Northwestern University engineers say that have finally found the key to practical use of carbon nanotubes (CNTs) in integrated circuits. Individual transistors made from CNTs are faster and more energy-efficient and reliable than those made from other materials.

The problem. But making the leap to wafer-scale integrated circuits (a microprocessor typically has a billion transistors) is a challenge. The process is incredibly expensive, often requiring billion-dollar cleanrooms to… read more

Russian physicists have invented an optical version of a transistor, based on a silicon nanoparticle. The research could lead to optical computers in the future.

Current computers are limited by the time needed to trigger a transistor — usually around 0.1 to 1 nanosecond (10−9 of a second). An optical transistor could work up to 1000 times faster — at picoseconds (10−12 of a second),… read more

A new origami “zippered tube” design that makes paper-based (or other thin materials) structures stiff enough to hold weight, yet can fold flat for easy shipping and storage could transform structures ranging from microscopic robots to furniture and even buildings.

That’s what researchers from the University of Illinois at Urbana-Champaign, the Georgia Institute of Technology, and the University of Tokyo suggest in a Proceedings of the National Academy ofread more

Lipid DNA origami may lead to advanced future nanomachines

Kyoto University scientists in Japan have developed a method for creating larger 2-D self-assembling DNA origami* nanostructures.

Current DNA origami methods can create extremely small two- and three-dimensional shapes that could be used as construction material to build nanodevices, such as nanomotors, in the future for targeted drug delivery inside the body, for example. KurzweilAI recently covered advanced methods developed by Brookhaven National Laboratory and  … read more

First known magnetic wormhole created

Could make MRIs more comfortable for patients and improve magnetic imaging

magnetic-wormhole ft

A wormhole* that can connect two regions of space magnetically has been created in the laboratory and experimentally demonstrated by physicists at Universitat Autònoma de Barcelona in Spain.

This is not a wormhole in space, as in the movie Interstellar. It’s a special design that transfers a magnetic field from one location in space to another in such a way that the process is magnetically… read more

New laser design could dramatically shrink autonomous-vehicle 3-D laser-ranging systems

September 4, 2015

This self-sweeping laser couples an optical field with the mechanical motion of a high-contrast grating (HCG) mirror. The HCG mirror is supported by mechanical springs connected to layers of semiconductor material. The red layer represents the laser’s gain (for light amplification), and the blue layers form the system’s second mirror. The force of the light causes the top mirror to vibrate at high speed. The vibration allows the laser to automatically change color as it scans. (credit: Weijian Yang)

UC Berkeley engineers have invented a new laser-ranging system that can reduce the power consumption, size, weight and cost of LIDAR (light detection and ranging, aka “light radar”), which is used in self-driving vehicles* to determine the distance to an object, and in real-time image capture for 3D videos.

“The advance could shrink components that now take up the space of a shoebox down to… read more

A user-friendly 3-D printing interface for customizing designs

Design tool lets novices do in minutes what would take experts in computer-aided design hours
September 4, 2015

A new Web-based interface for design novices allows a wide range of modifications to a basic design — such as a toy car or a black-and-white "yin-yang" cup — that are guaranteed to be both structurally stable and printable on a 3-D printer. (credit: Courtesy of the researchers (edited by MIT News))

Researchers at MIT and the Interdisciplinary Center Herzliya in Israel have developed a system that automatically turns CAD files into visual models that users can modify in real time, simply by moving virtual sliders on a Web page. Once the design meets their specifications, they can hit the print button to send it to a 3-D printer.

Currently, 3-D printing an object from any but the simplest designs requires… read more
