As the importance of nanoparticles is growing more and more, controlling and understanding the properties of nanoparticles became a focus of research. In this field Meyer at al.  are researching the GMR effect in granular gels to develop magnetoresistive sensors. The GMR in granular gels is simulated to investigate the physical processes in those systems. As soon as the models coincide with ...

Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field . The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs into the cell in a cancer treatment known as electrochemotherapy . In some cases the direct experimental ...

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous limitations interms of performance, stability and size. One way to overcome the limitations is to use thin ...

Cochlear Implants are implantable devices which bypasses the non-functional inner ear and directly stimulates the hearing nerve with electric currents thus enabling deaf people to experience sound again. Implant electrode array design is limited in electrode count, due to their large size in accordance to scala tympani (ST) with restrictions for deeper insertion in ST thus depriving access to ...

Non contact charging of electronic equipment from mobiles to electric vehicle has created immense interest among researchers. There are various groups working on both radiative and non-radiative energy transfer. The idea based on strongly coupled magnetic resonances is of interest because of the increased distance of energy transfer. This technology based on resonant magnetic coupling with the ...

A sharp tip approached perpendicular to a conducting surface at subnanometer distances and biased with a small voltage builds a junction across which electrons can be transferred from the tip apex to the nearest surface atom by direct quantum mechanical tunneling. Such a junction is used e.g. in Scanning Tunneling Microscopy (STM). When the distance d between tip and collector is increased ...

The design of ESS-Bilbao RFQ (RadioFrequency Quadrupole) linear accelerator cavity using COMSOL Multiphysics is presented. The work includes geometry definition, electrostatics, electromagnetic and thermomechanical coupled simulations. The main part of the work corresponds to the electromagnetic design. Geometry construction and meshing is very challenging, involving large models (3 m long) with ...

An electrostatic headphone includes many interrelated design elements that affect the frequency response of the headphone and the users listening experience. Xi Engineering Consultants (XI) partnered with Warwick Audio Technologies (WAT) to investigate the complex behavior of one-side electrostatic speakers. Xi developed a GUI that helped WAT engineers optimize their speaker using virtual tools ...

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 potentially portable devices. The Advanced Magnet Lab, Inc. has developed a revolutionary magnet topology and ...
