Water: How does it influence the CaCO3 formation?

Esther Amstad, Huachuan Du

ature produces biomineral‐based materials with a fascinating set of properties using only a limited number of elements. This set of properties is obtained by closely controlling the structure and local composition of the biominerals. We are far from obtain ...

Development of a Monolithic Fiber-Based Electric Field Sensor

Mahdi Tamizifar

This project has been done on the development of a monolithic fiber-based electric field sensor, with a focus on establishing a reliable, cost-effective, and scalable production cycle to be implemented initially at a pilot and consequently at an industrial ...

Electric Field Effects in the Skyrmion Lattice Hosting Magnet Cu2OSeO3

Saumya Shivam

Magnetic skyrmions have garnered much attention in recent years because of their non trivial topology and potential to be used in next generation memory devices. They may exist individually or as a lattice of skyrmions(SkL). A number of investigations have ...

Lorentz Force from a Current-Carrying Wire on a Charge in Motion under the Assumption of Neutrality in the Symmetrical Frame of Reference

Marcos Rubinstein, Antonio Sunjerga

It is commonly assumed that a wire conducting an electric current is neutral in the laboratory frame of reference (the rest frame of the lattice of positive ions). Some authors consider that the wire is neutral only in a symmetrical frame of reference, in ...

The surprising influence of continuous alternating electric current on recrystallization behaviour of a cold-rolled Aluminium alloy

Roland Logé, Cyril Cayron, Ke Huang

Pronounced acceleration of recrystallization in cold worked metals is generally observed during annealing with additional high density electric current pulses. In this work, continuous alternating current of low density was applied to heat cold-rolled samp ...

Statistics of Test Results for the ITER Nb3Sn and NbTi Conductors in the SULTAN Facility

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Rainer Wesche

The series production of Nb3Sn and NbTi cable-inconduit conductors (CICC) for the winding of various coils in the International Thermonuclear Experimental Reactor (ITER) magnet system is being completed in 2015. The tests of the ITER conductor samples are ...

Comb Drive Designs With Minimized Levitation

Matthias Imboden

This paper presents two capacitive comb drive designs for electrostatic actuation of MEMS with the aim to eliminate the levitation effect often observed in such systems. By placing a shield over the comb drive fingers, it is possible to balance the electri ...

Ieee-Inst Electrical Electronics Engineers Inc2016

In this paper the realization and optimization of two coreless open-loop bus bar current transducers based on a Hall effect sensor are presented. Two types of bus bar are evaluated: flat rectangular and rectangular with a restrictive region in the middle. ...

Iop Publishing Ltd2016

We provide a mathematical analysis and a numerical framework for Lorentz force electrical conductivity imaging. Ultrasonic vibration of a tissue in the presence of a static magnetic field induces an electrical current by the Lorentz force. This current can ...

Elsevier2015

The principle achievement of this contribution is to develop and to describe a rapid DC component elimination strategy for AC currents in the frequency converter, simply by selecting transient period. To avoid DC component on the line current, it’s known t ...
