Hello All!

Here are some references concerning nanodiamonds:

chondrites: (I) Theory (Meteoritics 28-3, 1993, A416).

chondrites: (2) Experiment (Meteoritics 28-3, 1993, A405).

nanodiamonds from the Orgueil meteorite (Meteoritics 32-5, 1997, 713).

circumstellar environments? (Meteoritics 32-4, 1997, A060).

Best wishes,


P.S.: Dieter Heinlein just phoned me because he wanted to know if
I had recorded last night's special topic (Asteroids) on VOX TV. No,
sorry, folks, I didn't. So I can't provide any copies :-(
