Abstract: A graphene-based electrically tunable nanoconstriction device and a non-transitory tangible computer readable medium encoded with a program for fabricating the device that includes a back-gate dielectric layer over a conductive substrate are described. The back-gate dielectric layer may be hexagonal boron nitride, mica, SiOx, SiNx, BNx, HfOx or AlOx. A graphene layer is an AB-stacked bi-layer graphene layer, an ABC-stacked tri-layer graphene layer or a stacked few-layer graphene layer. Contacts formed over a portion of the graphene layer include at least one source contact, at least one drain contact and at least one set of side-gate contacts. A graphene channel with graphene side gates is formed in the graphene layer between at least one source contact, at least one the drain contact and at least one set of side-gate contacts. A top-gate dielectric layer is formed over the graphene layer. A top-gate electrode is formed on the top-gate dielectric layer.

Abstract: A sectional container has a body, a first surface, a second surface, a third surface, a chamber, an opening, multiple first protrusions and multiple first connecters. The first surface, the second surface and the third surface are formed on the body. The second surface is opposite the first surface. The third surface is between and connects the first surface with the second surface. The chamber is formed between the first surface and the second surface. The opening is formed in the third surface and communicates with the chamber of the body. The first protrusions are mounted on and protrude from the first surface. The first connecters are mounted on the second surface and each first connecter corresponds to and aligns with one of the first protrusions. Therefore, multiple sectional containers can be combined securely in a vertical, horizontal or intersecting manner selectively.

Abstract: A receptacle includes a pouch-like body having an opening, a cover pivotally connected to a side face defining the opening so as to close selectively the opening and a seat detachably connected to a bottom face of the pouch-like body to allow the pouch-like body to be slanted relative to a ground surface.

Abstract: A mouse with one or more additional multifunctional control members is disclosed. The mouse comprises a main body and at least one control stick, which defines the function of at least one control key/button. In use, a user may use the control stick to enter several commands so as to reach the goal of easy use and control under the windows operating system.

Abstract: A method of using a mouse to carry out multimedia adjustments is disclosed. A conversion program is used to define and switch between at least two key function sets so as to allow a user to use the mouse to carry out adjustments on the selected multimedia files without moving the cursor.
