Total X‐Ray Illumination for Absolute Quantification of Crystalline Phases and Amorphous Content in PVDF and P(VDF‐TrFE)

Macromolecular Materials and Engineering, EarlyView.
A rigorous method, Total Illumination by X‐rays (TIX), is presented to quantify crystalline and amorphous phases in organic materials. Mitigating challenges such as low microabsorption and high amorphous content, an improved, general framework is established, applicable to polymers, MOFs, biological materials, etc.

Strain‐Induced Density Fluctuations in Glassy Polymers

Macromolecular Rapid Communications, EarlyView.
Strain deformation induces the density fluctuations in glassy polymers, resulting in shear‐thinning behavior. ABSTRACT Deformation of glassy polymers induces plastic flow as a result of mechanical instability, ultimately leading to cavitation and fracture of the liquid. Thus, understanding the origin of such mechanical instability is crucial.

Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

Nano Select, EarlyView.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm

Structural and Dynamic Origins of Payne Effect Reduction by Steric Stabilization in Silica Reinforced Poly(butadiene) Nanocomposites

Polymer Composites, EarlyView.
Steric stabilisation of silica nanoparticles suppresses the Payne effect in poly(butadiene) nanocomposites and enables the thickness of the glassy layer to be quantified with QENS experiments. ABSTRACT Silica nanoparticles in polybutadiene nanocomposites cause significantly hindered polymer dynamics in the form of a glassy layer, which can extend more ...

Testing 3D Printed Carbon Fiber Durability for Next‐Gen Fusion Reactors via Proton Irradiation

Polymer Composites, EarlyView.
Schematic of proton irradiation effects on carbon fiber samples evaluated via nanoindentation and Raman spectroscopy. ABSTRACT Carbon fiber‐reinforced composites are promising candidates for plasma‐facing components (PFCs) in next‐generation fusion reactors due to their high strength‐to‐weight ratio, thermal stability, and radiation resistance. However,
