Journal of Perioperative Practice, 2006
The term evidence-based practice is not new. For over twenty years the debate has been ongoing about how to make it happen. To practice within an evidence base, practitioners must determine if the evidence available is relevant for the particular patient (DiCenso et al 1998).

A study of the nucleation and growth processes in the synthesis of colloidal gold
, 1951After a preliminary survey with the electron microscope of various preparations of colloidal gold, a study was made of the process of nucleation and growth in gold colloids. It was shown that nucleating agents may be identified with reducing agents which

Tracing gold back to its source by means of the elemental composition of objects contributes to the knowledge of the trade routes used in the past. The analysis of a large number of ancient gold objects showed that in most cases only a few elements are useful to characterize the metal.

Determination of size and concentration of gold nanoparticles from UV-vis spectra.
Analytical Chemistry, 2007The dependence of the optical properties of spherical gold nanoparticles on particle size and wavelength were analyzed theoretically using multipole scattering theory, where the complex refractive index of gold was corrected for the effect of a reduced ...

Within the wide family of gold-catalyzed reactions, gold photocatalysis intrinsically features unique elementary steps. When gold catalysis meets photocatalysis, a valence change of the gold center can easily be achieved via electron transfer and radical

Synthesis of thiol-derivatised gold nanoparticles in a two-phase liquid-liquid system
, 1994Using two-phase (water–toluene) reduction of AuCl4– by sodium borohydride in the presence of an alkanethiol, solutions of 1–3 nm gold particles bearing a surface coating of thiol have been prepared and characterised; this novel material can be handled as

Adsorption and surface-enhanced Raman of dyes on silver and gold sols
, 1982Several negatively charged dyes were investigated for their possible adsorption on the surface of silver and gold colloidal particles. Those dyes that were found to adsorb on the particles were then checked for surface enhancement of Raman scattering ...
