Mechano‐Optical Behavior of Uniaxially Oriented Fluoropolymer Films: Ethylene Tetrafluoroethylene Copolymer (ETFE) and Tetrafluoroethylene Hexafluoropropylene‐ Vinylidene Fluoride Terpolymer (THV)

Polymer Engineering &Science, EarlyView.
Strain‐optical time slice study and evolution of microstructure via wide and small angle X‐ray scattering patterns and AFM images for uniaxially oriented THV and ETFE films at 145°C. ABSTRACT This study investigates morphological changes during the uniaxial orientation of two fluorinated polymers, ETFE and THV.

The iPP Printing Paradox: Interlayer Adhesion Through Crystallization

Polymer Engineering &Science, EarlyView.
In fused filament fabrication of isotactic polypropylene, high molecular weight and a high print speed increase the shear during deposition. This shear promotes the formation of the ductile β‐phase at the interphase, which improves interlayer adhesion, as shown by an eightfold increase in fracture energy measured via a T‐peel test on two printed ...

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Hierarchical Reaction‐Induced Phase Separation in Epoxy/Oligomeric Poly(phenylene ether) Blends: Multiscale Structural and Mechanical Heterogeneity

Journal of Polymer Science, EarlyView.
Hierarchical morphology does not always improve toughness. In epoxy/oPPE blends, curing creates oPPE‐rich primary domains containing nanoscale secondary heterogeneity, as revealed by microscopy, X‐ray scattering, and AFM nanomechanics. Fracture observations show that primary domain–matrix interfacial separation limits tensile ductility despite the ...

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

Stem cell–mediated neuroplasticity and psychological recovery in cancer survivors: Mechanisms, evidence, and translational challenges

Precision Medical Sciences, EarlyView.
Cancer therapies can trigger neuroinflammation and disrupted neuroplasticity, contributing to cognitive impairment and psychological distress in survivors. Stem cells (NSCs/MSCs) and their extracellular vesicles may restore neural niches via trophic support, immunomodulation, synaptic remodeling, and vascular repair, but require rigorous safety, dosing,

Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Indoor UAV for Nuclear Investigation: Experimental Qualification and Field Feedback

Journal of Field Robotics, EarlyView.
ABSTRACT Indoor Unmanned Aerial Vehicles (UAVs) have recently gained interest for inspection and investigation tasks in hazardous environments. In the nuclear field, indoor UAVs offer promising capabilities to reduce workers' exposure to ionizing radiation while accessing confined or elevated areas.
