摘要： A graphene sheet film as a film-like assembly of two or more graphene sheets 11 to 25 is provided. The graphene sheet film uses a graphene sheet assembly 101 that includes: first carbon nanotubes 31 to 48 that join the graphene sheets 11 to 25 to each other and form graphene sheet laminates 61 to 65 in which the graphene sheets 11 to 25 are laminated with the sheet planes being paralleled to each other; and second carbon nanotubes 51 to 56 that connect the graphene sheet laminates 61 to 65 to each other. This makes it possible to provide a graphene sheet film having high capacitor performance with respect to energy density and output density, a method for producing the same, and a graphene sheet capacitor using such graphene sheet films.

摘要： Exfoliating transition metal oxide lithium intercalation particles having lithium ions intercalated between transition metal oxide nanosheets includes electrochemically oxidizing a transition metal in first transition metal oxide lithium intercalation particles from a first oxidation state to a second oxidation state, inserting first cations having a radius exceeding the radius of a lithium ion into the vacancies, reducing the transition metal from the second oxidation state to the first oxidation state, and exfoliating the transition metal oxide nanosheets from the second transition metal oxide lithium intercalation particles to yield dispersed transition metal oxide nanosheets comprising the transition metal in the first oxidation state and oxygen. The dispersed transition metal oxide nanosheets can be reassembled to yield a material suitable for a lithium-ion battery cathode. Metal oxide sodium intercalation particles can be similarly exfoliated and reassembled to yield a material suitable for a sodium-ion battery cathode.

摘要： Systems and methods are provided for performing the required phase calculation in a telecommunications system in order to optimize system performance more quickly and with reduced complexity as compared to prior approaches to solving this problem. In accordance with the preferred exemplary embodiment of the present invention, the phase delay of the precursor equalizer (EQ) is calculated off-line and as a result it is not necessary to fill the precursor EQ delay line with the indicated number of symbols as in the previous approach. Additionally, because the precursor EQ is fractionally spaced, both sine and cosine values of the 4kHz tone's initial phase can be achieved simultaneously. As a result, only 36 quick timing sequence (QTS) symbols are needed in order to perform the required estimation.
