Swedes claim leadership in composite nanowires

from the publication-priority dept.
A press release (26 February 2002) issued by researchers at the Lund Institute of Technology (LTH), Lund University in Sweden claims, ìEurope is one step ahead of the US in the development of a new type of semiconductor structure consisting of incredibly thin nano threads.ì The claim refers to recent announcements (see Nanodot posts on 1 February and 26 February 2002) of research to create cylinder-shaped nanoscopic nanowire bundles that interweave substances with different compositions and properties, so that well-defined junctions and interfaces with potentially important functionalities are incorporated within individual nanowires. The alternating bands of different semiconductor materials in the super-thin wires serve as electron and photon manipulators. According to the release, which seems largely to have been issued to establish publication priority, a Swedish team headed by Professor Lars Samuelson at the LTH, has taken the lead in this field of research. ìIn nano threads, we can combine semiconductor materials that no one has previously been able to grow. This results in entirely new electrical properties: a single electron can be monitored and made to run a unidimensional electronic steeplechase,î says Professor Samuelson.

Cryonics under fire in France

from the cold,-cold-world dept.
Anonymous Coward writes "The BBC is carrying a story about a couple in France whose frozen bodies may be thawed by local authorities. Cyronics have been outlawed there, and the official position is that burial or cremation are the only acceptable fates for the dead. The couple in question were apparently wealthy enough to have set up the necessary equipment on their own property, but even this does not guarantee their post-mortem privacy. While there are not too many details, it would appear that the husband placed his wife in a freezer in 1984 after she died of cancer, and he himself was placed in the freezer by his son when he recently died."

UK Govt. drafts laws that may censor nanotech research

Vik writes "According to this BBC article, the UK Government wishes to pass laws that allow it to veto research – even from the private sector – and to censor the publication of results.

While nanotechnology is not explicitly mentioned, it looks like the thin end of an anonymous wedge to curb research into any technology that the UK Government sees as being destabilising.

A list of "sensitive" technologoes is to be maintained, and students using them will have to be licenced by the government. Academics are livid. It is draconian stuff indeed, being one of those dreadful forms of legislation which prohibit a wide range of commonplace acts but are only enacted when the Government or police feel like it.

Vik :v)"

Several applications of the nanotubes mentioned in the article include composite, nanoelectronics, biomedical applications, energy storage, and thermal materials.

Dr. Richard Smalley of Rice University is also quoted in this article. There is also a brief report on Richard Smalley's team progress."

Corrected: Bush Administration proposes $679 million for NNI

from the you-wish dept.
The version of this item posted on 4 February 2002 incorrectly listed the amounts requested by federal agency in billions, rather than millions, of U.S. dollars. Unfortunately, the correct amounts are only millions. Below is the corrected version — Ed.

As part of the US$2.13 trillion budget proposed for the U.S. federal government for fiscal year 2003, the Bush Administration has requested a total of $679 million for the multi-agency National Nanotechnology Initiative (NNI), a 17 percent increase over FY2002.

The request includes:

According to the Analytical Perspectives: Budget of the United States Government, a document which discusses the Administrationís budge proposals in detail:

The budget provides $679 million for the multi-agency National Nanotechnology Initiative, a 17 percent increase over 2002. The initiative focuses on long-term research on the manipulation of matter down to the atomic and molecular levels, giving us unprecedented building blocks for new classes of devices as small as molecules and machines as small as human cells. This research could lead to continued improvement in electronics for information technology; higher-performance, lower-maintenance materials for defense, transportation, space, and environmental applications; and accelerated biotechnical applications in medicine, healthcare, and agriculture. In 2003, the initiative will focus on fundamental nanoscale research through investments in investigator-led activities, centers and networks of excellence, as well as the supporting infrastructure. Priority areas include: research to enable efficient nanoscale manufacturing; innovative nanotechnology solutions for detection of and protection from biological-chemical-radiological-explosive agents; the education and training of a new generation or workers for future industries; and partnerships and other policies to enhance industrial participation in the nanotechnology revolution. The convergence of nanotechnology with information technology, modern biology and social sciences will reinvigorate discoveries and innovation in many areas of the economy.

It is worth noting that the document also mentions the following areas that will be addressed by the U.S. Information Technology Initiative: ëëtrustíí (security, reliability, and privacy); high-assurance software and systems; and micro- and embedded sensor technologies.

Dekker wins Springer Award for molectronics work

According to an article in Die Welt ("Julius-Springer-Preis für die Erforschung von Nanoröhrchen", 4 February 2002, in German), Cees Dekker, a physicist in the Netherlands, has been awarded this yearís Julius Springer Prize in Applied Physics for his work on the electrical properties of carbon nanotubes and their application in molecular electronic circuits. Recent coverage of this work by Dekker and his colleagues ran here on Nanodot on 13 November, 8 August, and 5 July 2001

The award to Dekker marks the second time in recent years that the Springer Prize in Applied Physics has gone to researchers in molecular electronics. In June 2000, HP Labs researcher Stanley Williams and his UCLA collaborator Jim Heath received the award, one of the most prestigious international awards in the field, for their work in nanotechnology and molecular electronics.

EC-NSF Workshop will examine nanotech impacts

A major workshop to examine "Nanotechnology: Revolutionary Opportunities and Societal Implications" will be held on 31 January and 1 February 2002 in Lecce, Italy. The workshop is being jointly sponsored by the European Community and the U.S. National Science Foundation (NSF), and is the first event in a program of joint nanotechnology activities announced in December 2001.

The workshop will examine a broad array of potential socioecomomic impacts of nanotechnology. It follows and will build on the results of a similar workshop held in the U.S. in September 2000. A detailed description of the workshop program and schedule can be found on the NSF website.

Explosive silicon in MEMS?

Mr_Farlops writes "Serendipity struck for chemists at the University of California, San Diego, after a chip of porous silicon, laced with gadolinium nitrate, exploded after being scratched. An article in the EE Times describes the nature of this discovery and speculates about the possible uses of the substance in microscopic rockets and explosive charges. It also sets the mind daydreaming about tiny fuses made of nested nanotubes filled with fuel and oxidizers."
