Controlled Synthesis and Enhanced Photocatalytic Performance of MgAl2O4 Spinel Nanopowders for Environmental Applications

ChemistryOpen, Volume 15, Issue 8, August 2026.
A simple solid‐state route was employed to synthesize MgAl2O4 spinel nanopowders with high photocatalytic efficiency. The obtained nanomaterial achieved 95% degradation of Rhodamine B under Xe lamp irradiation, demonstrating its potential as an efficient photocatalyst for wastewater purification. Nanopowders of magnesium aluminate spinel (MgAl2O4) were

NiO Dissolution in Molten Carbonate Fuel Cell Cathodes: Challenges and Strategies for Long‐Term Stability

ChemElectroChem, Volume 13, Issue 13, 2 July 2026.
Molten carbonate fuel cells (MCFCs) enable efficient power generation and CO2 capture but suffer from nickel oxide (NiO) cathode dissolution, which limits lifetime. This review summarizes strategies to mitigate NiO degradation, including coatings, doping, alternative cathode materials, and electrolyte modification.

ZrTiO4 Nanowire Growth Using Membrane-assisted Pechini Route

Orbital: The Electronic Journal of Chemistry, 2016
The high surface-to-volume ratio of nanowires makes them natural competitors as newer device components. In this regard, a current major challenge is to produce quasi-one-dimensional nanostructures composed of well-established oxide-based materials. This

Bridging Boltzmann and Non‐Boltzmann Optical Thermometry Enabled by Multimodal Perovskite Nanocrystals

Advanced Optical Materials, Volume 14, Issue 26, 10 July 2026.
Multimodal perovskite nanocrystals enable optical thermometry across multiple excitation and emission regimes, spanning the UV–Vis–NIR spectral range. By combining upconversion, downshifting, and persistent luminescence, the platform bridges conventional Boltzmann and non‐Boltzmann thermometric approaches.

Photo‐Electrocatalytic Activity and Photo‐Induced Charge Storage of a CeO2/Ce(TeO3)2 Composite Photo‐Anode for the Visible‐Light‐Driven Oxygen Evolution Reaction (OER) in KOH, NaOH, and LiOH

Nano Select, Volume 7, Issue 7, July 2026.
For the CeO2/CeTe2O6 composite, synthesized through the sol–gel technique and subsequent calcination at 800°C, the oxygen evolution reaction is the most active in a KOH electrolyte (CeTO‐800), compared to NaOH and LiOH, for both illuminated (PEC) and post‐Illuminated (OFF) samples.
