Effects of Biological Systems on Metallic Gold.
Chemical specifications for high purity gold have grown increasingly stringent as manufacturers strive to improve quality control. Once 999.9-fine grain and bullion bars were accepted without question...
In atoms of high nuclear charge (Z), as a consequence of a relativistic effect, the s electrons of an atom become more bound and their orbitals smaller than if this effect were absent. Simultaneously,...
Effects of Au Nanoparticles on TiO2 in the Photocatalytic Degradation of an Azo Dye
Au Nanoparticles Photocatalytic Degradation
2009/7/28
The photocatalytic activity of Au modified titanium
dioxide was evaluated in the photodegradation of
the azo dye Acid Red 1 (AR1) under 254 nm
irradiation. Noble metal nanoparticles were
deposited...
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...
Support effects in the selective gas phase hydrogenation of p -chloronitrobenzene over gold
Gold catalysts p -chloronitrobenzene hydrogenation p-chloroaniline
2009/7/28
The catalytic continuous gas phase hydrogenation ofp-chloronitrobenzene (P = 1 atm; T = 423 K) has beeninvestigated over a series of oxide (Al2O3, TiO2, Fe2O3and CeO2) supported Au (1 mol %) catalysts...
