We are pleased to present Professor Paul Mulvaney to speak on Spectroscopy of Gold Nanocrystals – Pressure, Assembly and Sizing

Date: 17th November 2022

Time: 12:30pm

Venue: AIBN Level 1 Seminar room and online via zoom https://uqz.zoom.us/j/webinar/81920361276

Abstract

Gold nanocrystals have long been a model system in colloid science. But there remain many intriguing scientific questions to solve. These include:

•         The mechanical properties of nanoscale materials – are they really stronger than bulk materials?
•         Nanoscale assembly – can we ever create arbitrary structures from colloids through chemical or directed assembly?
•         What is the optimal way to size nanocrystals? Is TEM the best method?

In this overview, I will present some of our lab’s recent work on these topics. What links the approaches is the use of spectroscopy as the key tool to elucidate answers to these questions.

Bio

 

Prof. Paul Mulvaney is Laureate Professor of Chemistry in the School of Chemistry at the University of Melbourne. He currently serves as the Director of the ARC Centre of Excellence in Exciton Science.

He received his PhD degree at the University of Melbourne in 1989. He worked as a research associate at the ANU Applied Maths Department (1988-89) and the Argonne National Laboratory in Chicago in 1986-87, 88. He was appointed as a research scientist at the Hahn-Meitner-Institute for Nuclear Research in Berlin from 1989-1992. In 1993, he returned to the University of Melbourne as an ARC QEII Research Fellow, and he accepted a Faculty position in 1997. In 1999, he spent time in Palo Alto with Quantum Dot Corporation. He was a Humboldt Research Fellow in 2000 at the Max-Planck Insitute for Colloids and Surfaces in Golm and again in 2005 at the CAESAR Nanotechnology Institute in Bonn. Between 2006 and 2010 he was an ARC Federation Fellow and from 2011 to 2015, he was an ARC Laureate Fellow. In 2009, Mulvaney was made a Fellow of the Australian Academy of Science and in 2014 a Fellow of the Royal Society of Chemistry in the UK. He chaired the National Committee for Chemistry from 2014-2016.
 
His current interests include the optical properties of single quantum dots, surface plasmon spectroscopy of single metal particles, nanocrystal based electronics, nanomechanics and solar energy conversion. To date he has published some 350 scientific papers averaging around 140 citations per publication.
