NanoSIMS-Analyse und hochauflösende Elektronenmikroskopie an präsolaren Silikaten aus roten Riesensternen und Supernovaexplosionen [PDF]

, 2009
This thesis deals with the analysis of “presolar” silicates and oxides by high resolution mass spectrometry and electron microscopy techniques. This “stardust” was identified by its extreme oxygen isotopic anomalies, which point to nucleosynthetic ...

Correlative chemical and elemental nano-imaging of morphology and disorder at the nacre-prismatic region interface in Pinctada margaritifera

Scientific Reports, 2023
Understanding biomineralization relies on imaging chemically heterogeneous organic–inorganic interfaces across a hierarchy of spatial scales. Further, organic minority phases are often responsible for emergent inorganic structures from the atomic ...

When biology meets materials science – Interdisciplinary applications of electron microscopy

Journal of Microscopy, EarlyView.
Abstract Research at the interface between biology and materials science creates challenges for electron microscopists. Everything from the sample preparation to the choice of imaging and analytical techniques and the interpretation of the resulting data refuses to sit comfortably within the domain of one discipline or the other.

(INVITED)Study of dopant distribution in Cr4+:YAG transparent ceramics and its use as passively Q-switching media in Nd:YAG laser delivering 38 mJ per pulse

Optical Materials: X, 2021
In this work, the role of elaboration parameters (i.e. chemical composition and heat treatments) of Cr:YAG ceramics on their microstructural, optical and laser properties was investigated.

Visible, near‐, and thermal infrared spectra of asteroid Bennu samples: Relationship to and implications for remote sensing of carbonaceous asteroids

Meteoritics &Planetary Science, EarlyView.
Abstract Remote spectroscopy is used to characterize the mineralogy and infer the history of planetary bodies. Carbonaceous asteroids, such as B‐type (101955) Bennu, represent the earliest stages of planet formation. B types have a blue (negative) spectral slope and comprise <5% of asteroids.

NanoSIMS Reveals New Structural and Elemental Signatures of Early Life [PDF]

, 2006
The young technology of NanoSIMS is unlocking new information from organic matter in ancient sediments. We have used this technique to characterize sub-micron scale element composition of Proterozoic organics that are clearly biogenic as a guide for ...

Oxygen isotope variability in the IIIAB iron meteorites and their relationship to main group pallasites

Meteoritics &Planetary Science, EarlyView.
Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses

Nutritional quality traits in pea seed: Current knowledge and opportunities for genetic improvement

Annals of Applied Biology, Volume 189, Issue 2, September 2026.
This comprehensive review on nutritional traits in pea (Pisum sativum L.) summarizes the literature on genetic improvement of this highly nutritious and environmentally sustainable crop for different end‐uses. Abstract Pea is a major pulse crop valued for its high protein, carbohydrate, and mineral content, as well as its agronomic role in sustainable ...
