3M has introduced a sampling program for its HFE (hydrofluoroether) fluids that's available to engineers across a broad range of industries. The program gives companies the opportunity to experiment with and explore new applications for 3M HFEs as an alternative to chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS) in manufacturing and industrial processes. Primarily known for their use in precision cleaning of high-value, complex parts used in the electronics, computer, aerospace, medical equipment, and automotive industries, 3M HFEs also serve as: a carrier for specialty lubricant deposition on computer hard-disk drives; a component in spray contact cleaners used in electrical maintenance and repairs; an extraction medium to isolate oils or fragrances; a formulating agent combined with more active chemicals to neutralize their flammability or aggressiveness; a fluid for recirculating heat transfer; and an alternative to organic solvents for cleaning metallic and non-metallic chamber surfaces in dry-etch semiconductor wafer equipment. "Currently, there is no other product available in the marketplace with the desirable balance of performance, workplace safety, and environmental properties of 3M HFEs," claims Kathryn Williams, marketing operations manager, 3M Specialty Fluids.

The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
