Faster analysis of materials

In work that could radically change how engineers search for new materials, MIT researchers have developed a way to test the mechanical properties of almost 600 different materials in a matter of days – a task that would have taken weeks using conventional techniques. The approach of combinatorial arrays and miniturization of analysis and testing …

Biotechnology’s Newest Chemical Tool

Exploiting biology’s own chemical toolbox, researchers have developed a new technique that will allow them to modify specific sequences within a DNA molecule. The approach will not only help reveal the impact of biochemical alterations to DNA, but could have far-reaching implications for DNA-based medical diagnosis and nanobiotechnology. Combining chemistry with biotechnology, Saulius Klimasauskas, a …

Yale Engineers Make Standardized Bulk Synthesis Of Nanowires Possible

Development of reliable nanowire fabrication will allow the exploration of the next steps in semiconductor miniaturization. This reported technology produces ten-times the number of NWs as previous technology and sets parameters for standardization of NWs. “This brings nanowires to an interface with the rest of the world of semiconductor research,” said Stern. “Until this point, …

Nanomedicine: Using nanotech to gain understanding and possibly controlling T-cells

In a new experiment, published last week in Science, Jay Groves and colleagues at the University of California at Berkeley designed an artificial membrane that allows them to begin to answer how receptors on t-cells effect and control immune system response. The membrane has proteins that are constricted in a specific region. When receptors on …

Other tech: Holographic-memory discs may put DVDs to shame

The discs, developed by InPhase Technologies, based in Colorado, US, hold 300 gigabytes of data and can be used to read and write data 10 times faster than a normal DVD. The company, along with Japanese partner Hitachi Maxell announced earlier in November that they would start selling the discs and compatible drives from the …

Possible Path to 100+ Qubit Quantum computers

It seems that bubbles of electrons lined up in ultracold liquid helium could be used to build a quantum computer capable of carrying out a staggering 10 to the 30th power simultaneous calculations. To make an electron bubble, start with liquid helium that has been cooled below 2.17 kelvin so that it behaves like a …

New Tool: Inside a quantum dot: Tracking electrons at trillionths of a second

New Research Enabling Tool: Researchers at the EPFL (Ecole Polytechnique Federale de Lausanne) have developed a new machine that can reveal how electrons behave inside a single nano-object. The results from initial tests on pyramidal gallium-arsenide quantum dots are presented in an article in the November 24 issue of Nature. The machine developed by Professor …

The Impossible Is Possible: Laser Light from Silicon

Now a trio of Brown University researchers, led by engineering and physics professor Jimmy Xu, has made the impossible possible. The team has created the first directly pumped silicon laser. They did it by changing the atomic structure of silicon itself. This was accomplished by drilling billions of holes in a small bit of silicon …

Discussion of ranking countries in nanotechnology

A Lux Research article divides nations are into four categories. The details are discussed at soft machines. Dominant (USA, Japan, Germany and South Korea) – strong both in basic research and commercialisation, Ivory Tower (UK and France), strong in basic research but weaker in commercialisation, Niche Players (Israel, Singapore and Taiwan), weaker in basic research …

Advancement in the creation of nanostructures using Scanning tunneling Microscopes

Francesca Moresco and colleagues at Freie University in Berlin said the interaction between the tip of a STM and atoms or molecules bound to a surface can be used to construct impressive nanostructures, such as the quantum corral. The researchers said they combined STM manipulation techniques with the ability of a molecule to assemble nanostructures …
