Unraveling the Proton‐Induced Degradation Mechanism in Quantum‐Dots Light‐Emitting Diode for Space Applications

open access: yesSmall, EarlyView.
Low‐energy proton irradiation induces ligand detachment at the QD/ZnO interface in quantum‐dot light‐emitting diodes (QLEDs). The exposed ZnS surface interacts with ZnO defects, generating a high density of interfacial trap states that promote electron trapping, suppress charge injection, and accelerate non‐radiative recombination, ultimately leading ...

DOSIS & DOSIS 3D: radiation measurements with the DOSTEL instruments onboard the Columbus Laboratory of the ISS in the years 2009–2016

open access: yesJournal of Space Weather and Space Climate, 2017
The natural radiation environment in Low Earth Orbit (LEO) differs significantly in composition and energy from that found on Earth. The space radiation field consists of high energetic protons and heavier ions from Galactic Cosmic Radiation (GCR), as ...

Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

open access: yesInsect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Distribution of Seed Electron Phase Space Density Minima in Earth's Radiation Belts

open access: yesGeophysical Research Letters
We conducted a statistical analysis of local phase space density (PSD) minima across a wide energy range (∼20 keVs to ∼10 MeV), using observations from the Van Allen Probes and the Geostationary Operational Environmental Satellite.

Microplate Tectonics Through Earth History and Across Solid Multispheres

open access: yesGeological Society of China Bulletin, EarlyView.
The evolution of tectonic microplates throughout Earth´s history as well as the transitions between microplates across different solid spheres offers a novel approach to expanding the traditional plate tectonics theory. ABSTRACT The evolution of tectonic microplates throughout Earth's history as well as the transitions between microplates across ...

Solar and geomagnetic activity modulation of wave–particle interactions in Earth’s radiation belts

open access: yesFrontiers in Physics
Solar forcing and geomagnetic disturbances reshape radiation-belt electron populations through a chain of coupled processes that cannot be represented adequately by a single activity index.

Mortars From Punic and Hellenistic–Roman Solunto: Materials, Formulations, and Technology

open access: yesArchaeometry, EarlyView.
ABSTRACT This study presents an archaeometric investigation of 18 hydraulic rendering and bedding mortars from Punic and Hellenistic–Roman Solunto (NW Sicily). The research aimed to characterize raw materials, reconstruct manufacturing sequences, and evaluate technological proficiency through mineralogical and petrochemical analyses.

Neural Networks and Multivariate Analysis Based on Geochemical Data to Determine Stone Provenance From Ancient Calabrian Quarries (Southern Italy)

open access: yesArchaeometry, EarlyView.
ABSTRACT This study shows an innovative approach to determine the origin of some Calabrian rocks quarried used in ancient times. Twenty‐five quarries, distributed in all the Calabrian provinces (Southern Italy), were studied and sampled. Ten samples were taken from each quarry, for a total of 250 samples.
