We engineer colloidal quantum dot nanocrystals through the choice of biomolecular ligands responsible for nanoparticle nucleation, growth, stabilization, and passivation. We systematically vary the presence of, and thereby elucidate the role of, phosphate groups and a multiplicity of functionalities on the mononucleotides used as ligands. The results(More)
Physically flexible, solution-processed solar cells have the potential to harvest light conveniently, cheaply and efficiently. Absorption of the considerable power in the infrared region of the solar spectrum is necessary for efficient solution-processed solar cells. We use lead sulphide (PbS) colloidal nanoparticles (quantum dots) that are quantum size(More)
Electrolytic solutions of lithium-ion batteries can be modified with additives to improve their stability and safety. Electroactive molecules can be used as such additives to act as an electron (redox) shuttle between the two electrodes to prevent overcharging. The electroactive ionic liquid, 1-ferrocenylmethyl-3-methylimidazolium(More)
