Electrocatalytic Reduction of Oxygen: Gold and Gold-Platinum Nanoparticle Catalysts Prepared by Two-Phase Protocol
Gold Gold-Platinum
2009/7/29
This paper describes recent results of an investigation
of gold (Au) and gold-platinum (AuPt) nanoparticle
electrocatalysts for fuel cell reaction at the cathode,
i.e., oxygen reduction reaction (O...
Gold nanoparticle assemblies: interplay between thermal effects and optical response
Gold nanoparticle assemblies thermal effects
2009/7/28
Gold nanoparticle assemblies present an optical
response which is very sensitive to different
phenomena of thermal origin. In a recent paper, we
have described how the interaction of light with
ma...
Optical detection and spectroscopy of single gold
nanoparticles using the spatial-modulation
spectroscopy technique is described, focusing on the
connection between the nanoparticle and
environmen...
Impacts of gold nanoparticle exposure on two freshwater species: a phytoplanktonic alga（Scenedesmus subspicatus）and a benthic bivalve（Corbicula fluminea）
gold nanoparticles Corbicula fluminea Scenedesmus subspicatus
2009/7/28
For years, nanotechnologies have developed the
use of common materials, such as iron or silica,
at an extremely small scale because of their
new properties (reactivity, conductivity, optical
sensi...
Gold nanoparticle assemblies: Thermal behaviour under optical excitation
Gold nanoparticle assemblies
2009/7/28
The optical response of materials based on gold
nanoparticle assemblies depends on many
parameters connected to both material morphology
and light excitation characteristics. The optical
energy ab...
Electron microscopy studies of the thermal stability of gold nanoparticle arrays
thermal stability gold nanoparticle arrays
2009/7/28
A series of monolayer protected gold nanoparticlecolloidal solutions have been prepared with averagesizes in the 2-15nm range. If a drop of such acolloidal suspension is deposited onto a Si3N4substrat...
