Nanotechnology studied in heat transfer

Short description

The U.S. Air Force has awarded a $7 million grant to a University of Michigan-led team to apply nanotechnology to problems involved in heat transfer.

Article body

"The processes by which heat is transferred at interfaces between different materials are poorly understood," said Assistant Professor Kevin Pipe, who is leading the study for the Air Force Office of Scientific Research. "But in many systems, the ability to either efficiently transfer or block heat flow from one material to another is critically important to performance and reliability."

The research group includes nine scientists and engineers from the University of Michigan, Brown University and the University of California-Santa Cruz.

Pipe said his group will use ultrafast lasers in a special X-ray technique developed by University of Michigan Associate Professor David Reis that allows researchers to watch the vibrations of the atoms that carry heat energy across an interface.

Using nanotechnology, Pipe and his colleagues will re-engineer the surfaces of materials to regulate the flow of heat.

In addition to Pipe, the team includes Professors Rachel Goldman, Roberto Merlin, Humphrey Maris, Arto Nurmikko and John Kieffer; Assistant Professor Max Shtein; and Associate Professors David Reis and Ali Shakouri.

n-Surf Image Processor - Free evaluation

Short description

n-Surf is a new generation of software for analyzing and processing of images of surfaces obtained by Scanning Probe or Atomic Force Microscopes (SPM/AFMs).

n-Surf Image Processor.
n-Surf is a new generation of software for analyzing and processing of images of surfaces obtained by Scanning Probe or Atomic Force Microscopes (SPM/AFMs). This application was developed for high-quality visualization and easy processing of all types of images. To date, support for Veeco/DI, NT-MDT and MPRI files has been implemented.

Owing to the virtual main frame and other unique features, multidocument interface allows to work easily and concurrently with a variety of images.
You will enjoy freedom in manipulating different views of your document in the n - Surf environment.

This application uses all modern facilities of Windows 2000/XP, such as Thumbnails, Clipboard, Float toolbars, Contexts Help and others.

Superior printing quality will fit every user's requirements.

The basic concept of n-Surf is presentation of all images in the form of three views, namely, 2D, Bump and 3D, each having strengths and weaknesses. However, you have freedom in choosing the most workable one to solve your specific problems.

Researchers can use a lot of facilities and processing methods offered:

* Variety of filters such as Arithmetic mean, Median, Laplacian, Gaussian, High-pass, Low-pass, Sharpening, Prewitt, Scharr, Sobel, Roberts and others.
* Dilate and Erode morphological operations.
* Fourier transform and Autocorrelation.
* Roughness analysis, Height histogram and Bearing curve.
* Profiles.
* Special operations such as Jump elimination, Flatting and Plane fitting.

This list is by no means complete and will undergo replenishment in the future. At present n-Surf is constantly under development. Therefore there is always a room to implement specific suggestions of its customers. I would be happy to receive your remarks and proposals as to modification of this software.

Feel free to download the n-Surf 1.0 beta evaluation version.
