On the durability of surgical masks after simulated handling and wear

Jian Wang, Véronique Michaud, Baris Çaglar, Vincent Marc Varanges, Yann Albert Gérard Lebaupin

After the spread of COVID-19, surgical masks became highly recommended to the public. They tend to be handled and used multiple times, which may impact their performance. To evaluate this risk, surgical masks of Type IIR were submitted to four simulated tr ...

Torque Computation With the Isogeometric Mortar Method for the Simulation of Electric Machines

Rafael Vazquez Hernandez, Bernard Kapidani

In this work, isogeometric mortaring is used for the simulation of a six-pole permanent magnet synchronous machine. Isogeometric mortaring is especially well suited for the efficient computation of rotating electric machines, as it allows for an exact geom ...

Experimental Investigation of a Small-Scale Organic Rankine Cycle Turbo-Generator Supported on Gas-Lubricated Bearings

Jürg Alexander Schiffmann, Kévin Rosset

Waste heat recovery (WHR) is expected to contribute to reducing CO2 emissions from trucks. Organic Rankine cycle (ORC) systems show the highest potential for this application, but still lack efficient small-scale expansion devices, in practice. A novel tur ...

Novel Optimized Shape and Topology for Slotless Windings in BLDC Machines

Yves Perriard, Adrien Jean-Michel Thabuis, Douglas Martins Araujo, Guillaume Paul-André Burnand

Slotless windings are commonly used in small size high-speed electrical brushless dc machines. Unlike slotted windings, forced to follow the direction of slots, slotless windings can be freely arranged in the airgap. This represents several opportunities f ...

Simultaneous sample washing and concentration using a “trapping-and-releasing” mechanism of magnetic beads on a microfluidic chip

Martinus Adela Maria Gijs

Simultaneous washing and concentration of functionalized magnetic beads in a complex sample solution was demonstrated by applying a rotational magnetic actuation system to a microfluidic chip under continuous flow conditions. The rotation of periodically a ...

Simultaneous magnetic particles washing and concentration in a microfluidic channel

Martinus Adela Maria Gijs

Purification of magnetic microparticles was demonstrated, with a purification efficiency of (72±14) % at a flow rate of 3 μl/min, in a microfluidic chip using a rotational magnetic system under continuous flow conditions. The rotation of a periodically arr ...

Bead-based single protein micro-array realized through electrostatic self-assembly of carboxylated beads

Martinus Adela Maria Gijs, Abdeljalil Sayah, Venkataragavalu Sivagnanam

We report here a simple method, based on electrostatic self-assembly, for realizing bead-based single protein micro-arrays. We generate positively charged surface micro-patterns on a glass substrate and use them as template for adsorbing negatively-charged ...

High speed micromotor on a three axis active magnetic bearing

Alexis Boletis

High speed rotation of small rotors is needed more and more in many industrial applications. Classical examples are compact devices like scanners, gyroscopes, centrifuge units and so on. The key to achieve high rotating speeds is to have contactless bearin ...
