Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy

open access: yesAdvanced Quantum Technologies, EarlyView.
A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.

Autocorrelation analysis for the unbiased determination of power-law exponents in single-quantum-dot blinking

open access: yes, 2014
We present an unbiased and robust analysis method for power-law blinking statistics in the photoluminescence of single nano-emitters, allowing us to extract both the bright- and dark-state power-law exponents from the emitters' intensity autocorrelation ...

Calorimetric consequences of thermal softening in Johnson–Cook’s model [PDF]

open access: yes, 2013
At high loading rates, the development of adiabatic shear bands in metals is conventionally attributed to the strong interactions induced by viscoplastic dissipation within the bands and thermal softening effects.

Acid Resistant and Highly Silver Selective Membranes Based on Charged Nanoporous 2D‐Materials

open access: yesSmall, EarlyView.
In this work, new membranes based on charged & nanoporous nanosheets with unprecedented selectivity to silver versus a wide range of other metallic ions are reported. Furthermore, a demonstrated and lead specific intralamellar lead pathway is demonstrated. A potential applicability for ubiquitous silver in WEEE is validated.

Characterization of the Plasma Shape of the TIG Welding Arc [PDF]

open access: yes, 2006
Tungsten electrodes were prepared to analyse the plasma geometry at TIG welding. The investigated electrodes were La02, Th02 alloyed. Tip flatted electrodes were grinded as well. The shape of plasma were analysed for 36 different electrodes.
