Effects of physical determinants in an unsteady blood flow in a stenosed artery

Songklanakarin Journal of Science and Technology (SJST)
This article presents a mathematical model for the impact of physical determinants in unsteady flow of blood in an artery that has stenosis. Continuity and momentum nonlinear partial differential equations (PDEs) are obtained with consideration that ...

Resolving Heterogeneity of Targeted Lipid Nanoparticles Through Solution‐Based Biophysical Analyses

Advanced Materials, EarlyView.
AF4‐UV‐DLS‐MALS‐SAXS resolves previously inaccessible targeted lipid nanoparticle (tLNP) subpopulations that differ in size, shape, and composition. Correlation of subpopulation‐resolved biophysical properties with in vivo RNA delivery reveals that targeted placental transfection is associated with distinct tLNP subpopulations rather than ensemble ...

Meniscus‐Guided Interfacial Ring‐by‐Ring Assembly for In Situ Fabrication of Tubular Hydrogels

Advanced Materials, EarlyView.
A tubular hydrogel fabrication method leveraging the meniscus effect at the oil‐water interface is presented. UV irradiation across the concave surface of the photocurable hydrogel precursor induces the formation of ring‐like hydrogel structures. Sequential ring‐by‐ring assembly within microchannels enables the construction of arteriole‐scale hydrogel ...

Bioinspired Adaptive Surfaces for Intelligent Liquid Manipulation: Progressing From Passive and Active to Hybrid Strategies

Advanced Materials, EarlyView.
This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...

Numerical analysis of blood flow through stenosed microvessels using a multi-phase model

Heliyon
Blood flow in arterioles have attracted considerable research attention due to their clinical implications. However, the fluid structure interaction between red blood cells and plasma in the blood poses formidable difficulty to the computational efforts.

A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

Advanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...

Evaluating flow modulating treatment response in intracranial aneurysms using black-blood MRI in vitro

Communications Medicine
Background Changes in blood flow after brain aneurysm treatment are linked to treatment success. While 4D flow magnetic resonance imaging (MRI) can measure these changes, it is sensitive to metal artifacts from implants. Black-blood MRI, less affected by
