Enhanced thermoelectric figure of merit in edge-disordered zigzag graphene nanoribbons
We investigate electron and phonon transport through edge-disordered zigzag graphene nanoribbons based on the same methodological tool of nonequilibrium Green functions. We show that edge disorder…
Three-dimensional printing of hierarchical and tough mesoporous bioactive glass scaffolds with a controllable pore architecture, excellent mechanical strength and mineralization ability.
Charge transport in disordered graphene-based low dimensional materials
Two-dimensional graphene, carbon nanotubes, and graphene nanoribbons represent a novel class of low dimensional materials that could serve as building blocks for future carbon-based nanoelectronics.…
Direct low-temperature nanographene CVD synthesis over a dielectric insulator.
A facile chemical vapor deposition approach is reported in which nanographene and few-layernanographene are directly formed over magnesium oxide and can be achieved at temperatures as low as 325 degrees C.

It is identified that defects close to the edges and relatively small values of edge roughness preserve the quasi-ballistic nature of electronic transport, which presents a route of independently controlling electrical and thermal transport by judicious engineering of the defect distribution.
Charge transport in DNA-based devices
It is concluded that electrical transport is feasible in short DNA molecules, in bundles and networks, but blocked in long single molecules that are attached to surfaces.
Electronic structure of single DNA molecules resolved by transverse scanning tunnelling spectroscopy.
The energy spectrum of poly(G)-poly(C) DNA molecules deposited on gold is disclosed by using scanning tunnelling spectroscopy at cryogenic temperature and limited fluctuations in the I-V curves are observed and statistically characterized.
Chemiresistive biosensors based on carbon nanotubes for label-free detection of DNA sequences derived from avian influenza virus H5N1
Understanding the catalyst-free transformation of amorphous carbon into graphene by current-induced annealing
In the presence of a–C, graphene can grow from the borders of holes and form a seamless graphene sheet, a novel finding that has not been reported before and that is reproduced by the simulations as well.
Contact dependence of carrier injection in carbon nanotubes: an ab initio study.
It is suggested that the optimum metal-nanotube contact combines a weak hybridization with a large contact length between the metal and the nanotube.
