Boy oh boy, the Spanish must’ve been furious when they lost this ship.
Somebody was absolutely minted back in medieval France!
The first images of Viking treasure, stashed in a pot more than 1,000 years ago and buried in a field in Galloway, have been made public by the conservators working to preserve them. The items, including six silver disk brooches, a gold ingot and Byzantine silk, are not currently on display.
At a recent meeting of the of the American Chemical Society, researchers proposed a novel source of valuable metals: waste water. They proposed a method that could be used to extract valuable metals like gold, silver or titanium which end up in waste water plants via the city’s sewage.
There are millions of dollars in gold and other metals in the sewage sludge in major cities. A new study has found that in a city with 1 million inhabitats, there’s as much as $13 million worth of valuable metals, including gold and silver.
The wonder material Graphene, the new wonder material that promises to open a new age in technology, just got a whole lot better. Researchers have reported improved interfacing of graphene with other 2-D materials – basically ‘growing’ graphene on silver. This resulted in an exceptionally pristine sample, presenting opportunities for ultrafast electronics and advanced optics/ “Silver is a widely used
Silver nanoparticles are often used for extensive medical treatments or antimicrobial health tonics. They’re even used in skin care products, which is rather ironic considering they’ve been linked with argyria, a condition in which the skin turns grayish-blue. Although scientists have known for quite a while that too much silver can cause this condition, the exact mechanisms that cause this transformation were
