1D and 2D nanomaterials find uses in diverse areas, from high strength composites to next generation energy storage. In all cases, their many amazing properties are only actually seen when the nanomaterials are separated into individual species.

In our work we use reduction chemistry to individualise species in printable solutions, primarily through creating salts of anionic nanomaterials with metal counter-cations which dissolve spontaneously in polar aprotic solvents. The solutions enable liquid-phase assembly of the nanomaterials through spin-coating, printing and fibre coagulations, which we use to assemble a range of energy generation/storage devices.

Beyond, we can use our chemistries to create entirely new nanomaterials, including turning matchstick heads into quantum dots, and alloying phosphorus with arsenic to make AsP nanoribbons. These newly developed AsPNRs show conducting behaviour at room temperature and exhibit strong edge-derived magnetic properties.

Biography: Dr Adam J Clancy is a Lecturer of inorganic Chemistry and Royce Society URF at UCL Chemistry. He previously held a Ramsay Memorial Fellowship, a Corpus Christi Cambridge Visiting Fellowship, and EPSRC Postdoctoral Fellowship, having initially undertaken his MChem at Cardiff University and PhD at Imperial College, London under Professor Shaffer on structural nanocomposites (and still holds the record strength for PVC composites).
