Ferrofluids are stable colloidal suspensions of nanosize magnetic particles in an organic or aqueous medium. Suspending nonmagnetic particles within a ferrofluid has led to numerous new areas of study. The simultaneous action of magnetic and hydrodynamic forces is responsible for the complex behavior of nonmagnetic particles within ferrofluids. As a result of nonzero fluid magnetization, a ...

In this work, backscatter from an elastic sphere was used to validate the computational model against analytical solutions (Faran theory).Agreements between analytical and finite element solutions were found in the scattered far-field over a range of frequencies of interest (10 - 70 MHz). Oscillations of the elastic sphere at various resonance frequencies (peaks in the power spectrum) were also ...

Deep Brain Stimulation (DBS) has been established as an effective treatment for Parkinson's disease and other movement disorders. The stimulation is currently administered using tetrode-macroelectrodes that target the Subthalamic Nucleus (STN). This often leads to side effects which bias the surrounding areas, e.g. the speech centre. Targeting a specific brain region can better be achieved with ...

Radiofrequency Ablation (RFA) represents a valid alternative for treating liver metastases in medically complicated patients. Conventional devices currently operate at 500 kHz, due to good conducting properties of tissues. However, the use of lower frequencies (i.e. 20 kHz) has been recently reported to enhance the treatment effectiveness, due to a more pronounced difference in electrical ...

In this presentation we present our analysis of the PARC Nanocalorimeter. Calorimetry is basically the measuring of heat of chemical reactions or physical changes. Nanocalorimetry is Calorimetry at the Nanometer scale. The PARC Nanocalorimeter is a special type of Calorimeter, it consists of arrays of Nanocalorimeters. The PARC Nanocalorimeter is intended to be used for screening biochemical ...

Atherosclerosis in arteries is caused by the formation of stenosis : fatty depositions, on the artery wall. In current medicine, the practice is to observe the maximum percentage occlusion at any arbitrary cross-section and diagnose the patient on that basis, which might not always present the real picture due to non-uniformity of the stenosis thickness. The present work attempts to simulate the ...

In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on the MNE-tips leads to a situation comparable to the whole-cell mode in classical Patch Clamp. MNE-penetration ...

One of the major applications for dielectrophoresis is the selective trapping and fractionation in lab-on-a-chip devices. Nevertheless, many-particle effects due to high concentrations of biological material around electrodes can cause a rapid decrease of trapping efficiency in dielectrophoretic devices. In this contribution we present a new approach based on a drift-diffusion dynamics to study ...

In this paper, we present a first model carried out with COMSOL Multiphysics to model bread baking, considering heat and mass transfer coupled with the phenomenon of swelling. This model predicts the pressures, temperatures and water contents evolutions in the dough for different energy requests. First results obtained are analyzed according to various physical parameters in order to better ...

The development of atherosclerosis leads to the formation of an atheroma plaque which takes place in the artery. This plaque is composed of two parts: a lipid deposit and a fibrous cap. The fibrous cap covers the lipid deposit and isolates it from the blood flow. The blood flow that circulates in the artery modifies the geometry of the atheroma plaque and can cause dangerous effects, such as a ...
