Ni nanocrystals (NCs) were embedded in BaTiO3 epitaxial films using the laser molecular beam epitaxy. The processes involving the self-organization of Ni NCs and the epitaxial growth of BaTiO3 were discussed. With the in situ monitoring of reflection high-energy electron diffraction, the nanocomposite films were engineered controllably by the fine alternation of the self-organization of Ni NCs ...

Introduction Past experiments have already proven that silk, a natural protein produced by silkworms and spiders, exhibit intriguing physical properties such as exceptionally high moduli and toughness. Silk fibroins (SF) can be further reconstituted into ultrathin (<100 nm) films while retaining most of these properties for a wide variety of bioapplications. These ultrathin films can be further...

Low solar absorptivity, space environmentally stable polymeric materials possessing sufficient electrical conductivity for electrostatic charge dissipation (ESD) are of interest for potential applications on spacecraft as thin film membranes on antennas, solar sails, large lightweight space optics, and second surface mirrors. One method of imparting electrical conductivity while maintaining low...

a novel starch/poly (vinyl alcohol)/nano-titanium dioxide (st/pva/nano-tio2) biodegradable nanocomposite film was prepared by homogeneously dispersed tio2 nanoparticles in different ratios of starch/pva-based materials, via a solution casting method. glycerol was used as plasticizer. the mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...

10 Influence of phase composition, structural peculiarities and grain size of Fe2O3–SnO2 nanocomposites prepared by sol–gel technology on gas-sensitive properties of the corresponding gas sensors has been studied in the paper. The characteristics of thin film sensors were obtained with regards to NO2 and C2H5OH. Behaviour of thick film sensors was estimated in humid C2H5OH ambient. High sensiti...

CNT nanocomposites used for thin-film transistors (TFTs) provide one of the first technologically-relevant test beds for 2D heterogeneous percolating systems. The characteristics of these TFTs are predicted by considering the physics of heterogeneous finite-sized networks and interfacial traps at the CNT/gate-oxide interface. Close agreement between our numerical results and different experimen...

The sliding behaviors of two simplified tribofilms with amorphous structure consisting either of SiO2 molecules or C atoms were simulated by molecular dynamics modeling. The objective was to identify mechanisms explaining the experimentally observed lubricating properties of the two amorphous films. The impacts of layer thickness, normal pressure, temperature and different substrate materials w...

In our work we have focused on the incorporation of Prussian Blue nanoparticles (NP) into polyelectrolyte multilayer films (PEM). The main goal of presented studies was to obtain polymer/nanoparticles films with controlled electroactive properties. The amount and ordering of deposited nanoparticles depended on the adsorption conditions of the underlying polymer anchoring layer. In the case of f...
