Robin's research in transition metal chemistry, mixed-valence chemistry, metal-metal bonding and spectroscopy is embodied in over 535 scientific publications and 36 books written or edited, and was ...

Researchers have come up with a way to turn silicon into a direct bandgap semiconductor, opening the door to the manufacture of ultrathin silicon solar cells.

The history of synthetic chemistry offers a possible roadmap for ... Kekulé used this 'theory of valence' to propose structures for many simple organic molecules in 1858, and in the 1860s ...

Chemistry: The octet rule is a principle that states atoms tend to bond in such a way that they each have eight electrons in their valence shell, achieving a stable electronic configuration. It might ...
