Rational Design of Multifunctional Nano–Architected Coatings for Bipolar Plates in Proton Exchange Membrane Fuel Cells

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Proton exchange membrane fuel cells (PEMFCs) require advanced bipolar plate coatings to enhance efficiency, durability, and commercialization potential. This review presents a systematic framework for evaluating and designing bipolar plate coatings, integrating material selection, performance metrics, deposition techniques, and future ...

Scutellaria Baicalensis‐Derived Carbon Dots Alleviate Colitis by Activating Anti‐Inflammatory and Barrier‐Protective Cascades

open access: yesSmall Structures, Volume 7, Issue 3, March 2026.
Using traditional Chinese medicine Scutellaria baicalensis as a precursor, CDs were synthesized through carbonization, microwave, and hydrothermal methods. Among these, Hydro‐CDs exhibited optimal biocompatibility and potent anti‐inflammatory and antioxidant activities.

‘Three Circles’: Winston Churchill's Approach to International Relations

open access: yesHistory, Volume 111, Issue 395, Page 155-167, March 2026.
ABSTRACT This article introduces a special issue that explores Winston Churchill's relationship with different countries. As its starting point, this piece takes Churchill's world view that Britain derived her status from its position at the focal point of three intersecting circles: Europe, the British Empire and the wider English‐speaking world ...

Climate Change, Air Quality, and Pollen Allergies—State of the Art and Recommendations for Research and Public Health

open access: yesAllergy, Volume 81, Issue 3, Page 663-683, March 2026.
ABSTRACT Allergies are one of the major health challenges of our time, associated with a high individual burden of disease and high costs for the healthcare system. Given their prevalence, allergies are also highly relevant from a public health perspective. The development of allergic diseases is multifactorial. In addition to individual factors (e.g.,

Aerosol and NOx emission factors and submicron particle number size distributions in two road tunnels with different traffic regimes [PDF]

open access: yesAtmospheric Chemistry and Physics, 2006
Measurements of aerosol particle number size distributions (18–700 nm), mass concentrations (PM2.5 and PM10) and NOx were performed in the Plabutsch tunnel, Austria, and in the Kingsway tunnel, United Kingdom.

Deep Convection‐Driven Downward Transport of Trace Gases and Aerosols From the Free Troposphere to the Boundary Layer

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Deep convective clouds regulate Earth's energy and moisture budgets, yet their impact on the atmospheric boundary layer (BL) composition remains underexplored. Using long‐term observations from three mid‐latitude sites, we show that deep convection (DC) consistently enhances nighttime surface ozone and is often accompanied by modest increases ...

Semi‐Volatile Organic Partitioning Improves Simulation of Biomass Burning Aerosol Mixing State Evolution

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Biomass burning aerosols significantly contribute to atmospheric composition and radiative forcing, with black carbon (BC) mixing states critically influencing optical properties and climate impacts. Recent field observations reveal a systematic three‐phase evolution in BC coating thickness during plume aging: rapid initial growth, quasi ...

Non‐Volatile Particulate Matter as Cores Driving Aerosol Mixing States and Light Absorption

open access: yesGeophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The mixing state of light‐absorbing particles critically influences aerosol optical properties, thereby affecting global radiative forcing. This study focuses on non‐volatile particulate matter (NV‐PM)—the fraction remaining after thermal denudation at 300°C—has received limited attention.
