s.u. for definition in English Explanation: Christian Sinn IAP, University of Bern, Sidlerstr. 5, CH-3012 Bern Aerogel precursos are liquid-filled gels which are produced by hydrolysis of tetraalkyl siloxane. Upon supercritical removal of the liquid, the silica network remains intact and forms a highly porous solid body - the aerogel. We are interested in the liquid-filled precursors as hosts for tracer particle diffusion in porous materials. A bit unexpectedly, we observed strong ringing-gel behaviour of our samples, that is the jelly-like materials emit a characteristic sound upon knocking at the container. We determine the frequency-dependent response of the gels and discuss the results in terms of Biot's theory for sound propagation in porous media. -------------------------------------------------- Note added at 40 mins (2005-04-07 15:21:23 GMT) -------------------------------------------------- I doubt a suitable German term exists. I would leave \"Ringing-Gel\" and put a few of its most important characteristics behind it in brackets - wet look, thick, non-greasy - the things you find when you look up \"ringing gel\" on google.

Brummgel Explanation: http://www.google.de/search?hl=de&q=ringing gel&meta=lr=lang... Kubische und hexagonale Flüssigkristalle zeigen ein deutliches visko-elastisches Verhalten, also sowohl die rheologischen Eigenschaften eines Festkörpers wie auch die einer Flüssigkeit. Wie typisch für die meisten Gele, haben sie eine ausgeprägte Fließgrenze. Kubische Tensidgele reagieren beim Einwirken mechanischer Kräfte außerordentlich elastisch. Da die Eigenfrequenz der Schwingung nach einem Stoß im hörbaren Bereich liegt, werden sie auch als Brummgele („ringing gels“) bezeichnet. |
