Novel Sulfur‐Rich Polymers from Inverse Vulcanization as Functional Building Blocks for Photonics

Macromolecular Rapid Communications, EarlyView.
Isopropenyl aromatic comonomers, in particular novel 2,7‐diisopropenylfluorene and 2,8‐diisopropenyldibenzothiophene, synthesized by sustainable, facile, single‐step SMCCR from available brominated substrates are exploited in the Inverse Vulcanization process to obtain functional Sulfur‐rich macromolecular materials.

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 ...

Bending Analysis of Thickness‐ and Shear‐Deformable Materially Imperfect Composite Shells With von Kármán‐Type Geometric Nonlinearities

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Geometrically nonlinear static analysis of materially imperfect composite doubly curved shells is investigated via the generalised differential quadrature method. The effects of both shear and thickness deformation are considered through a thickness‐ and shear‐deformable third‐order theory formulated in curvilinear coordinates, while the ...

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

physica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...

On the Origins of Out‐of‐Plane Auxetic Response in Paper

physica status solidi (b), EarlyView.
Paper can be auxetic! Paper can exhibit a range of out‐of‐plane Poisson's ratio (PR) values. Examining handsheets made from hardwood (HW) and softwood (SW) fibers, of a variety of weights (1, 3, or 5 g) and refining degrees (none, R, or R+), showed that the sign and magnitude of PR can be finely controlled by modifying network parameters.
