Analyst Viewpoint Introduction of new fluorescent copper nanoparticles to boost the market for metal and metal oxide nanoparticles The introduction of the very new fluorescent copper nanoparticles (F-CuNP) has received great attention owing to their over attractive features such as water solubility good biocompatibility and ease of functionality

with copper (II) oxide and it is very likely the product is in fact copper (II) oxide A larger sample for the XRD analysis would confirm this result The EDS shows major peaks of copper and oxygen at a one-to-one ratio The largest peak corresponds to the silicon substrate on which the sample was deposited The one-to-one ratio of copper to

CUPRITE Copper Oxide Cuprite has been a major ore of copper and is still mined in many places around the world Of all the copper ores except for native copper cuprite gives the greatest yield of copper per molecule since there is only one oxygen atom to every two copper atoms READ MORE

BHP pulls ahead of rival Rio Tinto with a major copper

The copper race is on between long-time rivals BHP (ASX BHP) and Rio Tinto (ASX RIO) with BHP announcing it had pulled out of the ground what some experts call the thickest high-grade copper intersection seen in many years near its Olympic Dam mine in South Australia The mining giant reported a whopping mineralised intersection of 425 7m comprising copper gold uranium and silver from
