The first endmember is neutral, corresponding to stoichiometric FeO, and the following two have the charge \(+1\) and \(-2\). The latter two can be combined to form the neutral compound Fe\(_{2/3}\)O, more conveniently written FeO\(_{1.5}\) or Fe\(_2\)O\(_3\) (not to ...
Melarsoprol (mel B; Arsobal) is an arsenical created by the efforts of Freidheim in the late 1940s. His initial compound, melarsen oxide, p-(4,6-diamino-s-triazinyl-2-yl) aminophenylarsenoxide, was complexed with dimercaptopropanol (British antilewisite) to form a less toxic complex,...
Every compound can be identified by a unique arrangement of the atoms in the crystal structure, which determines the inter–atomic distances and the compositional ratios and thus helps understanding specific material properties. For this reason, crystal structure determination and analysis are essential ...
The ionic radius may be larger or smaller than theatomic radius(radius of a neutral atom of an element), depending on the electric charge of the ion. Cations are typically smaller than neutral atoms because an electron is removed and the remainingelectronsare more tightly drawn in toward the ...

ionic gels solve the problem by combining polymer mechanical compatibility and swift switching response. An ionic gel is a semi-solid compound that retains charge owing to the insertion of an IL into the polymer during the drying stage. The colloidal particles in the mixture prevent it from curin...

An antistatic agent is a compound used for treatment of materials or their surfaces in order to reduce or eliminate buildup of static electricity. Its role is to make the surface or the material itself slightly conductive, either by being conductive itself, or by absorbing moisture from the ...
