The evaporation of planetary atmospheres

Contributions of the Astronomical Observatory Skalnaté Pleso
In recent years the focus of exoplanet research has shifted from the mere detection to detailed characterization. Precise measurements of the masses and radii of transiting planets have shown that some low-mass planets have extended atmospheres while others are bare rocks. Hybrid atmospheres consisting of a mixture of Hydrogen and large amount of heavy

Development of a Novel Processing Route for Dispersoid/Precipitation‐Strengthened High Conductive Copper Alloys by Using Metalized Nanoceramics in Additive Manufacturing

Advanced Engineering Materials, EarlyView.
This study explores a process chain to produce dispersoid‐strengthened CuCr1Zr for applications requiring high strength and conductivity. Using gas‐atomized powder and copper‐plated alumina nanoparticles, additive manufacturing is performed via powder bed based additive manufacturing with green and red lasers, followed by heat treatment.

Hydrodynamic simulations of captured protoatmospheres around Earth-like planets

, 2015
Young terrestrial planets, when they are still embedded in a circumstellar disk, accumulate an atmosphere of nebula gas. The evolution and eventual evaporation of the protoplanetary disk affect the structure and dynamics of the planetary atmosphere ...

Environmentally Stable and Highly Crystalline MXenes for Multispectral Electromagnetic Shielding up to Millimeter Waves

Advanced Functional Materials, EarlyView.
This study presents excellent EMI shielding effectiveness of highly crystalline HC‐Ti3C2Tx MXene, characterized by high electrical conductivity, outstanding environmental stability, and facile processability, across a multispectral frequency range from 100 kHz to 110 GHz. It is revealed that increasing the thickness and electrical conductivity of MXene

Detection and Localization of Stationary Waves on Venus Using a Self‐Supervised Anomaly Detection Model

Journal of Geophysical Research: Machine Learning and Computation
The atmosphere of Venus features stationary waves of planetary scale, which are believed to be caused by wind flowing over elevated terrains. Detecting these waves can provide valuable insight into atmospheric dynamics.

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow

Advanced Functional Materials, EarlyView.
Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

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

The 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 ...
