Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy

Advanced 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.

Continuously tunable narrow-linewidth fiber lasers

, 2020
Narrow linewidth tunable fiber lasers have become an important tool in research and in-field applications thanks to their high beam quality, great spectral performance, compact structure and environmental robustness. Many methods have been introduced and developed throughout decades to fulfill the need for rapid wavelength adjustment of these fiber ...

Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Symmetric Metal Organic Framework‐Plasmonic Architectures for Reversible and High‐Sensitivity Optical Sensing

Small, EarlyView.
This work presents a plasmonic sensing platform combining surface lattice resonances (SLRs) in 2D metal nanoparticle gratings with ZIF‐8 MOF films. The plasmonic grating is easily and scalably produced from template‐assisted assembly of metal colloids, which is fully compatible with MOF growth. The resulting MOF‐plasmonic structure allows for a dynamic

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

Small, EarlyView.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Versatile High‐Sensitivity EPR Using Superconducting Spiral Microresonators

Small Methods, EarlyView.
A significant sensitivity enhancement in conventional X‐band pulsed EPR is achieved using planar spiral microresonators fabricated from high‐temperature superconducting YBCO. Fully compatible with standard instrumentation, the approach enables high‐fidelity spin control under typical sample conditions.

Large‐Scale Synthesis of InP/ZnS Quantum Dots Using Continuous Flow Chemistry

Small Structures, EarlyView.
Novel precursors for the continuous flow synthesis of highly luminescent InP/ZnS core/shell QDs are identified, enabling their fully automated gram‐scale production in a two‐stage process. The developed synthetic approach employs hazard‐free aminophosphine chemistry in a noncoordinating solvent.

Matrix‐Isolation Electron Paramagnetic Resonance Studies of Radical Ions and Neutral Radicals Generated by Radiolysis of Organic Molecules at Cryogenic Temperatures

The Chemical Record, EarlyView.
By selecting an appropriate matrix and irradiating the matrix containing a trace amount of solute at low temperatures, ionic or neutral radicals derived from the solute can be generated and trapped in the matrix. EPR spectroscopy of these samples yields highly detailed information on the radicals, inaccessible by other experimental techniques. Electron

Comparative evaluation of noncanonical amino acids as site‐specific NMR probes for the complex of E. coli SSB with single‐stranded DNA without isotope labelling

The FEBS Journal, EarlyView.
Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.
