Minuscule Generators Convert Motion Into Nanoscale Electricity Source

Energy from tiny movements, ultrasound waves and even bloodflow can charge the devices

Is Graphene the New Silicon?

Graphene, a new material that combines aspects of semiconductors and metals, could be a leading candidate to replace silicon in applications ranging from high-speed computer chips to biochemical sensors.

World's Smallest Radio Fits in the Palm of the Hand ... of an Ant

Single carbon nanotube is fully functional radio, receiving music over standard radio bandwidth.

A New Wrinkle in Thin Film Science

A starburst of wrinkles form in a thin film material when a drop of water is placed on the film.

Building 3-D Neural Networks with Beads

Technique could yield insights into brain function, expedite drug development.

Cracking a Tough Nut for the Semiconductor Industry

Researchers at the National Institute of Standards and Technology have developed a method to measure the toughness — the resistance to fracture — of the thin insulating films that play a critical role in high-performance integrated circuits. The new technique could help improve the reliability and manufacturability of ICs and, better yet, it’s one that state-of-the-art microelectronics manufacturers can use with equipment they already own.

Strontium Atomic Clock ‘Best in Class’

The JILA strontium clock would neither gain nor lose a second in more than 200 million years, compared to NIST F-1’s current accuracy of over 80 million years.

Tweaking the Conductivity of Nanotube Composites

One of the immediate applications of carbon nanotubes (CNT) is as an additive to polymers to create electrically conducting plastics—a relatively low CNT concentration can dramatically change the polymer‘s electrical conductivity by orders of magnitude, from an insulator to a conductor.

Nanomaterials With a Bright Future

An innovative and inexpensive way of making nanomaterials on a large scale has resulted in novel forms of advanced materials that pave the way for exceptional and unexpected optical properties.

The Longest Carbon Nanotubes You've Ever Seen

Crafted with breakthrough manufacturing technique, centimeter-long fibers are visible to the naked eye.

NIST Imaging System Maps Nanomechanical Properties

The National Institute of Standards and Technology (NIST) has developed an imaging system that quickly maps the mechanical properties of materials—how stiff or stretchy they are, for example—at scales on the order of billionths of a meter.

NIST and Nanosoccer

Imagine a robotic David Beckham six times smaller than an amoeba playing with a “soccer ball” no wider than a human hair … with all of the action happening on a field the size of single grain of rice.
