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 ...

Making a movie of nanocrystal structural evolution

When you rapidly turn the pages of a flipbook, the series of static images look like they are moving. Scientists recently applied a similar principle to capture how the structure of a material changes over extremely short ...

Developing new ways to advance copper production

MIT associate professor of metallurgy Antoine Allanore has received a $1.9 million grant from the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE) to run larger scale tests of a new way ...

A designer's toolkit for constructing complex nanoparticles

A team of chemists at Penn State has developed a designer's toolkit that lets them build various levels of complexity into nanoparticles using a simple, mix-and-match process. "Researchers in areas as diverse as medicine, ...

Team develops sodium ion batteries using copper sulfide

A KAIST research team recently developed sodium ion batteries using copper sulfide anode. This finding will contribute to advancing the commercialization of sodium ion batteries (SIBs) and reducing the production cost of ...

Nanocage surfaces get 'makeover' in room temperature

Kyoto University researchers have discovered a way of replacing surface ions of copper oxide nanocrystals at ambient conditions—a feat that will make nanocage production considerably simpler.

Reinventing copper extraction with electricity

Copper is so valuable that its theft from worksites and power substations has become a national problem. Replacing the lost copper with new metal produced by the traditional method of cooking copper sulfide ores requires ...
