Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, EarlyView.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

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 ...

‘Who is the Gael who Would Not Weep?’: The Book of the O’Conor Don, Fearghal Óg Mac an Bhaird, and Late Bardic Poetry of Exile

Renaissance Studies, EarlyView.
Abstract This article examines how late bardic poetry transforms the condition of exile into a literary mode that reimagines community and tradition. I argue that poetry of lament, blessing and devotion articulates a broader literary consciousness that anticipates modern notions of a national consciousness. The compilation of bardic verse in manuscript

Using Local Expert Knowledge to Measure Prices: Evidence From a Survey Experiment in Vietnam

Review of Development Economics, EarlyView.
ABSTRACT Many countries lack spatially disaggregated consumer price data needed to estimate real inequality and spatial patterns of poverty. Such data are especially absent in poor countries where weak infrastructure and high transport costs create large price variation over space.
