PhD position on artificial photosynthesis at sub-zero temperatures within cryo-protective lipidic mesophase nanoconfinement (P2406) 100%

Your position

Photosynthesis is a critical process that captures carbon dioxide (CO2) from the atmosphere and transforms it into organic matter, which forms the primary source of the Earth's biomass and energy storage. However, in polar regions and during winters, the natural photosynthetic activity ceases due to the low temperature. This project aims to develop an unfrozen artificial photosynthetic platform using nanoconfinement to keep water liquid and enable CO2 fixation at sub-zero temperatures. Lipidic mesophases have proven effective for other enzymatic reactions down to -20 °C. Utilizing this platform, we will incorporate thylakoid membranes from pea plants, containing all necessary enzymes for photosynthesis. The efficiency of this nano-platform at low temperatures will be tested by measuring the generation of adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH). Combination of techniques such as small-angle X-ray and neutron scattering (SAXS and SANS), differential scanning calorimetry (DSC), broadband dielectric spectroscopy (BDS), and quasi-elastic neutron scattering (QENS) will be employed to analyse nanoscale self-assembly and the impact of molecular dynamics on photosynthetic efficiency at low temperatures.
