Precious Plastic is an open hardware plastic recycling project and is a type of open source digital commons project. The project was started in 2013 by Dave Hakkens and is now in its fourth iteration. It relies on a series of machines and tools which grind, melt, and inject recycled plastic, allowing for the creation of new products out of ...
The minimum bid was US$3 million and the sale closed January 16, 2003. [2] The city of Carlotta, California was up for auction on eBay in February 2003. [3] In September 2004, the Indiana Firebirds arena football team was auctioned off, first in a regular auction that failed to reach the reserve price, [4] and again as a "Buy it Now" item for ...
Insulating specimens charge up by the electron beam making imaging problematic or even impossible. (c) The gas itself is used as a detection medium producing novel imaging possibilities, as opposed to vacuum SEM detectors. (d) Plain plastic scintillating BSE detectors can operate uncoated without charging.
For detectors of such a size, gamma rays may Compton scatter out of the detector's volume before they deposit their entire energy. In this case, the energy reading by the data acquisition system will come up short: the detector records an energy which is only a fraction of the energy of the incident gamma ray.
The charged aerosol detector (CAD) is a detector used in conjunction with high-performance liquid chromatography (HPLC) and ultra high-performance liquid chromatography (UHPLC) to measure the amount of chemicals in a sample by creating charged aerosol particles which are detected using an electrometer.
Chip containing aluminium kinetic inductance detectors with tin absorbers. Image credit: Argonne National Lab. The kinetic inductance detector (KID) — also known as a microwave kinetic inductance detector (MKID) — is a type of superconducting photon detector capable of counting single photons whilst simultaneously measuring their energy and arrival time to high precision.

The tube, which can contain the fill gas boron trifluoride or helium-3, is surrounded by a plastic moderator that reduces neutron energies prior to capture. When a capture occurs in the fill gas, the energy released is registered in the detector. A modern one-piece Geiger–Müller counter, including Geiger–Müller tube type 70 019 (at the top)
