If you’re running an experimental nuclear and particle astrophysics laboratory, you’ve got to build some pretty sensitive detectors.  Noise in the detectors can create spurious measurements that can make any meaningful measurement impossible.  To make the detector signal clean, the detector and its environment needs to be made clean—literally. Steps in the process include Read More

  Highly enriched uranium (HEU) is a component of nuclear bombs.  If you aren’t making nuclear weapons, you don’t need to be making HEU.  That’s why places like the Department of Energy’s Savannah River Facility have been shut down.  Well, it’s more accurate to say they are being shut down, because even though they haven’t Read More

You’ve probably seen “sticky traps,” those containers hung in fields or orchards to capture insects.  Have you ever wondered what happens to those containers?  Obviously, the traps are used to monitor the insects, and for some sampling, all you need to do is pull the bug out of the glue.  But some of the insects Read More

As we’ve noted before, there’s not a whole lot of action in an ultrasonic cleaner video. You put something in, turn the machine on, and it comes out clean. You can’t see cavitation cleaning. You can’t see the microscopic bubbles being formed. You can’t see the ultrasonic waves impinge on those bubbles. You can’t see Read More
