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.
