Capillary electrophoresis techniques often involve ion-concentration shock waves in an electrolyte solution, propagating under the effect of an external electric field. These shock waves are characterized by self-sharpening gradients in ion concentrations and electrical conductivity that are collinear with the electric field. The coupling of electric field and fluid motion at the shock interfac...

Energy consumption index is one of the most important criteria for judging about new, and emerging drying technologies. One of such novel and promising alternative of drying process is called electrohydrodynamic (EHD) drying. In this work, a solar energy was used to maintain required energy of EHD drying process. Moreover, response surface methodology (RSM) was used to build a predictive model ...

We proposed a fabrication method of the patterned retarder based on the electrohydrodynamic (EHD) instability. The anisotropic flow of the liquid crystalline polymer (LCP) film enables a net force induced by utilizing the distorted electric field. The patterned retarder based on the EHD instability has simple process with an easy control of the phase retardation and no residual LCP. Therefore, ...

DNA-assisted Förster resonance energy transfer (FRET) between an anthracene-based cyclophane (CP) and mono- and bis-intercalators such as propidium iodide (PI) and ethidium homodimer-1 (EHD), respectively, has been studied using various photophysical and biophysical techniques. The cyclophane and PI exhibited simultaneous binding to DNA at all concentrations studied and showed DNA-assisted FRET...

In this paper, we present the development of a sharp numerical scheme for multiphase electrohydrodynamic (EHD) flows for a high electric Reynolds number regime. The electric potential Poisson equation contains EHD interface boundary conditions, which are implemented using the ghost fluid method (GFM). The GFM is also used to solve the pressure Poisson equation. The methods detailed here are int...

This is the final technical report for NASA Grant No. NGR 11-002-133. The research under this grant consisted of elastohydrodynamic lubrication (ehd) studies and pressure-viscosity studies. Existing equipment was modified to more closely simulate practical ehd conditions. Analyses of ehd and pressure-viscosity data on eleven fluids previously investigated for NASA were also conducted. Near the ...

The novel electrohydrodynamically-assisted electrostatic precipitator (EHD ESP) was developed to suppress particle reentrainment for collection of low resistive diesel particulates. The collection efficiency was compared between the EHD ESP and the conventional ESP using two large diesel engines; 2.3 L and 3.2 L engines. The gas velocity was varied in the range of 1.35 to 7.3 m/s and the load w...

This paper presents the improvements for the performance of a micro-electrohydrodynamic (EHD) pump and the fundamental model theory based on unipolar charge conduction. The EHD pump was fabricated with thin stainless wires which are the diameter of 0.3mm. An electrode pair consisted of one emitter electrode and two collector electrodes. The distance between the emitter and the collector electro...

The present study investigated the anti‑obesity effects of enzyme‑treated Ecklonia cava extract (EEc) in C57BL/6N mice with high‑fat diet (HFD)‑induced obesity. The EEc was separated and purified with the digestive enzymes pectinase (Rapidase X‑Press L) and cellulase (Rohament CL) and its effects on the progression of HFD‑induced obesity were examined over 10 weeks. The mice were divided into 6...

A heterotrophic and autotrophic denitrification (HAD) system shows satisfactory performance for groundwater with nitrate contamination. In this study, an HAD combining solid-phase electrochemical hydrogen (SHD-EHD) was developed the treatment of nitrate-contaminated groundwater, in which polycaprolactone (PCL) used as carbon source to enhance removal prevent secondary pollution (EHD) system. Th...
