The Department of Applied Oral Sciences is a research unit within the Faculty of Dentistry at Dalhousie University. Working closely with the Department of Biomedical Engineering, Applied Oral Sciences faculty and staff focus their materials research mainly around glasses for biological applications, as well as tissue engineering. Instrumentation such as ICP-OES, DSC, mechanical testing units and a variety of other materials characterization equipment are available within the Department.
- Chemistry and Biochemistry
- Engineering - Chemical, Nuclear, Other

- Life Sciences, Pharmaceuticals and Medical Equipment
Generally used in materials characterization to provide heat capacity data as well as temperature information such as inset temperature, melting point, and glass transition. This model allows for simultaneous collection of thermal gravimetric data, allowing correlation of mass and energy data from one instrument.
- The carbide furnace chamber is purged with N2 to provide an inert atmosphere and avoiding combustion.
- Temperature range of room temperature to 1500 Celsius.
- Ramp rates are generally between 5-20 K/min.
- Sample size is generally ~20 mg.
Simultaneous analysis of up to 60 elements in nitric acid. Can be used both in both axial and radial modes to increase sensitivity and detection.
Note: This instrument is designated as a non-HF instrument.
To analyse particle size of solids suspended in a liquid medium, using dynamic light scattering.
Particle range between 0.01 - 3500 micron.
Precise mechanical testing with force and displacement, with measurement of deformation her six orders of magnitude (nm - mm). Generally used for Young's Modulus and hardness testing.
- <0.01 nm displacement resolution
