3D Printable Magnetic Soft Actuators–Ink Formulation, Rheological Characterization, and Hydrogel Actuator Prototypes

open access: yesMacromolecular Materials and Engineering, EarlyView.
Magnetic inks for direct ink writing (DIW), a 3D printing technique, are formulated based on acrylamide, iron oxide, and the rheology modifier laponite. They have shear thinning and thixotropic properties. Prototypes printed by DIW, followed by thermal curing, could be magnetically actuated.

Optimizing Electrospun PVA Fibers with MXene Integration for Biomedical Applications

open access: yesMacromolecular Materials and Engineering, EarlyView.
MXene flakes embedded in PVA electrospun fibers improve mechanical stiffness and electro‐conductive properties, not negatively influencing the in vitro viability of L929 cells. These findings suggest the promising use of MXene‐loaded nanofibers as innovative and highly versatile platforms for tissue engineering and biosensing applications.

Thermo‐Mechanical and Structural Characterization of Isothermally Annealed 3D Printed Pseudo‐Amorphous Polyetherketoneketone (PEKK).

open access: yesMacromolecular Materials and Engineering, EarlyView.
Isothermal annealing of 3D‐printed pseudo‐amorphous PEKK significantly enhances its crystallinity and mechanical properties. Thermal analysis reveals that annealing time and temperature play a critical role, with crystallinity levels reaching up to 27%.

Grape Seed Proanthocyanidins: A Potential Microbiome‐Targeted Intervention for Healthy Aging in Rats

open access: yesMolecular Nutrition &Food Research, EarlyView.
Grape seed proanthocyanidin extract (GSPE) promotes a healthier gut phenotype in aged rats. Aging alters gut microbiota composition, increases inflammation, and compromises intestinal barrier function. This study shows that short‐term GSPE treatment in aged rats partially restores microbial diversity toward a youthful profile, modulates mucus‐related ...
