Superconducting nickelates appear to be difficult to synthesize. Since the chemical
reduction of ABO 3 [rare earth (A), transition metal (B)] with CaH 2 may result in both ABO 2 …

Superconducting states onsetting at moderately high temperatures have been observed in
epitaxially stabilized RE NiO2-based thin films. However, recently, it has also been reported …

We report a comprehensive study of magnetic correlations in LaNiO 2, a parent compound
of the recently discovered family of infinite-layer (IL) nickelate superconductors, using …

Studies on magnetic oxyhydrides have been almost limited to perovskite-based lattices with
corner-sharing octahedra with a M–H–M (M: transition metal) angle of θ∼ 180°. Using a …

The electrocatalytic synthesis of high-value-added urea by activating N2 and CO2 is a green
synthesis technology that has achieved carbon neutrality. However, the chemical adsorption …

By a combination of x-ray diffraction, structural chemistry, and DFT calculations, the
presence and location of anionic hydrogen in the two new, layered lanthanide oxyhydrides …

La x Sr2–x NiRuO6, La x Sr4–x NiRuO8, and La x Sr3–x NiRuO7 are, respectively, the n=∞,
1, and 2 members of the (La x/2Sr1–(x/2)) n Sr (Ni0. 5Ru0. 5) n O3 n+ 1 compositional …

The four compounds A3MO4H (A= Rb, Cs; M= Mo, W) are introduced as the first members of
the new material class of the transition oxometalate hydrides. The compounds are …

The work presented in this thesis focuses on the topochemical reduction of Ir-containing
oxides with perovskite-type structures to form novel anion-deficient and mixed-anion …

The rank and signature of the linear transformation between the reactant and product unit
cells are utilized to classify solid-state reactions. The classification is applicable to topotaxy …
