Research:

Since July 2011, I am developing my own research line in the direction of artificial photosynthesis with “Towards Bisolar Cells” Grant (983.000 €) Grant idea about artificial photosynthesis is invented, developed by myself. I have initiated a network for the grant (Prof. Gardeniers from University of Twente, Prof. Joost Reek and Prof. Brouwer from University of Amsterdam). I wrote the Twente University part of the grant. 1/3 of the money will be received by the University of Twente.

Brief summary of past research: 

The past research have been dedicated to the development of novel spectroscopy techniques and utilizing them for the purposes of better analyses of chemicals in extraordinary conditions or quantities.

Firstly, a novel X-ray photoelectron spectroscopy that is called is called “pulsed voltage XPS” is developed.

Secondly, In particular so-called MW-AUC ( a novel UV/Vis spectroscopy technique) has been evaluated for separating a semiconductor solution by size in atomic resolution and taking UV/Vis spectra of individual fractions. With the help of this method, quantum size effect for CdTe semiconductors has been studied. During the transfer of this technology to BASF, carbon nanotube and ligand interactions were also analyzed utilizing MW-AUC.

Thirdly, after changing the research topic to microfluidics, the problem of scarcity of the online chemical detection techniques that can work with micro- and nano volumes has been encountered. Another problem was that the techniques had not been designed for specific needs of microfluidic research. The so-called novel Attenuated Total Reflectance Infrared Spectroscopy (ATR-IR) has been developed and infrared spectra of liquids inside lithographically defined nanochannels of nano/microfluidic chips has been recorded. The smallest volume infrared study in the literature has been achieved and the first nanofluidic photoreactor with simultaneous IR analysis has been developed. 

While performing research on microfluidics, a microfluidic approach to photosynthesis has been developed. Utilizing the ‘microfluidic photosynthetic leaf’ recent result about water oxidation inside a microfluidic chip has been achieved. Research on fabricating an artificial leaf is in progress.
