Unlocking synergistic benefits of the calcium looping-calcium hydroxide integration for energy storage: A perspective on sorbent performance

Calcium Looping has recently attracted attention as a high temperature thermochemical energy storage system. However, significant sintering due to the high temperatures hampers the recyclability of CaO. Hydration and hydroxylation has been explored as a method to regenerate the spent CaO. This study investigates a novel synergistic integration of carbonation (CaCO3/CaO) and hydroxylation (CaO/Ca(OH)2) reactions.…

Quantification of Emission Efficiency in Persistent Luminescent Materials

Accurate quantification of efficiency enables rigorous comparison between different photoluminescent materials, providing an optimization path critical to the development of next-generation light sources. Persistent luminescent materials exhibit delayed and long-lasting luminescence due to the temporary storage of optical energy in engineered structural defects. Standard characterization methods do not provide a universal comparison of phosphor performance,…

Fine-grained BCZT piezoelectric ceramics by combining high-energy mechanochemical synthesis and hot-press sintering

Different stoichiometries of lead-free BaZr0.2Ti0.8O3-Ba0.7Ca0.3TiO3 (BCZT) prepared by mechanosynthesis and sintered by either conventional sintering (CS) or hot pressing (HP) techniques were studied to establish the dependence of piezoelectric and dielectric properties on sintering parameters and microstructure. All synthesized stoichiometries showed a pseudocubic perovskite phase with homogeneously distributed A- and B-cations in the structure. The…

Topotactic Reduction-Induced Stabilization of β-La2Mo2O8.68 Phase: Structure, Static Oxygen Disorder, and Electrical Properties

La2Mo2O9 is acknowledged as an exceptional oxide ion conductor. It undergoes a reversible phase transition around 580 degrees C from the nonconductive low-temperature monoclinic alpha-La2Mo2O9 phase to the highly conductive high-temperature cubic beta-La2Mo2O9 phase. In addition, La2Mo2O9 demonstrates complex chemistry under reducing conditions. This study reports, for the first time, the stabilization at ambient temperature…

Better together: Monolithic halide perovskite@metal-organic framework composites

The instability and limited scalability of halide perovskites hinder their long-term viability in applications as X-ray detectors. Here, we introduce a sol-gel ship-in-bottle approach to produce a monolithic perovskite@metal-organic framework (MOF) composite, combining the properties of the individual building blocks and enhancing density, robustness, and stability. By tuning seed particles below 100 nm, we achieve highly crystalline,…
