Dijkstra, Hidde (author)We study the flow of supercurrents between two superconducting contacts connected by a 2d layer of graphene. We use a Markov chain Monte Carlo method to find Andreev bound states for circular electron trajectories. Using sample trajectories we estimate the currents as function of the superconducting phase difference between the contacts and the...bachelor thesis 2018

Zhu, L. (author), Guo, J. (author), Gill, E.K.A. (author)In recent years, the increasing need in small satellite solutions triggers the miniaturization of attitude control systems. Reaction spheres were proposed as promising replacements of conventional reaction wheels for their 4π rotations. Since the generated control torques could be about any desired axes, a single reaction sphere is sufficient...journal article 2018

van der Enden, Kian (author)Majorana zero modes have been proposed as building blocks of intrinsically fault-tolerant quantum computers. Currently, externally applied magnetic fields are necessary to induce Majorana zero modes in carefully engineered systems. Topological qubit state readout is realized by parity sensing of Majorana islands. However, fast and high fidelity...master thesis 2017

Jang, S.H. (author), Na, Seon Hong (author), Park, Yong Lae (author)This article presents a soft pneumatic bending actuator using a magnetically assisted bilayer composite composed of silicone polymer and ferromagnetic particles. Bilayer composites were fabricated by mixing ferromagnetic particles to a prepolymer state of silicone in a mold and asymmetrically distributed them by applying a strong non-uniform...journal article 2017

Kirschneck, M. (author)The ever growing population of human beings on earth introduces the challenge of providing affordable, sustainable energy for everyone. Emerging markets, such as China, India or Brazil, quench their thirst for cheap energy by fossil fuels and nuclear power. At the same time researchers from all over the globe warn the public of the advent of a...doctoral thesis 2016

Sales, Morten (author), Plomp, J. (author), Habicht, Klaus (author), Tremsin, Anton (author), Bouwman, W.G. (author), Strobl, Markus (author)Spin-Echo Modulated Small Angle Neutron Scattering (SEMSANS) in Time-of-Flight (ToF) mode has been shown to be a promising technique for measuring (very) small angle neutron scattering (SANS) signals and performing quantitative Dark-Field Imaging (DFI), i.e., SANS with 2D spatial resolution. However, the wavelength dependence of the...journal article 2016

Muralidhar, S.H. (author)The international growing concern for the human exposure to magnetic fields generated by electric power lines has unavoidably led to imposing legal limits. The world health organization sets limits for exposure to magnetic and induced electric fields. Basically, the world health organization references to the guidelines provided by the...master thesis 2015

(author)We investigate the degradation of the magnetic moment of a 300?nm thick FePt film induced by Focused Ion Beam (FIB) milling. A 1??m?×?8??m rod is milled out of a film by a FIB process and is attached to a cantilever by electron beam induced deposition. Its magnetic moment is determined by frequency-shift cantilever magnetometry. We find that the...journal article 2015

Fondse, S.L.J. (author)In a world of improving health care, some diseases are still very hard to diagnose. The most common reasons for this problem is the fact that those diseases are non-symptomatic. To gain better diagnoses of such illnesses long term ExG by using bio-medical implants is a good option. These implants have to be powered by a wireless power link. This...master thesis 2015

Kalter, R. (author), Tummers, M.J. (author), Kenjeres, S. (author), Righolt, B.W. (author), Kleijn, C.R. (author)The influence of electromagnetic forcing on self-sustained oscillations of a jet issuing from a submerged nozzle into a thin vertical cavity (width W much larger than thickness T) has been studied using particle image velocimetry. A permanent Lorentz force is produced by applying an electrical current across the width of the cavity in...journal article 2014

Guillou, F. (author), Brück, E. (author)The inverse magnetocaloric effect taking place at the antiferro-to-ferromagnetic transition of (Co,Fe)MnP phosphides has been characterised by magnetic and direct ?Tad measurements. In Co0.53Fe0.47MnP, entropy change of 1.5?Jkg?1?K?1 and adiabatic temperature change of 0.6?K are found at room temperature for an intermediate field change (?B?=?1...journal article 2013

Jiang, J. (author)The combination of Hall sensors and coils can be a practical solution for obtaining a CMOS-compatible contactless current sensor with high bandwidth. A current sensitivity of 1mV/A is achieved by the Hall sensors, and the coils have a current sensitivity of about 8mV/A?µs-1. The current sensitivity is influenced by the actual die position inside...master thesis 2011

Haverkort, J.W. (author), Kenjere, S. (author)A comprehensive computational model for simulating magnetic drug targeting was developed and extensively tested in a cylindrical geometry. The efficiency for particle capture in a specific magnetic field and geometry was shown to be dependent on a single dimensionless number. The effect of secondary flows, a non-Newtonian viscosity and...conference paper 2009

Kenjeres, S. (author)The paper reports on a comprehensive mathematical model for simulations of blood flow under the presence of strong non-uniform magnetic fields. The model consists of a set of Navier–Stokes equations accounting for the Lorentz and magnetisation forces, and a simplified set of Maxwell’s equations (Biot–Savart/Ampere’s law) for treating the imposed...journal article 2008
