A strong laser beam can remove an electron from an atom – a process which takes place almost instantly. This phenomenon could now be studied with a time resolution of less than ten attoseconds (ten ...

Why does plastic turn brittle and paint fade when exposed to the sun for long periods? Scientists have long known that such ...

In a typical organic solar cell, an electron-donating material is interfaced with an electron acceptor. When the donor absorbs a photon, one of its electrons may jump across the interface, creating a ...

There are various ways to create artificial diamonds, but a new method developed by researchers including those at the University of Tokyo yields some extra benefits. By specially preparing samples ...

Nitrosamines are semi-volatile compounds that are an emerging class of drinking water contaminants. Due to their potency as carcinogens, nitrosamines are considered as priority pollutants. This app ...

Six critical steps are involved in the manufacturing of semiconductors. These steps include deposition, photoresist, lithography, etch, ionization and packaging. This article discusses several ...

Researchers have for the first time measured the first ionization energy of lawrencium, the last of the actinides, validating predictions of the element’s electronic structure (Nature 2015, DOI: ...
