Herstellung von Kohlenstoff-Nanomaterialien Ziel einer Bayreuther Forschungskooperation


Untersuchungen zur Herstellung von Kohlenstoff-Nanomaterialien, um einen massentauglichen Herstellprozess für diese neuartigen Materialien zu entwickeln, sind Ziel einer neuen Bayreuther Forschungskooperation.

Untersuchungen zur Herstellung von Kohlenstoff-Nanomaterialien, um einen massentauglichen Herstellprozess für diese neuartigen Materialien zu entwickeln, werden jetzt im Rahmen eines Forschungskooperation zwischen dem Lehrstuhl für Chemische Verfahrenstechnik der Fakultät für Angewandte Naturwissenschaften/FAN (Prof. Dr.-Ing. Andreas Jess) und der Firma FutureCarbon (Kompetenzzentrum Neue Materialien in Bayreuth) vorgenommen. Das Projekt wird vom Bayerischen Staatsministerium für Wirtschaft, Verkehr und Technologie gefördert und hat eine Laufzeit von Jan. 2004 bis Okt. 2006.

Die Kohlenstoff-Nanomaterialien (sogenannte Multi-Walled-Nanotubes, Platelet-Nanofaser oder Herringbone-Nanofaser) bilden sich aus kohlenstoffhaltigen Gasen (CO, Ethen...). Diese werden über einen geeigneten Katalysator geleitet, auf dem die Fasern aufwachsen. Für die endgültige Form und Art der Nanofaser sind die Temperatur, die Kontaktzeit, die Zusammensetzung des Gases sowie die Art des Katalysators von entscheidender Bedeutung, da sie den Abstand der Graphit-Schichten, die Orientierung der Schichten und die Breite der Fasern beeinflussen.

Bisher werden Kohlenstoff-Nanomaterialien nur im Labormaßstab und überwiegend diskontinuierlich hergestellt. Die typischen Ausbeuten liegen daher nur im Bereich von mg bis g. Für einen breiten Einsatz in der Batterietechnik oder in neuen Verbundmaterialien werden allerdings große Mengen des neuartigen Kohlenstoff-Materials benötigt. Neben systematischen Grundlagenuntersuchungen in Laboranlagen soll im Forschungsprojekt eine Technikumsanlage entwickelt und aufgebaut werden, in der Proben im Kilogrammmaßstab produziert werden können.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...

Im Focus: Wrinkles give heat a jolt in pillared graphene

Rice University researchers test 3-D carbon nanostructures' thermal transport abilities

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University...
