  • Patterned chemical sensor having inert occluding layer
    Patent number: 8955515
    Abstract: A sensor 40 that detects a chemical such as an organic vapor. The sensor 40 includes a film that has a film body 58 that includes a detection layer 48 and that is responsive to the presence of a chemical by providing a color change. The film also includes an occluding layer 54 that has a first major surface 59 and that is bound to the film body 58 but is inert to the detection layer 48 to preclude the occluding layer 54 and the chemical from causing a color change in the film body 58 in an area 42 normal to the first major surface 59 of the occluding layer 54. A sensor having this construction can provide a distinctly visible image on the sensor, which may be helpful in evaluating the remaining life of a filter cartridge.

  • Catalytically active gold supported on thermally treated nanoporous supports
    Patent number: 8137750
    Abstract: The present invention provides technology for controlling, or tuning, the catalytic activity of gold provided upon nanoporous supports such as those derived from nanoparticulate titania. It has been discovered that the nature of the surfaces of the nanoparticles used to support a nano-metal catalyst, such as catalytically active gold, has a profound effect upon the catalytic properties of the supported catalyst. The support surface may be altered as desired to control the activity of the gold. The present invention teaches how thermal treatment of nanoparticulate media incorporated into a nanoporous support prior to deposition of catalytically active gold dramatically suppresses the ability of a resultant catalyst system to oxidize hydrogen. Yet, the system still readily oxidizes CO.
