Structure and Thermal Stability of Co- and Fe - Intercalated Double Silicene Layers

The arrangement of Fe and Co atoms between two silicene planes was theoretically investigated. The research has shown that below 500 K Co atoms form stable lattices-"hexagonal" (with the lattice parameters 0.635 nm of AB configuration) and cubic (with the lattice parameter of 0.244 nm), whereas Fe atoms form cubic lattices only (with the lattice parameter of 0.281 nm). The system intercalated w...

Magnetically responsive biopolymeric multilayer films for local hyperthermia

We present a proof of concept on the use of thermomagnetic polymer films (TMFs) as heating devices for magnetic hyperthermia in vitro. The TMFs were prepared through spray assisted layer-bylayer assembly of polysaccharides and magnetic iron oxide nanoparticles, yielding an alternate magnetic-polymer multilayer structure. By applying a remote alternating magnetic field (AMF) (f = 180 kHz; H = 35...

Silicene: Recent theoretical advances

Core concept: silicene.

In 2003, physicists from the University of Manchester isolated flakes of graphene, a single layer of carbon atoms arranged in a honeycomb. The researchers described their methods in 2004 (1), and in 2010 they were awarded the Nobel Prize in Physics for discovering the wonder substance. Since then, researchers have shown that the 2D carbon material conducts electricity and is stronger than steel...
