Engineers point way to better use of nanotubes as measuring tips
Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called "multi-walled carbon nanotubes" to more precisely measure structures and devices for electronics and other applications. view more (2005-10-13)
New NIST nano-ruler sets some very small marks
The National Institute of Standards and Technology (NIST) has issued a new ruler, and even for an organization that routinely deals in superlatives, it sets some records. view more (2009-09-23)
Getting to the core of the problem - CMD19CMMP with
Using the equations of quantum mechanics, which normally govern the bizarre physics that occurs at tiny atomic scales, has enabled geophysicists to answer a much larger-scale question - what the Earth`s core is made from. At the Condensed Matter physics conference on Tuesday 9 April, part of the Institute of Physics Congress in Brighton, Prof Mike... view more... (2002-03-26)
Supernovae-Cosmic Lighthouses
Supernovae stand out in the sky like cosmic lighthouses. Scientists at the Max Planck Institute for Astrophysics and at the National Astronomical Institute of Italy have now found a way to use these cosmic beacons to measure distances in space more accurately. view more (2007-02-12)
The longest carbon nanotubes you've ever seen
Using techniques that could revolutionize manufacturing for certain materials, researchers have grown carbon nanotubes that are the longest in the world. While still slightly less than 2 centimeters long, each nanotube is 900,000 times longer than its diameter. view more (2007-05-11)
Growing glowing nanowires to light up the nanoworld
The nano world is getting brighter. Nanowires made of semiconductor materials are being used to make prototype lasers and light-emitting diodes with emission apertures roughly 100 nm in diameter-about 50 times narrower than conventional counterparts. view more (2006-05-26)
Slicing solar power costs
University of Utah engineers devised a new way to slice thin wafers of the chemical element germanium for use in the most efficient type of solar power cells. They say the new method should lower the cost of such cells by reducing the waste and breakage of the brittle semiconductor. view more (2008-09-15)
Researchers bend light through waveguides in colloidal crystals
Researchers at the University of Illinois are the first to achieve optical waveguiding of near-infrared light through features embedded in self-assembled, three-dimensional photonic crystals. view more (2008-01-08)
Atomic force microscopy reveals liquids adjust viscosity when confined, shaken
Getting ketchup out of the bottle isn't always easy. However, shaking the bottle before trying to pour allows the thick, gooey ketchup to flow more freely because it becomes more fluid when agitated. The opposite is not typically true - a liquid such as water does not become a gel when shaken. view more (2008-04-30)
Tiny spectrometer offers precision laser calibration

Study: Nanotech processing 'greener' than oil refining
Using a method for assessing the premiums that companies pay for insurance, a team of scientists and insurance experts have concluded that the manufacturing processes for five, near-market nanomaterials - including quantum dots, carbon nanotubes and buckyballs - present fewer risks to the environment than some common industrial processes like oil... view more...

New 'superlens' reveals hidden nanostructures
A microscope used to scan nanostructures can be dramatically enhanced by using a 'superlens,' reports an international team of scientists from the Max Planck Institute (MPI) for Biochemistry and The University of Texas at Austin in this week's issue of Science. view more (2006-09-15)
Reach out and touch an oscillator: Cornell researchers find a new way to read nanoscale vibrations
Nanomechanical oscillators — tiny strips of vibrating silicon only a few hundred atoms thick — are the subject of extensive study by nanotechnology researchers. They could someday replace bulky quartz crystals in electronic circuits or be used to detect and identify bacteria and viruses. view more (2007-03-27)
Moving a bit nearer to a quantum computer
By the time you`ve had your new computer for six months, much faster processors will already be on the market. But there is a limit to how fast conventional computers can become. This is because computers process information in a step-by-step fashion, carrying out each part of the process in turn. To make things work really fast, we need to build... view more... (2002-07-23)
Fishing biomolecules
Rapid substance identification is an indispensable tool for laboratories and process monitoring. An optical biochip developed as part of the EU-funded project BIOMIC is capable of simultaneously measuring the concentrations of eight different proteins or DNA fragments. view more (2004-03-18)
Organic solar power
Solar cells made from conventional semiconductor materials such as silicon are becoming increasingly common. By contrast, cells which use organic dyes or electrically conductive plastics are relatively unknown. At the Hanover Fair: prototypes of such cells and possible applications. ----------- If solar power is to be generated in the future on a... view more... (2002-04-16)
