Welcome to the research group of Prof. Leone Spiccia

Welcome to Prof. Leone Spiccia's research group at the School of Chemistry at Monash University. We are based in the Clayton campus of Monash University in Clayton, Australia.

Our research interests are divided between renewable energy and diagnostics. Our current research efforts are focused on the area of dye-sensitised and perovskite solar cells, water splitting cells and nanoparticles for cancer imaging.

15 Nov 2016 - An article has been accepted today in the Journal of the American Chemical Society focused on quantifying the catalytic parameters of cobalt, nickel and manganese oxides electrodeposited from borate buffer solutions. The article is now on the ACS website.

8 Sep 2016 - Shannon A. Bonke has had an article published in The Conversation explaining the concept of Solar Fuels to the non-scientific audience. In a sentence the argument is that solar panels cannot power society without storage, but using their power to reassemble fuel and burn it again at night creates a clean and infinite fuel supply.

The title of the paper is "A fast deposition-crystallization procedure for highly efficient lead iodide perovskite thin flm solar cells." Summary of the article:
We report that flat, uniform thin films of CH3NH3PbI3 can be deposited by a one-step, solvent-induced, fast crystallization method involving spin-coating of a DMF solution of CH3NH3PbI3 followed immediately by exposure to chlorobenzene to induce crystallization. Planar heterojunction solar cells constructed with these solution-processed thin films yielded an average power conversion efficiency of 13.9% ± 0.7% and a best efficiency of 16.2% under standard AM1.5G conditions.

23 May 2014 - In collaboration with the group of Xin Li at Harbin Institute of Technology a facile strategy has been developed to improve the performance of aqueous DSC, which uses octadecyltrichlorosilane (ODTS) to form an organic barrier layer (ODTS) on the titania surface. This layer suppresses electron recombination by preventing redox-active species from approaching the titania surface and has resulted in a record aqueous DSCs efficiency of 5.6%.
The resulting article, published on the Angewandte Chemie journal, can be read here.

Cloak of invisibility ‐ Studies on the ability of zwitterionic coatings to minimise the nonspecific adsorption of biomolecules to the surface of nanoparticles thereby enabling them to evade phagocytosis are reviewed. This approach represents a very promising route for the development of clinically-approved nanoparticle-based theranostic agents with fewer off-target effects.
