President Proposes Funding for NIST FY 2006 Programs

An increased emphasis on research to support key Administration priorities in advanced manufacturing, homeland security, and health and information technologies highlights the FY 2006 request for the National Institute of Standards and Technology (NIST) submitted to the Congress on Feb. 7 by President Bush. The budget proposes a total of $532 million in NIST funding.

The NIST budget is divided into three appropriations:

  • $426.3 million for Scientific and Technical Research and Services (STRS)—an increase of 12.5 percent over 2005. It includes $420.6 million for the NIST laboratories, technical programs and major user facilities that provide U.S. industry and the science/technology community with the measurement capabilities, standards, evaluated reference data and test methods needed to support innovation and improve quality in virtually all technology-intensive sectors; and $5.7 million for the Baldrige National Quality Program.
  • $46.8 million for Industrial Technology Services (ITS), funding the Hollings Manufacturing Extension Partnership Program, helping small manufacturers across the nation to become more competitive and productive. Consistent with efforts to shift resources to best meet national needs, the FY 2006 budget proposes termination of the Advanced Technology Program.
  • $58.9 million for Construction of Research Facilities (CRF), covering critical safety, maintenance, repair and facilities upgrades.

The proposed budget request includes three STRS initiatives that target pressing national research priorities in Advanced Manufacturing ($19.6 million), Measurements and Standards for Homeland Security ($3 million), and New Measurement Horizons for the U.S. Economy and Science ($17.2 million).

The CRF budget request includes an increase of $32 million to address pressing issues of facility modernization primarily at the NIST's Boulder, Colo., laboratories and an increase of $3.4 million to support necessary preventive maintenance for NIST’s Advanced Measurement Laboratory, one of the world’s most sophisticated laboratories and a valuable national resource for critical measurements in nanotechnology, biotechnology, quantum computing and other exacting fields.

Sprinklers Shown Effective in Slowing Dorm Fires

Photo of a NIST experiment in a dorm day room without sprinklers 3 minutes and 47 seconds after a fire was ignited.

A n automatic sprinkler system significantly increases a person’s chances of surviving a dormitory fire, according to a report issued recently by the National Institute of Standards and Technology (NIST).

Three NIST experiments,* supported by a U.S. Fire Administration (USFA) initiative for fire safety in college housing, compared the hazards of fires in smoke detector-equipped dormitories with and without fire sprinklers in the room of fire origin. Researchers started fires in a day room or lounge area open to the corridor of a dormitory. They used the temperature of 120 degrees C (248 degrees F) as the cutoff mark for human survival. For comparison, the temperature of boiling water is 100 degrees C.

In two experiments without sprinklers, potentially fatal temperatures exceeding 120 degrees C as well as toxic gases reached a remote corridor 22.9 meters (75 feet) away within three minutes and completely spread throughout the corridor within another three minutes. In an experiment with sprinklers, temperatures at the 1.5 meter (five feet) level and below in the room where the fire began never exceeded 120 degrees C. No significant increase in heat was measured in the corridor during the experiment, allowing adequate time for residents to escape.

NIST conducted the experiments at a barracks donated by the Myrtle Beach Air Force Base Redevelopment Authority in Myrtle Beach, S.C. The USFA incorporated footage of NIST sprinkler tests into a fire safety video for college administrators and students.

*The NIST report Impact of Sprinklers on the Fire Hazard in Dormitories: Day Room Fire Experiments (NISTIR 7120) by D. Madrzykowski, D. Stroup and W.D. Walton is available, with video showing the experiments in progress in DVD format. Send requests to david.stroup@nist.gov.

Experiments Prove Existence of Atomic Chain 'Anchors'

The two images at left show the energy levels (vertical scale) and spatial positions (white lines) of electrons within a three-atom chain. The top image shows the calculated or theoretical results; the bottom image shows the measured energy levels in a physical experiment. Electrons are most likely to be located in the red areas and least likely in the blue areas. Both images indicate that the electrons in the outermost atoms (positioned on the far left and right at the bottom on the vertical scales) have lower energy than those within the center atom.

A toms at the ends of self-assembled atomic chains act like anchors with lower energy levels than the “links” in the chain, according to new measurements by physicists at the National Institute of Standards and Technology (NIST).

The first-ever proof of the formation of “end states” in atomic chains may help scientists design nanostructures, such as electrical wires made “from the atoms up,” with desired electrical properties.

The NIST experiments, described in the Feb. 4 issue of the journal Science,* involved measuring and comparing the electronic properties of gold atoms in short chains assembled on silicon surfaces. Energy levels of the electrons within the end atoms of the chains were lower than those of inner atoms. This condition arises because the structural, chemical and electronic symmetry of a chain is broken at each end, and the atoms’ electrons are redistributed to lower the chain’s energy. The electronic structure of atomic chains is comparable to the electronic structure of bulk crystals, in which surface atoms have different properties than atoms inside the crystal.

“In the past three decades the study of surface states on crystals has been a major endeavor by research groups from all over the world,” says Jason Crain, lead author of the Science paper. “Our study is the first to show the formation of localized states at the ends of single atom chains. The existence of end states will have implications for future studies of one-dimensional nanostructures.”

The NIST measurements were made with a scanning tunneling microscope (STM) and were enabled, in part, by the self-assembly of the gold chains on a silicon surface. Unlike the metal surfaces used in previous STM studies of single-atom chains, the silicon surface behaved as an insulator, allowing scientists to better isolate the chains and improve measurements of their atoms’ electron energy.

Devising Nano Vision for an Optical Microscope

A new optical imaging technology under development at NIST will use combinations of dynamically controlled light waves, optimized for particular properties (such as polarization). How this structured illumination field -- engineered specifically to highlight the particular geometry of each type of specimen -- scatters after striking the target may reveal features smaller than 10 nanometers.

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.

In a preliminary test of the embryonic technique, NIST scientists used violet light with a wavelength of 436 nanometers to image features as small as 40 nanometers, about five times smaller than possible with a conventional optical microscope.

Roughly speaking, such a feat is akin to picking up a solitary dime with a clumsy front-end loader. If successfully developed, the imaging technology could be readily incorporated into chip-making and other commercial-scale processes for making parts and products with nanometer-scale dimensions.

The wavelengths of light in the visible part of the spectrum greatly exceed nanoscale dimensions. Consequently, the resolution of conventional light-based imaging methods is limited to about 200 nanometers—too large to resolve the details of nanotechnology, which, by definition, are no more than half that size.

Resembling a 3-D checkerboard, this mirage-like pattern was formed by light waves after bouncing off a specimen with a peak-and-valley arrangement of etched lines. Such complicated wave patterns, the result of light scattering and interference effects, may be used to discern the dimensions of nanoscale features.

However, a newly begun, five-year research effort at NIST suggests that a novel combination of illumination, detection and computing technologies can circumvent this limitation. Success would extend the technology’s 400-year-long record as an indispensable imaging and measurement tool well into the expanding realm of nanotechnology.

Called phase-sensitive, scatter-field optical imaging, the computer-intensive technique under development at NIST uses a set of dynamically engineered light waves optimized for particular properties (such as angular orientation and polarization). How this structured illumination field—engineered differently to highlight the particular geometry of each type of specimen—scatters after striking the target can reveal the tiniest of details.

“The scattering patterns are extremely sensitive to small changes in the shape and size of the scattering feature,” explains Rick Silver, a physicist in NIST’s Precision Engineering Division.

Helping Future Engineers Use Today's Design Plans

Digital design software has virtually replaced blueprints across all manufacturing sectors. STEP (the Standard for the Exchange of Product Data), a universal format for product data that allows industrial partners with different proprietary software to understand and share engineering data, has accelerated this change. The National Institute of Standards and Technology (NIST) and PDES, Inc., an industry consortium, have just introduced a new STEP standard that should help ensure that tomorrow's engineers will be able to understand today's complex designs.

The new standard allows more sophisticated descriptions of proprietary designs and processes. This should eliminate the need for manufacturers to understand and consult a wide variety of original software programs. The additional descriptive information covering three-dimensional mechanical designs and assemblies also should help engineers to duplicate or repair complex machines such as aircraft, or ships, long after the original design and manufacturing software has been discontinued or changed beyond recognition.

The new STEP standard, called AP203 Edition 2, supports the latest advances in product design. It can be used to express complex three-dimensional mechanical part models and assemblies with features, tolerances, and colors, which may denote, for example, specific types of systems, such as hydraulic and electrical, or other details especially important in manufacturing.

The International Organization for Standardization (ISO) is expected to publish the new STEP protocol this month for distribution and implementation by software vendors and manufacturers. NIST developed AP203 Edition 2 with private-sector partners, including aerospace, automobile, shipbuilding and computer software corporations.

Cryptography Program Issues 500th Certificate

A program established in 1995 to help federal agencies protect sensitive information recently reached a milestone when the 500th cryptographic module was validated as conforming to a standard set of security requirements (Security Requirements for Cryptographic Modules, FIPS PUB 140-2). Cryptographic modules can be hardware and/or software that implement cryptographic logic or processes such as an encryption algorithm. NIST, in conjunction with the Canadian government’s Communications Security Establishment, developed the Cryptographic Module Validation Program to help federal agencies in both countries procure equipment known to conform to the federal security standard.

Federal agencies in the United States are required to use cryptographic modules that have been validated by this program. Nine laboratories in the United States, Canada and the United Kingdom are accredited by NIST to test cryptographic modules. The 500th certificate was issued in January to Research in Motion, Ontario, Canada.

For more information on the CMVP, including a list of validated modules and accredited testing laboratories, see http://csrc.nist.gov/cryptval.
