Hi, I am from the University of Applied Sciences in Darmstadt near Frankfurt! I am in Dublin for half a year and hope to finish my studies in November. My work here is focused on the study of the photochemical behaviour of new Ruthenium and Osmium compounds. I like to watch and play football and go fishing, so it is not all about studies! So do not take life too seriously and never give up because you can have a lot of fun here in Dublin!!!

Sabine Horn

I'm from TU-Berlin, Germany, and I'm doing my specialisation practical and diploma thesis in this research group. The aim of my work is to synthesise binuclear Os/Ru-complexes with symmetric and asymmetric ligands of bpy and triazoles. Sometimes synthesis can really drive you mad! ...aber vergeßt nicht: da ist ein Leben außerhalb des Labors!

Andrea Balducci

I graduated in Chemistry at the University of Bologna. For my thesis I worked with Prof. A. Juris on 'artificial antennas' in Prof. Balzani's group. After my degree I worked for 18 months under the supervision of Prof. M. Mastragostino on supercapacitors and lithium-ion batteries. I have started my work in DCU on the SUSANA project under the supervision of Prof. Robert Forster and Prof. Han Vos. This project involves solid-state characterisation and I will use techniques such as AFM, STM, SECM and CV. I'm from Pennabilli, a village in the center of Italy. I like to read and DeLillo, Camus, Nizan and Tondelli are my favourite authors.

Bill Henry

I graduated from U.C.D. with a B.Sc.(Hons.) in Chemistry in 2000. After receiving my degree I travelled to Australia and spent a year working and travelling there. On my return to Ireland I spent 2 months working in the QC department of Roche Irl. in Ennis, followed by a further 9 months in the R & D Department of Phytogen International in Dublin. I joined the Han Vos Research Group in October 2002. At present I am concentrating on the photophysical properties of various heteroleptic polypyridyl Ruthenium complexes. In this work I have been using such techniques such as single photon counting, luminescence spectroscopy and UV-Vis spectroscopy. Soon I hope to begin investigation into the properties of these complexes on surfaces. To do this I will use techniques such as AFM, TEM, SEM and SECM. Some things I like are Liverpool FC, real music and reading almost anything. Some things I don't like are Man U, bands that dance to their songs and George W. Bush.

Stefania Tasca

Hi! I'm Stefania Tasca from Italy. I graduated in Chemistry at the University Statale of Milan, in March 2001. My thesis "Metal-catalysed cycloaddition and insertion reactions of Diazocoumarin" was supervised by Prof. Tollari, in Prof. Cenini's group. I started my Masters on the development of molecular devices based on ruthenium terpyridine complexes at DCU University in July 2002. A tutti i miei amici...una delle frasi che preferisco: "All that I know/There's nothing here to run from,/'Cos yeah, everybody here's got somebody to lean on". (Don't Panic _ Parachutes)

Claire Brennan, B.Sc.(Hons), D.C.U.

I am in the second year of my PhD under the joint supervision of Dr. Mary Pryce and Prof. Han Vos. My research involves the synthesis of Ru(II) 1,2,4-triazole complexes containing a group (VI) metal carbonyl. Ruthenium complexes are of particular interest due to their extensive photophysical and photochemical properties. Coordination of a group (VI) metal carbonyl may further enhance certain photophysical properties of Ru(II) 1,2,4-triazoles. Carbonyl metal complexes also have the potential to act as sensors. The n(CO) vibrational modes in metal carbonyl complexes give rise to strong absorptions in the 2200-1700 cm-1 region of the infrared (IR) spectrum. These occur in a region of the spectrum that is free from interfering absorbances. Hence the monitoring of n (CO) modes in these mixed metal dimers offers the potential for the development of devices where the metal carbonyl can act as a sensor.

Noel O'Boyle

I graduated from NUI, Galway in 2001 with a degree in Chemistry and Applied Chemistry. I am in the second year of a PhD dealing with the synthesis and characterisation of assemblies consisting of ruthenium complexes attached to semiconductor surfaces. Such assemblies are currently of importance in the area of dye-sensitised solar cells. We are interested in the electron-transfer properties of these systems. I have carried out nanosecond transient absorption measurements in Prof. Luisa De Cola's Molecular Photonics Group at the University of Amsterdam. I am also interested in molecular modelling of the electronic structure of ruthenium complexes using the ZINDO semiempirical method. Other interests of mine include computers (I created the group's web pages), badminton and languages (both computer and human!).

FionaF

Fiona Frehill

I did my undergraduate studies at the University of Limerick where I graduated in 2000 with a B.Sc. (Hons) in Industrial Chemistry. I am currently a third year PhD student in the Prof. Han Vos research group. My PhD work focuses on the analysis of dendrimers and ruthenium based polymers on surfaces, and on the chemical functionalisation of carbon nanotubes in colloboration with Dr. Manuel Rüther and Dr. Marc in het Panhuis, Dept. of Physics, TCD. As part of a Marie Curie Scholarship I worked in Nottingham University in collaboration with Dr. Philip Moriarty in the Nanoscience Group, Department of Physics. The type of techniques I use include voltammetric studies, absorption and emission spectroscopy, atomic force microscopy, synchrotron-radiation based measurements using photo electron spectroscopy and NEXAFS spectroscopy. I plan to write up at the end of 2003.

Fiona Lynch

I'm a third year post grad in the Prof. Han Vos research group in DCU. I graduated with a B.Sc.(Hons) from the Analytical Science course in DCU in 2000. My research project focuses on intramolecular electron/proton transfer in ruthenium (II) polypyridyl complexes containing quinone and hydroquinone moieties. In the second year of my post grad I travelled to New Zealand to work with Prof. David Officer in the Nanomaterials Research Centre (NRC) at Massey University. I hope to write-up my thesis at the end of this year but I take heart in the good advice of the Hitchhikers Guide to the Galaxy... "Don't Panic".

Helen Burke, B.Sc. (Hons), D.C.U., AMRSC

I am a final year PhD student and am presently just putting the finishing touches to my thesis! I completed my primary degree in DCU in 1997 obtaining an Honours degree in Pure and Applied Chemistry. My initial work with the Han Vos research group involved the study of the interaction between ruthenium(II) complexes and a Mn(II) bridged ß-cyclodextrin as a possible model for photosystem II. This was carried out in collaboration with Dr. Mary McNamara of the Dublin Institute of Technology, Kevin Street. In 1999 I was given the opportunity to travel to the Universitá di Ferrara, Italy, as part of the Training and Mobility in Research (TMR) Programme entitled 'Heterosupramolecular Chemistry: An Approach to Modulating the Function of Molecular Devices'. There I worked for a year under the supervision of Prof. Franco Scandola and Prof. Maria Teresa Indelli on the synthesis and characterisation of Rh(III) polypyridine complexes with the hope of developing Ru(II)-Rh(III) dinuclear species. Upon my return to DCU I continued my work with Rh(III) and have synthesised and characterised various Rh(III) tris heteroleptic complexes incorporating triazole, triazine and imidazole based ligands. It is this work which is to be presented as my PhD thesis.

Declan Mulhern

I graduated from DCU with a B.Sc. in Chemistry with German in 1997. Part of this study was undertaken in the Friedrich-Schiller Universität, Jena, Germany. I also completed a work placement for Werthenstein Chemie in Luzern, Switzerland. After graduating, I took part in the FAS Overseas Graduate Program and was employed by Mitani Sangyo, a chemical trading company in Tokyo, Japan. I returned to DCU to begin my PhD and am now in my final year. My research interests include Ru(II) carbonyl complexes and the synthesis of novel tris-heteroleptic ruthenium(II) dimers containing triazole bridging ligands. My work involves exploring established synthetic techniques and developing new routes to such complexes.
