Abstract: An expandable device for attachment to a portable electronic device having first and second surfaces includes a button having a top side, a bottom side, and a coupling portion and further includes an elongated body having a top side, a bottom side, and a platform coupling portion. The button is movable between an expanded position and a collapsed position. The bottom side of the platform engages a portion of the portable electronic device and the platform coupling portion engages the coupling portion of the button. When coupled to the positioning platform, the button is movable between a first position where the button is positioned along the first surface of the portable electronic device and a second position where the button is positioned along the second surface of the portable electronic device.

Abstract: The present invention relates to a terrarium of the closed type which includes a base for holding a plant (typically tropical plant varieties such as moss) and any excess moisture, and a removable lid which together with the base forms an enclosure around the plant and creates a humid and sheltered environment. The terrarium may include a removable lid which has an internal upper surface that is shaped to direct condensate forming on the upper surface of the lid to a particular area of the plant. The terrarium may include a base and lid having overlapping portions wherein the overlapping portions include edge deviations or apertures that may be brought into co-alignment to provide for no, partial or full aeration.

Abstract: Three-dimensional (3D) graphene nanoribbons and methods for fabricating 3D graphene nanoribbons that may readily function as solenoid windings and the like. In one embodiment, a method of fabricating a 3D graphene nanoribbon (100) may include coating a side surface (102A) of a 3D insert (102) with a metal (104) appropriate for graphene growth thereon. The method may also include growing a layer (106) of graphene directly on the metal coating. The method may also include removing a strip of the graphene layer and metal coating (106/104) to expose the side surface (102A) of the insert (102) while leaving a line (108) of graphene on metal winding around the insert (102) and extending continuously from a first end (108A) of the line (108) to a second end (108B) of the line (108).
