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...

Carbon chloride-core fibers for soliton mediated supercontinuum generation

We report on soliton-fission mediated infrared supercontinuum generation in liquid core step-index fibers using highly transparent carbon chlorides (CCl4, C2Cl4). By developing models for the refractive...

An “in-fiber” Whispering-Gallery-Mode bi-sphere resonator, sensitive to nanometric displacements

A double-cavity, Whispering-Gallery-Mode (WGM) resonator, composed of two polystyrene microspheres, is formed inside the capillary of a microstructured optical fiber. The spectra are compared with the...

Fabrication of self-assembled spherical Gold Particles by pulsed UV Laser Treatment

We report on the fabrication of spherical Au spheres by pulsed laser treatment using a KrF excimer laser (248 nm, 25 ns) under ambient conditions as a fast and high throughput fabri-cation technique. The...

Cryogenic time domain multiplexer based on SQUID arrays and superconducting/normal conducting switches

Analysis of basidiomycete pigments in situ by Raman spectroscopy

Basidiomycetes, i.e., mushroom-type fungi, are known to produce pigments in response to environmental impacts. As anti-oxidants with a high level of unsaturation, these compounds can neutralize highly...
