Researchers create 'nanoflowers' for energy storage, solar cells
(Phys.org)—Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous ...
The curious case of germanium-72: An unusual isotope changes phases as temperature rises
(PhysOrg.com) -- There's a lot we don't know about the atomic nucleus, even though it was discovered a century ago this year.
Magical BEANs: New nano-sized particles could provide mega-sized data storage
The ability of phase-change materials to readily and swiftly transition between different phases has made them valuable as a low-power source of non-volatile or “flash” memory and data storage. Now an ...
