Has Kronos Devoured Planet Nine and Its Epigones?
UniverseThe Planet Nine hypothesis encompasses a body of about 5–8 Earth’s masses whose orbital plane would be inclined to the ecliptic by one or two tens of degrees and whose perihelion distance would be as large as about 240–385 astronomical units. Recently, a

Evolution of Mercury’s Volatile-bearing Crust within Raditladi Basin
The Planetary Science JournalMercury’s surface presents significant challenges for understanding planetary volatile distribution. Previous studies have identified features including hollows, flows, and chaotic terrains as associated with the presence of volatiles.

Selective Aggregation Experiments on Planetesimal Formation and Mercury-Like Planets
Geosciences, 2018 Much of a planet’s composition could be determined right at the onset of formation. Laboratory experiments can constrain these early steps. This includes static tensile strength measurements or collisions carried out under Earth’s gravity and

Estimation of a planetary magnetic field using a reduced magnetohydrodynamic model [PDF]
Annales Geophysicae, 2017 Knowledge of planetary magnetic fields provides deep insights into the structure and dynamics of planets. Due to the interaction of a planet with the solar wind plasma, a rather complex magnetic environment is generated.

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization
Advanced Functional Materials, EarlyView.We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Stabilizing Electrochemical Interfaces With Multifunctional Cobalt Nitride Layers
Advanced Materials Interfaces, EarlyView.Cobalt nitrides emerged recently as an interesting class of earth‐abundant oxygen evolution catalysts. Herein, plasma‐enhanced atomic layer deposition is used to synthesize multifunctional cobalt nitride layers that simultaneously protect and catalytically activate photoelectrode surfaces.

An Estimate of the Importance of Electron-stimulated Desorption of Sodium at Mercury
The Planetary Science JournalWe revisit the importance of electron-stimulated Desorption (ESD) as a source of neutral sodium (Na) atoms and Na ^+ ions in Mercury’s exosphere and ionosphere.

Advanced Materials Technologies, EarlyView.Laser‐assisted synthesis enables rapid (within 1 h) and high‐yield (≥90%) production of Co‐MOFs with mesoporous structures, tunable magnetic and optical properties, and efficient adsorption of N2, CH4, and CO2 for low‐energy gas separation. DFT calculations elucidate the electronic structure and adsorption behavior.

How Does the Thermal Environment Affect the Exosphere/Surface Interface at Mercury?
The Planetary Science Journal, 2023 The fate of Mercury’s exospheric volatiles and, in a lesser way, of the refractory particles absorbed in the first few centimeters of the surface both depend highly on the temperature profile with depth and its diurnal variation. In this paper, we review
