Nature of the Oxide Film Present on Iron after Inhibition in 0·05 M Chromate SolutionsChemical and microprobe analyses have been used to study the composition of the oxide films formed on iron by 0·05 M potassium chromate, pH 48.doi:10.1179/000705974798321413...
IT is sometimes assumed that the oxide film formed on iron at room temperatures is uniform in thickness across a specimen, and that where several oxides exist together they are present as layers stacked neatly one above the other. In an electron microscope investigation of the oxidation of mild ...
The authors report magnetotransport evidence for the coexistence of a two-dimensional (2D) superconducting state and a 2D ferromagnetic state at the interface between amorphous CaZrO3film and KTaO3single crystal. Moreover, the magnetoresistance hysteresis reaches a maximum near the superconducting transit...
an oxide film is formed on the surface of the metal. The rate of formation, composition and stability of this film have been investigated by chemical analysis and electrometric methods. The film consists mainly of oxides of iron and at 30° it grows to a fairly constant thickness of 3×10...

Researchers demonstrate a compact photonic mmWave radar based on a 4-inch wafer-scale thin-film lithium niobate technology. Multi-target ranging with 1.50 cm resolution and velocity measurement with a resolution of 0.067 m s−1are achieved. An inverse synthetic aperture radar with a two...
Efficient propagation of a chiral magnonic edge state in a strongly correlated oxide Long-distance propagation of a chiral magnonic edge state, through nanochannels and at room temperature, has been observed in engineered manganite thin films that have spiral spin texture and low magnetic damping. The...
Through the use of a plasmon-active atomically sharp tip and an ultrathin insulating film, and precise junction control in a highly confined nanocavity plasmon field at the scanning tunnelling microscope junction, sub-nanometre-resolved single-molecule near-field photoluminescence imaging with a spatial...
Discovery of fast and stable proton storage in bulk hexagonal molybdenum oxide Nanostructured electrode materials pose several challenges, including poor volumetric performance, severe side reactions, high costs, and complexity. Here, the authors develop a micrometer-sized bulk hexagonal molybdenum oxide wi...
