Petrology, Isotope Geochemistry and Cosmochemistry of Planetary Materials

Dr. Bouvier is a Tier II CRC in Planetary Materials in the Department of Earth Sciences at Western University. She studies the chemistry of geological and extra-terrestrial materials using microbeam techniques for sample characterization and multi-collector inductively coupled plasma mass spectrometry (MC-ICPMS) to conduct high-precision isotopic analysis of trace metals (e.g., Pb, U, REE, Hf, Mg). She directs the GEOMETRIC trace metal chemistry laboratory in the Biotron which creates a new integrative research and research training facility that permits to develop innovative analytical tools such as new isotopic systems for tracing the formation of mineral assemblages and decipher the timescales of geological events. These methods can be further developed and applied to a wide range of disciplines including environmental sciences, mineral exploration, medical sciences, and forensics.

Planetary Materials 

Dr. Roberta Flemming is an Associate Professor in the Department of Earth Sciences, and Director of the Powder X-ray diffraction (pXRD) and micro X-ray diffraction (μXRD) Facility (since 2001). She specializes in Earth and planetary mineralogy, studying mineral structure and cation ordering, and as functions of pressure, temperature and composition. She also measures/calibrates strain and strain-related mosaicity in minerals which have undergone tectonic deformation or have been shocked by meteorite impact. She studies minerals from the Earth’s mantle and a variety of meteorites (e.g. chondrites, achondrites, martians), as well as synthetic analogues. Minerals of interest include spinel-group minerals, olivine, clinopyroxene, kimberlite indicator minerals (e.g. garnet), and diamond. She collaborates to study natural glasses, clay minerals and natural zeolites.

Characterization of metal-organic frameworks used for capture and storage of CO2; zeolite and related materials used in petroleum industry 

Zeolites and related molecule sieves are widely used in industry in ion-exchange, gas separation and catalysis. Dr, Huang’s research is centered on (1) the host-guest interaction in zeolitic systems and (2) the crystallization of nanoporous materials under hydrothermal, dry gel conversion and ionothermal conditions. Metal-organic frameworks are a new type of porous materials and they have shown tremendous potentials for gas storage and capture. His recent work is focused on characterization of these new materials by solid-state NMR spectroscopy.

Structures and fabrics in Earth’s crust and mantle, Multiscale simulation of fabric development in Earth materials; Tectonic evolution of orogenic belts 

Dr. Jiang’s research interest lies primarily in using structures and fabrics preserved in Earth’s crust and mantle, observed on small scales such as in field rock exposures, in hand samples, and under microscopes, to unravel large-scale tectonic deformation processes. He integrates fieldwork, laboratory microstructural and texture analysis, and numerical modeling in his research.  He has developed a self-consistent micromechanical approach for modeling multi-scale fabric development during the deformation of the heterogeneous Earth’s lithosphere. The approach provides a rigorous link between structural geology and tectonics.

Metals in Magmatic-Hydrothermal Systems: Research by Prof. Linnen involves experimental and field-based studies on the behavior of metals in high temperature-pressure silicate melts and aqueous fluids. Field-based studies establish the parameters that control metal enrichment in mineral deposits. Parallel to this experimental work includes determining the solubilities and stabilities of metals and minerals in silicate melts and the partitioning of metals between, silicate melts, aqueous fluids and minerals.

Methods for improved analysis of the micro-structure of materials; Laue diffraction, XRD, elastic and plastic deformation, XPS, material surfaces

Dr. McIntyre's research is concentrated on the improvement of microscopic X ray diffraction techniques to understand microscopic deformation processes in metals and ceramics; this includes the role of dislocations and grain boundaries in focusing such forces. As well, he is exploring methods for imaging and mapping of polyphases in the above materials. Improvement of such techniques requires much faster high performance computing processes and more efficient means for transfer of massive blocks of experimental data. Dr. McIntyre also has a continuing interest in the interpretation of photoelectron spectra for use in understanding the surface chemistry of transition metals  and their oxides.

Electrochemistry of materials; corrosion science and engineering; development and application of surface analytical techniques

Research in the Shoesmith laboratory is focussed on the electrochemistry and corrosion science of metal and ceramic oxide systems with a primary emphasis on industrial and environmental applications. Experimentally, the primary goal is to understand the mechanisms and determine the kinetics of a range of reactions involved in surface processes. Based on these fundamental studies, computational models are then developed to describe the behaviour of complex material systems in specific industrial/environmental environments. Presently, these methodologies are being applied in the following areas: (i) the development of nuclear waste containers and the degradation of nuclear waste forms; (ii) the evolution of corrosion conditions on gas transmission pipelines; (iii) the application of light metals in automobile manufacturing; (iv) the performance of in-reactor nuclear materials.

corrosion of nuclear reactor materials, radiation-induced metal oxide nanoparticles and oxide films

Gamma-irradiation creates unique reactive environments that can alter the electric potential field at interfaces and thereby influence mass and charge transfer across phase boundaries. Prof. Wren’s research uses a judicious combination of gamma-irradiation and aqueous conditions to achieve tailored formation of (1) uniform-sized transition metal oxide nanoparticles, (2) very uniform and compact oxide films, and (3) micelles in IL/water systems. Prof. Wren’s research involves both experiments and modelling in these areas to develop a fundamental understanding of interfacial processes.
