Multi-layer ferroelectrets consisting of fluoroethylenepropylene (FEP) copolymer and open-porous expanded polytetrafluoroethylene (ePTFE) films exhibit stable internal electret charges, high piezoelectric coefficients and heat resistance, making them promising candidates for wearable sensors or nanogenerators in body-area networks. Here,...

In contrast to molecular-dipole polymers, such as PVDF, ferroelectrets are a new class of flexible spatially heterogeneous piezoelectric polymers with closed or open voids that act as deformable macro-dipoles after charging. With a spectrum of manufacturing processes being developed to engineer the heterogeneous structures, ferroelectrets are...

An estuary forms the transition between the  ocean/sea and a river and within its boundaries  fresh and salt water mix. Fresh water intake  points may be located within the reach of salt  intrusion. In order to justify political and  managerial decisions it is thus necessary to  understand and be able to predict...

The paper presents the experimental technology required to measure the performance of moderate temperature heat pipes. The heat pipe manufacturing process is described also. The hydrodynamic characteristics of the porous structure inside the heat pipe envelope were examined using a specially developed test rig (described), based upon a...

In this paper the CAD system DESTIP is described. DESTIP is developed at the NLR for designing compression panels in wing box structures. Application of the system yields optimal panels in the sense that they meet all the requirements imposed by the designer and have minimum weight per unit width. Weight reductions ranging from 0 to 10% have...

The thermal conductivity of a honeycomb sandwich panel was mesisured in the three characteristic directions. The measurements were carried out in the NLR space simulation chamber. The results are in good agreement with values calculated for a simplified model.
