Futurium Exhibition

The Futurium is about to open tomorrow. And just in time - after dealing with foam bubbles etc. - the solar hydrogen exhibit is installed: When pressing the button, light is turned on and a solar cell coupled to electrodes produces hydrogen and oxygen. The gases are separated by a wedge, collected and consumed in a fuel cell that drives a motor in a plane.

  • 22. July 2019. SciPost Physics has published its 2018 impact factor, self-computed using Crossref data: It's 5.25, quite impressive for such a young physics journal. For now, they're only listed in Web of Science's Emerging Sources Citation Index, and not in the Core Collection, which is why they are not considered in the 'official' Journal Citation Reports.
  • 16. July 2019. I am in the process of constructing a little exhibit for the Futurium museum that is going to open in Berlin in September. Thanks to our workshop, all the parts have finally arrived, now the testing and assembly begins...

  • 17. May 2019. Our paper on the band structure of BiVO4 by angle-resolved photoemission has appeared in RSC Advances.
  • 06. May 2019. Our manuscript "The impact of non-ideal surfaces on the solid-water interaction: a time-resolved adsorption study" has been accepted for publication in SciPost Physics, a so-called two-way open access journal with open peer review.
  • 21. Mar. 2019. Our new preprint "The impact of non-ideal surfaces on the solid-water interaction: a time-resolved adsorption study" is now online on the arXiv (arXiv:1903.08612).
  • 04. Feb. 2019. An overview article "Effiziente Erzeugung regenerativer Brennstoffe über die solare Wasserspaltung" (German only) on solar water splitting has just gone online in Naturwissenschaftliche Rundschau (847, 01/2019, pp. 10-15). Here, I estimate the absorber area needed to produce enough solar hydrogen to satisfy the whole energy demand - i.e. also the ca. 80% beyond electricity - of Germany with 19% solar-to-hydrogen efficiency. It is actually less than the area currently used for energy crops.

  • 23. Jan. 2019. The topic of negative emissions seems to get quite some media attention these days. An interview on our recent paper has gone online in Deutschlandfunk. I hope I could transport the message that "Negative-emission technologies are not an insurance policy, but rather an unjust and high-stakes gamble." as Anderson and Peters put it in their Science perspective. Though we have to think about these technologies, developing and implementing means to reduce emissions - such as Solar Fuels - is much more urgent.
  • 17. Dec. 2018. Our manuscript ESD Ideas: Photoelectrochemical carbon removal as negative emission technology in Earth System Dynamics has been accepted. Update: The final version has appeared as a "highlight article": Earth Syst. Dynam., 10, 1-7, DOI:10.5194/esd-10-1-2019, 2019.

  • 30. Nov. 2018. Great news: I just an Experiment! grant by VolkswagenStiftung on some daring idea for solar water splitting. Thanks a lot to the funder!
