Atmospheric Dynamics of Terrestrial Planets [PDF]

The solar system presents us with a number of planetary bodies with shallow atmospheres that are sufficiently earthlike in their form and structure to be termed “terrestrial.” These atmospheres have much in common, in having circulations that are driven ...

A Review of Grain Boundaries: Formation Mechanism, Synthesis Strategy, and Application in Electrocatalysis

EcoEnergy, EarlyView.
An overview of grain boundary engineering in the field of electrocatalysis. ABSTRACT Key electrocatalytic reactions such as HER, OER, ORR, CO2RR, and NRR offer promising routes for storing renewable energy as chemical fuels. However, their widespread application is constrained due to the lack of highly active and stable catalysts. Grain boundaries (GBs)

Forming Mercury from Excited Initial Conditions

The Astrophysical Journal
Mercury is notoriously difficult to form in Solar System simulations, due to its small mass and iron-rich composition. Smooth particle hydrodynamics simulations of collisions have found that a Mercury-like body could be formed by one or multiple giant ...

Polyoxometalates in Photocatalytic CO2 Reduction: Multielectron Redox Regulation Across Molecular and Hybrid Architectures

EcoEnergy, EarlyView.
This review focuses on multielectron redox regulation across molecular and hybrid architectures for photocatalytic CO2 reduction, covering intrinsic POM photocatalysts, photosensitizer‐assisted assemblies, POM–metal–organic complexes, and POM‐integrated semiconductors and MOF/COF heterostructures to link structural motifs with charge transport, product

Size–Frequency Distribution of Terrestrial Leftover Planetesimals and S-complex Implanted Asteroids

The Astrophysical Journal
The isotopic composition of meteorites linked to S-complex asteroids has been used to suggest that these asteroids originated in the terrestrial planet’s region, i.e., within 1.5 au, and later got implanted into the main asteroid belt (MAB).

Comparative Study of Ion Foreshocks and Ultra-Low Frequency Waves at Solar System’s Terrestrial Planets in a Global 3D Hybrid-Particle Model

URSI Radio Science Letters
Abstract – We compare the ion foreshocks of the solar system’s four terrestrial planets by applying the numerical three-dimensional (3D) global hybrid-particle model RHybrid (paRallel Hybrid). The RHybrid model is a high-performance computing framework that describes space plasma in an ion-kinetic, collisionless particle formulation with self ...

Effect of Sequential and Combined Space‐Based Stressors on Perovskite Solar Cell Stability

EcoEnergy, EarlyView.
A correlation between loss in performance and mobile ion concentration has been established by sequential stressing of perovskite solar cells under Low Earth Orbit conditions with exposure to protons, light, and thermal cycling. It is shown that the loss in performance increases when ion concentration increases and vice versa.

Two-source Terrestrial Planet Formation with a Sweeping Secular Resonance

The Astronomical Journal
The models that most successfully reproduce the orbital architecture of the solar system terrestrial planets start from a narrow annulus of material that grows into embryos and then planets.
