Practically everything you use in your everyday life works because of measurement science. Without precise measurements, your car wouldn’t run, your phone wouldn’t work, hospitals couldn’t function, and the ATM would fail.
The National Institute of Standards and Technology (NIST)…
Imagine how a phone call works. Your voice is converted into electronic signals, shifted up to higher frequencies, transmitted over long distances, and then shifted back down so it can be heard clearly on the other end. The process enabling this shifting of signal frequencies is called frequency…
Wire bonding is a key process in semiconductor production. Extremely fine wires with diameters of 15 to 75 µm are used to create tiny electrical connections between a semiconductor chip and other components. The distances between the bond wires are often less than 100 µm. Any deviation, however…
In 1988, a small company began developing and supplying electronic instruments that automatically compensate for temperature-induced errors in industrial gages that are used to make precision dimensional measurements. Its products are now in use worldwide, improving factories and workshops that…
The world keeps time with the ticks of atomic clocks, but a new type of clock under development—a nuclear clock—could revolutionize how we measure time and probe fundamental physics.
An international research team led by scientists at the Joint Institute for Laboratory…
It’s not easy making green.
Scientists have made small red and blue lasers for years, but other colors have been a challenge. Now, researchers have filled an important technology gap by creating orange, yellow, and green lasers tiny enough to fit on a chip. Low-noise, compact…
