Summary: 2D lead halide perovskites with tunable bandgap and enhanced chemical stability are useful for designing optoelectronic devices. Reducing dimensionality can increase resistance to light-induced ion migration, but also decreases the efficiency of halide ion segregation and segregation rate constant, leading to a decrease in charge-carrier lifetime.

Summary: Time-domain study of coherent acoustic phonons in nanomaterials provides dynamic and unparalleled insight into their mechanical and structural features. The acoustic breathing mode of resonant coherent phonons (RCP) in nanoscale RP perovskite films is reported, which shows that RCP oscillation can be used as a novel and non-destructive approach for quantitatively evaluating the decomposition of moisture-exposed RP perovskite. These results reveal the decisive effect of structural geometry on acoustic performances in perovskite nanomaterials.

Summary: Ruddlesden-Popper (RP) tin-based halide perovskites have attracted attention due to their low-toxicity and low-cost processability. This study proposes a method to slow down crystallization kinetics in RP tin-based perovskites by regulating intra- and intermolecular interactions. By introducing an electron-rich heterocyclic thiophene into bulky spacers, the intermolecular interaction is decreased and intramolecular interactions are increased, leading to the stabilization of colloids and orderly crystal growth. The perovskite solar cell using this method demonstrates a two-fold improvement in power conversion efficiency compared to the control sample.

Summary: Designing an efficient cathode and accelerating the sluggish oxygen reduction reaction process are crucial for enhancing electrochemical outputs in solid oxide fuel cells (SOFCs). A novel multifunction layer cathode, combining a Gd0.2Ce0.8O2-delta (GDC) interlayer with a La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) cathode functional layer, is reported in this study. By precisely controlling the concentration of the infiltration precursor solution, discrete and filmy LSCF coatings on the GDC scaffold can be prepared, with the film-like coating exhibiting lower initial polarization impedance and better stability. The as-obtained SOFCs exhibit enhanced peak power density and long-term operation stability.

Summary: Two Co-alloy-coated steels with different manganese contents underwent thermal exposure in air for 1000 hours. The oxidation rate of the coated steels increased with higher manganese content. The Co coating transformed into a three-layer structure during thermal exposure, containing Cr-rich oxide, mixed oxide with Co, Fe, Mn, and Cr, and doped Co3O4 spinel oxide. The Co-coated steel with 1.0 wt% Mn showed lower area specific resistance and slower increase in polarization resistance compared to the uncoated alloy, indicating effective inhibition of outward diffusion of Cr and prevention of cathode poisoning.

Summary: In this study, metallic Co composite coatings with CeO2, La2O3, and Y2O3 reactive element oxides were prepared on Fe-17Cr alloys by electroplating for solid oxide fuel cell interconnect applications, followed by cyclic oxidation. The results showed that all three composite coatings significantly enhanced the oxidation resistance of the substrate alloy at high temperatures, with no further migration of chromium in the coating region. Among the three coatings, the Co/CeO2 coating showed the best performance after 500 hours of oxidation, exhibiting the slowest oxidation rate and the lowest area specific resistance.
