Comparison of terrestrial exospheric hydrogen 3D distributions at solar minimum and maximum using TWINS Lyman-α observations

Frontiers in Astronomy and Space Sciences
Remote sensing observations of far-ultraviolet (FUV) emissions have been used to estimate 3D neutral hydrogen (H) density models of the terrestrial exosphere under solar minimum (2008) and solar maximum (2013 and 2015) conditions.

Designed Lewis Acid–Base Passivation for High Performance Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
ABSTRACT Silicon's high cost and long energy payback time remain major barriers to the global expansion of solar power. In contrast, metal–halide perovskites offer abundant, solution‐processable absorbers, and have achieved efficiencies of 25%–30%, positioning them as strong competitors to silicon.

Tracing the Winds: A Uniform Interpretation of Helium Escape in Exoplanets from Archival Spectroscopic Observations

The Astrophysical Journal
Over the past decade, observations of evaporating exoplanets have become increasingly common, driven by the discovery of the near-infrared helium-triplet line as a powerful probe of atmospheric escape.

MXene Wrapped Magnetic Mesocrystals for Durable Redox Catalytic Cancer Therapy and Responsive MRI

Advanced Functional Materials, EarlyView.
Conformal wrapping of ultrathin Ti3C2Tx MXene nanosheets on Fe3O4 mesocrystals creates topology‐stabilized Schottky junctions that direct photoinduced electron transfer under NIR irradiation. The unique architecture sustains Fenton catalysis, promotes continuous hydroxyl radical production, and provides photo‐responsive MRI contrast.

Future atmospheric CO2 leads to delayed autumnal senescence

, 2007
Growing seasons are getting longer, a phenomenon partially explained by increasing global temperatures. Recent reports suggest that a strong correlation exists between warming and advances in spring phenology but that a weaker correlation is evident ...

HST PanCET program: non-detection of atmospheric escape in the warm Saturn-sized planet WASP-29 b

, 2021
Short-period gas giant exoplanets are susceptible to intense atmospheric escape due to their large scale heights and strong high-energy irradiation.

One‐Step Microfluidic Manufactured Fucose‐Decorated Sweetosomes Choose the Time and the Road for Their Intracellular Journey to Cancer Treatment

Advanced Healthcare Materials, EarlyView.
Sweetosomes, a new class of fucose‐decorated liposomes, are developed via a one‐step microfluidic process without surface chemistry. This study elucidates their main caveolae‐mediated entry and distinct endosomal trafficking. These nanostructures demonstrate superior endosomal escape, organelle acidity modulation, and prolonged plasma persistence ...

Fluid∕Kinetic Hybrid Simulation of Atmospheric Escape: Pluto

, 2011
A hybrid fluid/molecular kinetic model was developed to describe the escape of molecules from the gravitational well of a planet's atmosphere. This model was applied to a one dimensional, radial description of molecular escape from the atmosphere of ...

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.
