A Higher-Order Approach to Fluid-Particle Coupling in Microscale Polymer Flows
Flows containing long-chain polymers are viscoelastic on macroscopic length scales, but in microscale and nanoscale flows hybrid fluid-particle approaches are more suitable. Such an approach would enable more complex predictive modeling, including polymer-wall interactions like [...]
Multiscale Design of a Laser Actuated Micro Bubble Array Acoustic-Fluidic Microdevice for Bioanalytical and Drug Delivery Applications
Next generation fluidic micro-nano devices will require precise control of force fields within a device and their interaction with a biological sample. Current force field designs use mechanical structures such as cantilevers, optical fields e.g. [...]
A lattice Boltzmann study of the non-Newtonian blood flow in stented aneurysm
The treatment of cerebral aneurysms with a minimally invasive porous stent has recently been proposed to prevent rupture and favor coagulation mechanism inside the aneurysm. But, an irregularly shaped and wide-necked aneurysm makes current stent [...]
Viscosity measurements of PEO solutions by AFM with long nanowires
We recently demonstrated that long metal nanoneedles grown on atomic force microscope (AFM) probes can give very clear measurements of the surface tension, evaporation rate and viscosity of simple liquids. However, in the case of [...]
Understanding Conduction Mechanisms in Nano-Structures
Gehman Jr V.H., Long K.J., Santiago F., Boulais K.A., Rayms-Keller A.N., Naval Surface Warfare Center, Dahlgren Division, US
Many technologies require the understanding of conduction and electrical transport mechanisms through nanostructures. Previous research has revealed unusual and enhanced conduction properties in pores whose width is significantly less than 1 m over a range [...]
Ceramic Microarrays for Aggressive Environments
Atre S.V., Wu C., Simmons K.L., Laddha S., Jain K., Lee S., Park S-J, German R.M., Oregon Nanoscience & Microtechnologies Institute, US
The effect of particle characteristics and polymer rheology on the fabrication of sintered ceramic microarrays using powder injection modling is examined. The impact of material composition on microfeature resolution and defect avoidance during processing was [...]
Direct Current Dielectrophoretic Characterization of Erythrocytes: Positive ABO blood types
This work adapts DC-DEP to a medical diagnostic application of sorting blood cells. Initial efforts focus on achieving separation and collection of red blood cells based on their positive ABO blood types. A significant separation [...]
Size Effect on Nano-Droplet Spreading on Solid Surface
In this paper MD simulation has been performed to study the behavior of nano-sized non-polar argon droplets spreading on a solid surface. Three different sizes of the nano-droplet have been examined with the diameters of [...]
