Two-Dimensional Spectroscopy Is Being Used to Address Core Scientific Questions in Biology and Materials Science
TLDR
The ways in which two-dimensional visible and infrared spectroscopies are being applied to elucidate fundamental details of important processes in biological and materials science are provided.Abstract:
Two-dimensional spectroscopy is a powerful tool for extracting structural and dynamic information from a wide range of chemical systems. We provide a brief overview of the ways in which two-dimensional visible and infrared spectroscopies are being applied to elucidate fundamental details of important processes in biological and materials science. The topics covered include amyloid proteins, photosynthetic complexes, ion channels, photovoltaics, batteries, as well as a variety of promising new methods in two-dimensional spectroscopy.read more

Interfacial H-Bond Dynamics in Reverse Micelles: The Role of Surfactant Heterogeneity.
TL;DR: Simulations indicate that structural diversity leads to decreased packing efficiency, which in turn drives water further into the otherwise hydrophobic region, and Interestingly, this increase in hydration is accompanied by a slowdown of dynamics, indicating that water molecules solvating surfactants are conformationally constrained.
