Turbocharge Your Scientific Applications with Scripting

Online Presentations | 29 Apr 2004 | Contributor(s): Michael McLennan

Scientific applications are built with great care and attention to the core simulation algorithms, often with some input/output added as an afterthought. Instead, you can create a much more powerful tool with little extra effort by replacing the usual "main" program with an embedded...

Nanotechnology 101 Lecture Series

Series | Contributor(s): Joseph M. Cychosz (editor)

Welcome to Nanotechnology 101, a series of lectures designed to provide an undergraduate-level introduction to nanotechnology. In contrast, the Nanotechnology 501 series offers lectures for the graduate-level and professional audiences.

Nanosystems Biology

Online Presentations | 10 Sep 2004 | Contributor(s): James R. Heath

As we enter the 21st century, we stand at a major inflection point for biology and medicine-the way we view and practice these disciplines is changing profoundly. These changes are being driven by systems biology, a new approach to biology, and which will increasingly transform medicine from...

Electronic Transport in Semiconductors (Introductory Lecture)

Online Presentations | 25 Aug 2004 | Contributor(s): Mark Lundstrom

Welcome to the ECE 656 Introductory lecture. The objective of the course is to develop a clear, physical understanding of charge carrier transport in bulk semiconductors and in small semiconductor devices.The emphasis is on transport physics and its consequences in a device context. The course...

Vertically Aligned Carbon Nanotube for Interconnects and Nanoelectrode Based Biosensors

Online Presentations | 15 Apr 2004 | Contributor(s): Jun Li

In the past few years, tremendous progress in the growth of carbon nanotubes (CNTs) has been made, which enabled the fabrication of various CNT devices for applications in electronics, biomedical techniques, and chemical/biological sensors. We have established a process to grow vertically aligned...

Multiscale Modeling of the Mechanical Behavior of Polymer-Based Nanocomposites

Online Presentations | 25 Mar 2004 | Contributor(s): Catalin Picu

Polymers filled with nanoscale fillers (carbon nanotubes or nanoparticles) exhibit enhanced properties compared with the neat polymer and with the polymer filled with micron-sized fillers at same volume fraction. Most interestingly, combinations of exceptional properties may be obtained as, for...

Process Variation: An Evalution of Carbon Nanotube Transistor Field Effect Transistors

Presentation Materials | 16 Aug 2004 | Contributor(s): Sergio Urban, Alvin Lacson, Louis Bonhami

Process variation is the observed deviation of device parameters in mass production processes. As the critical dimensions of today's MOSFET's are continously decreasing, process variation is becoming an increased problem.

Biostimulation of Human Endothelial Cells Using Applied Photonic Energy

Presentation Materials | 16 Aug 2004 | Contributor(s): Emile Rochen

Endothelial cells can be envisioned as the circulatory gateways between the bloodstream and bodily tissues. These cells, which line the interior of our arteries and veins, provide a critical exchange function within the body.

Modification of Si(111) Surfaces using Self - Assembled Monolayers (SAMs) for Electrochemical and AF

Presentation Materials | 16 Aug 2004 | Contributor(s): Rosangelly Flores Pérez

Recent researchers in the electrical engineering field are using self-assembled monolayers techniques with aryldiazonium salts solutions to build nanoelectronic devices. This innovation can explain the molecular conductivity and the chemical covalent bonds between π- conjugated orbitals of the...

Efficient UDP Haptic Device Communication

Presentation Materials | 16 Aug 2004 | Contributor(s): Daniel Wilhelm

The User Datagram Protocol (UDP) is a robust method for communicating with haptic devices across a Local Area Network (LAN), enabling fast Ethernet transmission and remote operation.

Self-Assembled Monolayer of DNA Microarrays

Presentation Materials | 16 Aug 2004 | Contributor(s): Joanny Tam

Conductivity experiments with DNA have already been performed. With this in mind, we experimented using the charge transport of DNA to receive signals about detection of similar DNA sequences of another species through the linking of complementary ssDNA on chips; subsequently, these methods can...

Hydrodynamic Separation of Micron-sized Particles through Magnetization

Presentation Materials | 16 Aug 2004 | Contributor(s): Michael Benko

Many assays and lab-on-a-chip projects require the use of uniform magnetic particles. Creating magnetic particles of uniform size and magnetization is a difficult task. The next best alternative is to make a distribution of particles and separate them.
