Wildfire Emissions From European Boreal Fuels: Effects of Fuel Type and Moisture Content

Fire and Materials, EarlyView.
ABSTRACT The increasing severity of wildfires poses significant challenges through the release of greenhouse gases and other harmful gases and particles. Although field measurements exist, there is a lack of systematic data collection to understand the influence of moisture content on the particle and gas emissions of boreal fuels, particularly for ...

Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

FlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...

Correlating Mid‐Infrared Absorption With Radiative Efficiency in Passive Daytime Radiative Cooling Systems

Macromolecular Rapid Communications, EarlyView.
We establish a correlation between the mid‐IR photonic response of Passive Daytime Radiative Cooling systems and their thermal radiation performances, characterized within a dedicated setup that simulates the irradiance toward outer space under controlled and reproducible conditions.

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks

Macromolecular Rapid Communications, EarlyView.
Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Physics‐Informed Generative Machine Learning for Designing Crack‐Free γ′‐Strengthened Ni‐Based Superalloys for Laser Powder Bed Fusion

Materials Genome Engineering Advances, EarlyView.
This research proposes a physics‐informed generative machine learning framework to design SHA800, a crack‐free γ′‐strengthened nickel‐based superalloy for laser powder bed fusion, achieving a 43% γ′ volume fraction and 587 HV0.2 hardness. ABSTRACT Fabricating γ′‐strengthened nickel‐based superalloys via laser powder bed fusion (LPBF) faces significant ...

Effect of Nanosilica Aggregates/Agglomerates on Functional Properties of Poly(Butylene 2,5‐Furandicarboxylate)‐Based Nanocomposites

Polymer Composites, EarlyView.
Effect of nanosilica aggregates/agglomerates on oxygen and water vapor diffusivity of PBF/SiO2 nanocomposites. ABSTRACT The nanofillers inclusions in poly(butylene 2,5‐furandicarboxylate) (PBF)/SiO2 nanocomposites were found to consist of aggregates and agglomerates of nanosilica particles.

Quantitative Evaluation of Surface Whitening Mitigation via Thermal Annealing in Carbon Fiber/Polyphenylene Sulphide Thermoplastic Composite Laminates

Polymer Composites, EarlyView.
Mitigation of surface whitening in CF/PPS laminates via thermal annealing and quantitative image‐based assessment. ABSTRACT Surface whitening is a manufacturing‐induced surface defect in thermoplastic composites, resulting from non‐uniform shrinkage and near‐surface resin instability during cooling.

Combined Effects of Thermal Cycling Aging and Reinforcement Content on the Ball‐On‐Disk Wear of Additively Manufactured Polylactic Acid Composites

Polymer Composites, EarlyView.
Thermal Aging and Tribological Tests of Additive Manufactured PLA Composites. ABSTRACT This study focuses on the additive manufacturing of pure polylactic acid (PLA) specimens and milled glass fiber (GF)‐filled PLA composites under thermal cycling aging and wear tests. Wear tracks have been analyzed via 3D optical profiling and SEM imaging.
