Loose graphene sheets, one to a few atomic layers thick, are often observed on freshly cleaved HOPG surfaces. A straightforward technique using electrostatic attraction is demonstrated to transfer these graphene sheets to a selected substrate. Sheets from one to 22 layers thick have been transferred by this method. One sheet after initial deposition is(More)
First results of the study of the process e + e − → 4π by the CMD-2 collaboration at VEPP-2M are presented for the energy range 1.05–1.38 GeV. Using an integrated luminosity of 5.8 pb −1 , energy dependence of the processes e + e − → π + π − 2π 0 and e + e − → 2π + 2π − has been measured. Analysis of the differential distributions demonstrates the dominance(More)
In a two-step method, carbon nanotubes, inorganic nanowires, or graphene sheets are connected between two anchor points to form nanomaterial air bridges. First, a recently developed method of forming directionally oriented polymer nanofibers by hand-application is used to form suspended composite polymer-nanomaterial fibers. Then, the polymer is sacrificed(More)
A B S T R A C T We describe a simple method for decorating graphene (1–5 layers) with Au and Ag nano-structures (nanoparticles, nanorods, and nanoplates). We deposit graphene electrostati-cally from highly-oriented pyrolytic graphite onto Si/SiO 2 surfaces functionalized with (aminopropyl)trimethoxysilane and grow the metal nanostructures by a seed-mediated(More)
The synthesis of single-wall carbon nanotubes of desired diameters and chiralities is critical to the design of nanoscale electronic devices with desired properties. The existing methods are based on self-assembly, therefore lacking control over the diameters and chiralities. The present work reports a direct route for rolling graphene. Specifically, we(More)
The response of two carbide derived carbons (CDCs) films to NH(3), N(2)O, and room air is investigated by four probe resistance at room temperature and pressures up to 760 Torr. The two CDC films were synthesized at 600 (CDC-600) and 1000 degrees C (CDC-1000) to vary the carbon morphology from completely amorphous to more ordered, and determine the role of(More)
Living cells contain a range of densely phosphorylated surfaces, including phospholipid membranes, ribonucleoproteins, and nucleic acid polymers. Hyperphosphorylated surfaces also accumulate in neurodegenerative diseases as neurofibrillar tangles. We have synthesized and structurally characterized a precisely patterned phosphotyrosine surface and establish(More)
Raman spectra of ordered carbon nanomaterials are quite sensitive to surface perturbations, including trace residues, structural defects and residual stress. This is demonstrated by a series of experiments with carbon nanotubes and graphene. Their spectra change due to subtle changes in preparation and attachment to the substrate and to each other.(More)
