    Polymer-Derived Ceramics: 40 Years of Research and Innovation in Advanced Ceramics

    by Paolo Colombo, Gabriela Mera, Ralf Riedel, Gian Domenico Sorarù:

    Abstract

    Preceramic polymers were proposed over 30 years ago as precursors for the fabrication of mainly Si-based advanced ceramics, generally denoted as polymer-derived ceramics (PDCs). The polymer to ceramic transformation process enabled significant technological breakthroughs in ceramic science and technology, such as the development of ceramic fibers, coatings, or ceramics stable at ultrahigh temperatures (up to 2000°C) with respect to decomposition, crystallization, phase separation, and creep. In recent years, several important advances have been achieved such as the discovery of a variety of functional properties associated with PDCs. Moreover, novel insights into their structure at the nanoscale level have contributed to the fundamental understanding of the various useful and unique features of PDCs related to their high chemical durability or high creep resistance or semiconducting behavior.

    Darmstädter Forscher entwickelt hochpräzise Computermodelle

    Forscher der Technischen Universität Darmstadt und des Lawrence Livermore National Laboratory in Kalifornien können erstmals mit neu entwickelten, präzisen Computermodellen den Verformungsprozess metallischer Werkstoffe bis auf einzelne Atome genau vorhersagen. Ihre Arbeit ist jetzt in „Nature“ erschienen.

    Lausanne 2017

    The Microscopy Conference (MC) is one of the most important and prestigious conferences for electron microscopy worldwide. This international event is part of a series of conferences organized every four years by three hosting microscopy societies (German, Swiss and Austrian). This year’s conference was held from the 21-25th of August in Lausanne, Switzerland.

    A one-day focused symposium entitled The Great Transition: the importance of critical metals for green energy technologies was held on the 13th of July, 2017, in the Orangerie in Darmstadt, Germany, with approximately 150 participants in attendance. The program, for which the organization was led by Professor Oliver Gutfleisch of the Technical University of Darmstadt and the Fraunhofer Institute for Materials Recycling and Resource Strategies, focused on the timely transition to renewable energy sources and infrastructure („Energiewende“ in German) and the challenges that materials availability (or scarcity) present in realizing that transition.
