Elastic properties of chemically derived single graphene sheets

Klaus Kern, Marko Burghard

The elastic modulus of freely suspended graphene monolayers, obtained via chemical reduction of graphene oxide, was determined through tip-induced deformation experiments. Despite their defect content, the single sheets exhibit an extraordinary stiffness ( ...

Effect of metal elements in catalytic growth of carbon nanotubes

Alfredo Pasquarello, Oleg Yazyev

Using first-principles calculations, we model the chemical vapor deposition (CVD) growth of carbon nanotubes (CNT) on nanoparticles of late-transition (Ni, Pd, Pt) and coinage (Cu, Ag, Au) metals. The process is analyzed in terms of the binding of mono- an ...

The role of nanostructure in the wetting behavior of mixed-monolayer-protected metal nanoparticles

Nicola Marzari, Francesco Stellacci, Munish Sharma

Self-assembled monolayer-protected nanoparticles are promising candidates for applications, such as sensing and drug delivery, in which the molecular ligands' interactions with the surrounding environment play a crucial role. We recently showed that, when ...

Pores in Nanostructured TiO2 Films. Size Distribution and Pore Permeability

Ulf Anders Hagfeldt

Nanoporous films of cryst. anatase with intended application in dye-sensitized photovoltaic cells were studied by NMR cryoporometry, NMR diffusiometry, electron microscopy, and x-ray diffraction. The nanoparticles from which the films were subsequently sin ...

Structural and electronic properties of an abrupt 4H-SiC(0001)/SiO2 interface model: Classical molecular dynamics simulations and density functional calculations

Alfredo Pasquarello, Peter Broqvist, Fabien Devynck

Using a density functional approach, we study structural and electronic properties of the 4H(0001)-SiC/SiO2 interface. Through the sequential use of classical and ab initio simulation methods, we generate an abrupt model structure which describes the trans ...

Tunable PDMS Nanostructured Ssurfaces Through Replication of Nanoscale Topography of Diblock Copolymer Micellar Thin Films

Jürgen Brugger, Sivashankar Krishnamoorthy, Harry Heinzelmann, Raphaël Pugin

This report will focus on creation of nanostructured PDMS surfaces with tunable feature dimensions and periodicities, and the use of these surfaces to study the influence of nanotopography on cell-substrate interactions. The topography on surfaces is known ...

Abrupt model interface for the 4H(1000)SiC-SiO2 interface

Alfredo Pasquarello, Fabien Devynck

Through the sequential use of classical molecular dynamics and first-principles relaxation methods, we generate an abrupt model interface for the 4H(0001)SiC-SiO2 interface showing regular structural parameters without any coordination defect. The bond den ...
