Dark aeolian sediments in Martian craters: Composition and sources [PDF]

, 2011
Our research focuses on the mineralogical characteristics of dark sediment deposits in Martian craters (dunes, dune fields, and sand sheets) and their local sediment sources, carried out on the basis of 70 selected localities.

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

Advanced 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

Advanced 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 ...

The Sedimentary records of the Hapcheon impact crater basin in Korea over the past 1.3 Ma

Frontiers in Earth Science, 2023
The Hapcheon impact crater is the only meteorite impact crater identified on the Korean peninsula. However, the morphology of the impact crater and the nature of the meteorite collision are unknown. In this study, we analyzed the sedimentary facies using

Ancient Impact and Aqueous Processes at Endeavour Crater, Mars [PDF]

, 2012
The rover Opportunity has investigated the rim of Endeavour Crater, a large ancient impact crater on Mars. Basaltic breccias produced by the impact form the rim deposits, with stratigraphy similar to that observed at similar-sized craters on Earth ...

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

Advanced 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.

TiO6 as a Compensatory Structural Unit in Co‐Free, High‐Ni Layered Oxide for Durable Lithium‐Ion Batteries

Advanced Science, EarlyView.
Ti substitution stabilizes Co‐free high‐Ni layered oxides through both structural and electronic effects. TiO6 octahedra act as compensatory structural units that help interrupt cooperative Jahn–Teller distortion and suppress detrimental phase transitions, while the electron‐withdrawing inductive effect of Ti stabilizes the oxygen lattice. As a result,

Atmospheric effects on high-velocity impact cratering in porous sandstones [PDF]

EPJ Web of Conferences
Granular geomaterials feature varied porosity and may possess pore fluids. The interactions between grains, pores, and pore fluids affect the impact dynamics in the material such as the cratering efficiency, ejecta kinetics and crater morphology. In this

Electrolyte Interfacial Reactivity Regulates Alloying Anode Pulverization

Advanced Energy Materials, EarlyView.
Electrolyte interfacial reactivity governs the degradation of micrometer‐sized alloying anodes by dictating grain refinement and SEI growth. A high‐reactivity ester‐based electrolyte drives pulverization into fine nanoparticles encapsulated by a thick SEI, forming dense electrodes, whereas a low‐reactivity ether‐based electrolyte enables porous ...
