Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

A Novel Sprayable Fibrinogen/Glycosaminoglycans/Collagen‐Based Bioink for Skin Wound Healing Applied by a Handheld Dual‐Head Airbrush

Advanced Healthcare Materials, EarlyView.
A dual‐head airbrush‐based spraying device, combined with a fibrinogen bioink enriched with glycosaminoglycans and collagen, enables the delivery of biomaterials and cells to promote wound healing. This system demonstrates effective skin regeneration in vitro and in vivo, with comparable results to autografts.

Mathematical Analysis of Casson Fluid Model for Blood Rheology in Stenosed Narrow Arteries

Journal of Applied Mathematics, 2013
The flow of blood through a narrow artery with bell-shaped stenosis is investigated, treating blood as Casson fluid. Present results are compared with the results of the Herschel-Bulkley fluid model obtained by Misra and Shit (2006) for the same geometry.

A Deployable 4D Printed, Mucoadhesive and Magnetically Guided Patch for Local Therapy of Gastric Cancer

Advanced Healthcare Materials, EarlyView.
A new perspective for treatment of gastric cancer is proposed utilizing 4D printing to develop shape morphing, deployable, and magnetically guided local drug releasing patches. The deployed patches are envisioned to adhere at the tumor site to locally deliver high drug amounts.

A Patient‐Specific 3D Printed Carotid Artery Model Integrating Vascular Structure, Flow, and Endothelium Responses

Advanced Healthcare Materials, EarlyView.
This study introduces the first miniaturized, patient‐specific carotid artery model created via 3D printing using GelMA with embedded vascular cells. Combining CFD, PIV, and flow perfusion, the model replicates anatomically dependent hemodynamics and cellular responses.

THE EFFECTS OF BLOOD REHEOLOGICAL ON THE FLOW THROUGH AN AXISYMMETRIC ARTERIAL STENOSIS

Journal of Engineering, 2011
The prediction of the blood flow through an axisymmetric arterial stenosis is one of the most important aspects to be considered during the Atherosclrosis.

A continuum approach applied to a strongly confined Lennard-Jones fluid [PDF]

, 2010
Results from molecular dynamics simulations are analyzed with a continuum approach. It is shown that for strongly confined fluids the Navier-Stokes equations for incompressible, Newtonian fluids are not applicable over the whole channel.

Theorems on shear-free perfect fluids with their Newtonian analogues

, 1997
In this paper we provide fully covariant proofs of some theorems on shear-free perfect fluids. In particular, we explicitly show that any shear-free perfect fluid with the acceleration proportional to the vorticity vector (including the simpler case of ...
