Morphological Implications of the Interphase; Linking Crystalline and Amorphous Regions in Semi-Crystalline Polymers

Rastogi S., Terry A.E., Eindhoven University of Technology, NL

In semi-crystalline polymers, a range of morphologies can be obtained in which a chain may traverse the amorphous region between the crystals or fold back into the crystals leading to adjacent or non-adjacent re-entry, depending [...]

Efficient Generation of Reduced-Order Circuit and Device Models for Wide Frequency Applications

Mijalkovic S., Wu H.C., Delft University of Technology, NL

An attractive approach to enjoy the accuracy of calibrated physical device models in the circuit design, without computational burdens is the reduced-order modeling (ROM). ROM aims at capturing the most important features of the detailed [...]

Conductive Carbon-Nanotube/Polymer Composites: Spectroscopic Monitoring of the Exfoliation Process in Water and the Crucial Role of Wetting

Grossiord N., Loos J., Meuldijk J., Regev O., Miltner H.E., Van Mele B., Koning C.E., Eindhoven University of Technology, NL

For the preparation of conductive polystyrene/SWNT nanocomposites, a recently developed, versatile, latex-based technology is applied. A low molar mass PS fraction, probably acting as a wetting agent for the SWNTs, seems to be required for [...]

Dispersion and rheological aspects of SWNTs in ultra high molecular weight polyethylene

Zhang Q., Lippits D.R., Vaidya S.N., Rastogi S., Eindhoven University of Technology, NL

A new method is developed to homogeneously disperse single-walled carbon nanotubes bundles (SWNTs) in an intractable polymer, for example, ultrahigh molecular weight polyethylene (Mw>3*106 g/mol) (UHMWPE). The dispersion is obtained by spraying an aqueous solution [...]

Polymer coated Carbon Nanotube probes for Scanning Electrochemical Microscopy

Patil A.V., Vlijm R., Oosterkamp T., Leiden Institute of Physics, NL

We demonstrate a method for fabrication of a Scanning ElectrochemicalMicroscopy (SECM) probe using a parylene coated Carbon Nanotube as a nanoscaleelectrode. Parylene is used to achieve a conformal pinhole free insulatinglayer, which is a major [...]

Recent Enhancements of MOS Model 11

van Langevelde R., Scholten A.J., Klaassen D.B.M., Philips Research Laboratories, NL

MOS Model 11 (MM11) is a surface-potential-based compact MOSFET model, which was introduced in 2001 (level 1100). An update of MM11, level 1101, was introduced in 2002. At the moment a second update of MM11, [...]

Design of Experiment Tools for Process and Device Development

Olij N., Bakker A.F., Nutt A.C.G., PhoeniX BV, NL

The functionality of Micro and Nano Technologies (MNT) device is mainly defined by its shape; for instance a membrane sensitivity to pressure depends on its size and thickness. An MNT device therefore needs a multi [...]

Data Centric Wireless Sensor Networks

Dulman S., Havinga P., Twente University, NL

The vision of wirteless sensing systems requires the development of devices and technologies that can be pervasive without being intrusive. The basic component of such a smart environment will be a small node with sensing [...]

Nanobiotechnology: Responsible Action on Issues in Society and Ethics

Bennett D.J., Schuurbiers D., European Federation of Biotechnology, NL

The overall aim of this initiative is both, firstly, to anticipate the societal and ethical issues likely to arise as nanobiotechnologies develop and, secondly, to use the lessons from the European GM debate to respond [...]

Atomic Force Microscope as a Tool for Nanometer Scale Surface Patterning

Lemeshko S.V., Saunin S.A., Shevyakov V.A., Nanotechnology Instruments Europe B.V., NL

The progress in scanning probe microscopy (SPM) has transformed scanning tunneling microscopes (STMs) and atomic force microscopes (AFMs) from measuring devices into technological tools. Local surface modification by scanning probe allows us to treat materials [...]
