Vibration damping/dynamic properties of CNT-reinforced composite structures

Kireitseu M.V., Rolls-Royce Centre in Damping, the University of Sheffield, UK, UK

Energy dissipation (damping) in structures/materials is important as it reduces resonant amplitudes/noise levels giving enhanced integrity and life cycle behavior. If we then go to the nanoscale, the damping levels/dynamics of materials are mostly unknown [...]

Design and Manufacturing Concepts of Nanoparticle-reinforced Aerospace Materials

Kireitseu M.V., Tomlinson G.R., Basenuk V., Rolls-Royce Centre in Damping, the University of Sheffield, UK

Material and Fan Blade Design Concepts shown in fig. 1 are introduced as follows: 1) CNT-reinforced micro-balloons to be used to create syntactic foam (an two-part epoxy adhesive filled with micro-balloons) such that the density [...]

Cermet Ceramic Coating on Diamond Dresser for In-Situ Dressing of Chemical Mechanical Planarization

Sung J.C-M, Kan K., Kinik Company, TW

In recent years, copper circuitry has been replacing aluminum wires and tungsten via as the dominant interconnections. The polishing of copper circuitry requires using highly acidic solution (e.g. pH = 4) and with strong oxidizing [...]

Durable Anti-Stiction Coatings by Molecular Vapor Deposition (MVD)

Kobrin B., Chinn J., Ashurst R.W., Applied Microstructures, Inc., US

Development of new SAM coatings using a “sequential” vapor technique which can be deposited on almost any substrate material and withstand harsh environments is reported. Technical benefits for the improved surface modification method called Molecular [...]

Structure and Rheology of Supercritical Carbon Dioxide Exfoliated Polymer Nanocomposites

Serhatkulu G.K., Horsch S.E., Kannan R., Gulari E., Wayne State University, US

A major technological barrier to achieving superior properties of nano-structured composite materials is the difficulty of dispersing fillers uniformly in a host matrix. The existing nanocomposite manufacturing processes achieve property improvements through chemical modifications of [...]

Modeling and Simulation of Tubular Nanowires

Buldum A., The University of Akron, US

Metallic nanowires have attracted great interest due to their interesting low-dimensional physics and due to possible future technological applications. Most of the previous investigations were related with quantum point contacts and atomic scale nanowires. Recently, [...]
