Results: Researchers at Swinburne University of Technology in Australia have developed a light-responsive material that can store data at a density of over 1,000 gigabytes per cubic centimeter. It is made up of 10 layers of gold nanoparticles that change shape depending on the color and polarization of light shined on them, a property that makes it possible to store more than one bit of information in a given region of the material.

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.
