Graphenes now go monolayer and single crystalline

IBS-CMCM scientists have reported a truly single layer (i.e., adlayer-free) large area graphene film on large area copper foils. They refined the chemical vapor deposition (CVD) growth method by eliminating all carbon impurities ...

Do microbes control the formation of giant copper deposits?

One of the major issues when studying ore deposits formed in surficial or near-surface environments is the relationship between ore-forming processes and bacteria. At a first glance, these environments appear to be a preferred ...

Copper-bottomed deposits

The world's most valuable copper deposits, known as porphyry deposits, originate from cooling magma. But how can we predict the size of these deposits? What factors govern the amount of copper present? Researchers at the ...

Modeling magma to find copper

Copper is an essential element of our society with main uses in the field of electricity and electronics. About 70% of the copper comes from deposits formed several million years ago during events of magma degassing within ...

New technique to find copper deposits

A geologist at the University of Exeter has developed a new and relatively inexpensive way to establish whether certain types of magmatic rocks are more likely to contain valuable metal deposits.

A climate signal in the global distribution of copper deposits

Climate helps drive the erosion process that exposes economically valuable copper deposits and shapes the pattern of their global distribution, according to a new study from researchers at the University of Idaho and the ...

Hybrid nanowires eyed for computers, flexible displays

A new process for coating copper nanowires with graphene - an ultrathin layer of carbon – lowers resistance and heating, suggesting potential applications in computer chips and flexible displays.
