Modeling Atmospheric Ion Escape from Kepler-1649 b and c over Time
The Astrophysical Journal LettersRocky planets orbiting M dwarf stars are prime targets for atmospheric characterization, yet their long-term evolution under intense stellar winds and high-energy radiation remains poorly constrained.

Overcoming the Limitations of the Energy-limited Approximation for Planet Atmospheric Escape [PDF]
Astrophysical Journal, 2018 Studies of planetary atmospheric composition, variability, and evolution require appropriate theoretical and numerical tools to estimate key atmospheric parameters, among which the mass-loss rate is often the most important.

Escape of Gases from Atmospheres [PDF]
Nature, 1904 IN a recent number of NATURE (January 14) there appears an article on the above subject by Dr. G. Johnstone Stoney, in which he corrects a statement in the literary supplement of the Times of December 25, 1903, in regard to the escape of helium from the earth's atmosphere.

Advanced Healthcare Materials, EarlyView.Under NIR irradiation, PTCPP generates ROS to eliminate MRSA biofilms and promote M1 macrophage polarization for phagocytosis. After bacterial clearance, the material is phagocytosed by macrophages, shifting their polarization to M2 phenotype via metabolic reprogramming, which synergistically enhances anti‐infection therapy and wound healing.

Ionospheric Plasma Transported Into the Martian Magnetosheath
Geophysical Research LettersHeavy cold ions at Mars are gravitationally bound to the planet unless some process provides energy to them. Observations show that cold (1 cm−3) O+/O2+ ions with bulk velocities equal to energies ∼1 keV can reach deep into the nightside Martian ...

The XUV irradiation and likely atmospheric escape of the super-Earth π Men c [PDF]
Monthly Notices of the Royal Astronomical Society Letters, 2019 π Men c was recently announced as the first confirmed exoplanet from the TESS mission. The planet has a radius of just 2 R⊕ and it transits a nearby Sun-like star of naked-eye brightness, making it the ideal target for atmospheric characterization of a ...

Advanced Healthcare Materials, EarlyView.A novel photodynamic therapeutic approach has been employed for anticancer therapy, utilizing chlorin e6‐loaded Pluronic nanocapsules and a wearable organic light‐emitting diode light source. This has shown significant in vivo antitumor efficacy with minimal off‐target toxicity. The innovative combination of a wearable light source and photosensitizers

Narrow Loophole for H2-Dominated Atmospheres on Habitable Rocky Planets around M Dwarfs
The Astrophysical Journal Letters, 2023 Habitable rocky planets around M dwarfs that have H _2 -dominated atmospheres, if they exist, would permit characterizing habitable exoplanets with detailed spectroscopy using JWST, owing to their extended atmospheres and small stars.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing
Advanced Materials, EarlyView.This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...
