Abstract: The disclosure relates to a thin vapor-chamber structure including a first cover and a second cover. The first cover has a first surface and a first clustered pattern. The first clustered pattern is disposed on the first surface, and has a plurality of first protruding stripes spaced apart from each other and extended along a first direction. The second cover has a second surface and a second clustered pattern. The first surface faces the second surface. The second clustered pattern is disposed on the second surface, and has a plurality of second protruding stripes spaced apart from each other and extended along a second direction. The first clustered pattern and the second clustered pattern are partially contacted with each other to form a wick. The lateral walls of the first protruding stripes and the second protruding stripes form a micro-channel meandering between the first surface and the second surface.

Abstract: The present disclosure provides a composite material layer including a core layer and a shell layer. The core layer includes foamed elastomers. The shell layer encapsulates the core layer and continuously covered surfaces of the foamed elastomers, wherein the shell layer includes a material having light absorption. The melting point of the core layer is higher than the melting point of the shell layer.

Abstract: A heat spreader comprising a casing, a micro-structure layer, a support device, and a working fluid is provided. The casing has an inner surface and is defined by a sealed chamber where the working fluid circulates therein. The micro-structure layer is formed on the inner surface of the casing, wherein the micro-structure layer comprises a first structure layer which is formed by the first metallic mesh. Specifically, the first metallic mesh forms the first structure layer on the inner surface through diffusion bonding so that the working fluid can circulate within the micro-structure layer by capillary action. In addition, the support device is disposed in the sealed chamber for supporting the casing. Thus, a heat spreader with a composite micro-structure can not only enhance the capillarity but also reduce the flowing resistance during operation.

Abstract: A nanomaterial with a core-shell structure is provided. The nanomaterial comprises a shell and a core, wherein the shell is located on at least a portion of the surface of the core. The shell is substantially composed of a first metal oxide. The core is substantially composed of a second metal oxide, while the second metal oxide is a non-stoichiometric compound. The inventive nanomaterial exhibits excellent properties, such as good gas sensitivity and better field emission property, and has a high applicability.

Abstract: A thickening method of an electroforming shim is provided to increase the thickness of a metal shim. In this embodiment, an active solder with a rare earth element is used to increase the moisture on the substrate surface for the solder during the combining process. Afterwards the oxides of the rare earth element are expelled by mechanical stirring to produce a clean contact surface. The melted fillers moisturize on the substrate surface to achieve the combination.
