3976. (I) New life for old instrumentation: the revival of a 1981-vintage Bomem DA3 high resolution Fourier transform spectrometer.

Invited Speaker / Conférencier(ère) invité(e)

The Bomem DA3 series of Fourier transform (FT) spectrometers were the first commercially available research-grade instruments of their type. They were available for purchase from 1980-2000. This FT could achieve an ultimate resolution of 0.0025 cm-1, with a resolvance of 106 at any wavelength, impressive specifications even for a similar modern instrument. The scanning Michelson interferometer...

3868. At the tip of an intense laser beam: operando monitoring of laser processing in manufacturing

Oral (Non-Student) / Orale (non-étudiant(e))

A kW laser beam focused on metal creates a highly dynamic environment of considerable importance to automotive production and 3D additive manufacturing. For example, laser welding allows the use of non-traditional materials to reduce vehicle weight (for improved fuel efficiency) but provides no direct on-the-fly quality indicator. The dramatic increase in demand for electric vehicles has...

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

Performing in-situ ion beam analysis to determine metal oxide growth mechanisms poses challenges due to the incompatibility of a electrolyte solution with ultra-high vacuum (UHV). To circumvent this problem, a specialized in-situ cell was developed which isolates the liquid electrolyte from the UHV using a silicon wafer, preventing any contact between vacuum and liquid. This wafer is equipped...

3825. Cross-sectional characterization of the mobility of photovoltaic semiconducting devices via photocarrier extraction by linearly increasing voltage

Oral not-in-competition (Graduate Student) / Orale non-compétitive (Étudiant(e) du 2e ou 3e cycle)

Appropriate characterization is vital for improvement of the electronic properties of semiconductors in photovoltaic devices, which will enable solar energy to compete with non-renewable energy sources. A critical electro-optical characterization tool for determining the carrier mobility in thin-film solar cells is offered by photo-carrier extraction by linearly increasing voltage...

3857. (G*) Hyperoptimization insight for computational morphogenesis

Applied Physics and Instrumentation / Physique appliquée et de l'instrumentation (DAPI / DPAI)

Oral Competition (Graduate Student) / Compétition orale (Étudiant(e) du 2e ou 3e cycle)

The nonlinear relationship between the form and function of physical structures in our built environment raises challenges for design. Modern design methods, such as topology optimization, provide structural solutions but obscure the relationship between the form of the solution and the formulation of the underlying design problem. Here, we show that embedding computational structure design in...
