Understanding Multiscale Lithium Transport Dynamics in Composite Si‐C Electrodes: An Asymptotic Framework for GITT Experiments

open access: yesBattery Energy, Volume 5, Issue 3, May 2026.
This study introduces an asymptotic analysis to elucidate the multi‐scale transport mechanisms driving the relaxation dynamics in GITT experiments on composite Si‐C/graphite electrodes. The approach not only enhances physical understanding of coupled lithium transport mechanisms but also establishes a base for redesigning GITT protocols to achieve more

Fossil Hegemony and Capitalist Realism in Tropic of Orange

open access: yesFuture Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT This article examines Karen Tei Yamashita's Tropic of Orange (1997) through the lens of Mark Fisher's influential concept ‘capitalist realism’. Scholars of petrofiction have pointed to a political ambivalence in the representation of fossil fuels, where a better understanding of fossil capital can overwhelm as much as galvanize.

Policy Responses to the COVID‐19 Pandemic in High‐Income Countries and the Associated Maternal‐Infant Health Outcomes: A Systematic Literature and Policy Review

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Foreseeing how policy impacts pregnant women and infants is limited by ethical challenges of experimental research within these groups. The COVID‐19 pandemic generated natural experiments, offering rare opportunities to explore associations between specific policy responses and maternal‐infant health outcomes.

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.
