Fate of Photo-Excited Molecular Antennae – Inter-Molecular Energy Transfer versus Photodegradation Assessed by Quantum Dynamics

The present computational study aims to unravel the competitive photo-induced inter-molecular energy transfer and electron transfer phenomena in a light-harvesting antenna with potential applications in...

Acetoxymethyl (AM) Concept for Intracellular Administration of Carbon Monoxide with Mn(CO)3-Based photoCORMs

Targeted administration of carbon monoxide with CO releasing molecules (CORMs) inside of cells proved to be very challenging. Consequently, there are only very few reports on intracellular uptake of CORMs...

Unusually Short-Lived Solvent-Dependent Excited State in a Half-Sandwich Ru(II) Complexe Induced by Low-Lying 3MC States

A ruthenium complex with a half-sandwich geometry ([(p-cymene) Ru (Cl) (curcuminoid)]) was synthesized, character-ized and investigated regarding its ultrafast photophysics. These photophysical investigations...

Cryogenic Current Comparators for larger beamlines

The new version of a Cryogenic Current Comparator with eXtended Dimensions (CCC-XD) for the beam monitoring of charged particles was built and is currently being optimized. The CCC-XD is designed for a...

Advanced HTS dc SQUIDs with step-edge Josephson junctions for geophysical applications

For ground-based electromagnetic methods in geophysics, dc Superconducting Quantum Interference Devices based of high temperature superconductors are well suited as magnetic field sensors. Therefore, we...

Interfacing optical fibers with plasmonic nanoconcentrators

The concentration of light to deep-subwavelength dimensions plays a key role in nanophotonics and has the potential to bring major breakthroughs in fields demanding to understand and initiate interaction...

Effectively single-mode self-recovering ultrafast-nonlinear nanowire surface plasmons

We report on a regime for surface-plasmon propagation, which is robust to defects and effectively single mode, and we exploit it for accessing the ultrafast nonlinear response of gold on centimeter-long...
