Effective Charge of Adsorbed Poly(amidoamine) Dendrimers from Direct Force Measurements

Interaction forces between silica surfaces with adsorbed poly (amidoamine) (PAMAM) dendrimers were measured with the colloidal probe technique based on the atomic force microscope (AFM). At small separations, attractive non-DLVO forces are observed. These ...

13th EU–US Transport Task Force Workshop on transport in fusion plasmas

Ambrogio Fasoli

This report summarizes the contributions presented at the 13th EU-US Transport Task Force Workshop on transport in fusion plasmas, held in Copenhagen, Denmark, 1-4 September 2008. There were sessions on core heat and particle transport; core and edge momen ...

Statistics Of Prime Divisors In Function Fields

Robert Christopher Rhoades

We show that the prime divisors of a random polynomial in F-q[t] are typically "Poisson distributed". This result is analogous to the result in Z of Granville [1]. Along the way, we use a sieve developed by Granville and Soundararajan [2] to give a simple ...

Dispersion-Corrected Atom-Centered Potentials for Phosphorous

Ursula Röthlisberger, Ivano Tavernelli, I-Chun Lin

Dispersion-corrected atom-centered; potentials (DCACPs) for the element phosphorus were generated and tested for the BLYP, BP, and PBE generalized gradient approximations of the exchange-correlation functional. The accuracy and transferability of the DCACP ...

Analyzing 180 degrees turns using an inertial system reveals early signs of progression of Parkinson's disease.

Kamiar Aminian, Arash Salarian

Changes in turning are one of the early motor deficiencies in Parkinson's Disease (PD). We have proposed a system based on wearable, inertial sensors and a novel automatic analysis algorithm that can assess 180 degrees turns. Twelve patients in early stage ...

Nitrogen fixation at passivated Fe nanoclusters supported by an oxide surface: Identification of viable reaction routes using density functional calculations

Alfredo Pasquarello, Harald Brune, Zeljko Sljivancanin

Using density-functional calculations, we investigate the possibility of ammonia synthesis at supported Fe nanoclusters along catalytic routes closely resembling those in biological nitrogen fixation. To achieve similar catalytic conditions as at the activ ...

Molecular dynamics simulation of radiation damage in bcc tungsten

Molecular dynamics simulations of collision cascades in pure tungsten are performed to assess the primary damage due to irradiation. For short-range interaction the universal potential is used [1], while for long-range interaction, three different embedded ...

Interface free energy or surface tension: definition and basic properties.

Charles Pfister

Interface free energy is the contribution to the free energy of a system due to the presence of an interface separating two coexisting phases at equilibrium. It is also called interfacial free energy or surface tension. The content of the paper is 1) the d ...

Molecular dynamics simulation of radiation damage in bcc tungsten

Robin Schäublin

Molecular dynamics simulations of collision cascades in pure tungsten are performed to assess the primary damage due to irradiation. For short-range interaction the universal potential is used [J.F. Ziegler, J.P. Biersack, U. Littmark, The Stopping and Ran ...

Percolative properties of hard oblate ellipsoids of revolution with a soft shell

Peter Ryser, Claudio Grimaldi, Niklaus Johner, Gianluca Ambrosetti

We present an in-depth analysis of the geometrical percolation behavior in the continuum of random assemblies of hard oblate ellipsoids of revolution. Simulations were carried out by considering a broad range of aspect-ratios, from spheres up to aspect-rat ...
