Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

Macromolecular Rapid Communications, EarlyView.
We measure the optical response of poly[3,4‐ethylenedioxythiophene] thin films through the combination of polarized photon spectroscopies (variable‐angle ellipsometry, UV–mid‐IR reflectance and transmittance) and wide‐angle X‐ray scattering, revealing anisotropic optical response and conductivity and enabling structural modelling of chain and π‐system ...

How Can We Improve the Assessment and Indifferent Outcomes From Pelvic Organ Prolapse Management From Conservative and Surgical Therapies? ICI‐RS 2025

Neurourology and Urodynamics, EarlyView.
ABSTRACT Introduction Pelvic organ prolapse is a common condition and many women seek surgical treatment for prolapse symptoms. However, recurrence of prolapse after surgical treatment is common. A think tank was held at ICI‐RS 2025 to discuss how the assessment and indifferent results from conservative and surgical management can be improved.

Comparing the In‐Plane Shear Behavior of Glass Fiber‐Reinforced and Carbon Fiber‐Reinforced Polymer Laminates With the Same Epoxy Matrix System in ±45° Tensile Tests

Polymer Composites, EarlyView.
Schematic illustration of ±45° tensile testing, including detection of first‐ply failure (FPF) by optical crack detection and acoustic emission monitoring, comparison of FPF values with ASTM D3518 and D3039 criteria, and resulting ply level stress states at FPF for GF‐ and CF‐epoxy laminates.

Wear‐Mode‐Dependent Tribological Performance of Glass Fiber‐Reinforced Epoxy Composites Modified With Graphene Nanoplatelets

Polymer Composites, EarlyView.
Graphical representation of the wear‐mode‐dependent tribological behavior of graphene nanoplatelet (GNP) modified glass fiber‐reinforced epoxy composites, highlighting the distinct mechanisms governing dry sliding wear and solid particle erosion. ABSTRACT Glass fiber‐reinforced epoxy composites are widely used in structural applications where surface ...

How Poly(Ethylene Terephthalate) (PET) From Mechanically and Chemically Recycling Affects the Performance of Monopolymer Blends

Polymer Engineering &Science, EarlyView.
Mechanical recycling process and chemically recycled commercial blend pellets. ABSTRACT From 2030, in line with the new directive issued by the European Union, manufacturers of plastic beverage bottles will have to include at least 30% recycled plastic, calculated as an average for all bottles placed on the market in each Member State. In this context,

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

Journal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Biaxial fatigue loading of notched composites [PDF]

Thin walled, 2.54-cm (1-in.) diameter tubular specimens of T300/934 graphite/epoxy were fabricated and fatigue cycled in combinations of axial, torsional, and internal pressure loading.

Negative Stiffness Induced and Controlled by Constriction

physica status solidi (b), EarlyView.
Structures with negative stiffness can be stabilized by constriction of external displacement. Furthermore, constriction can make a conventional positive stiffness material exhibit negative stiffness, either bidirectional or unidirectional (shown in the figure).

Failure criterion of glass fabric reinforced plastic laminates [PDF]

Failure criteria are derived for several modes of failure (in unaxial tensile or compressive loading, or biaxial combined tensile-compressive loading) in the case of closely woven plain fabric, coarsely-woven plain fabric, or roving glass cloth ...
