Investment Casting of Gold Jewellery – Surface Properties of Casting.
Surface Enrichment of Low Gold Alloys.
Gold has long been regarded as an “inert” surface and
bulk gold surfaces do not chemisorb many molecules
easily. However, in the last decade, largely through the
efforts of Masatake Haruta, gold pa...
Scope for New Applications for Gold Arising from the Electrocatalytic Behaviour of its Metastable Surface States
Gold Electrocatalytic
2009/7/28
The electrocatalytic behaviour of gold in aqueous
media is surprisingly complex and a novel view of gold
electrode surfaces is proposed to explain the observed
electrochemical responses. The metal ...
