Overview of Overlapping Bio and Nano Technologies

Iyer S., LANL, US

“What is the connection between nanoscience and biology?” “What are biologists doing at Nanotech 2004 and why do you have so many “bio” related sessions?” “So biologists are also jumping on the nanoscience bandwagon.” These [...]

Chemically Functionalized Clay Epoxy Nanocomposites for Aerospace Applications

Balakrishnan S., Raghavan D., Howard University, US

Reinforcement of polymeric resin with nanoclay platelets has resulted in lightweight materials with enhanced mechanical and thermal properties. The selection of clay as reinforcing material is extremely appealing because of cost, high thermal inertness, and [...]

Next Generation Aerospace Composites Through Nanotechnology

Yebassa D., Balakrishnan S., Raghavan D., Howard University, US

Polymeric nanocomposites are a relatively new class of materials obtained by dispersing inorganic layered silicates in polymer matrix. Generally well-dispersed exfoliated morphology of clay platelets in nanocomposite is sought with the expectation that this would [...]

Optimizing Processing Conditions to Influence the Morphology of Nanocomposite

Raghavan D., Balakrishnan S., Gebrekristios Y., Howard University, US

In recent years, the area of nanocomposites has received considerable attention with the expectation that nanotechnology can lead to lighter, better materials for engineering applications. For example, the attractiveness of polymer-clay nanocomposites resides in the [...]

Low K Carbon Films Deposited in Low Frequency Discharge for Sub-micron Devices

Kosarev A., Torres A., Zuniga C., Institut National for Astrophysics, Optics and Electronics, MX

An interconnect delay begins to dominate total device delay time and consequently, operation rate at sub-micron (

A Novel Method for the De-Embedding of S-Parameters of Double Heterojunction d-doped PHEMTs – Modeling and Measurements

Rao R.V.V.V.J., Joe J., Chia Y.W.M., Ang K.S., Wang H., Ng G.I., National University of Singapore, SG

A simple and accurate method for extracting small-signal signal equivalent circuit for double heterojunction d-doped PHEMTs was developed. The circuit elements were extracted from the S-parameters of PHEMTs. Parasitic inductances Lg, Ld and Ls were [...]
