A method of forming a nanostructure having the form of a tree, comprises a first stage and a second stage. The first stage includes providing one or more catalytic particles on a substrate surface, and growing a first nanowhisker via each catalytic particle. The second stage includes providing, on the periphery of each first nanowhisker, one or more second catalytic particles, and growing, from each second catalytic particle, a second nanowhisker extending transversely from the periphery of the respective first nanowhisker.

Gas Diffusion Electrodes (GDES) play a pivotal role in clean energy production as well as in electrochemical processes and sensors. These gas-consuming electrodes are typically designed for liquid electrolyte systems such as phosphoric acid and alkaline fuel cells, and are commercially manufactured by hand or in a batch process.

This invention pertains to GDEs and gas diffusion media with new structures for systems using membrane electrode assemblies (MEAs), and automated methods of manufacture that lend themselves to continuous mass production Unexpected improvements in gas and vapor transport through the electrode are realized by incorporating a new dispersion process in the construction, reformulating the applied mix with solution additives, and creating a novel coating structure on a conductive web. Furthermore, combining these changes with a judicious choice in coating methodology allows one to produce these materials in a continuous, automated fashion.

In a planar waveguide optical circuit 1, a inclined groove 3 is formed at an inclination angle .theta. with respect to the vertical axis so as to cross optical waveguides 2.sub.n. A reflection filter 4 structured such that the difference in reflectivity between orthogonal polarization is compensated for with respect to signal light is installed inside the groove 3, the reflected light from the reflection filter 4 is detected by the photodetectors 6.sub.n, and the optical intensity of the signal light is monitored. This makes it possible to accurately monitor the optical intensity regardless of the polarization state of the signal light. Also, since the inside of the groove 3 including the reflection filter 4 is sealed with a filler resin 5, any deterioration in long-term stability that would otherwise be caused by contamination of these components is prevented. Thus, the optical waveguide module with which the structure of the optical circuit is simpler, and the optical intensity can be correctly monitored regardless of the state of polarization of the signal light is realized.
