Introduction: Lithium-ion batteries are widely used as power sources for portable electronic devices (laptop, phones, and players) and electric cars due to their high energy density. New applications, such as Formula E, require also a huge power capability that the iron-phosphate-based positive electrode is able to provide. Indeed, a recent publication  shows that, at the particle level (20 ...

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 of samples (conductivity, permittivity, charge, etc.). These techniques scan the surface of a sample ...

Nano patterning for chip manufacturing has reached its limitation with 193i lithography standard process. Directed Self Assembly (DSA) of Block Co-Polymers (BCP) is envisaged as an alternative complementary technique that can reduce critical dimension and pitch with high throughput and limited cost . For contact layers that require patterning of cylinders with diameter of tens nanometers, DSA ...

The in-gas-jet laser ionization and spectroscopy method (Figure 1) that has been developed at KU Leuven allows to produce and to perform laser spectroscopy of short-lived radioactive isotopes created in different types of nuclear reactions [1,2]. To realize the advantages of in-gas-jet ionization, the parameters of the gas cell (in which the isotopes under investigation should be efficiently ...

At present, no 3D transient magnetic and electric fields formulation with strong eddy currents and high electric fields is available in the physical applications with COMSOL Multiphysics® software. However, some industrial products need such a tool, as it is the case for induction coils of pulsed magnetic technologies. The principle is to induce a force thanks to strong eddy currents induced by ...

A Laser-welded blank (LWB) consists of steels of different thicknesses and/or grades welded together to produce a single blank prior to the forming process. LWB are mostly used in the automotive field where the high productivity of the laser welding process is an advantage. Numerical modeling of the welding process could be a way to optimize the energy input and the quality of LWB, by taking ...

INTRODUCTION The purpose of this work is to verify the effect of Multigrid method on the CPU time for the resolution of the heat transfer model, based on the Finite Element Method (FEM), in order to simulate the laser surface remelting (LSR) of the Al–1.5 wt.% Fe alloy. To accelerate the convergence of Single grid methods, Multigrid method (MG) was employed in order to reduce the CPU time. In ...

Recently, increasing availability of natural gas, due to the shale gas, raises the attention to the conversion of methane. Methanol-to-Hydrocarbons reaction (MTH) plays an important role in this route where methanol synthesized through syngas is converted into hydrocarbons, such as Gasoline. In this study heat and mass transfer for MTH reaction over ZSM-5 as catalyst for an specific microreactor ...
