An international team of researchers has demonstrated the first “quantom-dot-in-nanowire” system, a breakthrough that holds enormous potential for solar photovoltaics, energy-efficient lighting, and quantum computing.
For more than a decade, scientists have tried to improve lithium-based batteries by replacing the graphite in one terminal with silicon, which can store 10 times more charge. But after just a few charge/discharge cycles, the silicon structure would crack and crumble, rendering the battery useless. Now a team led … [continued]
Researchers at North Carolina State University have used nano-engineering technology to develop new superstrong aluminum alloys with a plastic-like ability to stretch under stress. The new material could help lower the cost of solar power installations, and it also has the potential to replace far heavier metals such as steel … [continued]
