TL;DR: In this paper, it was shown that all differentiated planetary bodies have isotopically heavier magnesium compositions than chondritic meteorites, and that the magnesium isotope fractionation during condensation of the solar nebula, core formation and silicate differentiation cannot explain these observations.
Laboratory Experiments Bearing on the Origin and Evolution of Olivine-rich Chondrules - eScholarship
TL;DR: In this paper, the evaporation kinetics of a chondrule-like melt and the potassium isotopic fractionation were investigated under various conditions ranging from high vacuum to pressures of one bar of H2+CO2, or H2 or helium.

Diffusive fractionation of K isotopes in molten basalts
TL;DR: In this paper , the authors measured the 41K/39K isotope ratio profiles in diffusion couple experiments using secondary ion mass spectrometry (SIMS) and showed that the precision of a single day-night session of SIMS measurements can reach 0.2

Piers Koefoed,Olga Pravdivtseva,Ryan C. Ogliore,Yun Jiang,Katharina Lodders,Mason Neuman,Kun Wang +6 more
TL;DR: In this article , the formation mechanisms of CB chondrites were investigated by analysing the elemental and K isotope compositions of chondrules and bulk fractions from the CBa chondrite Gujba.

Cr stable isotope fractionation by evaporation from silicate melts
TL;DR: In this paper , the authors present new experimental results of Cr isotope fractionation during degassing of silicate melts, showing that evaporative loss of Cr is substantial and depends on run duration and on temperature.

Solar System Abundances and Condensation Temperatures of the Elements
TL;DR: In this article, solar photospheric and meteoritic CI chondrite abundance determinations for all elements are summarized and the best currently available photosphere abundances are selected, including the meteoritic and solar abundances of a few elements (e.g., noble gases, beryllium, boron, phosphorous, sulfur).

TL;DR: This work presents a novel and scalable approach to genome-based approaches that combines cell reprograming, nanofiltration, and ‘spatially aggregating’ techniques that allow for real-time assessment of the impact of environmental factors on gene expression and disease progression.

Chemistry of glasses
TL;DR: In this paper, the authors present an approach to the formation of a glass, including two phases of transformation in glass, and the theory of chemical bonding in transition metal complexes, as well as acid-base relations in glass.

Applying Stable Isotope Fractionation Theory to New Systems
TL;DR: Theoretical estimates of isotope fractionations are particularly powerful in systems that are difficult to characterize experimentally, or when empirical force field calculations and ab initio quantum chemistry are needed as discussed by the authors.
