Polymer composites reinforced by carbon nanotubes have been extensively researched for their strength and stiffness properties. Unless the interface is carefully engineered, poor load transfer between nanotubes (in bundles) and between nanotubes and surrounding polymer chains may result in interfacial slippage and reduced performance. Interfacial shear, although detrimental to high stiffness an...

Using molecular simulations the interaction between a noncharged nanoparticle and an ideal liquid-liquid interface is studied. The free energy profile as function of nanoparticle-interface separation is determined using Wang-Landau sampling. Comparison between the simulation results and macroscopic theories shows that the latter give a poor description of the free energy profile. In particular,...

The bonding strength and interfacial electronic properties of biphenyldimethyldithiol (HS– CH2–C6H4–C6H4–CH2–SH) adsorbed on Au(111) and polycrystalline cobalt are identifi ed from combined photoemission and inverse photoemission. In order to develop a better understanding of the thiol functional group to metal surface interaction, the stable orientation, bonding site, bonding strength and inte...

Wide bandgap semiconductors such as group III-nitrides and SiC are considered key materials for the fabrication of smaller, more reliable efficient power electronics. Fabrication robust durable devices requires an optimized design based on understanding interfacial adhesion properties constituent thin-film heterostructures. In this study, GaN/AlN layers grown Si substrates were investigated. Pa...

Silica nanoparticle/mesoporous silica composite films were prepared by direct mixing with mechanical stirring and thermal imidization. The structural morphology was elucidated by scanning electron microscopy and the surface of the film was imaged by atomic force microscopy. The functional groups and desorption process of the films were elucidated by Fourier transform infrared spectroscopy and t...
