Catalytically Enhanced Near Room‐Temperature Hydrogen Sensing Using Pd‐ZnO Colloidal Crystals
Pd‐decorated ZnO colloidal crystal monolayers demonstrate excellent performance across a wide hydrogen concentration range at 33°C, with high selectivity and reproducible device fabrication. The sensors show strong responses even at low‐ppm H2 concentrations and an ultra‐low detection limit of 82 ppb, indicating their suitability for diverse hydrogen ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

From Molecular Design to Optical Anisotropy: Orientation Control in BODIPY Langmuir‐Blodgett Films
The supramolecular organization of amphiphilic boron‐dipyrromethene (BODIPY) dyes in Langmuir–Blodgett monolayers is shown to govern their optical anisotropy. By correlating nanoscale imaging and angle‐resolved spectroscopy, we reveal symmetry‐driven control of transition dipole orientation, enabling either in‐plane or out‐of‐plane optical responses ...

Microstructural Considerations on the Magnetostriction Enhancement in Dy Doped Fe81Al19 Alloys
Dy additions induce significant microstructural modifications in Fe–Al alloys, evolving from Dy‐rich agglomerates to columnar grains that promote preferential orientation, particularly along the (200) plane. These changes reduce microstrains and modify crystallite shape, leading to enhanced magnetostriction.

Facet‐engineered BiSI nanorods for intelligent distinguishing detection of NO2/H2S mixed gas
Mixed toxic gases such as NO2 and H2S can threaten safety in coal mines and industrial settings, but it is still difficult to monitor them accurately with a simple sensor. In this work, we improved a BiSI‐based room‐temperature gas sensor through crystal facet engineering and combined it with machine learning so that one sensor could distinguish mixed ...

Reflectance anisotropy and Raman scattering spectroscopy studies of ZnSe grown on GaAs(001)
Using an evaporation chamber equipped with a ZnSe compound source, we have grown ZnSe on GaAs(001) and characterized the surface using low-energy electron diffraction (LEED), Raman scattering spectroscopy and reflectance anisotropy spectroscopy (RAS ...

Fast 23Na MRI of the human calf at 7T was achieved by reducing nominal spatial resolution. Shorter measurement times can improve clinical feasibility of 23Na MRI while preserving reliable quantification of apparent tissue sodium concentration through partial volume, relaxation, and B0/B1 corrections.
