摘要:
Disclosed is a microstructure comprising an aluminum anodized film bearing through micropores, wherein a surface of the microstructure is covered with a protective film for preventing hydration of the aluminum anodized film. The microstructure may be used as a porous alumina membrane filter excellent in filtration rate and its stability with time.
摘要:
Described is a structural body including at least partially an aluminum member having on a surface an anodized film with micropores present, in which: the micropores have a coefficient of variation in pore size of 5 to 50%; and the micropores are each sealed with a metal. The structural body can generate localized plasmon resonance having a sufficiently large intensity and be produced at low cost through a simple production process, and having a large surface area.
摘要:
In a method of manufacturing a microstructure, an aluminum member having an aluminum substrate and a micropore-bearing anodized layer present on a surface of the aluminum substrate is subjected at least to, in order, a pore-ordering treatment which involves performing one or more cycles of a step that includes a first film dissolution treatment for dissolving 0.001 to 20 wt % of a material constituting the anodized layer and an anodizing treatment which follows the first film dissolution treatment; and a second film dissolution treatment for dissolving the anodized layer, thereby obtaining the microstructure having micropores formed on a surface thereof. This method enables a microstructure having an ordered array of pits to be obtained in a short period of time.
摘要:
A microstructure includes an anodized aluminum layer that has on a surface thereof micropores, at least some of which contain a catalyst, in a micropore array with a degree of ordering of at least 40%. A method of manufacturing the microstructure includes anodizing an aluminum member to form on its surface an anodized layer having micropores, removing the aluminum member, and supporting a catalyst on at least part of the anodized layer. The microstructure is excellent in heat resistance.
摘要:
A microstructure with regularly arranged micropores is obtained by anodizing an aluminum layer having a Vickers hardness Hv of up to 20. The microstructure has a well-ordered region of large surface area and can be manufactured at low cost.

摘要:
In a message receiving apparatus, a radio paging signal is demodulated into a baseband signal. The baseband signal is decoded into corresponding data. Address information is recovered from the data. Message information is recovered from the data. The recovered message information is subjected to an error correction process. On the other hand, the recovered address information is prevented from being subjected to the error correction process.
