2159. Gas Flow Velocity Field and Turbulent Anisotropy Measurements using Magnetic Resonance Imaging (G)*

Amy-Rae Gauthier (University of New Brunswick)

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

Fluid turbulence has been called the “last unsolved problem of classical physics” and the measurement of this phenomenon presents a formidable challenge. Turbulent systems are highly sensitive to perturbations, and so a non-invasive technique is needed to probe their properties. Turbulence is also difficult to fully characterize, particularly in the case of anisotropic turbulence. Magnetic...

1956. A New Pathway for Robust High-Resolution Imaging and Quantitative Force Spectroscopy in Vacuum: Tuned-Oscillator Atomic Force Microscopy

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

Since the first demonstration of atomic resolution in ultra-high vacuum more than twenty years ago, frequency modulation-based noncontact atomic force microscopy (FM-NC-AFM) has significantly matured and is now routinely applied to study problems that benefit from high-resolution surface imaging. In FM-NC-AFM, control of the tip’s vertical position is accomplished by detecting a shift in the...

2123. Multi-Wavelength Light Trapping Using Width-Graded Plasmonic Nanogratings (G)*

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

Light incident on nanoscale metal-insulator-metal (MIM) plasmonic gratings generates surface plasmon polaritons (SPPs) which resonate and propagate within the grating structure. A variation in the SPP resonant wavelength is achieved by gradually increasing the width of the MIM grooves symmetrically about a central groove to create a graded grating, which leads to a gradient in the effective...

2158. On an alternative neutron source

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

Traditional point sources of neutrons produce free neutrons in isotropic directions and with kinetic energy in the MeV energy domain. These neutrons are too fast for many applications as the probability of interaction between neutrons and surrounding matter is often higher at low neutron energies. Therefore, to optimize interaction between neutrons and its environment, these neutrons are...
