Abstract:
Chemistry is deeply connected to nearly every aspect of our lives and will therefore play a key role in addressing global challenges related to health, materials, and energy. In this context, the design and synthesis of new molecular materials remains at the forefront of research aimed at delivering transformative advances. A leading example for such shifts in existing scientific paradigms is surpassing the "thermodynamic limit for single-junction solar cells", which limits the maximum solar conversion efficiency achievable by a single p-n junction solar cell to just over 30%.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...

Phase II Reactions: Miscellaneous Conjugation Reactions
A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...
