Spintronic systems exploit the fact that the electron current is composed of spin-up and spin-down carriers, which are more easily disturbed than electronic systems. Here, we investigate the spin transport properties of a single phenalenyl or pyrene molecule connected to zigzag graphene nanoribbon electrodes by using the non-equilibrium Green's function formalism with density functional theory. We...
Controlling magnetic transport through a single molecule remains one of the most fundamental challenges of spin electronics. Here, we investigate the effects of the redox reaction on the magnetic transport properties of a single anthraquinone (AQ) molecule connected to zigzag graphene nanoribbon electrodes by using the non-equilibrium Green's function formalism with density functional theory. Two...
Amino-functionalization of carbon nanotubes (CNTs) attached to carbon paper (CP) has been achieved using one synthesis protocol: (i) chemical oxidation, (ii) acyl chlorination, and (iii) amidation. The amidation reaction of the carboxylic groups in oxidized the CNT/CP hybrids enables the formation of terminal amino groups on the CNT sidewalls. The functionalized CNTs were characterized by Raman spectroscopy,...
The study examines the water/oil repellency and the sliding behavior of carbon papers (CPs) decorated with carbon nanotube (CNT) forest, prepared by using a catalytic chemical vapor deposition. The topography showed that CNTs with 20–40nm grown on CPs form a hierarchical nano/submicron scale roughness. The CNT–CP composite surface with a thin fluoro-silica coating exhibits excellent water/oil repellency...
A method for the synthesis of millimeter-scaled graphene films on silicon carbide substrates at low temperatures (750°C) is presented herein. Ni thin films were coated on a silicon carbide substrate and used to extract the substrate’s carbon atoms under rapid heating. During the cooling stage, the carbon atoms precipitated on the free surface of the Ni and formed single-layer or few-layer graphene...
Superhydrophobic carbon fabric with micro/nanoscaled two-tier roughness was fabricated by decorating carbon nanotubes (CNTs) onto microsized carbon fibers, using a catalytic chemical vapor deposition and subsequent fluorination surface treatment. The superhydrophobic surfaces are based on the regularly ordered carbon fibers (8–10μm in diameter) that are decorated by CNTs with an average size of 20–40nm...
