Non-conductive ferromagnets based on core double-shell nanoparticles for radio-electric applications.

Two fabrication schemes of magnetic metal-polymer nanocomposites films are described. The nanocomposites are made of graphene-coated cobalt nanoparticles embedded in a polystyrene matrix. Scheme 1 uses non-covalent chemistry while scheme 2 involves covalent bonding with radicals.

Prevention of CS "tear gas" eye and skin effects and active decontamination with Diphoterine: preliminary studies in 5 French Gendarmes.

Ortho-chlorobenzylidene malononitrile (CS) "tear gas" is a lacrimating riot control agent causing eye irritation, excessive lacrimation, and blepharospasm. Diphoterine has been efficacious for decontamination of a wide variety of eye and skin chemical splashes and was tested in CS exposure. Five French Gendarmes either entered a standard training CS exposure chamber, developed eye or skin signs and symptoms, and were post-exposure decontaminated with Diphoterine or used Diphoterine as pre-CS exposure prophylaxis in the eyes and on the face before entering the chamber.
