Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.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

Mott–Schottky Analysis of Archaeological Etruscan Pottery
ElectroanalysisThe application of Mott–Schottky (MS) analysis to electrochemical impedance data recorded for microparticulate deposits of archaeological ceramic materials is described. Upon attachment to paraffin‐impregnated graphite electrodes in contact with aqueous acetate buffer at pH 4.75, impedance data in potential ranges with and without the occurrence of ...

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.
