Multi-Platform Integrated Analysis of the Degradation Patterns of Impact Crater Populations on the Lunar Surface

open access: yesRemote Sensing
Following the processing of the Chang’e-4 satellite images, Chang’e-4 landing camera images, and Yutu-2 panoramic camera images, data were obtained in a variety of resolutions, including digital elevation model (DEM) and digital orthophoto map (DOM).

A Study on the Autonomous Detection of Impact Craters

open access: yes, 2022
Planet surface studies is one of the most popular research areas in planetary science, as it is useful to attain information about a planet's history and geology without directly landing on its surface. Autonomous detection of craters has been of particular interest lately, especially for Mars and Lunar surfaces.

Beyond Thin Film Limits—Superhard and Hydrogen‐Free Amorphous Carbon Coatings With Over 100 µm Thickness

open access: yesAdvanced Functional Materials, EarlyView.
For the first time, an extreme‐thick laser‐arc PVD ta‐C (DLC) coating exceeding 100 µm is demonstrated, opening up new possibilities for ultra‐high load bearing capacity. This superhard amorphous carbon architecture combines >50% sp3 bonding, robust adhesion and self‐supporting performance, shielding substrates from plastic flow under extreme contact ...

An Updated Catalog of Rayed Craters on Mars

open access: yesEarth and Space Science, 2023
Martian meteorites represent the only samples of Mars available for study in terrestrial laboratories. In addition to their crystallization and surface ejection ages, these samples provide a detailed understanding of the geochemistry of the martian crust.

The Impact Cratering Record of Fennoscandia [PDF]

open access: yesEarth, Moon, and Planets, 1996
The current database of craterform structures in Fennoscandia contains 22 structures of impact origin and about fifty other structures which lack sufficient evidence for impact. The discovery rate of new structures has been one or two per year during the past ten years.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

open access: yesAdvanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Vascularized Liver‐on‐a‐Microsphere Reveals Alanine‐Glucose Metabolism‐Driven Regulation of Liver Function and Injury

open access: yesAdvanced Science, EarlyView.
A vascularized liver‐on‐a‐microsphere system is developed to recreate lobule‐like cellular organization and endothelial barrier function within compartmentalized hydrogel particles. The platform enhances hepatic performance and reveals alanine‐glucose cycle activation linked to improved detoxification capacity, offering a high‐throughput microscale ...

Popigai and Chicxulub craters: multiple impacts and their associated grabens [PDF]

open access: yesSolid Earth
More advanced data (gravity field model EIGEN 6C4 including the GOCE gradiometry data instead of EGM 2008) and a more sophisticated method (using a set of gravity aspects instead of gravity anomalies and the radial second derivative of the disturbing ...

Impact Crater Morphometry on Pluto: Implications for Surface Composition and Evolution

open access: yesThe Planetary Science Journal, 2023
New Horizons showed that Pluto exhibits a wide range of geologic groups, with much of the surface modified by volatile ice processes. Impact craters are a valuable tool to investigate how these regions have evolved, as they record the effects of various ...

Bio‐Inspired Gradient Coatings Enhance the Leading Edge Erosion Resistance of Wind Blades

open access: yesAdvanced Science, EarlyView.
Rain‐induced erosion of the wind turbine blade leading edge poses a critical challenge to maintenance and operation. Here, we propose a bio‐inspired approach for erosion protection utilising a platelet‐reinforced polyurethane coating with a graded through‐thickness architecture.
