Image credit: Courtesy National Institute of Standards and Technology Quantum Daisy. Twelve cobalt atoms arranged in a circle on a surface of copper produce a daisy-like pattern from the interference of electron waves. This image was made with a one-of-a-kind instrument that, acting autonomously, picks up and places individual atoms anywhere on a surface. NIST scientists are studying the quantum properties of different atom arrangements to help improve the design and fabrication of nanoscale devices. Read more. |
Image credit: Courtesy National Institute of Standards and Technology Magnesium Oxide Dice. NIST scientists are developing new three-dimensional chemical imaging methods. Using a scanning transmission electron microscope, a tilting stage, and sensitive detectors, NIST researchers can construct images that reveal both the chemical components and the complex shapes of crystal structures. This image shows cubes of magnesium oxide. Nanoscale particles of gold were deposited on the crystal faces to help define the surface topography.

Image credit: Courtesy National Institute of Standards and Technology Silicon staircase. Steps of silicon serve as a natural ruler for measuring vertical dimensions. This silicon "target" has step heights ranging from tens to hundreds of nanometers leading down to a flat, single atomic layer measuring only 0.3 nanometer. The microscope used to make this image sits on an isolated concrete slab equipped with air springs to cancel out even minute vibrations that could ruin the nanoscale measurements. |

Strength of Thin Films. Colorized micrograph of a nanoporous insulation film after “wrinkling” with a new NIST measurement method. The method measures the strength and stiffness of a thin-film sample in about 2 seconds, as compared with several minutes for indentation and other conventional approaches. In addition, the NIST-developed technique accommodates high-throughput testing, so that hundreds or even a few thousand systematically varying samples can be tested in rapid succession. Read more. |

Sizing. A new NIST technique uses micrometer-sized channels
etched into a device to produce self-assembled nanocells called liposomes
of specific sizes from as large as about 240 nanometers (nm) to as small
as about 100 nm. The peaks on this three-dimensional plot indicate where
the highest concentration of liposomes are forming within the microchannel.
The method may have applications as an improved method for encapsulating
drug therapies. Read

Image credit: Courtesy National Institute of Standards and Technology Magnetic Monet. This graphic shows the magnetic "domains" within thin-film rings of a new advanced material for making non-volatile logic devices. Changes in color indicate changes in the direction of the magnetization of the material. Housed in an Advanced Measurement Laboratory metrology wing 12 meters (40 feet) underground, the NIST-developed instrument that recorded this data is the highest resolution magnetic imaging instrument in the United States.

New
Matter Form. False color images of a condensate formed from
pairs of fermion potassium atoms. Higher areas indicate a greater density
of atoms. Images from left to right correspond to the increasing strength
of attraction between the atoms that form fermion pairs as the magnetic
field strength is varied. Read

Optical Nanovision. 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.

Medical
Buckyballs. Computer model of a molecule made by LUNA Innovations
of Blacksburg, Va. The company plans to produce novel "buckyball"
materials for medical diagnostics and other military and commercial
applications. The technology was developed in part with a 2001 award
from NIST's Advanced Technology Program (ATP). The ATP grant helped
to accelerate the development process for new nanomaterials for medical
imaging and drug delivery. Read

Teleportation
Trap. NIST physicists have demonstrated “teleportation”
by transferring key properties of one atom to another atom without using
any physical link. Teleportation takes place inside an ion trap made
of gold electrodes deposited onto alumina. The trap area is the horizontal
opening near the center of the image. Read

Nanowires. NIST researchers have demonstrated a technique for growing well-formed, single-crystal nanowires in place on a commercially important substrate. The scanning electron microscope image above shows rows of horizontal zinc-oxide nanowires grown on a sapphire surface. The gold nanoparticles are visible on the ends of each row. The nanowires are only 3 nanometers (nm) in diameter. Read more.
