In accordance with at least one aspect of this disclosure, an ultraviolet radiation (UV) sensor includes a UV sensitive material and a first electrode and a second electrode connected in series through the UV sensitive material such that UV radiation can reach the UV sensitive material. The UV sensitive material can include at least one of zinc tin oxide, magnesium oxide, magnesium zinc oxide, or zinc oxide. The electrodes can be interdigitated comb electrodes.

Radiation sensors

A detector for detecting a hazardous safety condition. The detector includes a housing, an electrochromic material disposed within the housing, and a power source in operative electrical communication with the electrochromic material, the electrochromic material providing a visual display to indicate a condition of the detector.

Electrochromic device for safety detector

A method of fabricating an article includes providing an arrangement of loose nanowires and bonding the loose nanowires in the presence of carbon together into a unitary cellular structure.

Carbon as an aide for ductile nanocellular foam

A method of fabricating an article includes providing an arrangement of loose nanowires, forming the loose nanowires into a gas turbine engine airfoil by depositing the loose nanowires into a mold that has a geometry of the gas turbine engine airfoil, and bonding the loose nanowires together into a unitary cellular structure that has the geometry of the gas turbine engine airfoil.

Fabrication of articles from nanowires

A method of making an ultraviolet sensor includes applying a metal-containing solution to a substrate using a spin coating technique to form a metal-containing coat. The metal-containing coat is baked and pyrolyzed to form a metal-containing oxide film on the substrate. The metal-containing oxide film has a cubic crystalline structure suitable for ultraviolet photodetectors in flame detection applications.

Ultraviolet photodetectors and methods of making ultraviolet photodetectors

An ultraviolet photodetector for a sensor device includes a film deposited on a substrate. The film includes a compositionally graded magnesium-zinc oxide having a ratio of magnesium-to-zinc that decreases between a portion of the film adjacent to the substrate and a portion of the film opposite the substrate for shifting the peak absorption of the film toward the visible wavelengths of the electromagnetic spectrum.
