3D Modeling of Lacus Mortis Pit Crater with Presumed Interior Tube Structure [PDF]
Journal of Astronomy and Space Sciences, 2015 When humans explore the Moon, lunar caves will be an ideal base to provide a shelter from the hazards of radiation, meteorite impact, and extreme diurnal temperature differences.

Engineering Energy Harvesting Pathways in Mn‐Yb‐Doped Perovskite Nanocrystals
Advanced Optical Materials, EarlyView.Mn‐Yb codoping in metal halide perovskite nanocrystals establishes dual‐channel energy reservoirs that capture charge carriers and drip‐feed them back to the host on millisecond timescales. This synergistic recycling mechanism overcomes prompt nanosecond recombination limitations, enabling an eight‐fold enhancement in photocatalytic CO2 reduction ...

Highlighting the History of French Radio Astronomy. 4. Early Solar Research at the École Normale Supérieure, Marcoussis and Nancay [PDF]
, 2009 The first tentative steps in solar radio astronomy took place during the 1940s and early 1950s as physicists and engineers in a number of countries used recycled World War II equipment to investigate the flux levels and polarisation of solar bursts and ...

Invariant manifolds and orbit control in the solar sail three-body problem [PDF]
, 2008 In this paper we consider issues regarding the control and orbit transfer of solar sails in the circular restricted Earth-Sun system. Fixed points for solar sails in this system have the linear dynamical properties of saddles crossed with centers; thus ...

Unveiling the Mechanism for the Rapid Acceleration Phase in a Solar Eruption
The Astrophysical Journal Letters, 2023 Two major mechanisms have been proposed to drive the solar eruptions: the ideal magnetohydrodynamic instability and the resistive magnetic reconnection. Due to the close coupling and synchronicity of the two mechanisms, it is difficult to identify their ...

Solar flux emergence : a three-dimensional numerical study [PDF]
, 2008 Flux is continually emerging on the Sun, making its way from the solar interior up into the atmosphere. Emergence occurs on small-scales in the quiet Sun where magnetic fragments emerge, interact and cancel and on large-scales in active regions where ...
