Designing PLA/PHBV Implants With Degradation Matched to Normal or Inflammatory Tissues

open access: yesJournal of Applied Polymer Science, EarlyView.
PLA/PHBV blends are investigated under simulated normal and pathological conditions. Multivariate statistical analysis decouples the competing effects of water‐uptake‐driven hydrolysis and crystallinity‐imposed barriers. Melt‐state rheological parameters serve as structural probes linking phase morphology to degradation kinetics. A semi‐empirical model

Microwave‐Assisted Alcoholysis of Ethylene–Vinyl Acetate: Phenomenological and Thermal Evolution of EVAOH Terpolymers

open access: yesJournal of Applied Polymer Science, EarlyView.
Microwave‐assisted alcoholysis converts EVA into EVAOH terpolymers, promoting a progressive transition from EVA‐like crystallites to VOH‐rich hydrogen‐bonded crystalline domains. Solvent‐controlled swelling influences conversion kinetics, while thermal analysis reveals a sigmoidal increase in melting temperature that a two‐population crystallization ...

Quantum Heat Current in Terahertz‐Driven Phonon Systems

open access: yesAdvanced Physics Research, EarlyView.
We develop a quantum mechanical description of ultrafast thermodynamics on the example of a laser‐excited phonon mode. We show that the resulting quantum heat current exhibits non‐Markovian dynamics, which can be controlled by the pulse length. ABSTRACT The advent of high‐intensity ultrafast laser pulses has opened new opportunities for controlling and

Moiré Folded Helical States at the Interfaces of Heterostructures

open access: yesAdvanced Physics Research, EarlyView.
This manuscript explores a minimal ladder model of a graphene‐topological‐insulator heterostructure where moiré superlattices modulate Rashba spin‐orbit coupling. The study reveals that SOC lifs spin degeneracy, halves spectral periodicity, and induces “helicity fragmentation” across moiré minibands.

Sintering‐Driven Modulation of Lattice Dynamics, Elastic Behavior, and Dielectric Response in Al–Sn Co‐Doped Zinc Ferrite Nanoparticles

open access: yesAdvanced Physics Research, EarlyView.
Sintering ZnAl0.1Sn0.1Fe1.8O4 nanoparticles at 1200°C optimizes structural lattice dynamics, significantly enhancing both macroscopic elastic stiffness and high‐frequency dielectric response through synergistic Al3+ stabilization and Sn4+‐driven charge transport. ABSTRACT In this work, ZnAl0.1Sn0.1Fe1.8O4 (ZASFO) ferrites were synthesized via a sol–gel
