Summary: In this study, the introduction of a small amount of NiO to proton-conducting perovskite has been shown to greatly improve its chemical stability, even under high carbon dioxide partial pressure and wet conditions. The modified samples with NiO exhibit stable conductivity performance, regardless of grain sizes, while the unmodified samples show a noticeable drop in conductivity with decreasing grain size. These findings highlight the potential of transition metal additives in enhancing the chemical resistance of proton-conducting ceramics perovskites.

Summary: Proton-conducting perovskite oxide BaCe0.7Zr0.1Y0.2O3-delta (BZCY) is prepared using carbonate coprecipitation method with Tween-80 as the surfactant, resulting in well dispersed particles with an average size of 200 nm. The BZCY powder is used as the electrolyte material in a Ni-based anode-supported protonic ceramic fuel cell (PCFC). The electrolyte can be densified without any sintering aids at 1400 degrees C in open air, and the PCFC exhibits a peak power density of 1050 mW cm-2 at 700 degrees C, with a conducting activation energy of 0.36 eV. The superiority of the BZCY powder prepared using the coprecipitation method is demonstrated by comparing it with a BZCY powder made by conventional solid-state reaction method.

Summary: Proton-conducting ceramic membranes with asymmetric configuration have been increasingly studied due to their 100% H2 selectivity, high thermo-chemical stability, and lower cost compared to Pd-based membranes. In this study, porous BaCe0.65Zr0.20Y0.15O3-delta (BCZY) supports were fabricated for the first time using UV-assisted micro-extrusion. Different preparation methods of BCZY-based inks were evaluated to obtain eco-friendly formulations with high solid loading (>40 vol%). Printable inks with optimal shear thinning behavior were successfully extruded, allowing for deposition of up to three stacked layers without defects.

Summary: The study investigates the gas sensing properties of screen printed ceria and ruthenate-sensitized BaSnO3 sensors for detecting ammonia and formaldehyde gases at room temperature. The La-doped BaSnO3 sensor showed superior gas response towards ammonia and formaldehyde, but sensitization of ceria and ruthenate resulted in reduced gas responses. The presence of the fluorite structured phase ceria facilitated rapid oxidation of analyte gases, leading to fast response and recovery times in the sensor.

Summary: The recent discovery of water-in-salt electrolytes has led to a resurgence in research on aqueous batteries, with a focus on expanding the electrochemical window. The speciation of water in these electrolytes differs from that in conventional aqueous solutions, leading to altered interfacial properties. By using a small amount of water in nonaqueous electrolytes, researchers have been able to control interface properties and expand the electrochemical window of aqueous electrolytes.

Summary: In this study, the hydrogen generation performance of LPSO compounds and LPSO + Mg alloys in simulated seawater solution was investigated. Results showed that LPSO compounds, especially the single phase LPSO Mg(87.6N)i(5.5)Y(6.9), exhibited improved H2 generation features compared to pure Mg. Alloys containing both Mg and LPSO benefited from galvanic coupling between the two phases, leading to higher reactivity and lower activation energies.

Summary: The electrocatalytic epoxidation of alkenes using water as the sole oxygen source is a promising route toward sustainable synthesis of epoxides. In this study, the electrocatalytic epoxidation of cyclooctene at the surface of gold in hybrid organic/aqueous mixtures using acetonitrile solvent was investigated. The research demonstrated that a sacrificial mechanism is responsible for the epoxidation reaction, and the hydrophilicity of the electrode/electrolyte interface can be tuned to affect the reaction selectivity.

Summary: We present the synthesis pathway of nanostructured lithium iridates in molten salts, which allows for tunable particle and crystal sizes. The resulting materials exhibit phase-pure, layered alpha-Li2IrO3 structure with a significantly higher surface area than those obtained using traditional solid-state methodology. These nanoscaled alpha-Li2IrO3 materials show improved oxygen evolution reaction activity and demonstrate unique electrocatalytic behavior compared to their bulk counterparts. Furthermore, they exhibit good chemical and structural stability, showing minimal deactivation in KOH and H2SO4 electrolytes with low electrode catalyst loading. The enhanced iridium intrinsic activity observed in this study suggests the potential of high-temperature colloidal synthesis in designing electrocatalysts with enhanced mass activity.

Summary: Two-dimensional layered magnetic materials, such as the recently discovered VI3 ferromagnetic phase, have sparked great interest due to their unique spin dynamics properties, but incomplete understanding of their crystallographic structures remains a challenge. This study investigated VI3 crystal structures at low temperature using synchrotron x-ray and neutron powder diffraction, revealing structural models for the two-phase transitions and questioning the establishment of a long-range magnetic structure. Additionally, the magnetic properties of the LiVI3 phase, similar to CrI3 in electronic and crystallographic structures, were examined, showing antiferromagnetic behavior and providing insights for a better understanding of magnetism in low-dimensional compounds.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

This study introduces a stable and highly conductive ceramic-based solid electrolyte and a metal-organic framework catalyst to improve the safety and performance of Li-CO2 batteries. The optimized Li-CO2 cell shows outstanding specific capacity and cycle life, and the post-cycling analysis reveals the degradation mechanism of the electrodes. First-principles calculations based on density functional theory are also performed to understand the interactions between the catalyst and the host electrode.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
