Nanocomposite carbonaceous-palladium thin films for ammonia sensors

Laser processing of polymer nanocomposite thin films

Current biotechnology and sensor research has enhanced the drive to establish viable methods for depositing high-quality polymer thin films. In this research, thin films of poly methyl methacrylate PMMA were prepared by matrix-assisted pulsed-laser evaporation MAPLE . Up to 2 wt % of carbon nanotubes were subsequently added to MAPLE target systems for deposition of polymer nanocomposite films. ...

Nanocomposite Thin Films for both Mechanical and Functional Applications

The design methodology and realization of nanocomposite films aiming for mechanical (superhardness, toughness) and functional (optical, microelectronic) properties were discussed in this paper. Superhard TiCrCN and nc-TiN/a-SiNx films and super-tough nc-TiC/a-C(Al) films were prepared through co-sputtering method by optimal design of microstructure. The nanocrystalline silicon (nc-Si) passivate...

Surfactant-Assisted Electrodeposition of CoFe-Barium Hexaferrite Nanocomposite Thin Films

The influences of anionic sodium dodecylsulfate (SDS) and cationic Hexadecyltrimethylammonium bromide (HTAB) surfactants on the incorporation and distribution of barium hexaferrite nanoparticles in the electrodeposited CoFe-BaFe12O19 composite thin films were studied. Sulphate bathes with natural pH containing 0 to 2 g/L surfactants were used for electroplating at room temperature. Field emissi...

Nanocrystalline mesoporous palladium activated tin oxide thin films as room-temperature hydrogen gas sensors.

A unique nanocrystalline, mesoporous PdO-SnO(2) film exhibiting high sensitivity and selectivity to hydrogen gas at room temperature has been developed.
