Flow‐Induced Vascular Remodeling on‐Chip: Implications for Anti‐VEGF Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Flow‐induced vascular remodeling plays a critical role in network stabilization and function. Using a vasculature‐on‐chip system, this study reveals how physiological VEGF levels and flow affect vascular remodeling and provides insights into tumor vessel normalization.

Stress and Vascular Responses: Atheroprotective Effect of Laminar Fluid Shear Stress in Endothelial Cells: Possible Role of Mitogen-Activated Protein Kinases

open access: yesJournal of Pharmacological Sciences, 2003
Atherosclerosis preferentially occurs in areas of turbulent blood flow and low fluid shear stress, whereas laminar blood flow and high shear stress are atheroprotective.

Performance of high-speed hydrodynamic sliding bearings with lubricating oils combining laminar and turbulent flows

open access: yesAdvances in Mechanical Engineering, 2020
High-speed hydrodynamic sliding bearings use lubricating oil that can have laminar and turbulent flow states, yet turbulent states remain relatively unstudied.

Separation and Surface Nuclei Effects in a Cavitation Susceptibility Meter [PDF]

open access: yes, 1991
This work is concerned with the effects of flow separation and surface nuclei on the operation of a fixed geometry Cavitation Susceptibility Meter (CSM) with laminar flow. Cavitation is induced under controlled conditions at the throat of a glass venturi

Laminar-Turbulent Patterning in Transitional Flows [PDF]

open access: yesEntropy, 2017
Wall-bounded flows experience a transition to turbulence characterized by the coexistence of laminar and turbulent domains in some range of Reynolds number R, the natural control parameter. This transitional regime takes place between an upper threshold R t above which turbulence is uniform (featureless) and a lower threshold R g below ...

Vat Photopolymerization of High Molecular Weight Polymer Latexes with Pseudothermoplastic Properties for Recyclability

open access: yesAdvanced Functional Materials, EarlyView.
A photocurable latex system enables high‐resolution vat photopolymerization of water‐dispersed thermoplastics, yielding pseudothermoplastic materials with recyclability. The formulation permits precise control over mechanical properties and supports reprocessing through conventional and extrusion‐based methods. Compatibility with two‐photon 3D printing

Effects of Velocity Profiles on Measuring Accuracy of Transit-Time Ultrasonic Flowmeter

open access: yesApplied Sciences, 2019
Ultrasonic wave carries the information for flowing velocity when it is propagating in flowing fluids. Flowrate can be obtained by measuring the propagation time of ultrasonic wave. The principle of transit-time ultrasonic flowmeters used today was based

On Reflection of Shock Waves from Boundary Layers [PDF]

open access: yes, 1952
Measurements of the reflection characteristics of shock waves from a flat surface with a laminar and turbulent boundary layer are presented. The investigations were carried out at Mach numbers from about 1.3 to 1.5 and a Reynolds number of 0.9 x 10^4.

Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

DIAGNOSIS OF STEADY-STATE CHARACTERISTICS IN LAMINAR FLOW OF FLUIDS

open access: yesRudarsko-geološko-naftni Zbornik
Laminar flow of fluids is one of the most common forms of motion in oilfield practice. In such a flow regime of fluid, the determination of velocity-flow rate performance which takes into account the rheological properties of the fluid is of great ...
