Ion

History of discovery The word ion comes from the Greek word ἰόν, ion, going, the present participle of ἰέναι, ienai, to go.This term was introduced (after a suggestion by the English polymath William Whewell) [3] by English physicist and chemist Michael Faraday in 1834 for the then-unknown species that goes from one electrode to the other through an aqueous medium.

Controlled polymerization of organic semiconductor

Emerging methods for the fabrication of multifunctional nanostructures from soft matter have allowed for the synthesis of complex macromolecules with varied morphologies and physical properties. Using organic semiconductors as building blocks, nanostructures with novel emissive properties and interesting charge-transport behaviour are increasingly accessible. Self-assembly processes have been

Polymer Properties Database

The degree of hydroxylation also affects the maximal moisture uptake which acts as a plasticizer and thus affects the mechanical and physical properties of the polymer. With increasing water uptake, the tensile strength, modulus of elasticity, and hardness are reduced, while impact resistance and elongation at break are greatly increased.
