Dr. Gillian Collins
Gillian is a researcher in the Materials Chemistry and Analysis Group. Her current research focuses on the synthesis of noble metal (Pd, Pt, Ru, Au, Ag,) nanoparticles, alloyed nanoparticles and oxide supported nanostructures for heterogeneous catalytic applications; surface and interface analysis (SEM, TEM, EDX, XPS) of noble metal nanowires and core-shell structures; understanding structure-property relationships in nanomaterials such as such as the influence of size, shape and crystal defects on catalytic activity of noble metal nanoparticles.
Prof. Justin Holmes
Every aspect of basic nanoscale science, as well as the commercial production of nanotechnologies, is dependent upon the capacity of instruments and methodologies to fabricate, measure, sense and manipulate matter at the nanoscale. The Materials Chemistry and Analysis Group (MCAG) focus on developing chemical methods for synthesising and assembling nanostructured materials and their in-depth characterisation. In particular, we are interested in understanding nanoscale phenomenon in materials and determining structure-property relationships that enable the creation of functional devices for electronic, sensing, energy and catalytic applications.
Central to the group’s research is the combination of 'bottom-up' synthetic methods with 'top-down' integration and processing techniques. Material sets of interest include semiconductor nanowires, porous oxide films, metal nanoparticles, chemically modified semiconductor surfaces, functional carbon materials, polymer thin films and others. The MCAG also has expertise in the synthesis, functionalisation and assembly of semiconductor nanowires towards useful devices and their detailed analysis by microscopy and spectroscopy techniques. For example, MCAG researchers have previously developed processes for manufacturing and integrating Si and Ge nanowires into nanoelectronic, photovoltaic and sensor devices.
Prof. Paul Hurley
Paul leads a research team of ten PhD students, post-doctoral researchers, visiting students and Tyndall Research staff who perform basic research on high dielectric constant (high-k) thin films for applications in nanoelectronics. The current research work covers use of high-k oxides in conjunction with III-V and 2D semiconductor materials for future energy efficient logic devices and the use of high-k films in integrated capacitors. The groups are also exploring the use of MOS systems in energy applications as well as investigating the electrical properties of emerging phase change materials. Paul received an Intel Outstanding Researcher award for his work in high-k/III-V interface defect studies in 2012.
Paul is a member of the Technical Committee of the Insulating Films on Semiconductors (INFOS) conference and the International Workshop on Dielectrics in Microelectronics (WoDiM). In addition to research activities, he is a part time lecturer in the Department of Electrical Engineering at University College Cork. He has published over one hundred papers in the field of micro and nanoelectronics, and has given over 25 invited presentations and seminars in the high-k area from 2006 to 2014.
Dr. Simon Lawrence
Simon's research interests are in understanding and controlling the organic solid state, encompassing crystal engineering, co-crystallization, polymorphism and nucleation itself.
Current projects are investigating the co-crystallization of nutraceuticals, the use of cocrystals for chiral resolution and the structure of the solution phase and nucleation.
Dr. Orla Ni Dhubhghaill
Research in Orla Ni Dhubhghaill’s laboratory is in bioinorganic chemistry with particular emphasis on the design and synthesis of coordination complexes with potential biological activity.
Work in the group focusses on (i) design and synthesis of novel hemi-labile ligands of the types P,N,O-, P,N,S-, or P,N,N--; (ii) development of synthetic routes to Group 10 (Pd, Pt) and Group 11 (Cu, Ag) complexes of these and (iii) investigations of the reactivity of the complexes with biologically relevant ligands.
In addition, we have prepared a series of novel cyclometallated Group 10 complexes including platinum(IV) complexes. Investigations on selected complexes indicate excellent DNA binding capacity as well as some cytotoxicity. Work is ongoing on further establishing structure activity-relationships for these complexes.
Prof. Colm O'Dwyer
Prof. O'Dwyer's research in the Applied Nanoscience Group researches the functional properties of material structures and their arrangements. A lot of the work involves the intriguing characteristics of materials chemistry and physics and how fundamental properties can add function. His group study fundamental optical, electrical, structural, electrochemical, and chemical properties of a wide range of semiconducting, inorganic and organic materials and structures to find and understand new knowledge and determine their potential for application ranging from electronics and photonics, to energy storage and conversion.
Their research includes advances in the growth and device-inspired investigations of metal oxides and semiconductors for electronics and photonics, including transparent conducting materials, thin film transistors, and light-matter interactions including plasmonic coupling effects, antireflection, enhanced transmission etc. from a range of nanoscale materials on optoelectronic devices.
They have also extensive experience in charge storage research including Li-ion and Li-O2 batteries and processes that affect their operation, and research that includes semiconductor (photo)electrochemistry, and photonic crystals and their assembly for energy storage. On the ‘dry’ side, our research interests extend to charge transport phenomena in semiconducting, oxide and related materials, porous III-N and III-V semiconductors, electro-optic thin films and devices, nanoscale thermoelectrics using 2D crystalline materials and nanoscale silicon, with a strong background in electron microscopy and spectroscopy to probe materials and properties.
The research focuses on fundamental investigations that are applicable to materials, devices, properties, and use interesting phenomena for function and analysis. They do this research in the School of Chemistry, and in collaboration with a wide range of scientists and industries in Ireland, throughout Europe and further afield.
