Syrup makers go high tech with wireless monitoring

For years, vacuum tubing technology has allowed maple syrup producers to draw more sap from trees, but such systems are prone to leaks caused by falling branches or hungry critters chewing on lines.

New vacuum power amplifier demonstrated at 0.85 Terahertz

The submillimeter wave, or terahertz, part of the electromagnetic spectrum falls between the frequencies of 0.3 and 3 terahertz, between microwaves and infrared light. Historically, device physics has prevented traditional ...

Mighty micropumps: Small but powerful vacuum pumps demonstrated

DARPA-funded researchers recently demonstrated the world's smallest vacuum pumps. This breakthrough technology may create new national security applications for electronics and sensors that require a vacuum: highly sensitive ...
