The aim of our research is to better understand the operating physical and chemical processes which drive material behavior at sliding (i.e., tribological) interfaces. The overarching goal of this research is to transform reliability and efficiency of mechanical systems, as well as to enable new technologies through the development of advanced materials. Our research lies at the intersection of materials science, surface chemistry, classical mechanics, nanotechnology and precision engineering. To enable this work, we utilize experimental techniques both in-situ and ex-situ which probe length-scales ranging from 1 nm to 1 cm.
A key focus of this research is on bridging nano and macro length-scales through the design of novel measurement techniques, instruments and material systems.
Examples of active research topics in the GU Tribology Research Laboratory include:
Multifunctional Polymer and Metal-Matrix Nanocomposites for extreme environments
Novel lubricant additives and basestock: their stability, co-additive interactions and interactions with surfaces
Multi-scale characterization of near-surface tribological and mechanical behavior of materials
Novel SPM-based additive nanomanufacturing techniques
Design and fabrication of precision instruments for multi-scale mechanical and tribological characterization.
