The performance of nanoporous hydrogel microplugs with varying surface charge density is described in concentrating charged analytes electrokinetically in a microfluidic device. A neutral hydrogel plug with a mean pore size smaller than the size of charged analytes acts as a simple size-exclusion membrane. The presence of fixed charges on the backbone of a nanoporous hydrogel creates ion-permse...

Phase II of the research developed and tested a pilot scale prototype system and conducted extensive experiments to generate the required data to petition FDA approval of the technology. Data generated during the study enhanced the scientific understanding of this novel process, and provided technical information on the effects of the treatment on inactivation of microbes, enzymes and quality o...

this paper describes the impact of the distance and the size of the corona ring, on the magnitude anddistribution of electrical potential across the polymer insulators. the procedure is based on finiteelement method numerical analysis and stochastic optimization algorithm of differential evolution(de). the optimal selection of corona ring has a significant impact on the control of potential and...

Both a Cu-26 wt % Ag (Fe-free) alloy and Cu-26 wt % Ag-0.1 wt % Fe (Fe-doping) alloy were subjected to different heat treatments. We studied the precipitation kinetics of Ag and Cu, microstructure evolution, magnetization, hardness, strength, and electrical resistivity of the two alloys. Fe addition was incapable of changing the precipitation kinetics of Ag and Cu; however, it decreased the siz...

An attractive alternative treatment for malignant tumors that are refractive to conventional therapies, such as surgery, radiation, and chemotherapy, is electrical-pulse-mediated drug delivery. Electric field distribution of tissue/tumor is important for effective treatment of tissues. This paper deals with the electric field distribution study of a tissue model using MAXWELL 3D Simulator. Our ...

OBJECTIVE The present work proposes a new clinical approach to TTFields therapy of glioblastoma. The approach combines targeted surgical skull removal (craniectomy) with TTFields therapy to enhance the induced electrical field in the underlying tumor tissue. Using computer simulations, we explore the potential of the intervention to improve the clinical efficacy of TTFields therapy of brain can...

We investigated the transport dynamics of individual magnetic domain walls by employing electrical measurements in multiterminal Ga1−xMnxAs microdevices. Domain wall propagation velocities were deduced from time-of-flight planar Hall measurements between multiple electrical probes of our samples. Domain wall motion induced by both magnetic field and electric currents was systematically investig...
