Extension of Isoconversional Analysis to Diffusion‐Controlled Epoxy Cure Kinetics: Comparison With Model‐Fitting Approaches

open access: yesPolymer Engineering &Science, EarlyView.
Extending isoconversional analysis of DSC data to diffusion‐controlled regimes captures the rise in apparent activation energy upon vitrification and yields TTT diagrams of RTM6 epoxy resin that remain accurate when diffusion, rather than chemistry, governs the cure rate.

Sustainable PEG‐Based Shape‐Stabilized Phase Change Materials Using Raw Pine Cone as a Low‐Cost Filler and Graphite for Enhanced Thermal Conductivity

open access: yesPolymer Engineering &Science, EarlyView.
Preparation of sustainable PEG‐based ssPCMs using a PC‐based low‐cos filler and G as a thermal enhancer. PEG 6000 is incorporated into the PC/G matrix through mixing to obtain the shape‐stabilized PCM for thermal energy storage applications. ABSTRACT This study investigates the development of a novel shape‐stabilized phase change material (ssPCM ...

Extruder‐based 3D printing of eco‐friendly polymers

open access: yesPolymer International, EarlyView.
Eco‐friendly polymers, such as biodegradable and recycled materials, offer significant potential for the production of high‐quality 3D‐printed components, provided that their properties and characteristics meet the requirements of extruder‐based 3D printing.

Opposite Trends in Glass Transition and Vogel Temperatures in Long‐Chain Branched Poly(l‐Lactic Acid)

open access: yesJournal of Polymer Science, EarlyView.
The glass transition temperature (Tg), as determined by conventional DSC, increases from 326 K to 329 K while the Vogel temperature (Tv) decreases from 271 K to 255 K as the number of branch points per molecule increases from 0 to 3.3. ABSTRACT Poly(l‐lactic acid) (PLLA) is widely used as both a commodity thermoplastic and for engineering applications,

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

open access: yesProteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.

Stratospheric influence on tropical cyclone evolution

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We developed a metric based on moist static energy to detect and quantify the intrusion of stratospheric air into the inner core of tropical cyclones. High‐resolution numerical simulations show that this stratospheric interaction forms warm anomalies (high‐level warm cores) in the upper troposphere.
