Methods of colloid vibration imaging for characterisation of nano-particle suspensions

Wang M., Hosseini M., Bramson L., Khan J.I., University of Leeds, UK

This paper addresses various aspects in the development of the new imaging technique, colloid vibration potential imaging. Two theoretical models are introduced, including an extended (2D) slab model and a 3D electric dipole model. These [...]

Solid-state nanopores: a new tool for biomedical diagnostics

Khongkow M., Instuli E., Ivanov A., Albrecht T., Edel J.B., Imperial College London, UK

In this work, we present first results from the experimental implementation of an electrode/nanopore architecture with the aim of characterizing ion and DNA transport under the influence of a local alternating electric field. This includes [...]

Wetting and Hydrophobicity of Nanoscale Systems with Impurities

Gonnet P., Zimmerli U., Walther J.H., Werder T., Koumoutsakos P., ETH Zürich, CH

Molecular dynamics simulations are performed to study the influence of surface and fluid impurities on water-carbon interfaces. In order to quantify these interactions we consider both the canonical problem of wetting of a doped flat [...]

Real Time Kinetic Measurements of Silver Nanocluster Growth

Mercado L., Castro M.E., Castro W., Vicuña E., Briano J.G., Ishikawa Y., Irizarry R., Solá L., Castro M.E., Castro W., University of Puerto Rico, US

Metallic clusters of noble metals are of tremendous technological importance due to their conduction properties, size, low reactivity and optical properties. Clusters containing as few as two and four silver atoms have been prepared in [...]
