Proteins exhibit structural fluctuations over decades of time scales. From the picosecond
side chain motions to aggregates that form over the course of minutes, characterizing protein …

There is an enormous amount of interest in the structures and formation mechanisms of
amyloid fibers. In this Perspective, we review the most common structural motifs of amyloid …

The introduction of a mobile and polarized organic moiety as a cation in 3D lead-iodide
perovskites brings fascinating optoelectronic properties to these materials. The extent and …

Transient absorption and coherent two-dimensional spectroscopy are widely established
methods for the investigation of ultrafast dynamics in quantum systems. Conventionally, they …

While ultrafast spectroscopy with photocurrent detection was almost unknown before 2012,
in the last 3 years, a number of research groups from different fields have independently …

The majority of 2D IR spectrometers operate at 1-10 kHz using Ti: Sapphire laser
technology. We report a 2D IR spectrometer designed around Yb: KGW laser technology …

The soft character of organic materials leads to strong coupling between molecular, nuclear
and electronic dynamics. This coupling opens the way to influence charge transport in …

Proteins are complex, heterogeneous macromolecules that exist as ensembles of
interconverting states on a complex energy landscape. A complete, molecular-level …

Surface-bound polypeptides and proteins are increasingly used to functionalize inorganic
interfaces such as electrodes, but their structural characterization is exceedingly difficult with …

We report the first wide-field microscope for measuring two-dimensional infrared (2D IR)
spectroscopic images. We concurrently collect more than 16 000 2D IR spectra, made …
