CO2 Capture and Conversion - on a Way Towards a Climate Neutral Synthetic Chemistry

Abstract

Though carbon dioxide represents a waste material, its use as a carbon sustainable feedstock in organic synthesis has aroused global interest. CO2 is a cheap source of carbon, ubiquitous and unlimitedly available, thus provides a viable starting point within the context of sustainable catalysis. In this context, we have proposed CO2 Chemistry as a way towards a climate neutral synthetic chemistry and several strategies including carbon capture and utilization, in situ catalysis, hierarchical reduction to upgrade CO2 into valuable compounds and fuels.

Liang-Nian He obtained a doctorate in Chemistry from Nankai University. He is currently a professor of chemistry at Nankai University, a Fellow of the Royal Society of Chemistry (from 2011), "Chutian Scholarship" Distinguished Professor (from 2009), Bentham Ambassador (from 2016). Prof. He has authored over 200 scientific publications and holds 23 patents and also edited 20 books and chapters. He became one of Most Cited Chinese Researchers, Elsevier in 2014-2018, the top 1% of highly cited authors in RSC journals in 2014-2016.

His current research interests cover green chemistry, catalysis, and CO2 chemistry (CO2 activation and catalytic conversion into fuels/value-added chemicals; in situ transformation of CO2: combination of CO2 capture and subsequent conversion to chemicals and fuel-related products in a carbon neutral cycle, reductive functionalization of CO2), catalysis in green solvents, biomass conversion, and green technology related to desulfurization.

Controlling Bacterial Biofilms with Nitroxides

Abstract

The adhesion of bacteria to surfaces and their subsequent ability to aggregate into colonies called biofilms is a significant global problem in numerous applications, particularly as biofilms display an inherent resistance to antimicrobial agents. Low concentrations of the diatomic free radical nitric oxide has been shown to disperse bacterial biofilms to free swimming planktonic bacteria, which has led to the development of coatings that release nitric oxide. However, the non-systemic delivery of gaseous nitric oxide remains challenging as nitric oxide is an extremely reactive molecule with a very short half-life. As an improved strategy, we have recently shown that nitroxides (persistent and stable free radial species that are sterically hindered versions of nitric oxide) can inhibit bacterial biofilm formation and disperse existing biofilms. This presentation will discuss these results and detail our current work towards the design and development of novel nitroxide-containing anti-biofilm agents and materials.

Bio

Kathryn Fairfull-Smith completed her PhD in 2004 at Griffith University, investigating novel organophosphorus compounds as alternative reagents in the Mitsunobu reaction. She then held postdoctoral positions at the University of Sheffield (England), and at Queensland University of Technology. In 2009 she was awarded a QUT Vice-Chancellor's Research Fellowship to begin her independent research career and also joined the ARC Centre of Excellence for Free Radical Chemistry and Biotechnology as a new chief investigator. In 2012 she was given a permanent position at QUT as a Senior Lecturer and in 2014 she was awarded an ARC Future Fellowship. She was promoted to A/Prof at QUT in 2015. She is currently the Leader of the Molecular Design and Synthesis Discipline at QUT.
