Abstract: Examples disclosed herein relate to a heat sink. Examples include a thermoconductive base thermally coupled to a device. Examples include a fin thermally coupled to and extending from a first surface of the thermoconductive base to dissipate heat generated by the device. Examples include a heat insulation layer disposed on a distal end of the fin to insulate the distal end of the fin from heat generated by the device.

Abstract: This disclosure provides a sol-gel hybrid coating composition, comprising a sol-gel precursor, a polymer and a solvent, wherein the sol-gel precursor comprises tetraethyl orthosilicate and the polymer comprises polyurethane and polyacrylic. This disclosure also provides a coating process, comprising: subjecting a light metal to micro-arc oxidation treatment to form a first protection layer on the light metal, and coating the sol-gel hybrid coating composition onto the first protection layer to form a second protection layer. This disclosure further provides composite coating layers, comprising: a first layer obtained by micro-arc oxidation treatment, and a second layer obtained by dip coating with the sol-gel hybrid coating composition.

Abstract: Examples of a hinge for foldable components are described herein. In an example, the hinge can include a plurality of bracing elements, a bracing element from the plurality of bracing elements can be operably coupled to an adjacent bracing element from the plurality of bracing elements, to fold the plurality of bracing elements into an arcuate shape. Each bracing element can be supported and locked against the adjacent bracing element in the arcuate shape. The hinge can further include an end coupler at each longitudinal end of the hinge to couple the hinge to a flexible element.
