Morpho‐structural analysis of impact craters on Pluto: Implications for the study of complex craters

Meteoritics &Planetary Science, EarlyView.
Abstract We used Pluto's global digital elevation model to automatically perform a morphometric analysis of impact craters. Triangular irregular networks (TINs) were generated for each crater, providing a detailed representation of crater topography and enabling more accurate morpho‐structural analysis. A dedicated toolkit generated radial profiles for

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Impact provenance and age of a unique basalt found in Apollo 12 regolith

Meteoritics &Planetary Science, EarlyView.
Abstract Basaltic sample 12032,366‐18 from the Apollo 12 landing site is distinct among basalts collected at this site, other Apollo landing sites, and lunar meteorites in terms of its age, bulk rock composition, and isotopic composition. We present new Pb isotopic data obtained by in situ Secondary Ion Mass Spectrometry on multiple mineral phases in ...

Elevation shapes alpine snow algal blooms and their influence on albedo reduction

New Phytologist, EarlyView.
Graphical summary of elevational trends in Sanguina‐dominated snow algal blooms. Increasing elevation was associated with larger cells, lower Chla content per cell, higher astaxanthin ratios, lower snow water content, and reduced cell‐normalized albedo, whereas algal cell density showed no consistent elevational trend.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.
