Topic description

The intensive use of fossil fuels responsible to a great extent for global warming and for the increasing amount of environmental pollutants are current global challenges that require to be addressed urgently for the safety and prosperity of the biosphere. To this end, this project aims at developing a universal, green “smart matrix” that can promote improved functionalities of various types of responsive devices that, together with their enhanced stability, will trigger the fast deployment of viable renewable technologies.

Various stimuli-responsive nanostructures, obtained through electrografting of “smart” diazonium salts on cheap and transparent materials, will be developed for exploitation in two areas: solar energy conversion and water detoxification. In a first approach, the smart unit will be implemented in a highly structured interface between the electrode surface and biophotocatalysts to generate a novel biohybrid nanoarchitecture with improved solar-conversion efficiency compared to the devices of a similar type. In a second approach, different nanoarchitectures encompassing multiple smart units will be developed to study heavy metals entrapment capability and selectivity. The possibility of a well-controlled release of the captured pollutants using external stimuli will be investigated for the first time.

Centre of New Technologies, University of Warsaw

The Centre of New Technologies (CeNT UW) is an interdisciplinary research institute dedicated to the understanding of important biological, chemical, and physical phenomena. Our scientists tackle fundamental scientific problems as well as collaborate on the translation and application of knowledge to the industry. CeNT UW provides a truly international outlook with an unsurpassed environment for both young and established researchers, as well as promotes the education of the PhD students.

 

Solar energy conversion is one of the few renewable ways to produce clean energy to meet the increasing demands of modern civilization. In the era of global climate change, there is a strong need to understand photosynthetic processes and their regulatory basis, particularly in relation to solar fuel production in extreme environments.

Solar Fuels Laboratory research focuses on three main long-term objectives:

  • to understand the mechanisms of photosynthetic energy conversion at the molecular level in the extremophilic photosynthetic apparatus, using model extremophiles such as the red microalga Cyanidioschyzon merolae and cyanobacterium Thermosynechococcus elongatus,
  • to dissect molecular mechanisms of photosynthetic adaptation under extreme conditions and fluctuating light,
  • to construct truly ‘green’, viable, biohybrid solar-to-fuel nanodevices that mimic the most crucial steps of the early stages of photosynthesis to produce fuels, such as molecular hydrogen and renewable carbon-based fuels.
