Thermodynamic stability of perovskite and lanthanum nickelate-type cathode materials for solid oxide fuel cells
… of SOFCs. Lanthanum nickelate, La2NiO4+δ (LNO), is a mixed ionic and electronic conductor that has competitive surface oxygen exchange and transport properties and excellent electrical conductivity compared to perovskite-type oxides. This makes it an excellent candidate for solid oxide fuel …

Preparation and Characterization of Ferroelectric Thin Films for Tunable and Pyroelectric Applications
… have been successfully deposited on LaNiO3 (LNO)/SiO2/Si substrates by PLD. The role of oxygen pressure and the effect of thickness on the microstructure, electrical and pyroelectric properties of BTS thin films have been systematically studied. BTS thin films deposited at higher oxygen …

Fundamental studies of perovskite related oxide thin films for oxygen electrocatalysis at intermediate temperatures
… kinetics of a-axis-oriented La2NiO4+[delta] (LNO) thin films increases with decreasing film thickness. Increasing volumetric strains in the LNO films at elevated temperatures are correlated with increasing surface exchange kinetics and decreasing film thickness. Volumetric strains may alter …

Insights on the synthesis, properties, and performance of high-nickel layered oxide cathodes
… oxygen pressure during the synthesis of LiNiO₂ (LNO) is investigated. Increasing O₂ pressure increases the oxygen chemical potential, reducing the formation of oxygen vacancies within the layered oxide lattice. Consequently, the LNO structure possesses lower cation disordering and achieves a near …

THE EFFECT OF ALTERNATING DISTRIBUTION OF TRANSITION METALS IN LAYERED MATERIALS ON OXYGEN EVOLUTION CATALYSIS
… cobalt oxide (LCO) and lithium nickel oxide (LNO) layered catalysts. LCO and LNO contains various oxidation states (or spin states) of cobalt and nickel atoms. With alternatively stacking a high-AOS and a low-AOS cobalt (or nickel) oxide sheets one by one, the electrochemical OER catalytic …

Microultrasound Imaging of Tissue Dysplasia
… of ultra-thinning processes for lithium niobate (LNO) and fabrication of novel ‘mass-spring’ matching layers using carefully controlled vacuum deposition is demonstrated. The effectiveness of this technique was quantified by applying multiple matching layers to 3 mm diameter 45 MHz LNO µUS …

Design and synthesis of Ni-rich and low/no-Co layered oxide cathodes for Li-ion batteries
… multielement-doped LiNi0.96Mg0.02Ti0.02O2 (Mg/Ti-LNO) as a model platform. We observed that dopants Mg and Ti diffuse from the surface to the bulk of cathode particles below 300 °C long before the formation of any layered phase, using a range of synchrotron spectroscopic and imaging diagnostic …

Scattering Scanning Near-Field Optical Microscopy on Anisotropic Dielectrics
Near-field optical microscopy allows the nondestructive examination of surfaces with a spatial resolution far below the diffraction limit of Abbe. In fact, the resolution of this kind of microscope is not at all dependent on the wavelength, but is typically in the range of 10 to 100 nanometers. On …
