Abstract: A superconducting article includes a substrate and a superconducting metal oxide film formed on the substrate. The metal oxide film including ions of an alkali metal, ions of a transition metal, and ions of an alkaline earth metal or a rare earth metal. For instance, the metal oxide film can include Rb ions, La ions, and Cu ions. The superconducting metal oxide film can have a critical temperature for onset of superconductivity of greater than 250 K, e.g., greater than room temperature.

Abstract: A method and system for detecting a concealed foreign object carried by a body (P) by collecting radiation (R) from the body (P) indicative of a radiation response of the body (P) to environmental temperature changes which the body (P) is subjected to while entering or emerging from a transient inducing space (TIS) of environmental temperature changes and generating thermal data indicative of the response. The TIS has a volume substantially large relative to that of the body (P) and is configured to enable concentration of a temperature field within the TIS. The TIS may be defined by a gate (21) having at least one of the following configurations: side walls (21A, 21B) at opposite sides of the body path or side walls (21A, 21B) at opposite sides of the body path and an upper wall (21C) above the body path. The gate may be a substantially -shaped gate, -shaped gate, or a carousel gate.

Abstract: An object (12) concealed in a body (16) is detected by transiently heating or cooling at least part of the body surface, imaging that part of the surface in the mid- or far infrared, and seeking the concealed object (12) in the image(s). Alternatively, the body (16) is imaged as the temperature of its environment fluctuates naturally. Preferably, multiple infrared images are acquired and are processed to provide a measure of the body's thermal diffusivity, the object (12) then being sought according to that measure of thermal diffusivity. Most preferably, the heated/cooled part of the surface is imaged in the visible or near-infrared band too, and the two sets of images are processed together to provide the measure of the body's thermal diffusivity.
