Unsteady viscous vortex with flow toward the center [PDF]
Applied Scientific Research, 1966 An analysis was made of a strong unsteady vortex that consists of an annular region, in which the flow is tangential and radial and a core region, in which a uniform axial flow is also present. The effects of end-wall boundary layers, if present and important, were assumed to be eliminated by use of suitably rotating end walls.

Advanced Functional Materials, EarlyView.ABSTRACT Electronic waste has emerged as a major environmental challenge, driven by the massive consumption and a limited lifetime of modern electronic devices, stimulating the development of sustainable electronics. Here, an all‐biomaterial gelatin‐choline‐citric acid ([Ch][CA]) ionogel is developed as an active binder to realize self‐sintered ...

Viscous-Inviscid Interactions in a Boundary-Layer Flow Induced by a Vortex Array [PDF]
Acta Applicandae Mathematicae, 2014 In this paper we investigate the asymptotic validity of boundary layer theory. For a flow induced by a periodic row of point-vortices, we compare Prandtl's solution to Navier-Stokes solutions at different $Re$ numbers. We show how Prandtl's solution develops a finite time separation singularity. On the other hand Navier-Stokes solution is characterized

Advanced Functional Materials, EarlyView.This article details the development of an artery‐on‐chip platform for in vitro arterial disease modeling and therapeutic discovery. It describes the fabrication of a fibrin biomaterial scaffold seeded with iPSC‐derived smooth muscle and endothelial cells, mimicking native artery properties. Two genetic disease models showcase the platform's ability to

Advanced Functional Materials, EarlyView.A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids
Advanced Functional Materials, EarlyView.Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

ON THE MECHANISM OF THE FORMATION OF MAGNETOHYDRODYNAMIC VORTICES IN THE SOLAR PLASMA
Odessa Astronomical Publications, 2016 Based on the magnetohydrodynamic (MHD) equations for an incompressible conductive viscous fluid, the possible mechanism of the formation of giant MHD vortices recently discovered in the solar atmosphere (chromosphere) is analyzed.
