Carbyne – a straight line of carbon atoms linked by double bonds or by alternating single and triple bonds — is the next stiff, carbon-based structure with unusual and desirable properties. It has been observed under limited natural and experimental conditions, is expected to be difficult to synthesize and store, and now has been theoretically [...]
Materials scientists have pursued the question of why vertically aligned carbon nanotube forests show much lower modulus values than expected. Now researchers from Georgia Tech have found that the nanotubes they fabricate contain kinks that dramatically diminish modulus value. In other words, the nanotubes are not straight; therefore, they are not stiff. The government-funded research [...]
In simplest terms, cellular automata can be thought of as groups of ‘cells’ in which the state of an individual cell will flip depending on the states of its neighbors. A ‘cell’ can be a pixel, a molecule, etc. The mathematical rules associated with cellular automation are complex and have been applied to fields as [...]
Good old fashioned boxes are here to stay, even in the context of nanoscale devices. Across a broad range of technologies and size regimes, boxes serve as containers for components, barriers against contaminants and/or radiation, and, as in the case of cell membranes, can be permeable to allow selected interactions between the interior and exterior. [...]
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 [...]
Soon after graphene sheets were being produced on a laboratory scale routinely, researchers began producing the hydrogenated version graphane (with a hydrogen atom on each carbon). This step is one of many approaches aimed at harnessing graphene’s powerful conductivity and is also being explored for hydrogen storage and other potential applications (more info in this [...]
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 [...]
On the list of potential post-silicon materials for electronics and chips is none other than silicon. More specifically, silicene — 2D sheets of hexagonally arranged silicon atoms, structurally analogous to graphene and experimentally characterized by physicist Guy Le Lay of Aix-Marseille University in France (2012 abstract here). While graphene possesses exceptional performance qualities, it can’t [...]
Researchers from UCLA’s California NanoSystems Institute and Northwestern University have combined multiple imaging techniques to produce high quality 3D images of platinum nanoparticles, allowing advanced visualization of atomic-scale structural defects (an important advancement over X-ray crystallography). The original 2012 work, published in Nature and posted by Jim Lewis here, used electron tomography to study 10-nm [...]
Scanning probe manipulation of individual atoms and small molecules were amongst the early laboratory successes that helped bring broad scale attention to the feasibility and potential of nanoscale technologies, especially molecular fabrication. Basic manipulations of atoms and bonds by scanning probe have become familiar capabilities that follow similar protocols: the STM tip is precisely positioned [...]
A National Academy of Sciences panel has recommended a four-part research effort focused on preventing and managing any potential health and environmental risks of nanomaterials.
A green nanotechnology roadmap released by the American Chemical Society describes the opportunities and barriers to developing commercial applications of nanomaterials that present little threat of harm to health and the environment, and concludes with an action agenda to more forward.
A new book collects the papers and discussions from the 2007 Solvay Conference “From Noncovalent Assemblies to Molecular Machines”.
Robert A. Freitas Jr. has made available his chapter on nanorobotics from the book The Future of Aging.
US National Nanotechnology Initiative wants your comments on its strategic plan.
A book on nanotechnology education and workforce training written by Judith Light Feather and Miguel Aznar
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 [...]
Foresight ally Jeff Ubois has a new book out, published by Fondazione Giannino Bassetti, Conversations on Innovation, Power, and Responsibility. Yours truly is quoted. An excerpt: Peterson suggests that a closer look at the software developers might provide some clues about responsible cultures of innovation. “If you really want to know how to create a sense of responsibility, [...]
The Royal society has a new website making freely available a selection of classic papers from the history of science. (h/t Luboš Motl’s The Reference Frame): I am just looking at an Isaac Newton’s letter about light and colors sent to the editor of Cambridge University Press in February 1671/72. It describes some Newton’s basic [...]
