George Fytas receives ERC Advanced Grant for phononics project

13.07.2016

The external member of the Max Planck Institute for Polymer Research (MPI-P), Prof. Dr. George Fytas, has been granted over two million euros by the European Research Council (ERC) for retrieving a dispersion relation for quantized sound waves, so-called phonons, in soft structures.

Soft materials that are periodic on the submicrometer length scale act as both hypersonic phononic and visible light photonic crystals. This means: they coherently scatter elastic waves as well as light in the visible region. The challenges in understanding and engineering phonon soft matter interactions originate from the fact that phonons, unlike photons, do not propagate in a vacuum and therefore do not move with the speed of light.


Small and nanoscale soft phononics (SmartPhon)

MPI-P

However, together with his team at the MPI-P, Fytas has been able to organize soft matter to go hypersonic. With his Brillouin spectroscopy, a technique that records the frequency and wavelength of phonons through the inelastic scattering of laser light, the Greek scientist has retrieved the dispersion relation for phonons propagating in transparent structures.

“In order to achieve such crystal structures, various self-assembled methods as well as powerful spectroscopic techniques are necessary,” says Fytas. Due to his pioneering contribution in the field of soft matter based phononics, the scientist receives an ERC Advanced Grant for outstanding research leaders amounting to over 2.2 million euros. With this funding, he plans to extend his research project "Small and nanoscale soft Phononics" (SmartPhon) in order to tune phonon propagation in hierarchical materials and to engineer strong wave-matter interactions in the subwavelength range with metamaterial behavior.

Further experiments to be conducted in Germany and Greece

While also relying on strong international relations with several partner institutes, in August 2016, Fytas will start another phase of experiments, conducted at the MPI-P in Mainz, Germany, as well as at the Institute of Electronic Structure and Laser and at the University of Crete, Greece. His findings are anticipated for diverse applications in the field of optomechanics developing tunable responsive filters, one-way phonon waveguides and compact acousto-optic sensors. Moreover, heat management technologies directing the heat flow and its recovery profit from Fytas’s discoveries as well as the research area of materials metrology, which by means of measuring nanomechanical properties, offers insights into the physics of materials.

About George Fytas:
Born in Athens, Greece, Geroge Fytas is professor of Physical Chemistry at the Department of Materials Science & Technology of the University of Crete and Head of the Polymer & Colloid Group of IESL-FORTH in Heraklion, Crete, Greece. As an external member, he has also been conducting research at the MPI-P since 1998 focusing on phonon propagation in structured materials and dynamics including the conformation of complex macromolecular and supramolecular systems. Fytas holds a PhD in Physical Chemistry of the Technical University of Hannover, Germany, and wrote his habilitation thesis at the University of Bielefeld, Germany. The scientist is a Fellow of the American Physical Society and has received a Humboldt Senior Research Award.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

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: 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....
