Usage of Solar Energy for the Bioelectrocatalysis – Photobiohybrid Eletrodes for the Light-Driven Synthesis of Valuable Substances (II, SP B)

Zouni, Athina, PD Dr. (Honorary Chairs / Professors by Special Appointment / Part-Time Lecturers)

Duration of Project: 02/2018 - 01/2021

The aims of the Tandem-project are light-triggered electrodes for efficient energy conversion. In the frame of the prolonged period of work it is planned to increase the efficiency of photobio-electrodes and also to couple them with enzymatic convers ...

Elucidation of the self-repair mechanism of the light-driven water oxidation in photosystem II (PSII): Crystallization of the Mn-depleted PSII and its structural/functional analysis

Zouni, Athina, PD Dr. (Honorary Chairs / Professors by Special Appointment / Part-Time Lecturers)

Duration of Project: 11/2012 - 10/2017

Photosystem II (PSII) of oxygenic photosynthesis has the unique capability of utilizing visible light to oxidize water at the Mn4CaO5-cluster (the water oxidizing complex, WOC). Important progress in elucidating the molecular structure of the WOC has ...

Elucidation of the photo-assembly mechanism of the light-driven water oxidizing complex in photosystem II

Zouni, Athina, PD Dr. (Honorary Chairs / Professors by Special Appointment / Part-Time Lecturers)

Duration of Project: 11/2017 - 12/2018

Oxygen photosynthesis in green plants, algae and cyanobacteria is catalyzed by the two large membrane protein complexes Photosystem I (PSI) and Photosystem II (PSII). Both complexes contain a reaction center (RC) that conducts a light-driven charge t ...

Bestimmung der Translationstemperatur bei der Hochdruck-Molekularstrahlexpansion kleiner Moleküle (II)

Christen, Wolfgang, Prof. Dr. rer. nat. (Physical and Theoretical Chemistry III)

Duration of Project: 01/2008 - 06/2009

Überkritische Fluide werden vielfach als Lösungsmittel und zum Transport nichtflüchtiger und thermisch labiler Moleküle eingesetzt. Ihre Überschallexpansion im Molekularstrahl ist hinsichtlich der grundlegenden Prozesse wie adiabatische Abkühlung und ...

Bestimmung der Translationstemperatur bei der Hochdruck-Molekularstrahlexpansion kleiner Moleküle (I)

Christen, Wolfgang, Prof. Dr. rer. nat. (Physical and Theoretical Chemistry III)

Duration of Project: 07/2006 - 06/2007

Eine aktuelle Frage bei der Anwendung gepulster Überschall-Molekularstrahlen betrifft die bei einer Hochdruckexpansion maximal erzielbare Abkühlung der Moleküle. Während hohe Stagnationsdrücke bereits erfolgreich eingesetzt werden, um mittels überkri ...
