Preparation of boron-doped hydrothermal carbon from glucose for carbon paste electrode
(Carbon, 2015)
Boron doped hydrothermal carbon microspheres were synthesized by introducing boric acid into glucose precursor solution to obtain boron concentration from 0.1 to 1 wt. %. Following hydrothermal treatment, samples were ...
Planar versus three-dimensional growth of metal nanostructures at graphene
(Carbon, 2016)
Employing density functional theory we studied microscopic mechanisms governing initial stages of growth of three selected metals (Li, Ti and Ca) on graphene. Tendency towards planar or three-dimensional (3D) growth is ...
The production of porous glassy carbon membranes from swift heavy ion irradiated Kapton
(Carbon, 2011)
A porous glassy carbon membrane was obtained by first producing ion tracks in a polymeric Kapton film by irradiation with high energy krypton or xenon ions. Pores are formed by selective chemical etching along the ion ...
Porous carbon thin films for electrochemical capacitors
(Carbon, 2013)
Activation effects on carbon films, derived from commercial aromatic polyimide films (Kapton, DuPont), in CO2 atmosphere at 1203 K on capacitance properties were studied. Two thicknesses of polyimide films were used: 7 and ...
Interband plasmons in supported graphene on metal substrates: Theory and experiments
(Carbon, 2016)
We present a theoretical modeling of the energy-loss spectroscopy data for monolayer graphene (MLG) supported by Pt(111), Ru(0001) and Ni(111) substrates. To reproduce the experimental loss function, we have used a ...
The role of steam treatment on the structure, purity and length distribution of multi-walled carbon nanotubes
(Carbon, 2015)
Purification and shortening of carbon nanotubes have attracted a great deal of attention to increase the biocompatibility and performance of the material in several applications. Steam treatment has been employed to afford ...
Modification of glassy carbon properties under low energy proton irradiation
(Carbon, 2011)
Glassy carbon plates were irradiated with 15 key H(+) ion-beam in the fluence range of 1 x 10(16)-3 x 10(18) ion cm(-2). The influence of ion irradiation on surface morphology and topology was examined by scanning electron ...
The effect of boron incorporation on the structure and properties of glassy carbon
(Carbon, 2011)
Boron was introduced into glassy carbon by chemical modification and by irradiating the precursor polymer with boron ions. Using chemical modification, a polymer with uniform distribution of boron in the bulk was obtained, ...
Binding of atomic oxygen on graphene from small epoxy clusters to a fully oxidized surface
(Carbon, 2013)
We used ab initio calculations based on density functional theory (DFT) to investigate the binding of atomic oxygen on graphene, considering adsorption structures with sizes varying from sub-nanometric clusters to infinite ...
Linear hydrogen adsorbate structures on graphite induced by self-assembled molecular monolayers
(Carbon, 2012)
Combined scanning tunnelling microscopy measurements and density functional theory calculations reveal a method to induce linear structures of hydrogen adsorbates on graphite by covering the surface with a self-assembled ...
