12:00 - SEMINAR - School of Chemistry and Biochemistry Seminar : Luminescent Tetrazolato Complexes: More Information
Luminescent species find applications in a wide variety of fields, including optical technologies and devices, sensors, biomedical diagnostics and many more. Our group is interested in the design of transition metal and lanthanoid coordination compounds that possess phosphorescent properties, as well as their use in materials and life science. This presentation will illustrate efforts within our research group centred on the synthesis of organometallic tetrazolato metal complexes and the investigation of their photophysical properties. As these complexes exhibit efficient luminescent properties, we have also assessed their cellular incubation and cytotoxicity, and the results highlight these species are promising candidates for the design of improved cellular labels. More recent results on the use of N-heterocyclic carbene ligands for the construction of luminescent metal complexes will also be presented.

16:00 - VISITING SPEAKER - The mitochondrial NADH dehydrogenase complex of plants: Function in respiration and photosynthesis : The mitochondrial NADH dehydrogenase complex (complex I) is the largest enzyme complex of the Oxidative Phosphorylation (OXPHOS) system and the main entrance site for electrons into the respiratory electron transfer chain. More Information
Complex I has several unique features in plants. Most notably, it includes 15 extra subunits, some of which introduce side activities into this respiratory enzyme. For example, subunits resembling an archaebacterial gamma-type carbonic anhydrase form an integral part of complex I in plants. These carbonic anhydrase subunits constitute a spherical extra domain which is attached to the membrane arm of complex I on its matrix exposed side. Furthermore, L-galactono-1,4 dehydrogenase (GLDH), which catalyses the terminal step of ascorbate biosynthesis in plants, is associated with complex I in plants. Novel data on the structure of the NADH dehydrogenase complex and its multiple functions in plant cells will be presented and discussed.

12:00 - SEMINAR - School of Chemistry and Biochemistry Seminar : Biomolecular detection via electrochemistry at liquid-liquid interfaces More Information
The beauty of electrochemistry at liquid-liquid interfaces is that it enables the detection of ions or ionisable species by ion-transfer reactions. As a result, problems associated with the detection of analytes by oxidation/reduction reactions at solid electrodes can be surmounted. These problems may include an inability to easily oxidise/reduce the target analyte(s), the simultaneous oxidation/reduction of interferences, or electrode fouling by reaction products. Proteins are extremely important analytical targets because of their roles in regulating biological processes and the fact that diseases often result in changes in protein behaviour. Such altered protein behaviour leads to these biomacromolecules becoming markers or indicators of that disease, so-called biomarkers. Not all proteins are redox-active and even redox-active proteins cannot always be easily detected by oxidation or reduction at a metal or carbon electrode. For this reason, the electrochemical behaviour and electrochemical detection of proteins via ion-transfer reactions at the interface between two immiscible electrolyte solutions (ITIES) has been of growing interest. This presentation will discuss the main idea that electrochemistry at liquid-liquid interfaces enables the detection of ions via non-redox reactions, which may be applied to detection of proteins. Recent progress towards achievement of nanomolar detection of proteins as well as formation and characteristics of nanoscale liquid-liquid interfaces will be presented.

16:00 - VISITING SPEAKER - Wasp Love Got to Do With It? The Evolutionary Implications of Sexual Mimicry in Orchids. : Most flowering plants engage animals to carry out the essential service of pollination. The majority of these plants have evolved flowers that advertise rewards for this service via visual and chemical cues such as petals and scent. There are however a number of species whose false advertisements draw pollinators to rewardless flowers. More Information
My research shows that the chemical mimicry crucial to sexual deception is responsible for reproductive isolation and potentially even speciation. I also show through mating system analysis and studies of wasp behaviour that this strategy is a superbly adaptive solution to the problem flowers face of simultaneously attracting pollinators before persuading them to leave quickly.

12:00 - SEMINAR - School of Chemistry and Biochemistry Seminar : The Carbon Nanoform Jungle: Is Graphene the king? More Information
Carbon nanostructures have been the topic of two Nobel prizes to date, Chemistry in 1996 (fullerenes) and Physics in 2010 (graphene), but carbonís versatile bonding has resulted in the discovery of a wide range of other exotic nanoforms. We will take a quick safari through this jungle of bamboos, peapods, nanohorns, scrolls, nanobuds, etc. To help make sense of this bewildering array of forms I will propose a nomenclature based on their structure.

The underlying structural differences of each carbon nanoform can fundamentally alter their reaction chemistry and mechanical and electronic properties. Using first principles calculations I will examine specific examples where these effects modify the underlying chemistry and physical properties of these materials, such as their oxidation behaviour and mutual interaction. As well as giving unique insight into experimental results, such calculations can predict fascinating new behaviour and open up undiscovered pathways for synthesis and post-processing.

16:00 - SEMINAR - New insights into the proteome of the transcriptionally active chromosome from spinach chloroplasts : Chloroplasts possess their own DNA (ptDNA), which is packaged with proteins proteins into structures analogous to bacterial chromosomes, termed nucleoids or plastid nuclei. Website | More Information
Dr Melonek completed her PhD in 2010 in Plant Cell Biology at University of Kiel, Germany. She continued her work in Kiel for the next 1.5 years but recently moved to Perth to join the ARC Centre of Excellence in Plant Energy Biology at UWA. Her research will focus on characterization of proteins implicated in regulation of chloroplast gene expression in Arabidopsis.

16:00 - SEMINAR - CMCA Seminar Series: "X-ray phase contrast imaging using conventional sources" by Dr Peter Munro More Information
Image contrast arises in conventional X-ray radiography due the differential absorption of X-rays throughout the sample. Many objects of interest, for example, soft biological tissue, possess weak absorption contrast. Furthermore, by definition, absorption contrast is directly correlated with the radiation dose received by the sample. X-ray phase imaging was developed, initially using synchrotron radiation, in order to overcome the limitation of weak absorption contrast. This technique develops contrast based upon the difference in X-ray propagation times through a sample, which, in general, results in greater contrast than absorption based imaging. In this seminar I will discuss how X-ray phase imaging can be performed using conventional X-ray sources such as those used in clinics and give examples from a variety of fields including mammography, non-destructive testing, security screening and small animal imaging.
