[2017-10-25] Cell-repellent Surfaces: Poster Award, 2nd Rank

The poster "Laser-induced microstructures on Ti substrates for reduced cell adhesion" by Johannes Heitz et al. received an award at the congress "Kardiologie im Zentrum" which took place on Oct. 21 - 22, 2017 at the Design Center in Linz. The poster reported on laser-induced micro-spikes with the property that mammalian cells can not adhere on these features. These functional surfaces may have interesting applications in the field of medical implants or prostheses, which have to be removed from the body some time after the implantation or which should be overgrown only partially. The work is part of the recently finished FFG project LaMiCell of a.Univ.-Prof. Dr. Johannes Heitz and Univ.-Prof. Dr. Werner Baumgartner at the Institute of Applied Physics and the Institute of Biomedical Mechatronics of the JKU Linz together with Prim. Dr. Doz. Clemens Steinwender of the Kepler University Hospital Linz. Also the Bundesanstalt für Materialforschung und -prüfung (BAM) in Berlin, Germany and the Christian Doppler Laboratory for Combinatorial Oxide Chemistry (at ICTAS, JKU) contributed to the poster.



[2016-09-26] Biomimetic Wetting: Best Presentation Award for Cristina Plamadeala

Cristina Plamadeala has been awarded the Best Presentation Award at the European Materials Research Society (EMRS) 2016 Fall Meeting from September 19 to 22, 2016 in Warsaw - Poland. She received the award in recognition of the Best Student Presentation in Symposium B "Bioinspired and biointegrated materials as frontiers nanomaterials VI". Her presentation was entitled "Three-dimensional laser-written structures fabricated by two-photon polymerization for wetting experiments". She reported on laser-written micro-structures with interesting wetting properties, which are inspired by features occurring at the integument of animals like flat bark bugs and moisture-harvesting lizards. Her results demonstrated that biomimetic surface micro-ornamentation can promote a directional transport of fluids, which may lead to applications in microfluidics and friction reduction. The work is part of her doctoral Thesis, which is performed in the Framework of the European FET Open project LiNaBioFluid (www.laserbiofluid.eu) under supervision of a.Univ.-Prof. Dr. Johannes Heitz and Univ.-Prof. Dr. Werner Baumgartner at the Institute of Applied Physics and the Institute of Biomedical Mechatronics of the JKU Linz.

[2015-10-02] New European Project started at the Institute of Bimoedical Mechatronics and the Institute of Applied Physics of the JKU

The project LiNaBioFluid “Laser-induced Nanostructures as Biomimetic Model of Fluid Transport in the Integument of Animals” has started in recently (www.laserbiofluid.eu). It brings together 7 partners from 4 different countries, including the JKU with the Institutes of Biomedical Mechatronics (www.jku.at/mmt) and the Institute of Applied Physics (www.jku.at/applphys). The project aims on laser-fabrication of biomimetic surfaces with unique wetting properties, which are inspired by the hierarchical micro- and nano- structures at the moisture collecting outer surfaces of flat bark bugs and dessert lizards. The outcome of these innovative wetting effects is expected to lead to radically new technological advances, including reduction in friction and wear in lubricants.
LiNaBioFluid is a Research and Innovation Action funded by the European Community’s Horizon 2020 - FET Open program, which supports early-stage research on concepts for new technologies. The project proposal was strongly based on the ideas of Werner Baumgartner and Johannes Heitz of the Institute of Biomedical Mechatronics and Institute of Applied Physics at the JKU. They are very proud of the success of the proposal as the call in this Excellent Science pillar of the H2020 program was very competitive with a success rate of only 3%.



[2015-09-24] Best Poster Award at EMSLIBS 2015 for Simon Eschlböck-Fuchs

Simon Eschlböck-Fuchs has been awarded the 3rd Prize of the Best Poster Award at the 8th Euro-Mediterranean Symposium on Laser-Induced Breakdown Spectroscopy, held from September 14 to 18, 2015 at JKU Linz, Austria. The Poster was entitled "Tomography of laser-induced plasma for temporally, spectrally and spatially resolved plasma diagnostics using Radon transform technique". Slag samples from industrial steel production (secondary metallurgy) were ablated by intense laser pulses and the properties of the laser-induced plasma were analyzed. The 4D (spatial and temporal) distribution of plasma parameters and optical emission were successfully reconstructed by Radon transform technique. The work is part of his PhD Thesis, which is performed in the Institute of Applied Physics at JKU Linz in co-operation with partners voestalpine Stahl GmbH, Linz, and Federal Institute for Materials Research and Testing, Berlin.

Simon Eschlböck-Fuchs is awarded with the 3rd poster prize of EMSLIBS 2015.



[2015-09-24] 8th EMSLIBS Conference at JKU Linz in September 2015

The 8th Euro-Mediterranean Symposium on Laser Induced Breakdown Spectroscopy, held at the Johannes Kepler University Linz on September 14 – 18 (2015), has been a very successful international conference (http://emslibs2015.jku.at). 200 research scientists from 29 countries and 4 continents contributed with more than 155 presentations to this conference. The scientific presentations were dealing with the newest developments on laser-based techniques for the measurement and analysis of chemical elements and molecules in complex materials (solid, liquid, and gaseous). Laser-induced breakdown spectroscopy (LIBS) was the most important technique reported. LIBS enables a large variety of applications ranging from materials research, industrial production, mineralogy, geochemistry, archeometry, and under-water measurements, e.g. for sea-floor inspection.
Scientific highlights of the conference were, among others, the application of femtosecond laser filaments for stand-off detection (USA), the investigation on early detection of cancer cells (USA), the demonstration of strongly increased detection sensitivity using nano-particles (Italy, Spain), the ongoing successful analysis of Martian soil and rock on board of the NASA rover curiosity (USA, EU), the application of LIBS for molecular and isotope analysis (USA, EU, Israel), and the many industrial applications reported, e.g. on secondary raw materials, recycling, sorting, and process control (EU, China, Russia, Brazil). A further highlight of the EMSLIBS conference was the exhibition of many companies presenting their lasers, spectrometers, technical components, and services.
The conference was held for the first time in Austria. EMSLIBS 2015 was organized by the Institute of Applied Physics at JKU Linz (Conference chairman: A.Univ.Prof. Dr. Johannes D. Pedarnig. Conference website: http://emslibs2015.jku.at/).
