Regenerated Bragg gratings in Panda fibres for simultaneous temperature and force measurements at high temperatures

Simultaneous temperature and force measurements in an extended temperature range up to 500°C were shown with a regenerated fibre Bragg grating in a polarisation maintaining fibre of type Panda. Type I...

Spectroscopy of a superconducting flux qubit in a quasidispersive mode

The properties of a superconducting flux quantum bit (qubit) in the quasidispersive mode, where the frequency of a probe signal is lower than the qubit excitation frequency but is close to it, have been...

A microwave cryogenic low-noise amplifier based on sige heterostructures

A low-noise cryogenic amplifier for the measurement of weak microwave signals at sub-Kelvin temperatures is constructed. The amplifier has five stages based on SiGe bipolar heterostructure transistors...

Josephson systems based on ballistic point contacts between single-band and multi-band superconductors

The Josephson effect in ballistic point contacts between single-band and multi-band superconductors was investigated. It was found that in the case of Josephson junctions formed by a single-band and an...

A shifted-excitation Raman difference spectroscopy (SERDS) evaluation strategy for the efficient isolation of Raman spectra from extreme fluorescence interference

A biochemical characterization of pathologies in biological tissue can be provided by Raman spectroscopy. Often, the raw spectrumis severely affected by fluorescence interference. We report and compare...

Optimized green fluorescent protein fused to FoF1-ATP synthase for single-molecule FRET using a fast anti-Brownian electrokinetic trap

Observation times of freely diffusing single molecules in solution are limited by the photophysics of the attached fluorescence markers and by a small observation volume in the femtolitre range that is...

Printed circuit boards as platform for disposable lab-on-a-chip applications

An increasing demand in performance from electronic devices has resulted in continuous shrinking of electronic components. This shrinkage has demanded that the primary integration platform, the printed...

Ruthenium tris-diimine complexes displaying acridine-based -extended ligands: efficient functionalization through a “chemistry on the complex” strategy

Tip-Enhanced Raman Scattering Reveals Heterogeneity of Secondary Structures in Amyloid Fibrils Formed by Peptide CGNNQQNY

Tip-enhanced Raman Scattering (TERS) is an advanced technique allowing to measure Raman signals with high spatial resolution. By utilizing SERS effect in a probe coupled with Scanning Probe Microscopy...

100 W average power femtosecond laser at 343 nm

We present a femtosecond laser system delivering up to 100 W of average power at 343 nm. The laser system employs an Yb-based femtosecond fiber laser and subsequent second- and third-harmonic generation...
