Ag-Ag 2 S/reduced graphene oxide hybrids used as long-wave UV radiation emitting nanocomposites

open access: yes, 2017
We report a facile thermal decomposition approach to synthesize Ag-Ag2S/reduced graphene oxide (Ag-Ag2S/rGO), the Ag-Ag2S nanoparticles uniformly dispersed on reduced graphene oxide with diameters of 10–20 nm. The photoluminescence spectra of Ag-Ag2S/rGO

Embedded layer of Ag nanoparticles prepared by a combined PECVD/PVD process producing SiOxCy-Ag nanocomposite thin films. [PDF]

open access: yes, 2011
Structural properties of SiOxCy–Ag nanocomposite thin films prepared by a dual process PVD–PECVD in the same reactor have been investigated. The experimental results have demonstrated the influence of a PECVD process carried out at room temperature for ...

The future of Age and Ageing [PDF]

open access: yesAge and Ageing, 2002
The delivery of healthcare in the United Kingdom is going through a period of change, with many new developments. Some of these represent the aspirations of politicians and those who manage the National Health Service, and others are being forced upon us because of the shortage of resources (not always financial).
