Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Observing classical nucleation theory at work by monitoring phase transitions with molecular precision. [PDF]

open access: yes, 2014
It is widely accepted that many phase transitions do not follow nucleation pathways as envisaged by the classical nucleation theory. Many substances can traverse intermediate states before arriving at the stable phase. The apparent ubiquity of multi-step

Vertical profiling of shock attenuation at the Rochechouart impact structure, France

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Rochechouart, south‐west France, is a complex impact structure. Here, we present the first report of shock barometry of quartz from what are likely parautochthonous basement units at depth, based on samples from the 2017 C.I.R.I.R drilling campaign. The crystallographic orientations of 725 sets of PDFs in 512 quartz grains in samples from four

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Localized moving breathers in a 2-D hexagonal lattice

open access: yes, 1997
We show for the first time that highly localized in-plane breathers can propagate in specific directions with minimal lateral spreading in a model 2-D hexagonal non-linear lattice.

The (trans)national Russian religious imagination in exile: Iulia de Beausobre (1893‐1977)

open access: yesModern Theology, EarlyView.
Abstract The article offers a case study of how Russian Orthodox who migrated from the Soviet Union after the Bolshevik Revolution of 1917 reimagined their religious identity and their church in a transnational setting. Iulia de Beausobre (1893‐1977) was a Russian aristocrat who fell victim to the Stalinist purges but survived the Soviet prison system ...
