Machine Learning Based Detection and Deep Learning Based Image Inpainting of Preparation Artefacts in Micrographs

Jansche A., Choudhary A.K., Bernthaler T., Schneider G., Aalen University, DE

Artefacts like stains or scratches introduced during the metallographic sample preparation process are a problem for manual as well as automatic image analysis. We show the use of image inpainting – normally used for reconstruction [...]

Machine Learning for Microstructures Classification in Functional Materials

Choudhary A.K., Jansche A., Grubesa T., Bernthaler T., Schneider G., Aalen University, DE

The search for novel magnetic phases requires efficient quantitative microstructure analysis to extract microstructural information and to correlate it with its intrinsic magnetic parameters. Kerr micrographs of magnets hold vital information for analysing the distribution [...]

Flexible virtual source compact model for fast modeling of new channel materials and device architectures

Wolf F., Mothes S., TU Dresden, DE

The end of bulk silicon-based transistor technology has often been predicted in the scientific and technical literature. As a result, many new channel materials (such as III-V semiconductors, 2D materials, nanowires and -tubes) and device [...]

Silicon lens arrays for wafer level packaging of IR-sensors

Kulkarni A., Stenchly V., Quenzer J., Dudde R., Fraunhofer Institute Silicon Technology, DE

A new process technology has been developed for a cost efficient production of refractive convex lenses made of silicon. These lenses are produced as lens arrays on standard 8 inch silicon wafers to allow the [...]

Materials data management in research & development: improving innovation and product liability

Ehrig T., Klepsch L., IMA Materialforschung und Anwendungstechnik GmbH, DE

Challenge Companies produce a huge amount of notes and tables, especially for their research and development processes. A lot of different tools are used to store such information:  Note-taking apps, like Mind-Mappers, One-Note, ... [...]

Melt-mixed thermoplastic polymer/carbon nanotube composites for thermoelectric applications

Pötschke P., Krause B., Luo J., Leibniz Institute of Polymer Research Dresden (IPF), DE

Thermoelectric generators (TEG), which can convert waste heat directly into electricity, are one type of promising energy harvesting devices. The thermoelectric (TE) effect (also called Seebeck effect) describes an electrical potential (voltage ∆U) induced by [...]

A New Sonochemical Synthesis Route for Silicon Nanoparticle Inks for Energy and Nanomedical Applications

Cádiz Bedini A.P., Chen C., Klingebiel B., Notten P.H.L., Rau U., Forschungszentrum Jülich, DE

Silicon nanoparticles (Si-NPs) have become increasingly relevant in several important fields ranging from solar cells, next-generation quantum dot LEDs, lithium-ion batteries, and because silicon is biodegradable, their use as drug carriers or fluorescent markers has [...]

Highly luminescent Ca3Sc2Si3O12:Ce3+ silicate garnet nano- and microparticles with 50-70% photoluminescence quantum yields as efficient phosphor converters for white LEDs

Levchuk I., Schröppel F., Römling L., Osvet A., Khaidukov N., Zorenko Y., Van Deun R., Batentschuk M., Brabec C.J., University of Erlangen-Nuremberg, DE

Solid state lighting based upon a combination of violet/blue light emitting diodes (LEDs) and a phosphor converter created enormous commercial interest because of the potentially higher efficacies and long lifetimes of these light sources. Most [...]

Development of a Gold Nanoparticle Conductive Ink with a Relatively Low Sintering Temperature

Hamacher S., Bachmann B., Yakushenko A., Forschungszentrum Jülich, DE

Inkjet printing is a widely used and a well-known technique, which has been recently used for deposition of functional materials, such as conductive inks for the fabrication of low-cost electronic systems. Nowadays, a variety of [...]

TechnoEconomicEnvironmental Assessment Method for CO2Utilization in Chemicals Production Based on Evidence from StartUps and Literature

Zimmermann A., Kant M., Schomäcker R., Kratzer J., TU Berlin, DE

Greenhouse gas emissions and the resulting anthropogenic climate change create tremendous economic, ecologic and social challenges for societies today and in the future. To mitigate these effects, world leaders agreed to limit global warming to [...]
