Rice University scientists have created the first two-terminal memory chips that use only silicon, one of the most common substances on the planet, in a way that should be easily adaptable to nanoelectronic manufacturing techniques and promises to extend the limits of miniaturization subject to Moore's Law.  Last year, researchers in the lab of Rice Professor James Tour showed how electrical current could repeatedly break and reconnect 10-nanometer strips of graphite, a form…

With the advent of nanometer-sized machines, there is considerable demand for stable, precise tools to measure absolute distances and distance changes.

(Chemical & Engineering News) Credit: Angew. Chem. Int. Ed. Common foodstuffs arent typical synthesis starting materials. But theyre exactly what a team of researchers used to make novel compounds that are porous, crystalline, and edible. By starting with food-grade -cyclodextrin (CD), salt substitute (potassium chloride), and grain spirits (ethanol), researchers were able to synthesize new types of metal-organic framework (MOF) compounds. The advance could have pharmaceutical and food science applications. Reference MetalOrganic Frameworks from Edible…

In the Federal Register issue of 08/13/2010, the Environmental Protection Agency (EPA) released for public comment a proposed rule that would, if adopted, significantly change the TSCA Inventory Update Reporting (IUR). The first part of the notice, "Supplementary Information", explains the proposed changes to 40 CFR Parts 704, 710, and 711. The text of the proposed rule follows the Supplementary Information. In the Supplementary Information, EPA states that it is proposing modifications to the IUR  to meet four…

Hollow rods of titanium oxide with the solid manganese oxide core removed. (Credit: UConn.) According to a University of Connecticut press release, researchers believe they have developed a new material that could be used as a catalyst in alternative fuel development. Featured in the September issue of the nanotechnology journal, Small, University of Connecticut chemistry professor Steven Suib describes a method developed for the production of a nanosized crystalline material that can potentially be used…

Monday's federal register carried a notice from the Food & Drug Administration (FDA) announcing a public workshop on "Medical Devices & Nanotechnology: Manufacturing, Characterization, and Biocompatibility Considerations" to be held September 23 2010, from 8AM to 5PM at the Hilton Washington DC/North Gaithersburg, in Gathersburg, MD. Persons interested in participating in the workshop need to register by September 15, 2010. The notice provides a link and details on how to register. If anyone wishes to make an oral presentation…

One of the ways of ensuring a sustainable solar cell industry is to make cheap and stable cells, using abundant and environmentally friendly materials. However, until now, many such solar cells, particularly those made from copper and zinc oxides, have had their performance limited by the poor collection of photogenerated charges from these materials. A new study in Advanced Materials shows how the problems of high cost and long fabrication times associated with the deposition…

The oxide compound europium titanate is pretty boring on its own. But sliced nanometers thin and physically stretched on a specially designed template, it takes on properties that could revolutionize the electronics industry, according to Cornell-led research. Cornell researchers made a thin film of europium titanate ferromagnetic and ferroelectric by "stretching" it. They did it by depositing the material on an underlying substrate with a larger spacing between its atoms. Credit: Cornell University The research team,…

Layers of graphene that are only as thick as an atom could help make human DNA sequencing faster and cheaper. Harvard University and MIT researchers have shown that sheets of graphene could be a big i...
