Topics in Designing Low Thermal Expansion Lattices at the Microscale

Topics in Designing Low Thermal Expansion Lattices at the Microscale John Chu Master of Applied Science Graduate Department of Aerospace Science and Engineering University of Toronto 2011 Microscale bi-material lattices with near zero thermal expansion are designed to create a thermally stable optical surface for applications in a space telescope. To facilitate the design, the thermal expansion...

Dental tribology at the microscale

Dental wear caused by tooth care is a complex phenomenon that depends on the quality of the tooth material, the type of toothbrush and the brushing slurry. Tooth wear is commonly determined in abrasion experiments using a standardized toothbrush in contact with a radioactively labeled dentin sample (RDA method). The increase of radioactivity in the slurry is a direct and highly-sensitive indica...

Rapid PCR Thermocycling using Microscale Thermal Convection

Many molecular biology assays depend in some way on the polymerase chain reaction (PCR) to amplify an initially dilute target DNA sample to a detectable concentration level. But the design of conventional PCR thermocycling hardware, predominantly based on massive metal heating blocks whose temperature is regulated by thermoelectric heaters, severely limits the achievable reaction speed(1). Cons...

Microscale Metallography Using Focused Ion Beam

Microstructural examination can provide a rich tapestry of information about the processing and application history of a metal component. For this reason, microstructural characterization is a fundamental tool for failure analysis of these components. To reduce costs and accommodate demands for smaller packaging, many applications currently use metallic components where the critical dimensions ...
