MIT-News story on MEMSTiny 3-D chips - MIT researchers develop a new approach to producing three-dimensional microchips

Microelectromechanical systems, or MEMS, are small devices with huge potential. Typically made of components less than 100 microns in size — the diameter of a human hair — they have been used as tiny biological sensors, accelerometers, gyroscopes and actuators.

For the most part, existing MEMS devices are two-dimensional, with functional elements engineered on the surface of a chip. It was thought that operating in three dimensions — to detect acceleration, for example — would require complex manufacturing and costly merging of multiple devices in precise orientations.

Antidefects nanotubes

[Translation from French] Nanotubes to visualize defects of damaged airplane or wind turbine pieces:  such is the vision of some physicists at MIT, in the US. They used the fact that nanotubes heat up when in the path of an electric current. By integrating them into composite materials, such as those used in turbine blades, they manufactured parts whose defects can be detected by an infrared camera. In this picture, MIT’s letters have been engraved on a sample of this material, weakening it on some spots. The application of an electric current between the borders of the piece reveal its weaknesses: the red parts above and below the M. Those defects are visible because they disturb the current flow locally, concentrating it on the nanotubes which then heat up.

Catching cancer with carbon nanotubes

A Harvard bioengineer and an MIT aeronautical engineer have created a new device that can detect single cancer cells in a blood sample, potentially allowing doctors to quickly determine whether cancer has spread from its original site.

Seeing below the surface

Infrared themographic image of a nanoengineered composite heated via electrical probes (clips can be seen at bottom of image). The scalebar of colors is degrees Celsius. The MIT logo has been machined into the composite, and the hot and cool spots around the logo are caused by the thermal-electrical interactions of the resistive heating and the logo "damage" to the composite. The enhanced thermographic sensing described in the paper works in the same way.

Express Lanes for IONS

Actuators are devices that convert electrical energy into mechanical energy, such as the battery-powered device inside a cell phone that causes the phone to vibrate. When this process is reversed — when a device converts mechanical energy into electrical energy — the device is called an energy harvester, and that electrical energy is often stored for future use. An example would be a device inside a pacemaker that converts mechanical energy created by the motion of a pair of breathing lungs into electrical energy that can be used to charge the pacemaker’s batteries.

Nanostitching' Could Lead to Much Stronger Airplane Skins, More

MIT engineers are using carbon nanotubes only billionths of a meter thick to stitch together aerospace materials in work that could make airplane skins and other products some 10 times stronger at a nominal increase in cost.

Researchers make carbon nanotubes without metal catalyst

Carbon nanotubes - tiny, rolled-up tubes of graphite - promise to add speed to electronic circuits and strength to materials like carbon composites, used in airplanes and racecars. A major problem, however, is that the metals used to grow nanotubes react unfavorably with materials found in circuits and composites. But now, researchers at MIT have for the first time shown that nanotubes can grow without a metal catalyst. The researchers demonstrate that zirconium oxide, the same compound found in cubic zirconia "fake diamonds," can also grow nanotubes, but without the unwanted side effects of metal.

Nanotechnology: A new way to prevent flaws in composite materials

BECAUSE they are both strong and lightweight, composite materials made from carbon fibres are the darlings of engineers in the aerospace industry. Unfortunately, such materials deteriorate over time. Wind and rain attack the glue that sticks the layers of carbon fibres together. As a consequence, the layers peel away from one another. Many people have tried to solve this problem, without success. A new method aims to do so by stitching the carbon-fibre layers together...

"NanoBliss"
A Nano Art website by A. John Hart

Nanobliss is a gallery of visualizations of small-scale structures of carbon nanotubes and silicon, created by John Hart and collaborators. The dimensions of these structures range from nanometers to millimeters. The visualizations and the underlying fabrication techniques are new media for art, science, and architecture; and for promoting popular awareness and education about nanomaterials and related technologies. Forms under development include museum/gallery exhibitions and laboratory experiments, and advertising and informational pieces in scientific and popular literature.

Plastics: The NECST Generation
by Pontus Nordin

”Plastics.” The one-word career advice given to Dustin Hoffman’s young movie character Benjamin in the 1967 film The Graduate. Back then, aircraft were built from aluminium alloys. The first commercial carbon fibres had just been introduced as very expensive engineering materials for special military applications. Glass-fibre composites were still considered advanced, but did not have enough stiffness for structural applications in high-performance aircraft...
