Researchers at Northwestern University have created a new method (gradient-assisted multi-dimensional electronic Raman spectroscopy) to extract the static and dynamic structure of complex chemical systems. This new method uses four spectral dimensions to resolve structure to reveal hidden features of molecular structure.
The study of jet disintegration focuses on fuel breakup and mixing within the combustion chamber of propulsion devices.
