\n\tChalmers University of Technology, Sweden, announces that its researchers have shown that carbon nanomaterials such as graphene can replace expensive metals such as tin, silver, tungsten, beryllium, and indium in electronic devices.<\/p>\n
\n\tRickard Arvidsson and Bj\u00f6rn Sand\u00e9n have investigated whether the carbon nanomaterials graphene, fullerenes, and carbon nanotubes have the potential to replace 14 scarce metals in several areas of application. They found potential technology-based solutions to replace the metals with carbon nanomaterials for all applications except for gold in jewelry. The metals closest to being able to substitute are indium, gallium, beryllium, and silver.<\/p>\n
\n\t“Today there are many new carbon nanomaterials with similar properties to metals,” says Dr. Sand\u00e9n. “It’s a welcome new track, and it’s important to invest in both the recycling and substitution of scarce metals from now on.”<\/p>\n
