A method for the extraction of polyglycerolphosphate polymerase from Bacillus subtilis membranes is described. Further purification by ion-exchange chromatography yields an enzyme fraction totally dependent on the addition of a heat-stable factor for activity. This factor was isolated from cell membranes and acts as an acceptor of glycerolphosphate units. The acceptor contains glycerolphosphate...
We report an efficiency of 6.1% for a solution-processed non-fullerene solar cell using a helical perylene diimide (PDI) dimer as the electron acceptor. Femtosecond transient absorption spectroscopy revealed both electron and hole transfer processes at the donor-acceptor interfaces, indicating that charge carriers are created from photogenerated excitons in both the electron donor and acceptor ...
To minimize the charge recombination between electrons and the electron acceptor in solid-state dye-sensitized solar cells, we propose a separated electron donor and acceptor of a redox couple in the photoanode and in the cathode, respectively. Owing to the absence of the acceptor in the photoanode initially, the charge recombination rate is retarded remarkably, resulting in an increase of the ...
Dopamine functionalized carbon nanoparticles (CNPs) that can act as efficient photoinduced electron donor-acceptor systems depending on the pH of the medium have been synthesized. In acidic media, dopamine on CNPs exists as hydroquinone and serves as an electron donor while under alkaline conditions the corresponding quinone form of dopamine serves as a strong electron acceptor. Application of ...
