Verification and Mitigation of Proton‐Induced Non‐Ionizing Damage in Perovskite Solar Cells for Space Applications

open access: yesAdvanced Energy Materials, EarlyView.
Metal‐halide perovskite solar cells offer high‐efficiency power for orbital missions but suffer from permanent proton‐induced degradation. This work identifies non‐ionizing energy loss (NIEL) as the primary driver of irreversible failure, inducing atomic displacements and microcracks in the high‐fluence regime. Through energy‐tuned mapping and scalable

Application of Machine Learning Techniques to Distinguish between Mare, Cryptomare, and Light Plains in Central Lunar South Pole−Aitken Basin

open access: yesThe Planetary Science Journal
We apply machine learning techniques to identify and map resurfacing units in the central South Pole−Aitken (SPA) basin using three Lunar Reconnaissance Orbiter (LRO) mission data sets: 321/415 nm and 566/689 nm band reflectance ratios from Hapke ...

Morphological and morphometric aspects of the equine aortic valve: New insights for comparative studies in mammals

open access: yesThe Anatomical Record, EarlyView.
Abstract New data on the equine aortic valve obtained using advanced techniques is especially important given the greater availability of animal models for translational research. Here we characterized the morphological and morphometric aspects of the equine aortic valve from 60 healthy hearts collected at equine abattoirs.

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

open access: yesThe Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

The Faustini Permanently Shadowed Region on the Moon

open access: yesThe Planetary Science Journal
Faustini crater (41 km diameter) hosts a large (664 km ^2 ) permanently shadowed region (PSR) with a high potential to harbor water-ice deposits. One of the 13 candidate Artemis III landing areas contains a portion of the crater rim and proximal ejecta ...

Yutu-2 Radar Observations at the Chang’E-4 Landing Site: The Shallow Geological Structure and Its Dielectric Properties

open access: yesUniverse, 2023
China has successfully carried out five lunar exploration missions since 2007. These missions indicate that China has successfully implemented a three-step lunar exploration program of “orbiting, landing, and returning”. Among them, the Lunar Penetrating

Lunar Reconnaissance Orbiter Science Targeting Meeting : Arizona State University, Tempe, Arizona, June 9-11, 2009 [PDF]

open access: yes, 2009
A key goal of this meeting was to foster understanding of LRO capabilities and the mission planning processes necessary for high-resolution targeting of lunar features by the LRO Narrow Angle Cameras (NAC), Mini-RF synthetic aperture radar, and Diviner ...

The Strategic Role of Sustainability Certifications: A Multi‐Theoretical Framework and Comparative Analysis in the Global Wine Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Sustainability certifications are increasingly embedded in the governance and competitiveness of the wine sector, yet their strategic role remains under‐theorised. This study conceptualises certifications as multidimensional strategic mechanisms and conducts a comparative analysis of 50 schemes used in the global wine industry.

Surface Roughness of the Chang’E-6 Lunar Samples and Landing Site from Submicrometer to Kilometer Scales: Implications for Lunar Surface Processes and Remote Sensing Data Modeling

open access: yesThe Astronomical Journal
Although lunar surface roughness was studied extensively above micrometer scales before, it has not been investigated at smaller scales. In this study, we used an atomic force microscope to measure surface elevations of the Chang’E-6 lunar samples at ...
