Lipid Dip-Pen Nanolithography for Functional Biomimetic Membrane Systems

Lenhert S., Forschungszentrum Karlsruhe GmbH, DE

Dip Pen Nanolithography (DPN) is uniquely well suited for the integration of multiple materials (or inks) with both high resolution and high throughput. Phospholipid-based inks are particularly well suited for this purpose for several reasons. [...]

Biofunctional core-shell nanoparticle deposition for biochip creation by printing processes

Borchers K., Weber A., Genov S., Wirth I., Grzesiak A., Tovar G.E.M., Fraunhofer Institute for Interfacial Engineering and Biotechnology, DE

Nanoparticles display a very large surface-area. Therefore, coatings of functional nanoparticles adsorbed to a solid substrate yield an enlarged interface per footprint-area which is highly appreciated for probe-immobilization in bio-chip technology [1,2]. Silica nanospheres, equipped [...]

Influence of the crystallite size of BaTiO3 on the dielectric properties of polyester reactive resin composite materials

Schumacher B., Geßwein H., Hanemann T., Haußelt J., Forschungszentrum Karlsruhe, DE

Today’s electric equipment has to be small in dimension and rich in functionality to be successful with the customer. The available surface area on today’s printed circuit boards (PCB) is decreasing as a result and [...]

Towards Automation in the Characterization of Nanostructured Materials and Devices

Weishaupt K., Schmidt U., Dieing T., Hollricher O., WITec GmbH, DE

The characterization of nanostructured materials implies knowledge about their chemical and structural properties, leading to a growing demand for characterization methods for heterogeneous materials on the nanometer scale. However, certain properties are difficult to study [...]

Nanoscale Deformation Measurements – Concepts for Failure and Reliability Assessment at the Nanoscale

Michel B., Gollhardt A., Keller J., Fraunhofer Institute for Reliability and Microintegration, DE

The paper presents two methods for deformation measurement at the nanoscale level. The first method is based on Scanning Probe Microscopy (SPM) in combination with Digital Image Correlation (DIC). The technique serves as the basis [...]

Metallic submicron wires and nanolawn for microelectronic packaging. Concept and first evaluation

Fiedler S., Zwanzig M., Schmidt R., Scheel W., Fraunhofer Institut Zuverlässigkeit und Mikrointegration (IZM), Berlin, DE

Starting with a brief review of submicron wire production techniques, promising applications of submicron and nano wires are discussed. Observed attractive properties of metal rod decorated metal surfaces, so called nano lawn, for low energy [...]

Residual Stress Measurements of High Spatial Resolution

Vogel D., Luczak F., Michel B., Fraunhofer Institute for Reliability and Microintegration, DE

Residual stresses in semiconductor and MEMS devices superposing functional and environmental loading are one of the crucial reliability issues as they can add significant stress levels leading finally to component damage. Most of routinely used [...]

Synthesis, Reliability and Applications of Nanocrystalline CVD-grown Diamond and MicroDevice Fabrication

Wiora M., Brühne K., Flöter A.C., Gluche P., Fecht H-J., University of Ulm, DE

The correlation between the micro- and nanostructure of a material and its physical and chemical properties is the key issue in materials development. Considerable progress has been achieved recently by the development of new processing [...]

Development of nanocomposites with carbon nanotubes in a thermoplastic elastomer matrix

Broza G., Roslaniec Z., Schulte K., Technische Universitaet Hamburg, TUHH, DE

Thermoplastic elastomers (TPEs) have the potential for application as engineering materials because of their novel properties and ease of processing. We have developed a polycondensation process, which allows the manufacturing of polybutylene terephthalate/polyoxytetramethylene (PBT/PTMO) block [...]

Microbial fuel cell

Willert-Porada M., Lorenz K., Freitag R., Jerome V., Peiffer S., University of Bayreuth, DE

Polymer electrolyte fuel cells, PE-FC, use hydrogen or methanol as fuel. Water soluble organic compounds, like starch, glucose, acetates, can not serve as fuel because of limited catalytic activity of common metal catalysts. Opposite to [...]
