The average charges of fragment ions were theoretically studied for 1 MeV/atom C n + ( n = 1 – 10 ) cluster ions penetrating carbon and aluminum foils. Here the clusters are assumed to be in linear-chain structures, and to have a random orientation and to be exploded via coulom...
The mechanism of action in electronics involves the high electrical conductivity of Carbon Nanotubes, which allows for efficient charge transport and improved device performance. Materials Science: Carbon Nanotubes have also found applications in materials science. They can be used as reinforcement agents...
measures 1.17 Å. The negative of the crystal orbital Hamilton population integrated to the Fermi level (-iCOHP), which can be used to quantify the bond strength, is calculated to be 5.11 eV for this bond. The distance between the hydrogen atom bonded to ...
In contrast to Ni, the growth on Cu bases on a self-limiting surface adsorption process, attributed to the low solubility of C atoms in Cu [47,48,49]. The decomposed carbon atom nucleates on top of the metallic surface forming ordered crystals subsequently growing a two-dimensional carbon ...

which can also act a terminal atom[74]. For a given precursor, by increasing the pyrolysis temperature theheteroatom contentis lowered. This is another factor that promotes increased order at higher processing temperatures, in addition to greater mobility of the remaining molecules. Annealing temperatu...
Electrical properties of carbon structures : carbon nanotubes and graphene nanoribbons Graphene is a one-atom thick sheet of graphite which made of carbon atoms arranged in a hexagonal lattice. Carbon nanotubes and graphene nanoribbons can be viewed as single molecules in nanometer scale. Carbon nanotu...
The chemical structure of reagents and reactions in the above examples are indeed very different (Figure S1). In order to analyze them collectively, in Fig. 1b the change of the formal oxidation number of the atom at the reaction site is plotted along the reaction coordinate. While in redox...
(40.78 H2 s−1at 100 mV) is better than that of a graphene-supported single-atom catalyst with a similar Pt loading, and comparable to a commercial Pt/C catalyst with 20 wt% Pt. First-principle calculations suggest that a tip-enhanced local electric field at the Pt site on...
