapacitor electrodes (funded by NSF), and for controlling optical properties. This work also relates to nanotechnology and surface chemistry. Most of it has been performed in collaboration with the Ion Optics Corporation of Waltham, Massachusetts, a company specializing in ion beam modifications of metal surfaces to control infrared absorption and emission. For more                                                                  information about our TPV testing, please click  here.

 

I also am continuing to follow recent work on deep inelastic electron scattering in heavy nuclides, particularly single nucleon knockout to 700 MeV, particle track etching in dielectrics, particle interactions and radiation corrections. Some of this work may have implications for cosmology and astrophysics.
