A Homogenization Model for Soft Magnetic Composites Considering the Effect of Mechanical Stress
Soft Magnetic Composites (SMC) are an alternative to laminated steels for the design of smaller and lighter electromagnetic devices.Such electromagnetic devices might be subjected to significant mechanical stresses that can alter their electromagnetic prop ...
2022Permeability properties of composite reinforcements
Permeability is defined here from the equations of fluid flow through porous media. It represents, for composite reinforcements, a measure for their ease of impregnation by a fluid resin. Modeling of the saturated permeability tensor is presented using a h ...

Magnetic nanoparticle based hyperthermia emerged as a potential tool for treating malignant tumours. The efficiency of the method relies heavily on the knowledge of magnetic properties of the samples; in particular, knowledge of the frequency dependent com ...
2021Measuring compartmental T-2-orientational dependence in human brain white matter using a tiltable RF coil and diffusion-T-2 correlation MRI
The anisotropy of brain white matter microstructure manifests itself in orientational-dependence of various MRI contrasts, and can result in significant quantification biases if ignored. Understanding the origins of this orientation-dependence could enhanc ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2021Challenges and Applications to Operando and In Situ TEM Imaging and Spectroscopic Capabilities in a Cryogenic Temperature Range
Vasiliki Tileli, Martial Duchamp, Reinis Ignatans
In this Account, we describe the challenges and promising applications of transmission electron microscopy (TEM) imaging and spectroscopy at cryogenic temperatures. Our work focuses on two areas of application: the delay of electron-beam-induced degradatio ...
AMER CHEMICAL SOC2021On the effect of a penetrating recirculation region on the bifurcations of the flow past a permeable sphere
François Gallaire, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna, Matteo Ciuti
We study the flow past a permeable sphere modeled using homogenization theory. The flow through the porous medium is described by the Darcy law, in which the permeability quantifies the resistance for the fluid to pass through the microstructure. A slip co ...
AIP Publishing2021Principles and Test Result of Novel Full Passive Magnetic Levitation Motor with Diamagnetic Disk
This paper proposes a novel full passive magnetic levitation motor without active magnetic suspension. It has a magnetic levitation unit and a motor unit. The Halbach array permanent magnets and a pyrolytic graphite (PG) disk realize the full passive magne ...
IEEE2021Scanning SQUID microscopy in a cryogen-free dilution refrigerator
Philip Johannes Walter Moll, Maja Deborah Bachmann
We report a scanning superconducting quantum interference device (SQUID) microscope in a cryogen-free dilution refrigerator with a base temperature at the sample stage of at least 30 mK. The microscope is rigidly mounted to the mixing chamber plate to opti ...
2021Out-of-plane permeability measurement for reinforcement textiles: A benchmark exercise
Véronique Michaud, Damiano Salvatori, Baris Çaglar, Amaël Maximilien Cohades
The out-of-plane permeability of two glass fibre fabrics was measured by 26 institutions using silicone oil as a test fluid. Participants in this study were free to select the test procedure, specimen dimensions and data analysis method, provided that test ...
2021In-series sample methodology for permeability characterization demonstrated on carbon nanotube-grafted alumina textiles
Véronique Michaud, Jacobus Gerardus Rudolph Staal, Baris Çaglar
In-plane permeability of small area (100 × 50 mm) alumina fiber woven fabrics grafted with aligned carbon nanotubes (CNT) was quantified by placing them in series with a glass mat of known permeability during a flow experiment. The methodology was first va ...
