Revealing Structure–Performance Relations in Core‐Shell Catalyst‐Based PEM Water Electrolyzer Anodes with Low Iridium Loading

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Table of Contents The TiO2@IrO2 core–shell architecture ensures high electronic conductivity even at a low iridium content of 10 wt%. The resulting catalyst layer shows significantly higher iridium utilization than a commercial reference, leading to improved PEMWE single‐cell performance at low iridium loading.

Radical Listening as a Governance Innovation: Integrating Planetary Health and Community‐Led Forest Conservation in Indonesia

Environmental Policy and Governance, EarlyView.
ABSTRACT While REDD+ prioritizes carbon sequestration, its narrow focus often overlooks forest‐health linkages critical to community well‐being. This paper examines the holistic model of Health in Harmony (HIH) and Alam Sehat Lestari (ASRI), which integrates forest conservation with healthcare through radical listening—a decolonial community engagement

The FemTech revolution: Unlocking the potential of new technology for optimizing pregnancy outcomes in low‐ and middle‐income countries and remote areas

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Maternal and neonatal mortality and morbidity rates uncover major global health disparities. Despite ongoing efforts, the rates of maternal and neonatal complications remain substantially higher in low‐ and middle‐income countries (LMICs) compared to high‐income countries (HICs). These high rates are the result of several unmet needs in LMICs,

Combining the Underwater Vision Profiler 6 with sediment traps to measure in situ velocity of marine particles

Limnology and Oceanography: Methods, EarlyView.
Abstract Particles sinking from the surface to the deep ocean play a key role in the biological carbon pump, whose efficiency depends partly on sinking velocities. Over the last decade, in situ imaging has enabled critical advances in our understanding of particle dynamics in the ocean.

Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

Macromolecular Rapid Communications, EarlyView.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...
