The US National Science Foundation announced a new grant program to develop and apply next-generation networking to advance nanotechnology and other emerging technologies to meet important national needs.
A small, interactive group of invited experts gathered in Palo Alto recently to discuss prospects for revolutionary advances in energy storage, transmission, and generation through nanotechnology.
A nanoparticle that self-assembles from porphyrin, cholic acid, amino acids, and polyethylene glycol is a promising vehicle for delivering both imaging agents and cancer drugs to tumors.
Register by Sept. 5 to attend a Proposers Day webinar on either Sept. 9 or 11 to learn the technical objectives of DARPA’s new “Atoms to product: Aiming to make nanoscale benefits life-sized” program.
Photovoltaics are an interesting case where atomic precision is not necessary to achieve potentially dramatic global impacts. Even an “ok efficiency” device that is easy to manufacture with reduced environmental hazard could have significant beneficial effects on energy resources and on device fabrication processes (which could, in turn, contribute to developments toward APM). The struggle [...]
Rice University’s breakthrough nanoporous silicon oxide technology for resistive random-access memory (RRAM) appears poised for commercialization.
Study shows more than 500 firms involved in nanobiotechnology, which is expected to soon triple in size. Research points to the importance of broad networks and deep collaborations.
Just when it seemed like debate over the National Nanotechnology Initiative was a thing of the past (see Foresight’s disappointment in 2008 here), disagreements regarding re-authorization and budget cuts are prompting politicians and researchers to take a detailed look at what the program supports and what it is achieving. Witnesses to the House Research Subcommittee [...]
Carbon-containing functional groups decorating carbon nanotubes decompose upon heating on copper foil to form a nanotube-reinforced graphene with novel properties that mimic those of expensive indium-tin-oxide.
Two different nanotechnology-based approaches to use graphene as the basis for purification and desalination of water look promising.
A novel method to control the configuration of atoms in semiconductors grown on graphene will make possible a vast array of new optical devices, including better solar cells.
By targeting the protein that attaches a type of immune cell called neutrophils to blood vessel walls where they cause serious tissues damage, the neutrophils are released and returned to the circulation to resume their normal functions.
RNA interference provides potential cures for various diseases by silencing the expression of specific genes in specific organs, but delivering the RNA molecules to the right place is very difficult. A novel nanoparticle provides unprecedented efficiency in silencing target genes in liver cells.
A possible top-down path to atomically precise manufacturing that passes through microscale machinery might be rendered easier because of recent progress in suppressing the Casimir force, which contributes to the ‘stiction’ problem often encountered with microelectromechanical systems.
The concern of the US GAO for a gap in nanomanufacturing is well-placed, but it is only half of the problem with the limited US vision of the impact of nanotechnology on the future world economy.
Pioneering a design and fabrication strategy to address individual nanoscale electronic devices to enable large-scale assembly into integrated computer circuits, a MITRE-Harvard team has assembled a functional nanoelectronic control computer.
A “sense of energy, momentum, and collegiality throughout the weekend” united attendees hearing about the integration of nano-engineered devices and materials into more complex systems, and the integration of nanoscale technologies into diverse applications.
A reconstituted high-density lipoprotein nanoparticle reduces inflammation in advanced atherosclerotic plaques in mice. Will it work in humans to prevent repeat heart attacks and stroke?
Design and prediction are integral to Atomically Precise Manufacturing and its development. This is in part because fully functional APM can be readily explored computationally today, to levels of precision that cannot be experimentally developed today. In such a context, design is not just a resource but an approach. With rapidly expanding computational power, examples [...]
