In this study, we use COMSOL Multiphysics® to improve protein separations by the analytical technique asymmetrical flow field-flow fractionation (AF4). AF4 is a very mild separation technique where separation of macromolecules or nanoparticles takes place along a ribbon-like channel that ... En savoir plus

Current trends of research aims at the reduction of conventional fossil fuel consumption so as to mitigate anthropogenic global warming and thus to combat with the climate change. This can be done by shifting to more efficient, alternate, non-conventional and environmental friendly ... En savoir plus

Nano and pico-litre sessile droplet are of large interest in many areas including pharmaceutical and biomedical applications. In particularly it can be used for drug delivery, protein testing or to control nucleation in confined environment. Industrial and research use of such methods ... En savoir plus

Reactive transport models (RTM) that couple physical and chemical processes are commonly used to solve a large variety of problems in the environmental industry. There are a series of codes designed to solve this kind of problems. However, their use requires typically much effort due to ... En savoir plus

Mechanics of living cells and tissues play a central role in many phenomena, from tissue shape formation (morphogenesis) to migration of cells within tissues. One prominent example is the epithelia – a sheet of cells tightly attached to one another. It provides a physical barrier to ... En savoir plus

COMSOL Multiphysics® was used to evaluate the performance of a woofer coupled to an automotive door. Two uses cases were considered: rigid and non-rigid door structures. Using the Structural Mechanics Module, the speaker membrane displacement was computed for both cases from 20Hz to 500 ... En savoir plus

In the past two decades, highly porous nanostructured materials have been investigated and used for a large variety of applications, such as catalysis, energy conversion/storage, optics, sensing and more. Nanoporous gold (npAu) is one of such materials which have shown great potential as ... En savoir plus

The ever-growing complexity of samples which need to be processed in e.g., environmental and biomedical/biochemical research, demand higher efficiencies of analytical techniques. Liquid chromatography (LC), mass spectrometry, among others, are analytical techniques that revolutionized ... En savoir plus

The calculation of additional losses in induction machines is a challenging task. In skewed motors, a part of these losses is connected to the phenomena of inter-bar currents. Inter-bar currents flow between adjacent bars through the rotor lamination. Since they are aligned perpendicular ... En savoir plus

Nondestructive Testing (NDT) refers to a wide group of methods used in industry to evaluate the properties of a material, component or system without causing damage. These include radiography, ultrasound, electromagnetic and visual, among others. Eddy-current testing (ECT) is one such ... En savoir plus
