The compatibility of increased sensitivity with both reliability and durability was difficult, since in a gas sensor composed of polycrystalline grains or ceramic particles, there is a trade-off relationship between increasing sensitivity through particle size reduction and change with time due to grain growth. Moreover, it was difficult to integrate a ceramic sensor with high sensitivity, high durability and high reliability with a Si integrated circuit in the monolith. A gas sensor is composed of an artificial nano-structure ceramic film where a change in the ceramic structure due to grain growth, etc. does not occur because of heat. The ceramic thin film is formed to a pattern shaped template on a nanometer level by using a sol-gel method and cured adequately to form precisely. Moreover, the above-mentioned gas sensor is integrated with an integrated circuit in the monolith.

A method is disclosed for generating and delivering an aerosol of a unique composition for treating stored crops. One aspect of the invention is such a composition wherein at least 80% to 98% of the components thereof have a particle size value no greater than 10 microns, whereby nearly any type of aerosol generator may effectively generate the aerosol because the particle size distribution of the components eliminates the need for further particle size reduction.
