Quantum dots are semiconducting, nanoscale clusters that show electronic characteristics distinct from both bulk-scale materials and single molecules. Their special characteristics make quantum dots attractive for a broad range of potential applications, including photovoltaics and nanoscale transistors. The size and shape of quantum dots impact electrical properties and can therefore be used to tune the [...]

Recently we pointed at a Forbe’s interview with Eric Drexler, in anticipation of his pending new book Radical Abundance. The book has shipped, and Drexler’s tour schedule now includes a few stops on the coasts of the U.S: New York: May 6th Los Angeles: May 8th & 9th Seattle: May 9th Find exact times and [...]
In anticipation of Eric Drexler’s new book, Forbes contributor Bruce Dorminey interviews him about the meaning of nanotechnology and its revolutionary prospects. Selected excerpt: … In what fields would APM cause the most pronounced economic disruption and the collapse of global supply chains to more local chains? The digital revolution had far-reaching effects on information [...]
A demonstration that most fundamental biological processes can be implemented in a test tube as efficiently as in live bacteria provides synthetic biology the tools to create a ‘new industrial revolution’, which may or may not lead to more general molecular manufacturing.
Templates made from polymer nanofibers enable the formation of long-lived silicon nanostructures that store ten times as much charge as do graphite battery terminals.
Doping carbon nanotubes with boron while they are being formed produces a novel molecular architecture formed by boron induced kinks and linkages. These nanosponges can be used repeatedly to absorb and retrieve or burn spilled oil.
Composites made with small amounts of multi-walled carbon nanotubes improve wind turbine blades by reducing mass while retaining strength.
In a lecture at Oxford Eric Drexler argued that atomically precise manufacturing will be the next great revolution in the material basis of civilization, and discussed how we can establish reliable knowledge about key aspects of such technologies.
A bacterial virus called M13 was genetically engineered to control the arrangement of carbon nanotubes, improving solar-cell efficiency by nearly one-third.
Zyvex Technologies announced that its 54-foot boat named Piranha completed a rough-weather sea test near Puget Sound in the Pacific Ocean, demonstrating record fuel efficiency.
Will proposals to establish criteria for green nanotechnology foster growth of nanotechnology innovation?
A step toward advanced nanotechnology has been achieved by using attachment to a surface and confinement by surrounding molecules to make two molecules react to form a product that would not form if they were free to react in solution.
Combining nanoparticles and graphene with platinum produces more efficient and durable catalyst for fuel cells.
A new laser for nanotechnology could lead to more powerful microscopes, faster computers, and more efficient solar energy collectors.
Graphene supercapacitor stores as much energy per unit mass as nickel metal hydride batteries but charges in minutes.
Congressman Commends Focus on Job Creation in National Nanotechnology Initiative Draft Strategic PlanPosted by Jim Lewis on December 6th, 2010
Research and Science Education Subcommittee Chairman Dan Lipinski (IL-03) expressed his strong support for the National Nanotechnology Initiative’s draft Strategic Plan, in particular its focus on ensuring that America’s substantial investment in nanotech research and development is turned into new companies, products, and jobs.
High-performance metal-insulator-metal (MIM) diodes made possibe by controlling quantum mechanical tunneling through an ultrathin insulator could change modern electronics.
US National Nanotechnology Initiative wants your comments on its strategic plan.
Hogg and Freitas provide a theoretical analysis of the power constraints when nanorobots rely entirely on ambient bloodstream oxygen and glucose and identify aspects of nanorobot design that significantly affect available power.
An energy cell containing a lead zirconate titanate cantilever coated with a carbon nanotube film uses nanotechnology to produce electricity from scavenged light and thermal energy.
