Journal ArticleDOI
Ultrafast Transient Holographic Microscopy
TL;DR: An ultrafast holographic transient microscope is introduced for wide-field transient nanoscale imaging with high frequency all-optical signal demodulation and time-resolved spectroscopy of gold nanoparticles over a large volume irrespective of their x-y-z position is demonstrated.
Journal ArticleDOI
Raman spectroscopy: Watching a molecule breathe
TL;DR: In this article, the authors propose to use the single-molecule detection ability of surface-enhanced Raman scattering with the extreme time resolution of ultrafast coherent spectroscopy to detect the vibrations of a single molecule.
Journal ArticleDOI
Photocurrent-Detected 2D Electronic Spectroscopy Reveals Ultrafast Hole Transfer in Operating PM6/Y6 Organic Solar Cells.

TL;DR: Spatiotemporal thermoelectric microscopy is introduced with femtosecond temporal and nanometre spatial resolution and enables the observation of electronic heat flow in graphene in diffusive and hydrodynamic regimes at room temperature, as well as a controlled transition from a Fermi liquid to Dirac fluid.
Journal ArticleDOI
Second-order nonlinear optical active calix[4]arene polyimides suitable for frequency doubling in the UV region
TL;DR: In this article, a new type of soluble calix[4]arene-based polyimides was prepared by reaction of bis(3-aminopropyl) dipropyl functionalized tetranitrocalix [4]-arenes with hexafluoroisopsropylidene diphthalic anhydride.
