| Scientists entice superconducting devices to act like atoms |
24 February 2005 - National Institute of Standards and Technology (NIST)

| Devising nano vision for an optical microscope |
10 February 2005 - National Institute of Standards and Technology (NIST)
Contrary to conventional wisdom, technology's advance into the vanishingly small realm of molecules and atoms may not be out of sight for the venerable optical microscope, after all. In fact, research at the National Institute of Standards and Technology (NIST) suggests that a hybrid version of the optical microscope might be able to image and measure features smaller than 10 nanometers - a tiny fraction of the wavelength of visible light. |

| Software tool finds needles in data haystacks |
08 December 2004 - National Institute of Standards and Technology (NIST)
When looking for a needle in a haystack, it's helpful to know what a needle looks like. A new software tool developed by researchers at the National Institute of Standards and Technology (NIST) makes it possible to find chemical 'needles' in data 'haystacks' without having to know anything about the 'needle' in advance.

| New project takes measure of plastic electronics |
25 November 2004 - National Institute of Standards and Technology (NIST)
Before the emerging field of organic electronics can deliver on its commercial promise, however, new measurements, standards and processing capabilities must be developed. Creating many of the requisite tools is the aim of a new five-year research effort at the National Institute of Standards and Technology (NIST). |

| Lighting the way to better nanoscale films |
30 August 2004 - National Institute of Standards and Technology (NIST)
Most miniature electronic, optical and micromechanical devices are made from expensive semiconductor or ceramic materials. For some applications like diagnostic lab-on-a-chip devices, thin-film polymers may provide a cheaper alternative, but the structure and properties of these materials - often no more than a few nanometers (nm) thick - are difficult to determine. In addition, defects in the thin polymer masking materials used to 'print' integrated circuits can produce malfunctioning components. Consequently, researchers would like to have a non-invasive method for scanning polymer films for defects at high resolution. |

| New microfluidic device tackles tough synthesis tasks |
30 August 2004 - National Institute of Standards and Technology (NIST)
A new type of microfluidic device that can help industry to optimize paints, coatings for microelectronics and specialty polymers has been developed by National Institute of Standards and Technology (NIST) researchers. The device is made of a chemically durable plastic that is resistant to many common organic solvents. It was fabricated with a rapid prototyping method also developed at the agency. |

| Supercool! Model unscrambles complex crystallization puzzle |
30 August 2004 - National Institute of Standards and Technology (NIST)
To the wonderment - and the befuddlement - of scientists, the patterns that form as plastics, metals and many other materials crystallize can vary incredibly, ranging from sea-urchin-like spheres to elaborate tree-like branches. |

| Carbon nanotubes eliminate manufacturing woe |
13 August 2004 - National Institute of Standards and Technology (NIST)
Researchers at the National Institute of Standards and Technology (NIST) have discovered that the addition of carbon nanotubes to a common commercial polymer, polypropylene, leads to dramatic changes in how the molten polymer flows. This process eliminates a widespread manufacturing headache known as 'die-swell' in which polymers swell in undesirable directions when passing through the exit port of an extruder (a machine for producing more or less continuous lengths of plastic sections). |

| NIST lab experiments simulate house-to-house fire spread |
30 July 2004 - National Institute of Standards and Technology (NIST)
In a recent series of full-scale laboratory experiments at the National Institute of Standards and Technology (NIST), it took less than five minutes for flames from a simulated house with combustible exterior walls to ignite a similar 'house' six feet away. The experiments were conducted July 19, 2004, at the NIST Large Fire Facility. The tests, along with additional tests conducted on July 27, 2004, with more fire-resistant structures, are part of a program to develop computer models for predicting the spread of fire in residential communities. |

16 July 2004 - National Institute of Standards and Technology (NIST)
Researchers at the National Institute of Standards and Technology (NIST), along with their colleagues at several companies, are completing experiments that validate new standards aimed at improving emerging new microelectromechanical systems, or MEMS, devices. Microaccelerometers, the devices used to activate automotive airbags, are MEMS devices. In the future, microscopic MEMs devices made with gears and motors may, for example, be developed to clear blockages in arteries. |

| When microns matter - Web site smooths the way |
23 April 2004 - National Institute of Standards and Technology (NIST)
A new National Institute of Standards and Technology (NIST) Web site enables manufacturers to check the accuracy of measurement software used to verify the smoothness of product surfaces. Automotive, aerospace and optic industry engineers should find the NIST virtual surface calibration Web site particularly useful. Those industries rely on precise measurements of surface smoothness to ensure the efficiency of cylinder-piston engines, to make high-performance metal wind tunnels, and to produce better optical components. |

| Advice for designing reliable nanomaterials |
16 January 2004 - National Institute of Standards and Technology (NIST)
Stronger or tougher? For designers of advanced materials, this tradeoff may complicate efforts to devise efficient methods for assembling nanometer-scale building blocks into exotic ceramics, glasses and other types of customized materials. 'Not all properties may benefit from microstructural refinement, so due caution needs to be exercised in materials design,' writes the National Institute of Standards and Technology's (NIST) Brian Lawn in the January issue of Journal of Materials Research. |
