Summary: A study was conducted on the structural properties of RBaMn2O6 (R = La, Pr, and Nd) compounds using synchrotron radiation x-ray powder diffraction and Raman spectroscopy. Results showed that LaBaMn2O6 exhibited a ferromagnetic transition at low temperatures, while PrBaMn2O6 and NdBaMn2O6 displayed structural transitions coupled with an antiferromagnetic transition. The low-temperature phases of PrBaMn2O6 and NdBaMn2O6 were found to be orthorhombic, with unique symmetry properties revealed by Raman spectroscopy.

Summary: The study found that the residual stresses on the outer surface of the dense yttria-stabilized zirconia (YSZ) layer were compressive, increased with decreasing temperature, and exhibited nonlinear temperature dependence, particularly below 600 degrees C. An elastic model incorporating micromechanics and laminate theory successfully predicted this nonlinearity, considering the order-disorder transition of YSZ around 600 degrees C and the magnetic transition of NiO at the Neel temperature around 265 degrees C. The implications of these findings for the reliability of solid oxide fuel cells are discussed.

Summary: Macroscopic descriptions of ferroelectrics have limitations in terms of predicting materials parameters from microscopic structures. This study establishes a two-way mapping between spatially inhomogeneous fields and discrete lattice modes, enabling a natural treatment of gradient couplings in the macroscopic regime. The findings reveal a generalized translational covariance in the continuum description of inhomogeneous ferroelectric structures, canceling out the inherent arbitrariness in flexoelectric and polarization gradient coefficients.

Summary: This research focuses on a Ni-Mg-Al hydrotalcite-derived catalyst promoted with Cu for CO2 hydrogenation to methane. The Cu promotion was especially effective at low temperatures, leading to significant CO2 conversion and selectivity for methane formation. Higher Cu content did not necessarily result in better activity, as high Cu concentrations were found not to be suitable for CO2 methanation. Additionally, the formation of Ni-Cu solid solution and subsequent redispersion of Ni-Cu alloy during the methanation reaction were observed.

Summary: A novel SBMCo electrode, consisting of exsolved metallic cobalt for the anode and cobalt oxide for the cathode, is elaborately designed for symmetrical solid oxide fuel cells (SSOFCs). The results show that the rate-limiting steps for hydrogen oxidation at the anode and oxygen reduction at the cathode are significantly promoted by the exsolved nanoparticles on the SBMCo backbone, allowing the electrodes to exhibit remarkable catalytic activity.

Summary: The research aims to explain the differences between nominal and actual chemical compositions of silicate-phosphate glasses in the SiO2-P2O5-K2O-MgO-SO3 system. X-ray fluorescence (XRF) analyses were used to determine the actual compositions. Changes in the chemical composition were studied through differential scanning calorimetry-thermogravimetry-related gas analysis by mass spectrometry (DSC-TG-EGA (MS)) and high-temperature X-ray diffraction (HT-XRD). The release of gaseous products was found to be associated with changes in the chemical composition of sulfur-bearing glasses. Water vapor, carbon dioxide, carbon monoxide, and ammonia were the main gases released during thermal decomposition. Considering the potential use of these glasses as glassy fertilizers, this study is important from an environmental perspective.

Summary: An efficient surface modification strategy was proposed to significantly increase the initial Coulombic efficiency (ICE) of SiO anode material. SiO@Fe material with Fe nanoclusters decorating the SiO surface was successfully prepared. The well-dispersed Fe nanoclusters realized an Ohmic contact with lithium silicates, reducing electron conduction barriers and promoting lithium-ion release, leading to higher ICE of the SiO anode. The prepared SiO@Fe exhibited an unprecedented increase in ICE (23%) compared to pristine SiO, and showed improved cycling and rate performance.

Summary: The local crystal structure of Y3NbO7 was investigated using neutron total scattering. Five different structural models were tested, and only the monoclinic weberite model provided a good fit to the experimental data. The monoclinic weberite structure features distorted YO8 dodecahedra, YO7 monocapped octahedra, and NbO6 octahedra, and could be used as a starting point for modeling fluorite-based materials with challenging local structures.

Summary: The A-site cation-ordered GdBa(0.5)Sr(0.5)Co(2-x)Cu(x)O(5+δ) (GBSCC) double perovskites were evaluated as high-performance oxygen electrodes for reversible solid oxide cells (rSOCs). By substituting copper for toxic and expensive cobalt, the aim was to minimize the cobalt content while improving or maintaining the required thermomechanical and electrocatalytic properties. The study found that compositions with 1 ≤ x ≤ 1.15 were particularly interesting, exhibiting decreased thermal and chemical expansions and sufficient transport properties. The GdBa0.5Sr0.5Co0.9Cu1.1O5+δ oxygen electrode showed promising results with low electrode polarization resistance values and high power outputs, making it suitable for rSOCs.

Summary: Co-free REBa2Cu3O6+ẟ (RE= La, Nd, Sm, Gd and Y) triple perovskite ceramics were studied as cathodes for intermediate-temperature solid oxide fuel cells. The orthorhombic to tetragonal phase transition and its relation with electrochemical performance were investigated. The results indicate that an oxygen diffusion/incorporation co-limited process is the rate-limiting step of the oxygen reduction reaction (ORR). A clear correlation is observed between the power density and ionic radii of the RE cation of these triple perovskites.

Summary: High-entropy (La,Pr,Nd,Sm,Gd)BaCo2O5+delta double perovskite-type oxide with an equimolar, high-entropy, A-site-layered arrangement of cations was successfully synthesized. The material exhibited excellent phase stability and thermal expansion behavior, high electrical conductivity, and equilibrium oxygen content. The cathode material showed low polarization resistance and high power density in a fuel cell. However, the influence of the high-entropy A-site arrangement was relatively limited compared to conventional analogs.

Summary: An efficient method for phosphate removal from wastewater is urgently needed due to the environmental issue caused by excessive phosphorus. In this study, calcium aluminum layered double hydroxides (CaAl-LDHs) and six amino acid intercalated calcium aluminum layered double hydroxides (CaAl-amino acid-LDHs) were prepared and compared for their phosphate adsorption performance. L-Aspartic acid intercalated calcium aluminum layered double hydroxides (CaAl-Asp-LDHs) exhibited the highest phosphate adsorption capacity and faster removal rate compared to CaAl-LDHs. The phosphate adsorption mechanism on CaAl-Asp-LDHs involved electrostatic attraction, hydrogen bonds, complexation, and ion exchange. This environmentally friendly material shows promising potential for efficient phosphate removal from aquatic environments.

Summary: Studying the diffusion properties of hydrogen is important for designing new proton conductors. In the past, the chemical diffusion coefficient of hydrogen in proton conductors was usually obtained through a manual calculation method, resulting in difficulty in controlling the calculation accuracy. To address this issue, a mathematical algorithm and C language computer program were developed to calculate the chemical diffusion coefficient based on Fick's second law and Romberg numerical integral. The algorithm showed high precision and powerful computing function, and has the potential to replace the manual calculation method in calculating the chemical diffusion coefficient for hydrogen in proton conductors.
