Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

This work aims at the modelling of a 5 cm^2 Direct Methanol Fuel Cell (DMFC) with mixed serial/parallel serpentine flow fields in terms of current/voltage behaviour. The geometrical design of the single cell is presented in figure 1. The function principle as well as the electrochemical ... 詳細を見る

Introduction The topology optimization method is becoming increasingly popular as a design tool for multiphysics systems [1,2]. Topology optimization of fluid-thermal systems has been presented for example in [3] for forced convective heat transfer and in [4] for natural convection ... 詳細を見る

Capacitive energy extraction based on double layer expansion (CDLE) is a new method devised for extracting energy from the exchange of fresh and salty water in porous electrodes. First suggested by D. Brogioli, it is enclosed in a group of emergent technologies jointly known as Capmix ... 詳細を見る

Introduction: This study describes a thin and low-cost capacitive pressure sensor in touch mode (TM) for monitoring fluid pressure from 0 to 40kPa in fluidic chambers with Luer fittings for medical applications. TM provides good linearity, large measuring range and large overload ... 詳細を見る

Lithium-sulphur (Li-S) batteries have the potential to surpass the energy storage capability of Li-ion batteries due to their high theoretical gravimetric energy density of 2700 Wh/kg. However, the processes which drive the system behaviour are much more complex than those in a Li-ion ... 詳細を見る

We present computer simulation results for PEM fuel cells using COMSOL Multiphysics® software. We have developed novel PDE equations at NPL from first principles and these are more realistic than models typically used in literature. The theory includes Maxwell-Stephan and Nernst-Planck ... 詳細を見る

INTRODUCTION: Active cooling systems represent a possible solution to the electronics overheating that occurs in downhole tools operating on wireline, a cabling technology used to remotely control the downhole devices during oil and gas well interventions, in high temperature wells (150 ... 詳細を見る
