These cutting-edge nano technologies are only a sampling of what you’ll find in the July issue of Nanotech Briefs:

Nanotubes Hold Promise for Fuel Cells

Scientists at the National Institute of Standards and Technology demonstrated that titanium atoms can attach above the centers of single-walled carbon nanotubes. The quantum calculations and modeling conducted by the researchers revealed that each titanium atom can bond with four hydrogen molecules, a key capability to long-term efforts to develop fuel cells for future automobiles.

Nanoscale Photonic Technology

Scientists at Lawrence Berkeley National Laboratory and the University of California at Berkeley, working with free-standing, chemically synthesized nanowires and nanoribbons, have been able to guide pulses of laser light through a variety of complex structures. The researchers have demonstrated that these nanosized ribbons can serve as “waveguides” for channeling and directing the movement of light waves through circuitry.

Technique May Speed DNA Analysis

A “nano-printing” technique developed at MIT could enable the mass production of nano devices currently built one at a time. The most immediate candidate for this innovation is the DNA microarray, a nano device used to diagnose and understand genetic illnesses such as Alzheimer’s, viral illnesses such as AIDS, and certain types of cancer. In the new method, called Supramolecular Nano-Stamping (SuNS), single strands of DNA essentially self-assemble upon a surface to duplicate a nanoscale pattern made of their complementary DNA strands.

Single-Molecule Transistor Regulates Conductivity

A team of researchers from the National Institute for Nanotechnology of the National Research Council and University of Alberta, Canada, have designed and tested a new concept for a single-molecule transistor. They demonstrated that a single atom on a silicon surface could be controllably charged, while all surrounding atoms remain neutral. A molecule placed adjacent to that charged site is “tuned,” which allows electrical current to flow through the molecule from one electrode to another.
