Next Generation Antennas And Lenses Use Self-assembling Nanocubes
2012-06-13 20:14:18

Researchers at the University of California, San Diego Jacobs School of Engineering have developed a technique that enables metallic nanocrystals to self-assemble into larger, complex materials for next-generation antennas and lenses. The metal nanocrystals are cube-shaped and, like bricks or Tetris blocks, spontaneously organize themselves into larger-scale structures with precise orientations relative to one another.  Their findings were published online June 10 in the journal Nature...

Expanding on previous work with engines traveling on straight tracks, a team of researchers at Kyoto University and the University of Oxford have successfully used DNA building blocks to construct a motor capable of navigating a programmable network of tracks with multiple switches. The findings, published in the January 22 online edition of the journal Nature Nanotechnology, are expected to lead to further developments in the field of nanoengineering. The research utilizes the technology...

A new biomaterial designed for repairing damaged human tissue doesn't wrinkle up when it is stretched. The invention from nanoengineers at the University of California, San Diego marks a significant breakthrough in tissue engineering because it more closely mimics the properties of native human tissue. Shaochen Chen, professor in the Department of NanoEngineering at the UC San Diego Jacobs School of Engineering, hopes future tissue patches, which are used to repair damaged heart walls, blood...

In a complex feat of nanoengineering, a team of scientists at Kyoto University and the University of Oxford have succeeded in creating a programable molecular transport system, the workings of which can be observed in real time. The results, appearing in the latest issue of Nature Nanotechnology, open the door to the development of advanced drug delivery methods and molecular manufacturing systems. Resembling a monorail train, the system relies on the self-assembly properties of DNA origami...

Nanoscience  has the potential to play an enormous role in enhancing a range of products, including sensors, photovoltaics and consumer electronics.  Scientists in this field have created a multitude of nano scale materials, such as metal nanocrystals, carbon nanotubes and semiconducting nanowires. However, despite their appeal, it has remained an astounding challenge to engineer the orientation and placement of these materials into the desired device architectures that are...

A University of Colorado at Boulder team has developed a new method of shrinking the size of circuitry used in nanotechnology devices like computer chips and solar cells by using two separate colors of light.Like current methods in the nanoengineering field, one color of light inscribes a pattern on a substrate, said CU-Boulder Assistant Professor Robert McLeod of the electrical, computer and energy engineering department. But the new system developed by McLeod's team uses a second color to...


Word of the Day
humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
