Spectral-Kinetic Synergy in Au-Network Engineered FeTiO₃: A Multi-Field Coupling Strategy for Lunar In Situ Resource Utilization. [PDF]

Adv Sci (Weinh)
How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

Epigenetic silencing of the liver-specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation. [PDF]

Mol Oncol
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Use of orbiting reflectors to decrease the technological challenges of surviving the lunar night [PDF]

, 2011
In this paper the feasibility of using lunar reflectors to decrease the technological challenges of surviving the lunar night is investigated. This is achieved by attempting to find orbits in the two-body problem where the argument of periapsis is ...

Lunar meteorite regolith breccias: an in situ study of impact melt composition using LA-ICP-MS with implications for the composition of the lunar crust [PDF]

, 2007
Dar al Gani (DaG) 400, Meteorite Hills (MET) 01210, Pecora Escarpment (PCA) 02007, and MacAlpine Hills (MAC) 88104/88105 are lunar regolith breccia meteorites that provide sampling of the lunar surface from regions of the Moon that were not visited by ...

A 3D hybrid simulation study of the electromagnetic field distributions in the lunar wake [PDF]

, 2011
As a consequence of its lack of a thick atmosphere and an ionosphere, the interaction of the solar wind with the Moon is characterized by the direct impact of the solar wind on its sunward hemisphere.

Comprehensive mapping of lunar surface chemistry by adding Chang'e-5 samples with deep learning

Nature Communications, 2023
Lunar surface chemistry is essential for revealing petrological characteristics to understand the evolution of the Moon. Existing chemistry mapping from Apollo and Luna returned samples could only calibrate chemical features before 3.0 Gyr, missing the ...
