30013 Projects Semester 2, 2014

Aug 8 14

The NSL is offering 2 30013 projects in 2014 for 3rd year chemistry majors.

Project 1 – ZnO Nanocrystals for solution-processed LEDs and solar cells

Description: Zinc oxide nanoparticles (ZnO NPs) are increasingly used as electron-transport layers in a wide range of solution-processed devices such as solar cells, LEDs, and transistors. The synthesis of ZnO NPs is done via hydrolysis of Zn2+ salts (typically zinc acetate) using a base (typically KOH or tetramethylammonium hydroxide, TMAH). This project will investigate the effects the choice of base, synthesis parameters, and post-synthesis processing have on the resultant ZnO NP properties and their performance in electronic devices.

Time commitment & location: The project will require 1-3 days per week of work at Melbourne University to work on the synthesis and characterisation of the ZnO NPs. Devices will be fabricated at CSIRO in Clayton on a weekly or fortnightly basis and there is a possibility the student can participate in this process subject to travel and access arrangements.

Suitable students: The project is suitable for a student with an interest in inorganic chemistry, nanotechnology, and/or device physics. Prior knowledge of device physics is NOT required.

Project 2- Near Infra Red emitting Semiconductor Nanocrystals for Bio-imaging

Description: Fluorescent nanocrystals (NCs) have been utilised in biological and life science research for assay detection as well as in-vitro imaging for their unique optical properties.  We have recently developed a technology at Bio21 for conjugating visible emitting NCs to biomolecules. This project involves exploring various synthetic routes to expand our current NC library to near infra-red emitting particles. The resultant NCs then will be functionalised in preparation for bioconjugation.

Time commitment & location: The project will require 1-3 days per week of work at Melbourne University.

Suitable students: The project is suitable for a student with an interest in synthesis, surface chemistry, nanotechnology, and bio applications.

This is the website of the NanoScience Laboratory at the University of Melbourne. Our laboratory is dedicated to research into the physics and chemistry of nanoscale systems. We also do small scale materials development for commercial customers. Our work is funded primarily by the Australian Research Council through the Laureate Fellowship and Discovery Grants Programs. We also receive support from the Alexander von Humboldt Foundation, Go8-DAAD, US AOARD program, VLSCI Supercomputing, IBM (Melbourne) and CSIRO.

Current funding focusses on nanoscale catalysis, AFM, self-assembly, single quantum dot spectroscopy and plasmonics. Our research group currently has some 20 members, including 5 postdoctoral research fellows and 13 PhD students. Our group currently has members from 10 countries including China, India, Germany, Italy, Lebanon, NZ, Netherlands, US, France and Australia.

Some of our research will be presented at the ACS Dallas, NaNax6 (Austria), ICONN2014 (Adelaide) and the MRS (Boston) 2014 conferences. We hope to see you there.
