  • Patent number: 8343437
    Abstract: Compositions, devices and processes related to etching of a very thin layer or fine particles of a metal are disclosed for monitoring a variety of parameters, such as time, temperature, time-temperature, thawing, freezing, microwave, humidity, ionizing radiation, sterilization and chemicals. These devices have capabilities of producing a long and sharp induction period of an irreversible visual change. The devices are composed of an indicator comprising a very thin layer of a metal and an activator, e.g., a reactant, such as water, water vapor, an acid, a base, oxidizing agent or their precursors, which is capable of reacting with the said indicator. Ink formulations composed of a metal powder and a proper activator can be used for monitoring several sterilization processes, such as sterilization with steam. When water is used as an activator, a thin layer of metals, such as that of aluminum can be used as steam sterilization or humidity indicator.

  • Patent number: 6830812
    Abstract: A carbon material is formed by heat-treating a carbonaceous material in a reaction mix of boron oxide or its precursors and ammonia-generating phases such as melamine or its like in a nitrogen atmosphere to temperatures of 1600 to 2000° C. The surface of the carbonaceous material is transformed into a carbon material that is resistant to oxidation to temperatures of 900° C., enabling machined components to be utilized for weeks at that temperature. The carbon material also is stable in inert or vacuum environments to temperatures in the range of 1500 to 2000° C., enabling its use as aluminum evaporative boats and the like.
