Circuits and methods related to temperature sensing of regions within a superconducting integrated circuit (IC) using in-situ resonators are described. An example relates to a superconducting IC including a first resonator having a first spatial location in relation to a floor plan of the superconducting IC.

The superconducting IC further includes a feed line configured to provide a test signal to each of the first resonator and the second resonator in order to elicit a frequency response from the first resonator or the second resonator, where the frequency response is correlated with a first region within the superconducting IC corresponding to the first spatial location or with a second region within the superconducting IC corresponding to the second spatial location.

Aspects of the technology provide a method / system of sensing a change in temperature and / or strain in an optical fibre comprising a substantially continuous or quasi-continuous fibre Bragg grating. A difference spectrum is determined between a reference reflected spectrum of the fibre Bragg grating and a monitored reflected spectrum. The difference spectrum is analysed to determine whether the optical fibre is experiencing a change of type a)—a temperature increase or an extension—or of type b)—a temperature decrease or a contraction. The technology may be applied to sensing a change in temperature and / or strain in a superconductor or detecting a risk of a quench in a superconductor.

A metal foam structure is used for numerous energy applications such as battery, electrolyzer, fuel cell, carbon capture, thermal management, and others due to its enhanced surface area to be utilized for improved efficiency. A net-shape metal foam sheet or plate production with desired thicknesses without cutting process is thus required to significantly reduce the manufacturing cost and to be more price competitive against other types of existing similar materials such as carbon paper, metal foil, mesh, plate, and others. In order to achieve this, a vertical freeze casting is described where the freeze casting of the metal slurry takes place with the metal slurry plate mold being placed vertically with respect to the ground, whereas the conventional freeze casting process takes place with the metal slurry plate mold being placed horizontally with respect to the ground.
