ALD and CVD deposition of pure thin gold films from a stable dimethylgold(III) precursor.

The synthesis and thermal properties of a volatile dimethylgold(III) complex MeAuSSP(OPr) are reported. Unlike most other volatile Au(I) and Au(III) compounds, the complex is stable upon storage, does not require any special handling conditions, and exhibits both good volatility and thermal stability. The compound was tested as a CVD and ALD precursor, yielding good quality films in both processes.

Facile Fabrication of Gold Nanorods@Polystyrenesulfonate Yolk-Shell Nanoparticles for Spaser Applications.

We present a method for producing gold nanorods surrounded by a hollow polymeric shell of polystyrenesulfonate and show that the cavities of such particles can be filled with various organic dyes. The approach consists of covering gold nanorods with silica, followed by its slow hydrolysis in an aqueous medium in the presence of the polymer thin layer permeable for dye molecules. The proposed method enables the yolk-shell nanoparticles to be obtained and loaded with organic dyes without a need to use thermal treatment and/or chemical etching, which makes it suitable for use in the creation of spasers.

Amorphous AlN films grown by ALD from trimethylaluminum and monomethylhydrazine.

The great interest in aluminium nitride thin films has been attributed to their excellent dielectric, thermal and mechanical properties. Here we present the results of amorphous AlN films obtained by atomic layer deposition. We used trimethylaluminum and monomethylhydrazine as the precursors at a deposition temperature of 375-475 °C.

Lasing Spaser in Photonic Crystals.

Plasmonic nanolasers (spasers) are of intense interest, attributable to their ability to generate a high-intensity coherent radiation. We infiltrated a three-dimensional silica-based photonic crystal (PhC) film with spasers, composed of spherical gold cores, surrounded by silica shells with dye molecules. In spasers, the gold nanospheres supported the surface plasmons and the dye molecules transferred incoming optical energy to the surface plasmons.

Changes of the Heart Valves in the Long Term After Chemoradiotherapy According to Different Protocols for Hodgkin's Lymphoma in Children and Adolescents.

The purpose of our work was to study late cardiac complications after treatment for Hodgkin's lymphoma (HL) in children and adolescents. Sixty-seven patients were examined in the long term (>5 years) after chemoradiotherapy for HL according to two different programs of treatment (groups I and II). Mean total doses of radiotherapy (RT) to the mediastinum were 37.
