    Credit: NNI at nano.gov 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 hearing, held this past May, included Timothy Persons of US GAO, who spoke at Foresight’s 2014 Integration Conference (and whose work indicating shortfalls in US manufacturing and policy is highlighted…
  • The atomically precise manufacture of quantum dots

    Jim Lewis
    5 Jul 2014 | 8:14 pm
    This image shows a quantum dot molecule consisting of three 6-atom indium chains. (Image: Stefan Fölsch/PDI) One of the iconic milestones in the history of nanotechnology was the 1989 feat by Eigler and Schweizer at IBM (published the following April in Nature) of using an STM to arrange 35 xenon atoms on a nickel surface to spell IBM. The demonstration was done at 4 K and the atoms of the nickel crystal acted like an “egg carton” to hold the xenon atoms in place. For these and other reasons, although the symbolic impact of the accomplishment was enormous, it was not obvious…

  • Researchers discover boron 'buckyball'

    24 Jul 2014 | 12:00 am
    The discovery of buckyballs -- soccer-ball-shaped molecules of carbon -- helped usher in the nanotechnology era. Now, researchers from Brown University and universities in China have shown that boron, carbon's neighbor on the periodic table, can form a cage-like molecule similar to the buckyball. Until now, such a boron structure had only been a theoretical speculation. The researchers dubbed their new-found nanostructure 'borospherene.'

    Metal-based nanoparticles (NPs) are used in ever more products, which in their end-of-life phase are likely to end up in the aquatic environment. The potential for adverse biological effects is thus increasing and the need for risk assessment hence urgent. Current environmental risk assessment is inadequate for NPs, which owing to their small size have unique characteristics such as a relatively large surface area and high reactivity and hence behave differently from dissolved metals and from sub-micron-sized particles. This project will yield 1) a model for NP toxicity respecting the…

    Using a unique scanning tunneling microscope, dedicated to live imaging under high and varying-temperature conditions, you will follow on the atomic scale the processes that govern the nucleation and growth of monolayer materials, such as graphene and hexagonal boron nitride. These materials find potential application in future EUV lithography instrumentation. For these applications, the graphene (or h-BN) should be close to ideal, i.e. large areas with no holes, with a precisely defined number of layers (everywhere!), and with high mechanical strength. Such material cannot be produced at…

    By Sarah VogelSarah Vogel, Ph.D. is Director of EDF's Health Program. The hotly debated chemical BPA is back in the policy spotlight. This week Senator Edward Markey (D-Mass) joined Representatives Lois Capps (D-CA) and Grace Meng (D-NY) to announce the Ban Poisonous Additives (BPA) Act.  The bill would ban the use of BPA or bisphenol A from food packaging and mandates extensive consideration of the hazardous properties of any BPA alternative, so as to avoid substituting chemicals that may pose just as many health risks (as increasingly it appears to be with the case of the common BPA…

    By Richard DenisonRichard Denison, Ph.D. is a Lead Senior Scientist.  Jennifer McPartland, Ph.D. is a Health Scientist. EPA achieved a rather significant milestone today in releasing a final risk assessment for the solvent trichloroethylene (TCE).  This document is for the first of a group of 83 “work plan chemicals” EPA identified in 2012 as needing risk assessments and, where warranted, risk management. Why do we call it a milestone?  It is the first final risk assessment issued by EPA using its authority under the Toxic Substances Control Act (TSCA) in – wait for it – 28 years.

  • Rebuilding the UK’s innovation economy

    Richard Jones
    18 Jul 2014 | 12:22 am
    The UK’s innovation system is currently under-performing; the amount of resource devoted to private sector R&D has been too low compared to competitors for many years, and the situation shows no sign of improving. My last post discussed the changes in the UK economy that have led us to this situation, which contributes to the deep-seated problems of the UK economy of very poor productivity performance and persistent current account deficits. What can we do to improve things? Here I suggest three steps. 1. Stop making things worse. Firstly, we should recognise the damage that has been…
  • Business R&D is the weak link in the UK’s innovation system

    Richard Jones
    24 Jun 2014 | 5:23 am
    What’s wrong with the UK’s innovation system is not that we don’t have a strong science base, or even that there isn’t the will to connect the science base to the companies and entrepreneurs who might want to use its outputs. The problem is that our economy isn’t assigning enough resource to pulling through the fruits of the science base into technological innovations, the innovation that will create new products and services, bring economic growth, and help solve some of the biggest social problems we face. The primary symptom of the problem is the UK’s very poor…
  • Surely there’s more to science than money?

    Richard Jones
    15 Jun 2014 | 12:37 pm
    How can we justify spending taxpayers’ money on science when there is so much pressure to cut public spending, and so many other popular things to spend the money on, like the National Health Service? People close to the policy-making process tend to stress that if you want to persuade HM Treasury of the need to fund science, there’s only one argument they will listen to – that science spending will lead to more economic growth. Yet the economic instrumentalism of this argument grates for many people. Surely it must be possible to justify the elevated pursuit of knowledge in less…
  • Spin-outs and venture capital won’t fill the pharma R&D gap

    Now that Pfizer has, for the moment, been rebuffed in its attempt to take over AstraZeneca, it’s worth reflecting on the broader issues this story raised about the pharmaceutical industry in particular and technological innovation more generally. The political attention focused on the question of industrial R&D capacity was very welcome; this was the subject of my last post – Why R&D matters. Less has been said about the broader problems of innovation in the pharmaceutical industry, which I discussed in an earlier post – Decelerating change in the pharmaceutical…
  • Why R&D matters

    Richard Jones
    9 May 2014 | 9:27 am
    The takeover bid for the UK/Swedish pharmaceutical company AstraZeneca by US giant Pfizer has given rare political prominence to the issue of UK-based research and development capacity. Underlying much opposition to the deal is the fear that the combined entity will seek to cut costs, and that R&D expenditure will be first in the firing line. This fear is entirely well-founded; since Pfizer took over Wyeth in 2009 it has reduced total R&D spend from $11bn to $6.7bn, and in the UK Pfizer’s cost-cutting reputation was sealed by the closure of its Sandwich R&D facility in…

These air waveguides could have many applications, including long-range laser communications, detecting pollution in the atmosphere, making high-resolution topographic maps and laser weapons.Because light loses intensity with distance, the range over which such tasks can be done is limited. Even lasers, which produce highly directed beams, lose focus due to their natural spreading, or worse, due to interactions with gases in the air. Fiber-optic cables can trap light beams and…
  • Elon Musk says 500 mile range electric car will soon be possible

    Elon Musk explains why the Tesla Model S has twice the range of the Nissan Leaf and why Tesla will soon have electric cars with 500 mile range Tesla Electric cars have the highest energy density battery in the world, twice that of the Nissan Leaf. But their range is more than twice that of the Leaf so we come into other factors: what’s the drag co-efficient of the car, how much does it weigh, what’s the efficiency of the motor and gearbox, what’s the rolling resistance? All those factors affect the range.Recently Telsa Model S was assessed against a whole bunch of other cars for drag…
  • Carbon Nanotubes May Protect Electrodes for commercial version of Focus Fusion and machining has delayed the Tungsten electrode to September, 2014

    23 Jul 2014 | 5:02 pm
    While LPPFusion’s research team expects to eliminate the major sources of electrode erosion, enough to get rid of significant impurities in the plasma, some erosion will still exist. It won’t be enough to bother us during the current experimental phase, but once they are engineering a generator that fires 200 times second, remaining erosion will limit the lifetime of the electrodes. But there may be a way to protect the electrodes better—with a coating of carbon nanotubes.Neil Farbstein of Vulvox Nanobiotechnology Corporation suggested to LPPFusion joint development of a coating of CNT…
