Gold nanospheres show a path to all-optical computing.
Vast amounts of data zip across the Internet each day in the form of light waves conveyed by optical fibers. But our computers still rely on electrical signals traveling through metal wires, which have much lower bandwidth.
Optical interconnects that could guide light through the labyrinth of a circuit board would increase computing speed and save power, but so far they haven't made it out of the lab.

Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation.
This document is part of the “How-To Guide for Most Common Measurements” centralized resource portal. This tutorial provides a detailed guide for measurement and device considerations to take temperature measurements using thermocouples. Get an introduction to thermocouples, which are inexpensive sensing devices widely used with PC-based data acquisition systems. Also review some specific thermocouple examples and learn how thermocouples work and ways to integrate them into a data acquisition measurement system.
