Gecko foots have inspired researchers to develop designs that can help robots to tread vertically oriented surface. These nanobots find many applications as they can perform a lot of operations more efficiently and also lower the cost of such operations. These can be employed in various ... En savoir plus

Introduction: Failure in cable insulation is generally preceded by a degradation phase that may last several years. A significant cause of cable system failures is the breakdown of electrical insulation between the electrodes. The operational stresses that occur in cable insulation which ... En savoir plus

The motion of DNA in crowded environments is a common theme in physics and biology. Examples include gel electrophoresis and the self-interaction of DNA within cells and viral capsids. Here we study the interaction of multiple DNA molecules within a nanopore by tethering the DNA to a ... En savoir plus

ELENA is a small cooler decelerator ring at CERN which will be built to increase substantially the number of usable antiprotons delivered to experiments for studies with antihydrogen and antiprotonic nuclei. COMSOL Multiphysics® software has been used to completely model the ELENA ... En savoir plus

A two-dimensional numerical simulation study has been performed to model an electrohydrodynamic (EHD) micropump. The emphasis of this study was on simulating the effect of the different geometric design parameters on the micropump pressure head and volume flow rate. The simulated design ... En savoir plus

This paper gives an overview of modelling microsensors on geometry and system level. The focus will be on the generation of the multiphysics reduced order system model and the coupling with package and ASIC models. The method is based on modal superposition. This means all the details of ... En savoir plus

This poster studies catalytic micropumps and their ability to induce fluid flow on the microscale. The goal of the study is to design a long-distance, directed convective loop. An array of catalytic micropumps was constructed in the domain, comprised of two distinct catalysts in an ... En savoir plus

In the conference we bring together a community that is scientifically diverse in an event about the use of COMSOL Multiphysics. Oral and poster presentations highlight achievements in multiphysics modeling and simulations using COMSOL. En savoir plus

The tunable capacitor (variable capacitor) is one of the most important and components in filters, Phase shifters, VCO etc. A tunable capacitor can also be built using electro – thermal actuating mechanism. Compared to electro static, tunable capacitors actuated by thermal actuators ... En savoir plus

We studied the optical phonon excitations (LO) of ordered arrays of dot/ rod core-shell CdSe/ CdS nanorods by Raman spectroscopy. Upon deposition on planar substrates the nanorods formed super-lattice structures via side-by side assembly into tracks over some microns of length. COMSOL ... En savoir plus
