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.
The Space Studies Institute will hold Space Manufacturing 14 on Oct. 30-31, 2010 at NASA Ames here in Silicon Valley. Topics to be covered include: Session 1: Space Transportation Architecture Session 2: Closed Environment Life Support Systems Session 3: Robotics and Space Manufacturing Session 4: Extraterrestrial Prospecting Session 5: Engineering Materials from Non-Terrestrial Resources Session 6: Space [...]
The U.S. President’s Council on Advisors on Science and Technology requested public input on a number of manufacturing topics including “molecular-level, atomically precise production.” Foresight joined with our sister organization IMM to produce a statement on Atomically Precise Manufacturing, now posted on the OpenPCAST site, with public voting and commenting still continuing, so join in the [...]
Rob Freitas has a new paper up: Robert A. Freitas Jr., “Diamond Trees (Tropostats): A Molecular Manufacturing Based System for Compositional Atmospheric Homeostasis,” IMM Report 43, 10 February 2010 Abstract. The future technology of molecular manufacturing will enable long-term sequestration of atmospheric carbon in solid diamond products, along with sequestration of lesser masses of numerous [...]
When I woke up this morning, it was nine degrees below zero, Celsius. It’s solidly overcast here, and what’s more, this time of year the sun doesn’t get much more than 20 degrees above the horizon — in the middle of an all-too-short day. My house has a footprint of about 200 square meters. At [...]
(Atomic Age, that is.) From the University of Chicago Library site: On December 2, 1942, scientists at the University of Chicago produced the world’s first self-sustaining nuclear chain reaction in a nuclear pile constructed in a squash court beneath the West Stands of Stagg Field, the University’s athletic stadium. This experiment, crucial to the control [...]
Over at Nanoclast, Dexter Johnson writes: It seems when nanotech is applied to photovoltaics it can either boost their efficiency to new heights or it can cheapen their manufacturing process. But it never seems to provide a solution to both of these. It’s always a tradeoff: increased efficiency but difficult manufacturing processes or a cheaper [...]
Technology Review: Self-Cleaning, Super-Absorbant Solar Cells. Amorphous-silicon solar cells patterned with nanoscale domes absorb more light–and shed water and dust.
Josh Hall, on his way to catch a plane, sends us this news from Technology Review’s Katherine Bourzac: A California company is using silicon ink patterned on top of silicon wafers to boost the efficiency of solar cells. The Sunnyvale, CA, firm Innovalight says that the inkjet process is a cheaper route to more-efficient solar power. [...]
Previous in series: VTOL So, how close are we to flying cars? For specificity, let’s pick a technological bar to hurdle that answers most of the objections to the concept we’ve seen as comments on the previous posts: It should be relatively high-powered compared to current light craft. It should be STOVL for safety and [...]
What will your car run on in 2020 or 2030? What form of energy storage and transmission will allow intermittent energy sources, such as wind and solar, to be a viable input to the economy? There’s a good chance, of course, that cars will still run on gasoline — its demise has been predicted early [...]
Here’s a University of Rochester press release from 2006: Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black. The process, using an incredibly intense burst of laser light, holds the promise of making everything from fuel cells to a space telescope’s [...]
