Meteoritics &Planetary Science, Volume 60, Issue 3, Page 529-543, March 2025.Abstract Solar wind Fe and Mg fluences (atoms/cm2) were measured from Genesis collectors. Fe and Mg have similar first ionization potentials and solar wind Fe/Mg should equal the solar ratio. Solar wind Fe/Mg is a more valid measure of solar composition than CI chondrites and can be measured more accurately than spectroscopic photospheric abundances ...

VIS‐to‐MIR reflectance and Raman spectroscopy of the CM2 NWA 12184 carbonaceous chondrite
Meteoritics &Planetary Science, Volume 60, Issue 3, Page 570-595, March 2025.Abstract The spectral analysis of CM meteorites can help to constrain the mineralogical composition of their parent body, the C‐type asteroids. The CM2 NWA 12184 was spectrally examined employing seven complementary techniques at different spatial resolutions, including VIS‐to‐MIR reflectance and Raman spectroscopy.

Silicate–sulfide interaction within quenched melts of space weathered Ryugu grains
Meteoritics &Planetary Science, EarlyView.Abstract The first few microns of the surface of airless bodies are subject to severe changes due to the harsh environment of space, known as space weathering. The Hayabusa2 sample return mission from the asteroid Ryugu provides the first opportunity to study these effects on a carbonaceous and hydrated body.

Computer-Aided Civil and Infrastructure Engineering, EarlyView.Abstract Grain morphology is a fundamental characteristic of lunar soil that influences its mechanical properties, sintering behavior, and in situ resource utilization. However, traditional two‐dimensional imaging methods are time‐consuming and lack full three‐dimensional (3D) structural information. This study presents an automated deep learning‐based

R&D Management, EarlyView.ABSTRACT This study examines the impact of knowledge spillovers on product innovation performance within UK medium to high‐tech start‐ups. We propose a conceptual model that explains the relationship between incoming and network knowledge spillovers, potential and realized absorptive capacity, and exploratory and exploitative innovation performance ...
