Results: Researchers at the University of Basel, Switzerland, have created a practical form of lubrication for nanoscale electromechanical systems (NEMS) that reduces friction between the devices' tiny moving parts 100-fold. The new method is needed because liquid lubricants do not work at the nanoscale, and other dry approaches to reducing friction have been too difficult to use in experimental nanomechanical devices.

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.
