Nanotribology and Lubrication at Nanoscale: Molecular Dynamics Simulation Studies

Jabbarzadeh A., The University of Sydney, AU

Increasing technological advances to make devices and processes at the nanoscale, have made it necessary to effectively minimize the friction and adhesion of moving mechanical assemblies, such as those in micro- or nano-electromechanical (MEMS/NEMS) devices. [...]

Directed Self Assembly: a Novel, High Speed Method of Nanocoating Ultra-thin Films and Monolayers of Particles

Powch G.A., Jain A.R., VersuFLEX Technologies LLC, US

A novel, practical fluidic method is presented for coating ultra-thin, ultra-uniform layers and realizing self-assembled monolayers of particles, into nanoscale in atmosphere and room temperature at rates scalable to web processes at >4 m/min. A [...]

Octadecylphosphonic acid Langmuir-Blodgett films and their modification by hyperthermal hydrogen projectile

Dey R., The university of waterloo, CA

We report on surface modification with hyperthermal hydrogen induced cross-linking (HHIC) technology on uniform and well-ordered octadecylphosphonic acid (OPA) Langmuir-Blodgett (LB) films on several surfaces, and on surface characterizations of its properties. The hyperthermal hydrogen [...]

Odd-Even Effect in Self Assembly and Phase Transition of Alkanethiols Monolayers (SAMs) on Au (111) Surfaces

Ramin L., Jabbarzadeh A., The University of Sydney, AU

Molecular dynamic simulations were conducted to predict the structural properties of n-alkanethiols CH3(CH2)n-1SH (n=4-22) self assembled monolayers (SAMs) on Au (111) surfaces. We studied the effects of chain length on the structural properties, including orientation [...]

Biocompatible Nanomembranes based on PEGylation of Cross-Linked Self-Assembled Monolayers

Meyerbroeker N., Eck W., Zharnikov M., University of Heidelberg, DE

We present a novel ultrathin and biocompatible membrane based on highly cross-linked and subsequently PEGylated self- assembled monolayers. These layers can be removed from their substrates and freely suspended over TEM grids. Possible applications of [...]

Iron oxide nanoparticles reinforced self-assembled monolayers of cystamine for use in enzymatic biosensor development

Newati S.J., Singh V.M., Sachdeva S., Khan R.A., Manav Rachna International University (MRIU), IN

The immobilization of biomolecules on solid support is crucial component in fabrication of biosensors. The self assembled monolayers (SAM) can be used for fabrication of the biosensor-component that allows chemically reactive functional group manipulations for [...]

Vapor Deposited Nanolaminates

Kobrin B., Grimes M., Dangaria N., Applied Microstructures, Inc., US

We present the latest developments in nanocoatings deposition technology, realized using Molecular Vapor Deposition (MVD®) method. Multi-layer nanolaminates of metal oxides (alumina, titania, silicon oxide, …etc.) and self-assembled monolayers (SAMs) sequentially deposited using an automated [...]
