Continuous Production of Highly Tuned Silk/Calcium-Based Composites: Exploring New Pathways for Skin Regeneration

open access: yesMolecules, 2022
Calcium plays an important role in barrier function repair and skin homeostasis. In particular, calcium phosphates (CaPs) are well established materials for biomedical engineering due to their biocompatibility.

Vortex-induced chaotic mixing in wavy channels [PDF]

open access: yes, 2010
Mixing is studied in open-flow channels with conformally mapped wavy-wall profiles, using a point-vortex model in two-dimensional irrotational, incompressible mean flow. Unsteady dynamics of the separation bubble induced by oscillatory motion of point

Synchronization and oscillator death in oscillatory media with stirring [PDF]

open access: yes, 2003
The effect of stirring in an inhomogeneous oscillatory medium is investigated. We show that the stirring rate can control the macroscopic behavior of the system producing collective oscillations (synchronization) or complete quenching of the oscillations

Hydrodynamics and mixing in continuous oscillatory flow reactors—Part II: Characterisation methods [PDF]

open access: yesChemical Engineering and Processing: Process Intensification, 2016
This work presents and exploits quantitative measures to better quantify the performance of oscillatory baffled reactors, being complementary to simple vector plots and shear strain rate fields. Novel performance criteria, including radial and axial fluid stretching and mixing, as well as the shear strain rate history of fluid elements have been ...

Concentration profiles for fine and coarse sediments suspended by waves over ripples: An analytical study with the 1-DV gradient diffusion model [PDF]

open access: yes, 2010
Field and laboratory measurements of suspended sediments over wave ripples show, for time-averaged concentration profiles in semi-log plots, a contrast between upward convex profiles for fine sand and upward concave profiles for coarse sand.

Self-Sustained Oscillatory Flow and Fluid Mixing in a Grooved Channel

open access: yesJournal of the Visualization Society of Japan, 1996
We examined numerically and experimentally self-sustained oscillation and fluid mixing in a grooved channel for steady flow. Oscillatory flow arises from Tollmien-Schlichting waves triggered by a shear layer between channel and groove flows. Vortex dynamics within the groove lead to efficient fluid exchange between both flows.

Intensified processes for FAME production from waste cooking oil: a technological review [PDF]

open access: yes, 2013
This article reviews the intensification of fatty acid methyl esters (FAME) production from waste cooking oil (WCO) using innovative process equipment. In particular, it addresses the intensification of WCO feedstock transformation by transesterification,

On the Effect of Forced-Oscillation Amplitude upon the Flow in a Cubic Cavity Heated Below

open access: yesJournal of Fluid Science and Technology, 2013
The authors numerically investigate the forced-oscillation-frequency responses on flow and thermal characteristics of the thermal convection in a cubic cavity heated from below in the gravitational field, concerning global quantities such as spatially ...
