Recent News from the Gladden Group




  • October 2009:
    • The big Physics Dept. Halloween Extravaganza will be held on Friday 10/30 from 7:00 - 10:00!  There will be hands on demos, liquid nitrogen icecream, and I'll be running a series of demo shows in the big lecture hall.  Don't miss it!
    • I presented a paper to Project Listen Up at the Acoustical Society of America meeting.  The paper outlined the construction of a simple and inexpensive apparatus for demonstrating 2D resonances in a circular elastic membrane.
      I have put together a web page with related materials. 
    • I gave a colloquium at Indiana University on wormlike miceller fluids.
    • We began a new project on the development of super rugged and flexible acoustic sensors. This project is funded by ARDEC, part of the DOD.
  • July 2009:
    A paper we have recently published in the Journal of the Acoustical Society of America (JASA) [PDF] has been selected for republication in the Virtual Journal of Nanoscience and Technology (Virt. J. Nan. Sci. & Tech. 20 (4), July 2009). This paper reports speed of sound and acoustic attenuation in multiwall carbon nanotube and nylon polymer composites.
  • January 2009:
    I will be in Santiago, Chile at the International Congress on Ultrasonics to give a talk on our high temperature RUS work. A copy of my slides can be downloaded here [ PDF ].

    My graduate student Guanyan Li successfully defended his Ph.D. perspectus! Congratulations to him!

    We are beginning a new project to study elastic moduli of palladium hydrides under high pressure and temperature near the triple point in the Pd-H phase diagram. This is a collaboration with Los Alamos National Lab.
  • November 2008:
    I will be giving the "Hot Topics in Physical Acoustics" address at the ASA meeting in Miami (Nov. 10-14, 2008). Here is a popular version of the section on "Cosmic Sound Waves" [published by AIP].
    I have also posted my slides from the Hot Topics talk. [ PDF ]

    My graduate student, Guanyan Li, will be defending his Ph.D. perspectus this month.
