Volatiles in the Martian regolith

open access: yesGeophysical Research Letters, 1979
An inventory of released volatiles on Mars has been derived based upon Viking measurements of atmospheric and surface chemical compositionand upon the inferred mineralogy of a ubiquitous regolithassumed to average 200m in depth. This model is consistent with the relative abundances of volatiles (except for S) on the Earth's surfacebut implies one ...

Rock Location and Property Analysis of Lunar Regolith at Chang’E-4 Landing Site Based on Local Correlation and Semblance Analysis

open access: yesRemote Sensing, 2020
The Lunar Penetrating Radar (LPR) onboard the Yutu-2 rover from China’s Chang’E-4 (CE-4) mission is used to probe the subsurface structure and the near-surface stratigraphic structure of the lunar regolith on the farside of the Moon.

Regolith grain sizes of Saturn's rings inferred from Cassini-CIRS far-infrared spectra

open access: yes, 2012
We analyze far-infrared (10-650 cm$^{-1}$) emissivity spectra of Saturn's main rings obtained by the Cassini Composite Infrared Spectrometer (CIRS). In modeling of the spectra, the single scattering albedos of regolith grains are calculated using the Mie

Scalable Gecko‐Inspired Adhesives via Diffraction‐Grated Molds: A Low‐Cost, Directional PDMS System

open access: yesEngineering Reports, Volume 7, Issue 10, October 2025.
Using diffraction gratings as master molds, we fabricated adhesives with nanoscale patterned surfaces confirmed by SEM. These structures significantly enhance directional adhesion, demonstrating a scalable approach to develop bioinspired adhesives with improved performance for robotic and biomedical applications.

Influence of catchment lithology on debris‐flow fan morphology, sedimentology and evolution—Field evidence from the White Mountains, southern California, USA

open access: yesEarth Surface Processes and Landforms, Volume 50, Issue 13, October 2025.
Morphology of the (a) Sacramento Canyon fan (with a catchment dominated by batholitic bedrock) and (b) Gunter Creek fan (with a catchment dominated by sedimentary bedrock) at the foot of the White Mountains, California, highlighting the differences between fans fed by contrasting lithologies.

Petrographic survey of lunar regolith breccias [PDF]

open access: yes
Regolith breccias from the Moon and from parent bodies of some meteorites may provide samples of ancient regoliths which have been frozen in time. If these rocks were essentially closed at some earlier time and that time can be determined, then these ...

The contamination of the surface of Vesta by impacts and the delivery of the dark material

open access: yes, 2014
The Dawn spacecraft observed the presence of dark material, which in turn proved to be associated with OH and H-rich material, on the surface of Vesta. The source of this dark material has been identified with the low albedo asteroids, but it is still a ...

Middle to Late Pleistocene valley‐slope cambering: The interglacial basin at Wing, Rutland, England

open access: yesJournal of Quaternary Science, Volume 40, Issue 7, Page 1230-1239, October 2025.
ABSTRACT A depression in the Jurassic bedrock at Wing, Rutland (eastern England), is infilled by deposits spanning the Late Wolstonian (=Late Saalian) to Early Devensian (=Early Weichselian) substages, including the most complete Ipswichian Stage (=Eemian Stage; ~Marine Isotope Stage 5e) sequence known in Britain. This sequence forms an enclosed pocket,
