Refractory metal nuggets within presolar graphite: First condensates from a circumstellar environment
TL;DR: In this paper, the authors show that the presolar refractory metal nugget (pRMN) compositions are variable (e.g., from 8 < Os atom% < 77), but follow the same chemical fractionation trends as isolated refractories metal nuggets (mRMNs) previously found in meteorites (Berg et al. 2009).
Structural clues to the origin of refractory metal alloys as condensates of the solar nebula
TL;DR: This article used focused ion beam (FIB) preparation to obtain electron-transparent sections of 15 submicrometer-sized refractory metal nuggets (RMNs) from the original Murchison residue.

Statistical mechanics of fullerene coalescence growth
TL;DR: In this article, a statistical analysis of fullerene sizes produced in a laser-induced microplasma finding that a simple two-parameter lognormal distribution describes impressively well the cluster frequencies under various conditions.

Nondestructive full-field imaging XANES-PEEM analysis of cosmic grains
P. Bernhard,J. Maul,T. Berg,Frederik Wegelin,Ulrich Ott,Ch. Sudek,H. Spiecker,S. Merchel,Gerd Schönhense +8 more
TL;DR: In this paper, a combination of X-ray absorption near-edge structure (XANES) and PEEM (photoemission electron microscopy) measurements on a cosmic grain fraction from the Murchison meteorite is presented.

Quantum confinement observed in the x-ray absorption spectrum of size distributed meteoritic nanodiamonds
T. Berg,E. Marosits,J. Maul,Peter Nagel,Ulrich Ott,F. Schertz,Stefan Schuppler,Christa Sudek,Gerd Schönhense +8 more
TL;DR: In this paper, a near edge x-ray absorption fine structure study of artificial chemical vapor deposition diamonds with sizes in the micron range and of size distributed nanodiamonds extracted from the Murchison meteorite is presented.
