Impact of Fiber Orientation in Electrospun PLA Scaffolds on Fluid Dynamics in a Custom Microfluidic Device

open access: yesAdvanced Healthcare Materials, EarlyView.
Fiber orientation in electrospun scaffolds affects permeability and fluid dynamics in microfluidic devices. Combining experimental data with computational fluid dynamic simulations, we show that aligned fibers enhance flow uniformity, reduce pressure and shear stress variability.

Fluid Shear‐Controlled Pro/Anti‐Inflammatory Osteomodulatory Construct for Drug‐Free Immune Activation Through Cationic Ion Channel Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
A 3D‐printed PCL scaffold coated with Arginine was laminated with electrospun polyvinyl alcohol (PVA) nanofibers containing cationic cellulose nanocrystals (PVA@cCNC). This created nanoisland‐like regions of aligned and random cCNC‐rich fibers. The composite scaffold, under fluid shear stimulation, modulated macrophage polarization from M1 to M2 ...

Chronogroup via Quantum Field Theory F: Algebraic-Topological Unification in Gauge Theory and Holographic Duality

open access: yes
 Abstract This paper proposes an algebra-topology unified framework based on Chronogroup to address non-perturbative challenges in gauge theory and quantum gravity. By constructing the time-varying group law (∗t) and spectral temporal cohomology (Hk t(G,E)), we prove: 1. Isomorphism between first-level cohomology H1&
