Laser melting manufacturing of large elements of lunar regolith simulant for paving on the Moon

Scientific Reports, 2023
The next steps for the expansion of the human presence in the solar system will be taken on the Moon. However, due to the low lunar gravity, the suspended dust generated when lunar rovers move across the lunar soil is a significant risk for lunar ...

Assessing Toxicity and Nuclear and Mitochondrial DNA Damage Caused by Exposure of Mammalian Cells to Lunar Regolith Simulants

GeoHealth, 2018
Previous missions to the lunar surface implicated potential dangers of lunar soil. In future explorations, astronauts may spend weeks or months on the Moon, increasing the risk of inhaling lunar dust.

Mapping of the lunar surface by average atomic number based on positron annihilation radiation from Chang’e-1

Earth and Planetary Physics, 2018
A map of the average atomic number of lunar rock and soil can be used to differentiate lithology and soil type on the lunar surface. This paper establishes a linear relationship between the average atomic number of lunar rock or soil and the flux of ...

Plants grown in Apollo lunar regolith present stress-associated transcriptomes that inform prospects for lunar exploration

Communications Biology, 2022
Arabidopsis plants were seeded onto lunar soil samples taken directly from the Apollo 11, 12, and 17 missions. Transcriptomic analyses reveal that plants grown in lunar soil differentially express genes associated with salt, metal, and ROS stress.

An Empirical Model to Estimate Abundance of Nanophase Metallic Iron (npFe⁰) in Lunar Soils

Remote Sensing, 2020
Lunar soils gradually become mature when they are exposed to a space environment, and nanophase metallic iron (npFe0) generates within them. npFe0 significantly changes the optical properties of lunar soils and affects the interpretation of the remotely ...

Design and Verification of a Novel Sampling System for Lunar Water Ice Exploration

IEEE Access, 2023
Aiming at the problem that it is difficult to collect the subsurface lunar water ice samples quickly due to the cementation-hardening of ice and soil at extremely low temperature in the permanent shadow regions, a novel lunar water ice sampling system is

Mellitic Acid as a Stable Abiotic Precursor for Liquid‐Liquid Phase Separation: An RNA‐Independent Pathway for Prebiotic Compartmentalization

Chemistry – A European Journal, EarlyView.
Evidence is presented that prebiotically accessible mellitic (benzenehexacarboxylic) acid (MAc) is forming liquid droplets with short poly‐L‐lysine. The capacity of MAc to induce liquid‐liquid phase separation with short oligocations, along with abiotic synthesis routes, makes MAc a viable candidate for an ingredient of early prebiotic membraneless ...

Synergistic Co‐Pyrolysis of Tannery Sludge and Oyster Shells for Enhanced Chromium Speciation Transformation and Recovery Efficiency

CleanMat, EarlyView.
Oyster shell (OS) as a sustainable calcium source for chromium recovery from tannery sludge via co‐pyrolysis. OS outperformed CaCO3, achieving > 95% Cr recovery, attributed to its organic matrix proteins enhancing adsorption and phase conversion. The oxidation of tannery sludge Cr(III) to Cr(VI) improved recyclability, aligning with circular economy ...
