Summary: Solid oxide fuel cells (SOFCs) are attractive energy conversion devices due to their fuel flexibility, environmental friendliness, and promising energy conversion efficiency. However, the high operating temperature of SOFCs poses challenges in stability, sealing integrity, and safety. Lowering the operating temperature to 600°C or lower is an important research topic. Magnetron sputtering is gaining attention as a thin-film preparation technology for electrolyte thin films with high stability and performance at lower temperatures. This comprehensive review analyzes various electrolyte preparation methods, focusing on magnetron sputtering technology for oxygen-ion conducting electrolyte thin films. The effects of processing parameters on the microstructures and properties of the thin films, as well as the relevant interfaces and full SOFCs, are discussed. Perspectives and directions for developing high-performance SOFCs with thin-film electrolytes prepared by magnetron sputtering technology are presented.

Summary: A single-step wet-chemical synthesis method for NiO-SDC colloidal ink has been developed for inkjet printing of nanostructured anodic layers with enhanced catalytic activity in solid oxide fuel cells (SOFCs). The ink solution contains stable nanoparticles with a main size of 11.85 nm, which leads to a significant reduction in the area-specific resistance of the inkjet-printed half-cell. The microstructure engineering using inkjet printing results in a cermet layer with enhanced catalytic activity for SOFCs.

Summary: This study theoretically analyzes the effects of different shapes of corrugated electrolytes on the performance of solid oxide fuel cells (SOFCs). By modifying the mesoscale electrode-electrolyte interface, corrugated electrolytes with various shapes are applied to conventional anode-supported planar SOFCs. Three-dimensional models of SOFCs with different shapes of corrugated electrolytes are developed, and the influence of the corrugated electrolytes on cell performance is analyzed. The results show that the corrugated electrolyte structure reduces local exchange current density but increases overall charge transfer, leading to improved cell performance. The improvement in performance is proportional to the degree of area expansion of the corrugated electrolyte.

Summary: Bi2O3 is a promising sintering additive for YSZ that can decrease its sintering temperature and increase its ionic conductivity. However, the growth of Bi2O3 into large-sized rods and its addition inducing phase instability and precipitation of monoclinic ZrO2 are unfavorable for the electrical property. A microemulsion method was introduced to control the morphology and size of Bi2O3. Spherical Bi2O3 nanoparticles were obtained and nanosized Bi2O3-YSZ composite powders with good mixing uniformity dramatically decreased the sintering temperature and increased the conductivity of YSZ electrolytes.

Summary: By using shortcuts to adiabatic (STA) method, a fast multi-photon down-conversion can be implemented, rapidly creating 2N photons from the quantum vacuum based on the counter-rotating effect of an ultrastrong light-matter coupling. The energy for the produced photons is provided by a high-frequency pump field. The STA method is employed to design the driving fields that induce rapid population transfer, enabling the generation of Fock states from vacuum with high fidelities while mitigating the influence of decoherence.

Summary: Laser protective materials are in high demand due to the rapid development of laser technology. This study developed ZrC/PBI composites with added short carbon fiber (SCF) using solution impregnation and hot-press molding. The composites exhibited improved ablation and mechanical properties and showed no burn-through, peeling, or splitting during high-energy continuous laser ablation. Increasing the ZrC content in the composites led to the formation of dense oxide layers, enhancing their ablation properties. The composite with a ZrC/PBI mass ratio of 2:1 showed the lowest mass loss, mass ablation rate, and linear ablation rate, making it suitable for high-energy continuous laser applications.

Summary: For perovskite manganites, achieving low-field colossal magnetoresistance (CMR) is crucial. In this study, the magnetic field driven insulator-to-metal transition in La1-x-yPrxCayMnO3 is investigated using real space magnetic force microscopy (MFM). Three stages of the phase transition are observed, with distinct features in domain nucleation and growth. MFM reveals that domain growth requires a lower field than domain nucleation, providing critical information for achieving low-field CMR.

Summary: In this article, the authors proposed the use of Weibull regression model with gamma random effects for statistical inference of ALT data with blocking, deviating from the previous assumption of normal distribution. Maximum likelihood estimation and Bayesian estimation methods were applied to estimate the unknown parameters in the proposed model. The proposed methods were illustrated using real data examples and simulation examples. Numerical results showed that the distribution of random effects had minimal impact on the estimation of fixed effects in the Weibull regression models. Furthermore, methods to compare ALT plans and identify the optimal ALT plans were provided to demonstrate the advantage of the proposed model.

Summary: In this study, the emergence of spin-chirality-driven quantum anomalous Hall effect (QAHE) and quantum topological Hall effect (QTHE) is demonstrated by sandwiching a 2D Z(2) topological insulator between two chiral kagome antiferromagnetic single-layers. The QAHE is realized with fully compensated noncollinear antiferromagnetism instead of conventional collinear ferromagnetism. The Chern number can be regulated periodically with the interplay between vector- and scalar-spin chiralities, and the QAHE can even occur without spin-orbit coupling, indicating the rare QTHE. These findings open up a new avenue for antiferromagnetic quantum spintronics based on unconventional mechanisms from chiral spin textures.

Summary: Room temperature grown Fe monolayer on the Ir(111) single crystal substrate can form nano-skyrmion lattice under proper growth conditions. However, the formation of nanoscale skyrmions is greatly influenced by the diffusion length of Fe adatoms on the Ir(111) surface. The impurity density on the substrate surface determines the size and shape of Fe islands, which in turn affects the formation of skyrmion lattice.

Summary: In this study, TiO2 was added to silica aerogel in three different ways to enhance its resistance against high-energy lasers. Direct deposition of TiO2 nanoparticles was found to achieve the best laser resistance synergistic effect with silica aerogel. The TiO2-silica composite aerogel showed no signs of breakdown within 2 min of continuous-wave laser irradiation. By changing the amount of TiO2 added, the general trend of this synergistic effect was obtained, extending the mathematical model maximum energy transfer radius (METR) and advancing the application of this material in high energy laser protection.

Summary: Magnetic ultrathin films grown on heavy metal substrates can exhibit rich spin structures due to various magnetic interactions. In this study, magnetic nanoskyrmion phases in Fe monolayers grown on Ir(111) substrates were studied using spin-polarized scanning tunneling microscopy. The formation of nanoskyrmion lattices in the Fe/Ir(111) system depends on the growth conditions, and nonskyrmion spin states can also be formed. By applying voltage pulses, a phase transition from nonskyrmion to skyrmion was observed, determined by the total injected energy during the pulse. The creation of nanoscale skyrmion lattices is important for designing skyrmion-based spintronic devices.

Summary: This study explores the possibility of electrically manipulating domain wall (DW) using the DW bound states in magnetic Weyl semimetal EuB6. By combining magnetic force microscopy (MFM) and first-principles calculations, it is found that domains with magnetization aligned along the [100] directions dominate under a certain magnetic field. The calculated DW bound state shows a spectral distribution over a large portion of the DW Brillouin zone. The localized charges generated by these DW bound states can be used to drive DW motion through electrostatic forces.

Summary: The beauty of the quantum Hall effect lies in the metrological precision of Hall resistance quantization, which is derived from topological edge states. In this study, we investigate the relationship between quantization breakdown and edge states in the MnBi2Te4 system using conventional transport and real space conductivity mapping. Our experimental results demonstrate the existence of topological edge states during quantization breakdown, which can cause the breakdown due to their dissipative and diffusive nature.
