Mg2+ Ions as Interfacial Charge Bridges for Enhanced Photocatalytic Hydrogen Evolution in Poly(Heptazine Imide)

Small, EarlyView.
Mg2+ confined within poly(heptazine imide) acts as a heterogenized interfacial charge bridge capable to couple synergistically the semiconductor with Pt co‐catalysts, thus enhancing hydrogen evolution. Through water polarization and hydroxide stabilization, a dynamic Mg2+‐OHδ−‐Hδ+‐Pt motif facilitates proton transfer and overcomes interfacial electron ...

Duct Effect of Magnetic Dips on the Propagation of EMIC Waves in Jupiter's Magnetosphere With Observations of Juno

Geophysical Research Letters
In recent years, it has been found that magnetic dip caused by diamagnetic motion of injected plasma can provide an appropriate environment for excitation of electromagnetic ion cyclotron (EMIC) waves.

Carbon Coating Strategies to Enhance the Performance and Stability of LiMn0.6Fe0.4PO4 in Lithium‐Ion Batteries

Small, EarlyView.
Six unique carbon coating methods are applied to the synthesis of LiMn0.6Fe0.4PO4. The electrochemical performance of the synthesized LiMn0.6Fe0.4PO4 in full cells depends on the uniformity and conductivity of the carbon coating produced. Transition‐metal dissolution is effectively reduced when the carbon coating is optimized as a protective layer ...

Quantifying and Tracking Flexibility of System Elements to Support (Re)Design Decision‐Making

Systems Engineering, EarlyView.
ABSTRACT Evolving objectives and requirements, risk management processes, and external disruptions frequently drive change in engineered systems. Due to these pressures, system architects must anticipate and manage change throughout a system's lifecycle. Yet, managing change is challenging due to the risk of change propagation.

Global Effects of Chorus and Hiss Waves on Trapped Energetic Electrons at Jupiter

Geophysical Research Letters
Unlike Earth, where whistler‐mode chorus is generally observed outside the plasmasphere and hiss is predominantly confined within it, Jupiter's magnetosphere frequently hosts both wave modes simultaneously.

Exploring Microencapsulated Magnesium Tetraborate: A Promising Flame‐Retardant Additive for Polyurethane‐Based Composites

Journal of Vinyl and Additive Technology, EarlyView.
Flame‐retardant polyurethane composites were synthesized by in situ polymerization. Fire performance and thermal decomposition of boron‐bearing compounds in PU were examined. ABSTRACT Boron compounds exhibit low toxicity and diverse molecular structures, rendering them effective flame‐retardant additives in polymer‐based materials through various ...

Changes in the Plasma Sheet Conditions at Europa's Orbit Retrieved From Lead Angle of the Satellite Auroral Footprints

Geophysical Research Letters
The electromagnetic interaction between Europa and the plasma sheet in the Jovian magnetosphere generates Alfvén waves, ultimately generating auroral footprints in Jupiter's atmosphere.

Male production in green sea turtles under a feminizing climate: A validated model of sex ratios with temperature‐dependent sex determination

Journal of Animal Ecology, EarlyView.
This study introduces validated methods to predict sex ratios in wild Green sea turtle (Chelonia mydas) nests. It quantifies beach‐scale temperature heterogeneity, incorporates clutch‐level variation in thermal sensitivity and models temperature effects across the thermosensitive period, demonstrating how temporal temperature dynamics and spatial ...

PRECARIZED AGEING‐IN‐PERIFERIA: Low‐Income Older Adults in a Transforming Neighbourhood

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article we investigate how intersecting forms of precarity shape the everyday practices of ageing‐in‐place developed by low‐income older adults in Via Milano, a historically segregated yet rapidly transforming neighbourhood in Brescia, northern Italy. We draw on qualitative and ethnographic research to examine how diverse urban changes—
