Extending Field Limits in Nanoscale Magnetic Imaging With Metamaterial‐Inspired Magnetic Flux Concentrators

Small, EarlyView.
Micrometer‐sized flower‐shaped metamaterial magnetic flux concentrators are fabricated directly around nano and micromagnetic samples, enabling local field enhancement. Integrated into magnetic sensitive photoemission electron microscopy, they extend the available magnetic field range by up to a factor of five.

High‐Entropy Interfacial Optimized 3D Nano‐Collector Enables Dendrite‐Free and Ultra‐Stable Lithium Metal Batteries

SusMat, EarlyView.
By integrating a MnNiVCrFe HEA interphase with a 3D NF scaffold, this 3D current collector homogenizes the interfacial electric field and Li+ distribution. This synergistic interphase–structure modification strategy enables uniform lithium nucleation and deposition, thereby suppressing dendrite formation and boosting interfacial stability. Consequently,

Ionothermal Synthesis of Cu(Sb2Se3)[AlCl4] and Cu5(Bi2Se3)6[AlCl4]5 : Monolayers of Sb2Se3 and Bi2Se3 Stabilized by Cu[AlCl4]

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Ionothermal synthesis in Lewis‐acidic ionic liquids (ILs) yields two new low‐dimensional pnictogen–selenide networks cocrystallized with Cu[AlCl4]. Both are narrow‐gap semiconductors that exhibit strong absorption throughout the visible range. Topochemical AlCl3 extraction triggers partial delamination, pointing to a viable route toward 2D derivatives.

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

High Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

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 ...
