One hundred fifty years after Russian chemist Dmitri Mendeleev published his system for neatly arranging the elements, the periodic table it gave birth to hangs in every chemistry classroom in the ...

A new version of the periodic table of elements has predicted hundreds of highly charged ions that could be used to create the next generation of optical atomic clocks. The periodic table, first ...

How a quantum view of electron states enabled us to understand the stability of matter It’s generally agreed that this year has been designated the UN International Year of Quantum Science and ...

(1632-1723) and Englishman Robert Hooke (1635-1703). Both played instrumental roles in the identification of microorganisms using glass lenses and essentially launched the fields of optical microscopy ...

Electron affinity is a fundamental concept in chemistry, reflecting the energy change that occurs when an electron is added to an isolated atom in its gaseous state. This property helps us understand ...

This review focusses strictly on existing plasma density models, including ionospheric source models, empirical density models, physics-based and machine-learning density models. This review is framed ...

In this study we analyze the storm-time evolution of equatorial electron pitch angle distributions (PADs) in the outer radiation belt region using observations from the Magnetic Electron Ion ...

RUN your fingers over the white keys of a piano. The notes get higher and higher as your hand moves to the right. On the eighth key, something beautiful happens: a note hangs in the air that embodies ...
