  • Hollow sphere with mesoporous structure and method for manufacturing the same
    Patent number: 9073949
    Abstract: The present invention relates to a hollow sphere with a mesoporous structure, and a method for manufacturing the same. The hollow sphere with a mesoporous structure comprises: a shell with plural mesopores penetrating the shell, wherein the shell comprises: a mesoporous silicon oxide material, and mesopores of the mesoporous silicon oxide material are arranged in Ia3d cubic symmetry. In addition, according to the method of the present invention, the aforementioned hollow sphere with the mesoporous structure can be easily obtained by use of mixed surfactants of a cationic surfactant and a non-ionic surfactant.

  • Gas sensor and method thereof
    Publication number: 20100288014
    Abstract: A gas sensor comprises a first surface-acoustic-wave device, at least one further surface-acoustic-wave device, and a control device. The first surface-acoustic-wave device includes a piezoelectric substrate, a pair of transducers and an external circuit. The pair of transducers consists of a first transducer and a second transducer, and they are formed on two sides of the piezoelectric substrate. The first transducer is utilized to generate a surface acoustic wave on the piezoelectric substrate. The external circuit electrically connects to the pair of transducers. At least one further surface-acoustic-wave device includes at least one first surface-acoustic-device and a sensing porous thin film of which two sides are formed on the pair of the transducers. The control device is utilized to control only one external circuit to become activated at one time.
