Results: Researchers at MIT and the Air Force Research Laboratory at Edwards Air Force Base in California have made novel materials that cause oil to bead up and form near-spherical droplets that easily roll or even bounce off surfaces. The researchers also analyzed the mechanisms behind the materials' oil-repellent properties and developed design rules that could be useful for making similar materials in the future.

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.
