Assessment of Methacrylated Poly(ε‐Caprolactone)/Silanized Hydroxyapatite Composite Resin for High‐Resolution Scaffolds via Vat Photopolymerization 3D Printing

Polymers for Advanced Technologies, Volume 37, Issue 2, February 2026.
ABSTRACT High‐resolution, biocompatible scaffolds are essential for reproducible tissue engineering and remain challenging to fabricate with vat photopolymerization due to cure‐depth control and limited bioactivity of neat polymers. This work investigated the mechanical, surface, and biological properties, as well as the high‐resolution 3D printability,

Thermo‐Electro‐Mechanical Characterization of Thermoset and Thermoplastic Blends for Composite Polymer Electrolytes

Journal of Applied Polymer Science, Volume 143, Issue 1, January 5, 2026.
This study investigates the thermo‐electro‐mechanical properties of thermoplastic/epoxy blends as polymer hosts for composite polymer electrolytes. Blending PEO, PVA, and PVAc with heat‐resistant epoxy via suitable solvents yields films with high ionic conductivity and improved thermo‐mechanical stability, making them promising candidates for use in ...

Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics

Advanced Optical Materials, Volume 14, Issue 4, 27 January 2026.
Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.

Neem oil (Azadirachta indica) as a promising feedstock for biolubricant production: enzymatic synthesis, process optimization, and molecular studies

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 237-252, January/February 2026.
Abstract The fuel industry remains closely tied to oil‐based fuels. This relationship is responsible for increasing greenhouse gas emissions. Biofuels are an alternative to petroleum‐based fuels that could make industrial production lines more sustainable.
