Summary: By partially substituting La, the critical temperature (T-MIT) of rare-earth nickelates (ReNiO3) can be reduced to 83 K while maintaining an abrupt switch in resistivity. The strengthening of the metallic orbital configuration and reduction in the ground state band gap via La-substitution of Re in NdNiO3 and PrNiO3 are confirmed through near edge X-ray fine structure analysis and density function theory calculations.

Summary: The recent discovery of superconductivity in doped infinite layer nickelates RNiO2 is intriguing, as they are isostructural to doped (Ca, Sr)CuO2 which exhibit superconductivity at about 110 K. Investigating the similarities and differences between these oxides will provide new insights into the mechanism of high Tc superconductivity in correlated electron systems. This paper reviews experimental and theoretical works on the new superconductor and discusses future prospects for the 'nickel age' of superconductivity.

Summary: High-temperature technologies like solid oxide cells (SOC) are being used for power-to-fuel and vice versa conversion, but durability and compatibility issues at high temperatures are still being addressed. Thus, there is a growing focus on optimizing the physical, mechanical, and chemical properties of SOC materials at lower temperatures. Finding suitable air electrodes remains a significant challenge. Lanthanide nickelates with Ruddlesden-Popper (RP) and perovskite structures are emerging alternatives due to their fast ion and electron transport, as well as flexible oxygen stoichiometry. This review aims to document the research and development status of RP nickelate air electrodes and compare their electrochemical performance.

Summary: Perovskite rare earth nickelates exhibit rich physics in metal-insulator and anti-ferromagnetic transitions, and the debate on the collinear or noncollinear magnetic structures has finally been shed new light on, thanks to the discovery of two kinks in temperature-dependent magnetic susceptibilities, indicating the noncollinear nature of the magnetic structure in bulk nickelates. The prediction based on symmetry consideration is strongly supported by existing measurement results.

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: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
