Ionic-liquid-induced ferroelectric polarization in poly(vinylidene fluoride) thin films
TL;DR: In this paper, thin films of ferroelectric β-phase poly(vinylidene fluoride) (PVDF) were spin-coated from a solution that contained small amounts of the ionic liquid (IL) 1-ethyl-3-methylimidazolium nitrate.

Enhanced electret charge stability on polyethylene films treated with titanium-tetrachloride vapor
TL;DR: In this article, low-density polyethylene (LDPE) films have been treated with titanium-tetrachloride vapor by means of the molecular layerdeposition method.

Michael R. Wertheimer,Amélie St-Georges-Robillard,Sophie Lerouge,Fackson Mwale,Bentsian Elkin,Christian Oehr,Werner Wirges,Reimund Gerhard +7 more
TL;DR: The influence of surface properties on the observed behaviors of two particular cell lines, human U937 monocytes, and Chinese hamster ovary cells are discussed, with particular emphasis on possible electrostatic attractive forces due to positively charged R-NH3+ groups and negatively charged proteins and cells, respectively.
