Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms

Advanced Materials Technologies, EarlyView.
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

Advanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Spacer‐Less Substrate‐Integrated Metasurface for Near‐Unity Terahertz Absorption

Advanced Optical Materials, EarlyView.
ABSTRACT Although conventional metal‐insulator‐metal (MIM) terahertz (THz) absorbers can provide near‐unity absorption, their multilayer stacks inevitably introduce additional thickness, mass, and residual stress, which limit their compatibility with THz thermal sensing platforms.

Plasmon‐Induced Optothermal Manipulation of Colloidal Particles and Biological Entities Resilient to Saline Environments

Advanced Optical Materials, EarlyView.
The particle with high surface hydrophilicity exhibits strong thermophoretic attraction, as its dense hydration layer enhances the role of interfacial water molecules in determining thermophoretic mobility over other ionic effects. This finding elucidates the mechanism underlying the robust thermophoretic accumulation of Escherichia coli in high ...

Single‐Layer Cholesteric Liquid Crystal Polymer Films With Visible Broadband Reflection

Advanced Optical Materials, EarlyView.
A single‐layer spin‐coated cholesteric liquid crystal polymer film exhibiting broadband reflection across the visible spectrum is demonstrated. By controlling photopolymerization‐induced pitch‐gradient formation, the film achieves low‐scattering broadband reflection, circular polarization selectivity, and compatibility with photolithographic patterning
