Perovskite solar cells (PSCs) are a promising photovoltaic technology but their performance remains limited by incomplete absorption of incident photons, primarily due to reflection at the transparent front electrode [1]. To address this issue, interface engineering with graphene-based ... Mehr lesen
INTRODUCTION The global energy infrastructure is comprised of a variety of power magnetic devices (PMDs) which include motors, generators, transformers, inductors, actuators, relays, etc. In the field of power engineering, and particularly in the design of PMDs, modern advances are ... Mehr lesen
Recent retina implants have been shown to form monochromatic vision with prosthetic visual acuity of 20/438, dependent on the individual pixel size of 100 microns [1]. It is still far from meaningful image formation. Overall, the key challenge in retinal stimulation is the unresolved ... Mehr lesen
Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... Mehr lesen
Induction heating (IH) [1] is a good candidate for decarbonization of chemical processes: energy savings, process intensification and production costs reduction [2-5]. Heat can be generated directly into the reactor at the surface in contact with the gas flux passing through a specific ... Mehr lesen
In the frame of an ESA project, CSEM in collaboration with other partners has developed an innovative Attitude Orbit Control System concept that relies on a Reaction Sphere. We propose to use one unique magnetic bearing Reaction Sphere whose spin axis and angular velocity can be ... Mehr lesen
In this paper the propagation of a plane wave in a large lossy medium is presented. The investigated geometry consists in a wedgeshaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar ... Mehr lesen
The article deals with the magnetically-supported high-power full-penetration laser beam welding of aluminum. A stationary simulation was conducted accounting for the effects of natural convection, Marangoni convection and solid-liquid phase transition as well as an electromagnetic ... Mehr lesen
Electromagnetic forming (EMF) is a typical high speed forming process using the energy density of a pulsed magnetic field to form workpieces made of metals with high electrical conductivity like e.g. aluminium. This forming process can be very advantageous as compared to conventional ... Mehr lesen
Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper ... Mehr lesen
