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...

Carrier lifetime in liquid-phase crystallized silicon on glass

Liquid-phase crystallized silicon on glass (LPCSG) presents a promising material to fabricate high quality silicon thin films, e.g. for solar cells and modules. On the glass substrate at first barrier...

High-power fiber laser based on a non filamented-core fully-aperiodic large pitch fiber

In this communication, the authors report on the first high power emission obtained using a solid non-filamented core fully-aperiodic large pitch fiber manufactured by the REPUSIL method which is based...

Dehydration of 3-octanol studied by 2D Raman, IR and NMR hetero correlation spectroscopy

2D correlation spectroscopy is a useful technique for analyzing chemical reactions. We studied the acid catalyzed dehydration of 3 - octanol at 150 °C with FT Raman, FT ATR IR and 1H NMR and evaluated...

Characterization of an on-chip magnetic shielding technique for improving SFQ circuit performance

An on-chip magnetic shielding technique was characterized on several DC-SQUIDs to prepare the next generation of complex digital RSFQ circuits designed by the FLUXONICS foundry. The maximal frequency of...

Surface-enhanced Raman spectroscopy (SERS) in food analytics: Detection of vitamins B2 and B12 in cereals

Food analysis has been gaining interest throughout recent decades for different reasons: the detection of hazardous substances in food and routine investigations of food composition and vitamin/nutrient...
