A team of engineers and scientists has shown for the first time that a hard-X-ray cavity can provide net X-ray gain, with ...

By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...

TPU researchers have developed a mathematical model that accurately describes how Cherenkov radiation propagates in an exotic ...

By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light and, as a result, its electronic and optical properties.

By changing the physical structure of gold at the nanoscale, researchers can drastically change how the material interacts with light – and, as a ...

To reproduce what Thomas Edison did, with the tools and knowledge we have now, is very exciting,” said co-author James Tour, ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

“It’s very slow, but over billions of years, it’s a very strong effect.” That is the main surprise of the observations of the ...

In a study published in Nano Letters, researchers at the US Argonne National Lab demonstrated a quadratic increase in ...

Modern biomedical research depends on the ability to see what is happening inside biological tissue. Among the available ...
