TL;DR: In this paper, three different sample preparation protocols were developed for the APT analysis of meteoritic nanodiamonds at sub-nm resolution and present carbon isotope peak ratios of both synthetic and meteoritic nano-diamonds.
Journal ArticleDOI
C12/C13-ratio determination in nanodiamonds by atom-probe tomography
TL;DR: The astrophysical origins of ∼ 3 nm-diameter meteoritic nanodiamonds can be inferred from the ratio of C12/C13, and sample preparation, atom-probe tomography analysis, 3D reconstruction, and bias correction are described.
Journal ArticleDOI
Correction of dead time effects in laser-induced desorption time-of-flight mass spectrometry: Applications in atom probe tomography
TL;DR: In this paper, a modified dead time correction procedure was proposed using data from correlated detection events from different isotopes of a single element, provided the signals are not affected by unresolved mass interferences.
Journal ArticleDOI
Combining Atom-Probe Tomography and Focused-Ion Beam Microscopy to Study Individual Presolar Meteoritic Nanodiamond Particles
Dieter Isheim,Frank J. Stadermann,J. B. Lewis,C. Floss,Tyrone L. Daulton,Andrew M. Davis,Philipp R. Heck,Michael J. Pellin,Michael R. Savina,David N. Seidman,Thomas Stephan +10 more
TL;DR: In this article, an extended abstract of a paper presented at Microscopy and Microanalysis 2013 in Indianapolis, Indiana, USA, August 4 -August 8, 2013 is presented.
Journal ArticleDOI
Origin of nanodiamonds from Allende constrained by statistical analysis of C isotopes from small clusters of acid residue by NanoSIMS
TL;DR: In this article, the authors implemented a technique using secondary ion mass spectrometry with maximized spatial resolution to measure carbon isotopes in the smallest clusters of nanodiamonds possible.
