Fate of a Graphene Flake: A New Route toward Fullerenes Disclosed with Ab Initio Simulations

Wanda Andreoni, Fabio Pietrucci

The top-down formation of a fullerene from a graphene flake is investigated via extensive ab initio molecular dynamics simulations in the range 300-3000 K, accelerated by metadynamics. Topological (SPRINT) coordinates are used to ensure a prejudice-free ex ...

Reaction dynamics of in aqueous amines from ab initio molecular dynamics: 2-amino-2-methyl-1,3-propanediol (AMPD) compared to monoethanolamine (MEA)

Wanda Andreoni, Fabio Pietrucci, Changru Ma

We present Car-Parrinello molecular dynamics simulations-combined with metadynamics-of the reactions accompanying the capture of in an aqueous amine solution. The selected amine is 2-amino-2-methyl-1,3-propanediol, which has been investigated experimentall ...

Atomic Oxygen Chemisorption on Carbon Nanotubes Revisited with Theory and Experiment

Wanda Andreoni, Fabio Pietrucci, Alessandro Curioni

Density-functional-theory based calculations of two single-walled carbon nanotubes of different chirality settle open issues on the sidewall chemisorption of atomic oxygen at low concentrations. Ether groups are the thermodynamically favored configurations ...

The response of single-walled carbon nanotubes to NO2 and the search for a long-living adsorbed species

Wanda Andreoni, Fabio Pietrucci

Contact-passivated sensor devices allow one to measure the response of individual ultraclean single-walled carbon nanotubes to 1 ppm NO2, and show that the activation energies for desorption from nanotubes of diameters in the 1.5-3.5 nm range are of the or ...

Characterizing and Understanding Divalent Adsorbates on Carbon Nanotubes with Ab Initio and Classical Approaches: Size, Chirality, and Coverage Effects

Wanda Andreoni, Fabio Pietrucci, Alessandro Curioni

The study of oxygen chemisorption on single-walled carbon nanotubes generally relies on simple atomistic models and hence hampers the possibility to understand whether nanotube size or adduct concentration have a role in determining the surface adsorbate i ...
