A SYSTEMATIC RETRIEVAL ANALYSIS OF SECONDARY ECLIPSE SPECTRA. III. DIAGNOSING CHEMICAL DISEQUILIBRIUM IN PLANETARY ATMOSPHERES [PDF]

open access: yes, 2013
Chemical disequilibrium has recently become a relevant topic in the study of the atmospheres of transiting extrasolar planets, brown dwarfs, and directly imaged exoplanets.

Self‐Assembled Gallium Sulfide (GaS) Heterostructures Enabling Efficient Water Splitting and Selective Ammonia Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Gallium sulfide (GaS) forms self‐assembled heterostructures with its native oxide, exhibiting high performance in water splitting and ultrasensitive and selective ammonia detection. Surface defects and controlled oxidation enhance catalytic activity and sensing response.

Scattering Blanketing Effect of Earth’s Proto-atmosphere: Enhanced Suppression of Planetary Radiation and Magma Ocean Cooling

open access: yesThe Astrophysical Journal
The thermal evolution of magma oceans formed by giant impacts is strongly influenced by a proto-atmosphere through its blanketing effect, which suppresses outgoing planetary radiation.

Terminator Habitability: The Case for Limited Water Availability on M-dwarf Planets

open access: yesThe Astrophysical Journal, 2023
Rocky planets orbiting M-dwarf stars are among the most promising and abundant astronomical targets for detecting habitable climates. Planets in the M-dwarf habitable zone are likely synchronously rotating, such that we expect significant day–night ...

Meteoric Layers in Planetary Atmospheres [PDF]

open access: yesSpace Science Reviews, 2008
Metallic ions coming from the ablation of extraterrestrial dust, play a significant role in the distribution of ions in the Earth’s ionosphere. Ions of magnesium and iron, and to a lesser extent, sodium, aluminium, calcium and nickel, are a permanent feature of the lower E-region.

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

The chemistry of planetary atmospheres [PDF]

open access: yesJournal of Chemical Education, 1976
Present knowledge concerning the chemistry of planetary atmospheres is reviewed along with the theories which attempt to explain observational data. The known gross atmospheric compositions of the terrestrial and giant planets are listed, differences between the atmospheres of earth and Venus are discussed, and the atmospheres of the giant planets are ...

Differentiating the Synergistic Interactions Between Li+ Salts and Cyclic to Linear Carbonate Ratios to Enable Wide‐Temperature Performance of Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
The coordination in carbonate solvents and degradation products of lithium difluoro(oxolato) borate (LiDFOB) salt enables sufficient passivation of both LiNi0.8Mn0.1Co0.1O2 (NMC811) cathode and graphite anode in the absence of ethylene carbonate (EC).

The Interplay of Surface Composition, Mineralogy, and Physical Conditions That Affect the Surface Release Processes and Particle Environment of Mercury

open access: yesThe Planetary Science Journal
Mercury has a very tenuous atmosphere starting at the surface, which is referred to as a surface-bound exosphere, where there are no collisions between exospheric particles.

The Possible role of Penning Ionization Processes in Planetary Atmospheres

open access: yes, 2015
In this paper we suggest Penning ionization as an important route of formation for ionic species in upper planetary atmospheres. Our goal is to provide relevant tools to researchers working on kinetic models of atmospheric interest, in order to include ...
