Noncatalytic Synthesis of High‐Density and Small‐Diameter WS2 Nanotubes

National Materials, EarlyView.
A noncatalytic strategy enables high‐density WO₂.₉ nanowire synthesis on engineered substrates. Subsequent sulfuration converts them into small‐diameter WS₂ nanotubes. Individual nanotube devices show superior photoresponse, highlighting a scalable route for optoelectronics.

Fingerprinting Superconductors by Disentangling Andreev and Quasiparticle Currents Across Tunable Tunnel Junctions

Small, EarlyView.
Tunneling Andreev reflection spectroscopy leverages the exponential sensitivity of tunneling current to distinguish between a variety of superconducitng order parameters. Here it is shown that the additivity of excess decay rate enables clear separation of Andreev and quasiparticle currents, fingerprinting the existence of sign changing superconducting

Achieving Large Uniaxial and Homogeneous Strain in Two‐Dimensional Materials

Small, EarlyView.
Strain is a powerful tool for tuning the electronic, magnetic, and topological properties of 2D materials ‐ particularly at high values (>3$>3$%) where many electronic and structural transitions are predicted. Our high‐yield preparation and device strain platform overcomes existing strain limitations (often <1.5$<1.5$%), enabling repeatable and ...

Ionic Liquids at the Interface With the Transition Metal Dichalcogenide MoS2: Effect of the Chemical Structure on Induced Charge Carrier Density

Small, EarlyView.
Ionic liquid gating of MoS2 channels using [EMIM][TFSI] or [EMIM][BF4] can lead to different carrier densities. [TFSI]‐based systems exhibit steeper voltage decay (compared to [BF4]‐based systems) meaning the potential drops more rapidly across the electric double layer, indicating stronger local electric fields and more efficient charge accumulation ...

Magnetic Structure of the High‐TN Antiferromagnet La0.5Sr3.5Fe3O7.5F2.6: A Temperature‐Dependent Mößbauer Spectroscopy and Neutron Diffraction Study

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.

An Overview of High‐Temperature Superconducting Cables in DC Systems: Unlocking Potential for High‐Voltage DC Networks

High Voltage, EarlyView.
ABSTRACT This paper provides an overview of high‐temperature superconducting (HTS) cables in DC systems, with a focus on their deployment in high‐voltage DC (HVDC) networks. The assessment of HTS cable properties—such as extremely low electrical resistance, high current‐carrying capacity and a compact geometry—and their comparison with those of ...
