Bridging the Gap Between Equilibrium Properties and Ultrafast Dynamics with Time-Resolved Spectroscopy of Functional Systems

Creator:: Krueger, Taylor D.
Abstract:: Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...

A force plate for measuring contact forces during dependent transfers onboard aircraft

Creator:: Schafer, Christopher A.
Abstract:: The transfer of air travelers with disabilities between a mobility aid and an aircraft seat is a major source of injury for both the travelers and the airline personnel assisting in the transfer. The risk to both parties might be reduced through the biomechanical study of the transfer task. Such...

Capturing Molecular Movies of Organic and Organometallic Systems in Solution by Ultrafast Spectroscopy

Creator:: Boulanger, Sean A.
Abstract:: Ultrafast spectroscopy can exploit the structure-function relationship of chemical- and biological-based systems. More specifically, femtosecond stimulated Raman spectroscopy (FSRS) provides ground- and excited-state vibrational information with simultaneously high spectral (spatial) and temporal resolutions. The electronic counterpart, femtosecond transient absorption (fs-TA), complements FSRS data analysis as part of a comprehensive approach...
