Structural and Mechanical Dynamics of Polymer Membranes Across Multilength Scales

open access: yesAdvanced Science, EarlyView.
Distinct surface‐to‐bulk mechanical contrasts in polymer membranes were unveiled, highlighting the need to probe both regions to fully capture their functional behavior. By integrating in situ SAXS–WAXS with AFM‐based nanomechanics, nanodomain‐level heterogeneity and real‐time structural transformations induced by thermal and mechanical stimuli were ...

Updated model of cosmic-ray-induced ionization in the atmosphere (CRAC:CRII_v3): Improved yield function and lookup tables

open access: yesJournal of Space Weather and Space Climate
Cosmic rays, including galactic cosmic rays and solar energetic particles, form the main source of ionization of the low and middle atmosphere, which is important for various chemical and physical effects in the atmosphere.

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC

open access: yesAdvanced Electronic Materials, EarlyView.
A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.

Effects of Magnetic Boundary Layer on Galactic Cosmic Rays during the Heliopause Crossing for Voyager 2

open access: yesThe Astrophysical Journal
Voyager 2 crossed the heliopause in 2018 and observed a small-amplitude modulation of galactic cosmic rays beyond the heliopause, within a boundary layer approximately 0.57 au thick. Prior to this, it detected a similar boundary layer for both the cosmic

Integrating Automated Electrochemistry and High‐Throughput Characterization with Machine Learning to Explore Si─Ge─Sn Thin‐Film Lithium Battery Anodes

open access: yesAdvanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
A closed‐loop, data‐driven approach facilitates the exploration of high‐performance Si─Ge─Sn alloys as promising fast‐charging battery anodes. Autonomous electrochemical experimentation using a scanning droplet cell is combined with real‐time optimization to efficiently navigate composition space.

Prospects for Detecting Cosmic Filaments in Lyα Emission across Redshifts z = 2–5

open access: yesThe Astrophysical Journal
The standard ΛCDM cosmological model predicts that a large amount of diffuse neutral hydrogen distributes in cosmic filaments, which could be mapped through Ly α emission observations.

Conversion Therapy for cT4b and M1 Esophageal Squamous Cell Carcinoma: A Comprehensive Systematic Review

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
We systematically reviewed conversion therapy for esophageal squamous cell carcinoma and propose a response‐based treatment strategy for cT4b and M1 disease. For cT4b, we emphasize definitive chemoradiotherapy with timed re‐evaluation and selective salvage or chemoselection to surgery; for M1, conversion is reserved for limited‐burden responders with ...

Standard Cosmic Ray Energetics and Light Element Production

open access: yes, 2000
The recent observations of Be and B in metal poor stars has led to a reassessment of the origin of the light elements in the early Galaxy. At low it is metallicity ([O/H] < -1.75), it is necessary to introduce a production mechanism which is independent ...

Decoding Tattoo and Permanent Makeup Pigments: Linking Physicochemical Properties to Absorption, Distribution, Metabolism, and Elimination Profiles Using Quantitative Structure–Activity Relationship (QSAR)‐Based New Approach Methodologies (NAMs)

open access: yesAdvanced Intelligent Discovery, EarlyView.
This study applies QSAR‐based new approach methodologies to 90 synthetic tattoo and permanent makeup pigments, revealing systemic links between their physicochemical properties and absorption, distribution, metabolism, and elimination profiles. The correlation‐driven analysis using SwissADME, ChemBCPP, and principal component analysis uncovers insights
