We present a procedure to obtain reliable EM responses for a SIW interconnect with microstrip line transitions. The procedure focuses on two COMSOL® configuration settings: meshing size and simulation bounding box. Once both are properly configured, the implemented structure is tested by ... Read More

Biosensors based on silicon nanowires are of great interest for ultrasensitive biomolecular recognition of disease specific markers for early stage diagnosis [1]. However, there are limitations on the performance of these nanosensors in solutions at high ionic strength. This is because ... Read More

We simulated the diffusion of calcium ions through a nanopore created in the cell membrane by electroporation, in presence and absence of the external electric field responsible of the membrane permeabilization. First we solved the set of coupled differential equations that describe the ... Read More

The adoption of micro- and nanostructured electrodes is a promising technique to improve the performance of Li-ion battery, which increases the electrode surface area and improves the efficiency of ion exchange between the electrode and electrolyte. This performance improvement is ... Read More

The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... Read More

This work investigates the frequency-dependent electrothermal behaviors of freestanding doped-silicon heated microcantilever probes operating under the periodic (ac) Joule heating. The transient heat conduction equation for each component (i.e., the low-doped heater region, the high ... Read More

AC electrothermal (ACET) micropumps are based on the temperature gradient caused by Joule heating or an external heat source in the bulk of an electrolyte. In this paper, a 2D simulation was performed to study the effect of substrate thickness and material (glass and silicon) for an ACET ... Read More

We have created and optimized a multiphysics model in COMSOL Multiphysics® software that studies sensitivity to ectopeptidase rates in the rat hippocampus. Ectopeptidases are membrane-bound enzymes whose catalytic domains face the extracellular space (ECS) (Figure 1). They have ... Read More

The study of the effects of magnetic field stimulation in biological systems require devices capable of generating homogenous magnetic fields and further guarantee a controlled and repeatable exposure to different samples involved in the experiment [1]. This work presents analysis and ... Read More

Although cardiac arrest may be statistically insignificant event financial and more important emotional costs in such cases are quite devastating. In this paper we study the effects of multiple grounding pads. Namely, we believe that by placing multiple pads in the lower abdominal part ... Read More
