Abstract: The present invention relates to a hydrophilic metal thin film, which is formed by stacking a plurality of columnar structures. A plurality of tetrahedral structures is on the surface of the hydrophilic metal film, which is formed on the top of the columnar structures. The width of the tetrahedral structures is 15 nm to 120 nm. The hydrophilic metal thin film comprises: 35 to 95 at % of iron, 5 to 20 at % of chromium. The above-mentioned hydrophilic metal thin film is formed by magnetron sputtering method under the working pressure of argon gas ranging from 6 mTorr to 13 mTorr, and the sputtering time exceeds 20 minutes.

Abstract: A tattoo needle structure is provided. A tattoo needle has a plurality of needle tips, an ink holding space is formed by the arrangement of the needle tips, and a multi-component alloy film is deposited on each needle tip of the tattoo needle by sputtering technology, so that when the tattoo needle is dipped into the tattoo ink, the tattoo ink does not stick to the surface of the multi-component alloy film by the hydrophobic property of the multi-component alloy film, and the tattoo ink is contained in the ink holding space by the cohesive property of the tattoo ink. Thus, when the tattoo needle is dipped into the tattoo ink and the tattoo process is performed, the dyeing area of the skin with the tattoo ink is the cross-sectional area of the ink holding space, thereby achieving the technical effect of improving the contouring resolution of a tattoo.

Abstract: A method of fabricating a nanoporous metal structure, such as a nanoporous metal (NMP) supported Pd catalyst suitable for use in a direct methanol fuel cell (DMFC), is includes the steps of (a) providing a piece of Au55Cu25Si20 alloy glass ribbon with a thickness of 50 ?m, (b) dealloying the piece of alloy glass ribbon by reacting with iron (III) chloride solution to form a free-standing NPM ribbon, (c) depositing a thin film of PdCo of a thickness of 100 nm on the NPM ribbon by RF magnetron sputtering with Pd0.5Co0.5 (atomic percent) as target in an argon atmosphere, and (d) electrochemically dissolving some of the Co on the thin film of PdCo to induce migration of Au from the NPM ribbon to the thin layer of PdCo.
