High‐Throughput Single‐Nanowire Optoelectronic Characterization Using Microfluidic Technology

Advanced Photonics Research, EarlyView.
An ultrathin microfluidic platform enables high‐throughput, in‐line single particle characterization of semiconductor nanowires. Using correlative spectroscopy and imaging, analysis at 240 nanowires per minute, uncovering previously hidden details about intra‐wire disorder and inter‐wire inhomogeneity, is achieved.

A Sky Full of Stars, Constellations, Satellites and More! Legal Issues for a ‘Darkʼ Sky

Oslo Law Review
An ever-increasing number of actors, including private entities, are conducting space activities that involve the launch of spacecraft into orbit. The ‘miniaturisationʼ of technology has meant that this now includes the launch of large constellations of ...

Self‐Detecting Mid‐Infrared Dual‐Comb Spectroscopy Based on High‐Speed Injection‐Locked Quantum Cascade Lasers

Advanced Photonics Research, EarlyView.
A compact self‐detecting dual‐comb spectroscopy (DCS) system based on dispersion‐engineered, high‐speed packaged quantum cascade lasers (QCLs) at λ≈4.6 μm under coherent injection locking is demonstrated. Broad multiheterodyne comb signal with reduced tooth linewidths by orders of magnitude is recorded.

Enhanced Oxygen Evolution Reaction Performance of Niobium–Cobalt Oxide Catalysts in Acidic and Alkaline Media

Advanced Sustainable Systems, EarlyView.
The electronic modulation of Nb‐doped Co3O4 catalyst showcases enhanced activity and extended stability for OER in both alkaline (1M KOH) and acidic (0.5M H2SO4) electrolytes. The higher activity emanated from the synergistic effect between the Nb5+ dopant and Co3O4.

Correlations in Magnetic Sub‐Domains as an Unconventional Phase Diagram for van der Waals Ferromagnets

Advanced Science, EarlyView.
An unconventional magnetic order is observed in exfoliated CrBr3 layers, characterized by vertically correlated planar magnetic sub‐domains. Magnetic force microscopy, ab initio calculations, and micromagnetic simulations indicate that these sub‐domains arise from stacking faults modifying interlayer exchange coupling.
