Quantum phase transitions in effective spin-ladder models for graphene zigzag nanoribbons
, 2017 We examine the magnetic correlations in quantum spin models that were derived recently as effective low-energy theories for electronic correlation effects on the edge states of graphene nanoribbons.

Graphite nanoribbons prepared by the graphitization of poly(4-phthalimide) nanoribbons
TANSO, 2014 Abstract Highly crystalline polyphthalimide nanoribbons were prepared by the reaction-induced crystallization of oligomers during solution polymerization. Polymerization of 1-hexyl 4-aminophthalate and 2-hexyl 4-aminophthalate was carried out at 330 °C in alkyl naphthalene oil.

Advanced Science, EarlyView.Imidazolium PIL nanoparticles, as an N‐rich template and morphology director, enable a colloidal self‐nitriding route to TMNs (VN, Mo2N) within controlled solid/hollow carbon architectures. As sulfur hosts/additives, TMNs accelerate Li–S redox kinetics and support high‐loading cathodes.

Conductance quantization and transport gap in disordered graphene nanoribbons
, 2009 We study numerically the effects of edge and bulk disorder on the conductance of graphene nanoribbons. We compute the conductance suppression due to localization induced by edge scattering. We find that even for weak edge roughness, conductance steps are

Berry's Phase for Standing Wave Near Graphene Edge
, 2010 Standing waves near the zigzag and armchair edges, and their Berry's phases are investigated. It is suggested that the Berry's phase for the standing wave near the zigzag edge is trivial, while that near the armchair edge is non-trivial.
