Wissenschaftler messen wichtigen Prozess bei der Umwandlung von Lichtenergie – Publikation in Nature Communications
Einen wichtigen Schritt der Umwandlung von Licht in speicherbare Energie haben Forscher des Karlsruher Instituts für Technologie (KIT), des Fritz-Haber-Instituts Berlin und der Aalto University in Helsinki/Finnland aufgeklärt: Sie untersuchten die Bildung von sogenannten Polaronen in Zinkoxid. Die Pseudoteilchen wandern durch das photoaktive Material, bis sie an einer Grenzschicht in elektrische oder chemische Energie umgewandelt werden. Ihre unter anderem für die Photovoltaik wichtigen Erkenntnisse veröffentlichen die Forscher in der renommierten Zeitschrift Nature Communications.
Dazu hat das KIT eine Pressemitteilung herausgegeben, die auf den Portalen alphagalileo.org und eurekalert.org veröffentlicht wurde. Zur vollständigen Pressemitteilung folgen Sie bitte diesem Link.

Hajo Freund of the Fritz Haber Institute has been selected as the recipient of the 2015 Michel Boudart Award for the Advancement of Catalysis.
The North American Catalysis Society has awarded its 2015 Michel Boudart Award for the Advancement of Catalysis to FHI director Professor Hajo Freund. In its statement the Society says: „We are pleased to announce that Professor Hans Joachim Freund of the Fritz Haber Institute is the recipient of the 2015 Michel Boudart for the Advancement of Catalysis, sponsored by the Haldor Topsøe Company and administered jointly by the North American Catalysis Society and the European Federation of Catalysis Societies. The Award will be presented at the 24th North American Meeting of the Catalysis Society (Pittsburgh, June 2015) and at Europacat XII (Kazan, Russia, August 2015).
This Award recognizes and encourages individual contributions to the elucidation of the mechanism and active sites involved in catalytic phenomena and to the development of new methods or concepts that advance the understanding and the practice of heterogeneous catalysis. It is meant to recognize individuals who bring together the rigor and the international impact that exemplified the accomplishments and the career of Professor Michel Boudart.
Professor Hajo Freund is being specifically recognized for his groundbreaking experimental advances in understanding elementary steps of reactions on catalytic surfaces and for his studies bridging relevant catalysis and surface reactions at single crystal surfaces through the use of novel model catalysts with well-controlled structural features.“ (read the full statement).
Professor Robert Schlögl was awarded the Alwin Mittasch Prize 2015 in March at the Annual Meeting of German Catalysis Scientists in Weimar.
Unicat states: „Robert Schlögl has been a UniCat member since its foundation in 2007 working in the Research Fields D1 and D2. In addition, he is Scientific Director at BasCat, the UniCat BASF Joint Lab.
This prize is conferred in recognition of his extensive contributions to the characterization of heterogeneous catalysts and their preparation for industrial applications, by which he has succeeded in bridging the gap between model catalysis and complex technical catalysis. His work provides a seminal, new understanding of catalytically active materials, thus opening up the way to more effective development of industrially applicable catalysts in the future.
The Alwin Mittasch Prize is awarded to researchers who have both extended the fundamentals of catalysis and found exemplary applications in industrial practice. This prize is announced internationally and comes with a cash sum of 10,000 euros. It is sponsored by BASF SE and is generally conferred by DECHEMA and the German Catalysis Society (GeCatS) every three years. The Alwin Mittasch Prize is Germany’s most prestigious award in catalysis research.“ (read the full statement).
