Abstract: A container for containing food or liquid is provided. The container includes a body portion, a lid and an attachment. The lid is detachably disposed on the body portion. The attachment is configured to be disposed on the lid or the body portion and includes a magnetic attraction member and a connecting structure. The magnetic attraction member is adapted to be magnetically connected to a mobile electronic device. The connecting structure is disposed between the magnetic attraction member and the container for selectively fixing the magnetic attraction member at a first position or a second position. The connecting structure includes a fastening member, and the fastening member is adapted to be detachably fastened to the body portion or the lid.

Abstract: A container for containing food or liquid is provided. The container includes a body portion, a lid and an attachment. The lid is detachably disposed on the body portion. The attachment includes a magnetic attraction member and a connecting structure. The magnetic attraction member is independent from the lid and adapted to be magnetically connected to a mobile electronic device. The connecting structure is disposed between the magnetic attraction member and the container for selectively fixing the magnetic attraction member at a first position or a second position. At least a portion of the connecting structure is fixed to the container.

Abstract: A process for providing elemental metals or metal oxides distributed on a carbon substrate or self-supported utilizing graphite oxide as a percursor. The graphite oxide is exposed to one or more metal chlorides to form an intermediary product comprising carbon, metal, chloride, and oxygen. This intermediary product can be further processed by direct exposure to carbonate solutions to form a second intermediary product comprising carbon, metal carbonate, and oxygen. Either intermediary product may be further processed: a) in air to produce metal oxide; b) in an inert environment to produce metal oxide on carbon substrate; c) in a reducing environment to produce elemental metal distributed on carbon substrate. The product generally takes the shape of the carbon precursor.
