The periodic table has been a vital foundational tool for material research since it was first created 150 years ago. Now, researchers add an entirely new dimension to the table, offering a new set of ...

A Skoltech professor and his Chinese colleagues have revised a key chemical concept, electronegativity, and determined this characteristic for all elements under varying pressures. The revamped notion ...

Electronegativity, an essential characteristic of all elements in the periodic table, measures an atom's ability to attract electrons towards itself within a chemical bond. This vital theoretical ...

Material properties change at high pressure. Scientists can generate pressures millions of times above ambient pressure and, in doing so, have found near-room-temperature superconductors, polymeric ...

Researchers synthesized a fluorinated electron-acceptor for use in organic semiconductors. The high electronegativity of the fluorine substituents enhanced the electron-accepting properties of the ...
