Finite element analysis provides new insights into the electrical behavior of conducting adhesives. We show that at a contact between a spherical conducting particle and a flat conducting substrate the current distribution is non-uniform: the current is concentrated at the periphery of ...

Particle-particle interactions are usually neglected when considering the behaviour of magnetic particle's so called magnetic beads in e.g. a microfluidic device. However, if the particle density exceeds a critical limit, this assumption might not lead to proper results anymore. In this ... Per saperne di più
Penning-trap mass spectrometers are the tools of choice for mass-ratio measurements of two different single ions with highest precision. The investigated ions are stored consecutively in a combination of an electric quadrupole potential and a homogeneous magnetic field at ultra-high ... Per saperne di più
High-resolution imaging is useful in oil and gas exploration to identify producing fractures that can be in the millimeter thickness range. In principle, high-resolution imaging maybe achieved using “current injection” to measure the electrical conductivity of the formation. Two current ... Per saperne di più
In this paper we present a new model for computing the current density and field distributions in superconductors by means of a periodic space-time formulation for finite elements (FE). By considering a space dimension as time, we can use a static model to solve a time dependent problem. ... Per saperne di più
This paper describes the design of a normally closed, electrodynamic microvalve. Magnetic forces between a permanent magnet in the valve cover and a soft magnet in the valve seat hold the valve closed. The combination of electrodynamic actuation and a mechanical restoring spring are ... Per saperne di più
Electrical scanning probe microscopy (SPM) techniques, such as electrostatic force microscopy, nanoscale impedance microscopy or scanning near field microwave microscopy, are a relatively new branch of microscopy techniques that can generate images of the nanoscale electrical properties ...

Additive Manufacturing is revolutionizing the industrial sector for complex and individualized metallic components. The most limiting factor of the widely established laser beam melting technology is the scan velocity due to inertia of the mirrors [1]. In electron beam melting (EBM), ... Per saperne di più
Charged particle beam manipulation requires magnetic dipoles for steering and quadrupoles for focusing. Conventional magnets are currently used leading to very large and heavy systems. Miniaturization of the optic magnets would enable the development of more affordable systems and ... Per saperne di più
Parametric finite element simulations were performed to study the effect of film thickness, and electrode size on the different impedance parameters for insulating thin films deposited on a conductive substrate. COMSOL Multiphysics® was used to solve the quasi-static form of Maxwell’s ... Per saperne di più
