NIST Team paves the way for hybrid devices of standard CMOS and molecular electronics from organic molecules

Side and top views of the NIST molecular resistor. Above are schematics showing a cross-section of the full device and a close-up view of the molecular monolayer attached to the CMOS-compatible silicon substrate. Below is a photomicrograph looking down on an assembled resistor indicating the location of the well. NIST team demonstrates that a single …

Variable sized quantum dots could lead to more efficient and partially transparent solar cells

Electron transport through a structure of nanoparticles (left) and more ordered nanotubes (center) is shown. At right, different wavelengths of light can be absorbed by different-sized quantum dots layered in a “rainbow” solar cell. Image credit: Kongkanand, et al. ©2008 ACS. Solar cells made of different-sized quantum dots, each tuned to a specific wavelength of …

Quantum computers could make very powerful pattern recognizers

Here is a research paper that discusses using adiabatic quantum computation using liquid state nuclear magnetic resonance quantum computers for pattern recognition. UPDATE:Pattern recognition is a critical aspect of artificial intelligence. I have a new article “Artificial Intelligence: You are soaking in it”, which discusses mostly ignored penetration of artificial intellience and its future with …

Any protein can be made from synthesized DNA on a chip

Harvard has a new protein array lab on a chip. The system could produce any desired protein from synthesized DNA placed on the chip. It is another step in making protein production and engineering and biotechnology in general faster and cheaper. Schematic representation of screening protein-protein interactions with NAPPA. (A) On each spot, a target …

Carbon Nanopipettes for cellular nanosurgery

University of Pennsylvania engineers and physicians have developed a carbon nanopipette thousands of times thinner than a human hair that measures electric current and delivers fluids into cells. Researchers developed this tiny carbon-based tool to probe cells with minimal intrusion and inject fluids without damaging or inhibiting cell growth. Drexel University College of Engineering had …

Graphite transistors could be the replacement for silicon

Graphene is one hundred times thinner than the smallest silicon transistor possible and graphene conducts electricity much more efficiently. However, graphene sheets tend to curl up and react with substances around them, making them difficult to build into devices. Graphite could provide the most of the electrical property benefits of graphene but be easier to …

China’s yuan closes 2007 at 7.30

The chinese currency advanced twice as fast as in 2006 as policy makers sought to curb inflation and cut a record trade surplus that has strained ties with the U.S. and Europe. `The government will choose to use appreciation of the yuan to solve the inflation problem,’ said Shen Minggao, Citigroup’s Beijing-based economist. `The appreciation …
