Insights into secondary ion formation during dynamic SIMS analysis: Evidence from sputtering of laboratory synthesized uranium compounds with a high-energy O− primary beam on a NanoSIMS 50L

Autor: Tyler L. Spano, Roger J. Kapsimalis, Cole R. Hexel, N. Alex Zirakparvar, Andrew Miskowiec, Michael W. Ambrogio, Julie B. Smith

Publikováno v: Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms. 502:164-175

We investigate the sputtering and ionization process that takes place during secondary ion mass spectrometry (SIMS) analysis in order to develop a better understanding of the underlying controls on elemental and molecular oxide secondary ion yields.

Titanium isotopic compositions of well-characterized silicon carbide grains from Orgueil (CI): Implications for s-process nucleosynthesis

Autor: Julie B. Smith, Gary R. Huss

Publikováno v: Meteoritics & Planetary Science. 42:1055-1075

We have measured the titanium isotopic compositions of 23 silicon carbide grains from the Orgueil (CI) carbonaceous chondrites for which isotopic compositions of silicon, carbon, and nitrogen and aluminum-magnesium systematics had been measured previ

Presolar diamond, silicon carbide, and graphite in carbonaceous chondrites: implications for thermal processing in the solar nebula

Autor: Julie B. Smith, A. P. Meshik, Gary R. Huss, C. M. Hohenberg

Publikováno v: Geochimica et Cosmochimica Acta. 67:4823-4848

We have determined abundances of presolar diamond, silicon carbide, graphite, and Xe-P1 (Q-Xe) in eight carbonaceous chondrites by measuring the abundances of noble gas tracers in acid residues. The meteorites studied were Murchison (CM2), Murray (CM

Publikováno v: Imaging of Gynecological Disorders in Infants and Children ISBN: 9783540856016

Delayed and precocious puberty are distressing conditions that can have serious long-term effects, and may also be the presenting manifestation of serious underlying medical conditions affecting the hypothalamic-pituitary-gonadal axis. An understandi
