The critical aspects of the corrosion of metal electrodes in cathodic reductions are covered.
We discuss the involved mechanisms including alloying with alkali metals, cathodic etching …

Over the past decade, topological materials—in which the topology of electron bands in the
bulk material leads to robust, unconventional surface states and electromagnetism—have …

Design principles and predictions of new three-dimensional (3D) Dirac semimetals are
presented and placed in the context of currently known materials. Three different design …

A generic definition of oxidation state (OS) is formulated:“The OS of a bonded atom equals
its charge after ionic approximation”. In the ionic approximation, the atom that contributes …

The oxidation state is the simplest attribute of an element in a compound. It is taught early in
the chemistry curriculum as a convenient electron-counting scheme for redox reactions. Its …

This chapter reviews possible experimental aspects of relativistic effects in heavier Main
Group elements and their compounds. Attention is focused on the sixth, seventh and eighth …

Experimental evidence proving the unique stabilization of the 6s orbital in platinum and gold
is presented. The conclusions are drawn from the chemical reactivities, of both elements, as …

The platinum group metals (PGMs) are widely employed as catalysts, especially for the
mitigation of automotive exhaust pollutants. The low natural abundance of PGMs and …

Cathodic corrosion of metals discovered more than 120 years ago remains a poorly
understood electrochemical process. It is believed that the corrosion intermediates formed …

We report a new family of ternary 111 hexagonal Ln AuSb (Ln= La–Nd, Sm) compounds
that, with a 19 valence electron count, has one extra electron compared to all other known …
