Nanoscale fast Ge diffusion in laser irradiated SiGe thin films

Teodorescu V.S., Ghica C., Maraloiu A.V., Lepadatu A.M., Stavarache I., Ciurea M.L., Scarisoreanu N.D., Andrei A., Dinescu M., National Institute for Materials Physics, RO

We report the presence of a fast Ge diffusion effect produced during laser crystallization of Si0.45Ge0.55 films deposited by magnetron sputtering on Si(100) substrates. The laser irradiation was performed using the 265 nm wavelength radiation [...]

TiO2-based photocatalytic and antimicrobial coatings: comparison between sol-gel and electrodeposited silver/TiO2 nano-composites

Diamanti M.V., Magagnin L., Del Curto B., Candiani G., Pedeferri MP., Politecnico di Milano, IT

Among possible ways to improve air quality in urban atmospheres, the use of nanostructured TiO2 films as photocatalysts is an excellent way to mitigate the problem, although it cannot offer a complete solution. TiO2 also [...]

Ultrasonic Spraying of Carbon Nanotubes using NMP

Willey A., Davis R., Vanfleet R., Brigham Young University, US

We will present a new method for spraying thin films of carbon nanotubes, in which they are suspended in an organic solvent and then sprayed ultrasonically onto a heated substrate. These thin films have applications [...]

Crystallization and optical properties of CCTO thin films under pressure influence

Sequinel T., Tebcherani S.M., Varela J.A., Kubaski E.T., Oliveira L.H., Siu Li M., Universidade Estadual Paulista, BR

The goals of this work were to decrease the synthesis temperature of CCTO thin films using the pressure method, and to improve the homogeneity and density of the CCTO films in order to obtain better [...]

New approaches of soft chemistry for preparation of nanostructured multifunctional composite coatings

Vinogradov A.V., Vinogradov V.V., Vinogradov A.V., Vinogradov V.V., Agafonov A.V., Institute of Solution Chemistry RAS, RU

In this work, we have obtained film heterostructures such as MeO/TiO2 possessing high photoactivity by low-temperature sol-gel method. We have succeeded in obtaining photoactive TiO2-based crystalline coatings, FeTiO3 and CoTiO3, without calcination and possessing an [...]
