    摘要： Carbon nanotubes are formed on projections on a substrate. A metal, such as nickel is deposited on the substrate with optional platforms, and heated to form the projections. Carbon nanotubes are formed from the projections by heating in an ethylene, methane or CO atmosphere. A heat sensor is also formed proximate the carbon nanotubes. When exposed to IR radiation, the heat sensor detects changes in temperature representative of the IR radiation. In a gas sensor, a thermally isolated area, such as a pixel is formed on a substrate with an integrated heater. A pair of conductors each have a portion adjacent a portion of the other conductor with projections formed on the adjacent portions of the conductors. Multiple carbon nanotubes are formed between the conductors from one projection to another. IV characteristics of the nanotubes are measured between the conductors in the presence of a gas to be detected.

    摘要： An apparatus which comprises: an organic-substance oxidation part in which organic substances contained in a sample water supplied are oxidized into carbon dioxide; a carbon dioxide separation part in which the carbon dioxide contained in the sample water is caused to permeate and come into a measurement water; and a conductivity measurement part in which the conductivity of the measurement water is measured. The carbon dioxide separation part comprises: a sample water channel in which sample water flows; an intermediate water part in which intermediate water having a higher pH value in a neutral region than the sample water is present; and a measurement water channel through which the measurement water comprising deionized water flows. The sample water channel is in contact with the intermediate water part through a gas-permeable membrane, and the intermediate water part is in contact with the measurement water channel through a gas-permeable membrane.
