These quantum wiggles in electronic structure prevent strontium titanate from rearranging itself into ferroelectric order.
Researchers are using a technique they developed to observe minute distortions in the atomic structure of complex materials, shedding light on what causes these distortions and opening the door to ...
Strontium 90 is probably the most-feared fission product. Chemically similar to calcium, it is absorbed along with calcium by the human system and deposited in the bones, where its persistent ...
Scientists from the University of Colorado Boulder have created an atomic clock using lasers and strontium atoms that’s incredibly accurate—only losing one second every 40 billion years ...
The researchers found that the weaker chemical bonds that hold lanthanum and strontium in place in LSAT's atomic structure made them more susceptible to being pushed or pulled by small variations ...
In another advance at the far frontiers of timekeeping by National Institute of Standards and Technology researchers, the latest modification of a record-setting strontium atomic clock has ...
A super-accurate atomic clock just got more accurate. Thanks to new modifications, a record-setting strontium atomic clock is now so stable that it could theoretically "tick" for 15 billion years ...
Image of the trapped strontium atoms fluorescing under the blue light. Atoms are trapped within an ultra-high vacuum before being probed by the clock laser to determine the transition frequency.
The most precise timepiece ever created, a strontium atomic clock, won't lose or gain a second over the next 15 billion years.
Unfortunately, strontium atoms, of all things, react relatively strongly to changes in the ambient temperature; their atomic levels are then shifted energetically, which causes the clock to become ...
