Strain‐Induced Density Fluctuations in Glassy Polymers

open access: yesMacromolecular 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.

Engineering Chiroptical Interactions through Integrating Plasmonic Arrays with Cholesteric Nanocellulose. [PDF]

open access: yesAdv Mater
In this study, we demonstrate how the combination of plant‐based cellulose and gold nanoparticle lines produces robust, tunable chiral light control in composite films. The resulting plasmonic cellulose composite exhibits a strong plasmonic CD at the surface lattice resonance, along with an inversion of chiroptical response upon reversing the ...

4D Printable Formulations of Mixed Low and High Molecular Weight Liquid Crystalline Units: A Versatile Route to Functional Soft Actuators

open access: yesMacromolecular Rapid Communications, EarlyView.
This work presents a practical approach for formulating 4D printable inks that incorporates substantial fractions of low molecular weight mesogens. By blending low molecular weight diacrylate or monoacrylate constituents with a high molecular weight main‐chain macromer, the resulting mixture proves suitable for direct ink writing, enabling mechanical ...

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...

Radiation‐Crosslinked PCL–TMPTA Composites via 3D Printing: Structure–Property Relationships and Shape Memory Performance

open access: yesPolymer Engineering &Science, EarlyView.
3D printed shape memory PCL‐TMPTA through high energy gamma radiation modification. ABSTRACT Programmable materials that can reversibly transform between distinct shapes represent a promising technology for applications spanning biomedicine, robotics, and aerospace engineering. Although shape memory polymers offer promising stimuli‐responsive behavior,
