First published in 1883, this travel memoir describes the journey into West Africa undertaken by explorers Richard Burton (1821–90) and Verney Lovett Cameron (1844–94) in 1881. The mission for the two men was to assess the mining potential of the west coast, first observed by Burton in a publication that had appeared twenty years earlier. The first few

Gold nanospirals on colloidal gold nanoparticles
Journal of Colloid and Interface Science, 2019Synthesis of asymmetric nanostructures has always been a great challenge. In particular, there are only limited approaches for growing spiral nanowires in solution, and almost all of them require templates. Here, as a step in advancing the synthetic capability at the nanoscale, we report a wet chemistry template-free approach for growing hybrids spiral

The high stability of gold makes its surface an attractive substrate for the deposition of molecular materials and their functioning in devices. There are many substantial and profound experimental and theoretical issues that the use of any metal interacting with molecules requires to address.

The Economics of Gold and Gold Mining [PDF]
, 1987 Gold mining and placering reach back into antiquity to a time at least more than 4,000 years before our era. During primitive times the winning of gold was a haphazard activity, nuggets of the native metal being plucked from some auriferous stream, the oxidation zones of gold or sulfide deposits, or from residuum near such deposits.
