The present invention relates to a method for preparing a two-dimensional hybrid composite that is capable of solving the problems with the two-dimensional plate type materials, that is, step difference, defects, stretching, etc., that occur as the second-dimensional plate type materials overlap with one another. The present invention provides a method for preparing a two-dimensional hybrid composite that includes: (a) preparing a first plate type material in the solid or liquid state; (b) mixing a second plate type material with the first plate type material, the second plate type material being thinner and more flexible than the first plate type material; (c) mixing a solid or liquid binder with the first and second plate type materials to make the first and second plate type materials partly contact with or apart from each other; and (d) solidifying a composite formed by the steps (a), (b) and (c).

A non-volatile memory circuit in embodiments of the present invention may have one or more of the following features: (a) a logic source, and (b) a semi-conductive device being electrically coupled to the logic source, having a first terminal, a second terminal and a nano-grease with significantly reduced amount of carbon nanotube loading located between the first and second terminal, wherein the nano-grease exhibits non-volatile memory characteristics.

Provided are a sliding member for sealing and a seal device that exhibit good sealing performance even when used in an environment where silicon oxide is likely to be deposited.

A sliding member for sealing includes a sintered body consisting of 1.0 to 12.5 wt % of cerium oxide, a combination of 20 to 50 wt % of graphite and graphitizable carbon, and a remainder of non-graphitizable carbon. The sliding member for sealing is used as, for example, a rotary seal ring or a stationary seal ring.

Embodiments described herein relate generally to large scale synthesis of thinned graphite and in particular, few layers of graphene sheets and graphene-graphite composites. In some embodiments, a method for producing thinned crystalline graphite from precursor crystalline graphite using wet ball milling processes is disclosed herein. The method includes transferring crystalline graphite into a ball milling vessel that includes a grinding media. A first and a second solvent are transferred into the ball milling vessel and the ball milling vessel is rotated to cause the shearing of layers of the crystalline graphite to produce thinned crystalline graphite.
