Standard Knowledge for Robots

by National Institute of Standards and Technology
What do you know? There is now a world standard for capturing and conveying the knowledge that robots possess—or, to get philosophical about it, an ontology for automatons.

Digital Crime-Fighters Face Technical Challenges with Cloud Computing

by National Institute of Standards and Technology
The National Institute of Standards and Technology (NIST) has issued for public review and comment a draft report summarizing 65 challenges that cloud computing poses to forensics investigators who uncover, gather, examine and interpret digital evidence to help solve crimes.

Snowballs to Soot: The Clumping Density of Many Things Seems to Be a Standard

by National Institute of Standards and Technology
Particles of soot floating through the air and comets hurtling through space have at least one thing in common: 0.36. That, reports a research group at the National Institute of Standards and Technology (NIST), is the measure of how dense they will get under normal conditions, and it’s a value that seems to be constant for similar aggregates across an impressively wide size range from nanometers to tens of meters.*

From Separation to Transformation: Metal-Organic Framework Shows New Talent

by National Institute of Standards and Technology
This gift from science just keeps on giving. Measurements taken at the National Institute of Standards and Technology (NIST) show why a material already known to be good at separating components of natural gas also can do something trickier: help convert one chemical to another, a process called catalysis. The discovery is a rare example of a laboratory-made material easily performing a task that biology usually requires a complex series of steps to accomplish.

Physicists Discover 'Quantum Droplet' in Semiconductor

by National Institute of Standards and Technology
JILA physicists used an ultrafast laser and help from German theorists to discover a new semiconductor quasiparticle—a handful of smaller particles that briefly condense into a liquid-like droplet.

Nearly Everyone Uses Piezoelectrics. Be Nice to Know How They Work.

by National Institute of Standards and Technology
Piezoelectrics—materials that can change mechanical stress to electricity and back again—are everywhere in modern life. Computer hard drives. Loud speakers. Medical ultrasound. Sonar. Though piezoelectrics are a widely used technology, there are major gaps in our understanding of how they work.
