Enhanced thermopower of graphene films with oxygen plasma treatment.
In this work, we show that the maximum thermopower of few layers graphene (FLG) films could be greatly enhanced up to ∼700 μV/K after oxygen plasma treatment. The electrical conductivities of these plasma treated FLG films remain high, for example, ∼10(4) S/m, which results in power factors as high as ∼4.5 × 10(-3) W K(-2) m(-1). In comparison, the pristine FLG films show a maximum thermopower ...

متن کاملTreatment of Protein Using Oxygen Plasma Produced by RF Discharge
Removal of proteins from the surface of medical equipments are attempted using oxygen plasma produced by RF discharge. FTIR spectra indicate that the bonds of C-H and N-H in the casein protein are reduced after irradiation of oxygen plasma. Also, the second order structure of a protein such as α-helix and β-sheet are modified by the oxygen plasma. Complete removal of protein as remnants on the ...
متن کاملOxygen reduction by lithiated graphene and graphene-based materials.
Oxygen reduction reaction (ORR) plays a key role in lithium-air batteries (LABs) that attract great attention thanks to their high theoretical specific energy several times exceeding that of lithium-ion batteries. Because of their high surface area, high electric conductivity, and low specific weight, various carbons are often materials of choice for applications as the LAB cathode. Unfortunate...
متن کاملGraphene Nanoribbon Array Fabrication by Oxygen Gas Plasma Etching through Sub-micrometer Porous Filters
We investigate a novel method of fabricating a network of graphene nanoribbon structures. The process is a sharp departure from conventional nanolithographic techniques in both method and amount of time required. Epitaxial graphene prepared on single crystal 4H-SiC(0001) was etched with O2 plasma through 0.2 μm porous filters adhered to the surface of the sample. Thickness measurements using el...
