We are proud to announce our final conference program for Foresight@Google‘s 25th Anniversary Conference Celebration, held June 25-26 in Mountain View, CA. For $50 off registration use code: NANODOT This weekend – full of plenary talks, panels, and breakout sessions – is a unique opportunity to be stimulated, enlightened and inspired by direct interaction with [...]
A bacterial virus called M13 was genetically engineered to control the arrangement of carbon nanotubes, improving solar-cell efficiency by nearly one-third.
Smaller, faster, cooler: graphene transistors show promise for practical analog signal processors, for magnetic memory devices, and for self-cooling electronic circuits.
A shear flow processing method has been developed to control the surface attachment and orientation of DNA molecules to use for DNA-organic semiconductor molecular building blocks.
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.
Sputtering a pattern of zinc atoms on a graphene surface, followed by an acid rinse to remove the zinc, also removes exactly one atomic layer of graphene from where ever the graphene was covered with zinc atoms, forming a pattern on the graphene surface that is atomically precise in the vertical dimension. Resolution in the horizontal dimensions is determined by the mask used to sputter zinc.
New options to control nanoelectronic systems may arise from the demonstration that mechanical manipulation can control conductance through single molecule electrode junctions.
James C. Ellenbogen writes to provide insight and personal perspective on the world’s first programmable nanoprocessor, achieved as the product of a collaboration between Harvard and MITRE, with the team at MITRE comprising Shamik Das, James Klemic, and Ellenbogen.
Researchers at Harvard and MITRE have produced the world’s first programmable nanoprocessor
Sometimes the behavior of electrons in nanostructures can be modelled using classical laws of motion, while at other times more computationally challenging quantum methods are necessary to obtain useful results. Christopher W. Ince of the Nanotechnology Research Foundation writes with news of a new method to distinguish classical from quantum behavior in electrons: Researchers from [...]
The formation of a supramolecular bilayer is induced by buckyball guest molecules.
Singapore and European Union launch project to create and test a molecular-sized processor chip.
A review article presents the amazing features of graphene and discusses how it might complement or replace silicon for the fabrication of electronic devices.
Unique properties of two-dimensional arrays of carbon atoms promise both immediate applications and advantages for the development of advanced nanotechnology.
Nanotechnology Now brings news of a recent Atom Technology workshop in Singapore featuring dual Foresight Institute Feynman Prize winner Christian Joachim, Feynman Prize founder Jim Von Ehr of Zyvex Labs and Zyvex Asia, and Foresight Roadmap participant Damian Allis of Syracuse University: Atom Technology is IMRE’s flagship program led by well known scientist Prof. Christian [...]
Scientists Create World’s First Molecular Transistor. Very nice writeup of the research over at Next Big Future. To my mind what’s new here isn’t the transistor per se — semiconducting and conductive states have been known in CNTs for over a decade, and FET and diode-like arrangements of them have been around for the same. [...]
Technology Review: Complex Integrated Circuits Made of Carbon Nanotubes. The first three-dimensional carbon nanotube circuits, made by researchers at Stanford University, could be an important step in making nanotube computers that could be faster and use less power than today’s silicon chips. Such a computer is still at least 10 years off, but the Stanford [...]
Nanotechnology researchers find reliable, mess-free way to grow graphene. from nanowerk “You can imagine trying to peel a piece of shrink wrap off a dish to put it on a new dish — it’s going to be messy,” said lead researcher Jiwoong Park, Cornell assistant professor of chemistry and chemical biology. Inspired by previous [...]
Potential leap forward in electron microscopy. from Eurekalert. Why it matters: A non-invasive electron microscope could shed light on fundamental questions about life and matter, allowing researchers to observe molecules inside a living cell without disturbing them. If successful, such microscopes would surmount what Nobel laureate Dennis Gabor concluded in 1956 was the fundamental limitation [...]
