Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux ... En savoir plus
The nematode Caenorhabditis elegans is a widely adopted model organism for studying various neurobiological processes at the molecular and cellular level in vivo. With a small, flexible, and continuously moving body, the manipulation of C.elegans becomes a challenging task. A lab-on-a ... En savoir plus
Hydrophones are acoustic receivers, which can be used to listen to the sound propagating underwater for the purposes of monitoring marine life, or other sound producing activities in the sea. Commonly used hydrophones are based on piezoelectric transducers. With the introduction of fiber ... En savoir plus
Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared ... En savoir plus
Fuel cells are electrochemical devices which produce electricity from renewable and clean resources, such as hydrogen. Their large-scale exploitation is expected to impact positively our approach to use electric energy in vehicles, buildings and other portable/stationary applications. ... En savoir plus
Determination of Estrogen Receptor [ER] status is a key in detecting cancer pathogenesis at early stage. In our work we discuss Near Infrared Fluorescence [NIRf] Molecule Optical Imaging Diagnostic modality for early detection of breast cancer. A novel target-specific NIRf dye conjugate ...

Water calorimetry is employed to establish a primary reference standard for radiation dosimetry by measuring the temperature rises in a water phantom (a cube of about 30 cm x 30 cm x 30 cm) subjected to a beam of ionizing radiation. We use COMSOL Multiphysics to model the system using ... En savoir plus
Technologies based on micro electro mechanical systems (MEMS) present advantages for rheological applications as they enable the fabrication of smaller sensors with faster response times. In this work we propose fabrication parameters and simulation of a MEMS viscometer. This research ... En savoir plus
The inverse diffusion problems deal with the estimation of many crucial parameters such as the diffusion coefficient, source properties, and boundary conditions. Such algorithms are widely applied in many design problems in different physical, chemical, and biological fields. Recently, ... En savoir plus
The magnetic body forces that act on mono-dispersed magnetic nanoparticles (MNPs) tagged biomolecules in a microfluidic system can be efficiently used in various applications that involve separation and detection including DNA and protein analysis, bio-defense, drug delivery, and ... En savoir plus
