Fun in the Sand: Some Experiments in Granular Physics
25 Oct 2010 | | Contributor(s):: Peter E. Schiffer
In the last two decades, condensed matter physicists have begun an intense study of the dynamic and static properties of granular media (materials made from individual acroscopic solid grains). These materials offer a vast arena of new physical phenomena which are highly accessible and largely...
Aluminum: a safe, economical, high energy density material for energy storage, transport and splitting water to make hydrogen on demand
30 Mar 2009 | | Contributor(s):: Jerry M. Woodall
In 1968, a team lead by the author discovered that liquid gallium saturated with aluminum at room temperature would split water into hydrogen gas, alumina and heat. More recently his current team has discovered that bulk, solid Al rich alloys will also split water in the same manner. Since 1)...
C.V. Raman and the Impact of Raman Effect in Quantum Physics, Condensed Matter, and Materials Science
out of 5 stars
18 Sep 2008 | | Contributor(s):: Anant K. Ramdas
Raman’s momentous discovery in 1928 that the spectral analysis of the light scattered by matter, illuminated with monochromatic light of frequency ωL, reveals new signatures at (ωL ± ωi) , ωi’s being the internal frequencies of the matter [Nature121, 501 (1928); Indian Journal of Physics 2, 387...
Computing the Horribleness of Soft Condensed Matter
19 Oct 2007 | | Contributor(s):: Eric Jakobsson
A great triumph of computer simulations 40 years ago was to make the liquid state of matter understandable in terms of physical interactions between individual molecules. Prior to the first simulations of liquid argon and liquid water in the 1960's, there was no quantitatively rigorous molecular...
