Multitasking nanotechnology Nanotechnology / Materials July 10, 2008 \| User rating: 4.8 / 5 after 8 vote(s) \| No comments yet Confocal microscope image of a self-assembled monolayer of a polychlorotriphenyl methyl radical patterned on a quartz surface. This multifunctional molecule behaves as an electroactive switch with optical and magnetic response.

Swerve left to avoid that satellite Nanotechnology / Materials July 09, 2008 \| User rating: not shown ( 4 vote(s) ) \| No comments yet Think you have trouble getting rid of the clutter in your living room? After more than 50 years of launching rockets and satellites into space, the human race now has to deal with the clutter left behind -- or is it "above"? ...

Improving Quantum Dot Synthesis Nanotechnology / Materials July 09, 2008 \| User rating: not shown ( 4 vote(s) ) \| No comments yet Materials researchers at the National Institute of Standards and Technology have developed a simplified, low-cost process for producing high-quality, water-soluble quantum dots for biomedical applications. By using a laboratory ...

Research helps understand factors that influence efficiency of organic-based devices Nanotechnology / Materials July 08, 2008 \| User rating: 4 / 5 after 6 vote(s) \| No comments yet Organic-based devices, such as organic light-emitting diodes, require a transparent conductive layer with a high work function, meaning it promotes injection of electron holes into an organic layer to produce ...

A better image for plastic solar cells Nanotechnology / Materials July 07, 2008 \| User rating: 4 / 5 after 15 vote(s) \| No comments yet A new way to help technologists develop efficient and inexpensive plastic electronic devices, such as plastic solar cells and a new type of transistor was showcased by physicist Andrea Liscio, who is supported ...
