By using one of the world’s most powerful electron microscopes, a team of researchers from Lawrence Berkeley National Laboratory has successfully mapped the exact location and chemical type of 23,000 atoms in a nanoparticle made of iron and platinum. The team believes this work could reveal more information about material properties at the single-atom level, opening the doors to improving magnetic performance for next-generation hard drives.
A team of scientists have recently discovered how to produce ultra-thin “diamond nanothreads.” These nanothreads, which construct a structure more than 20,000 times smaller than average human hair, are expected to yield extraordinary properties. The new nanothreads will be stronger and stiffer than current nanotubes, and they will also be light in weight.
This means creating the potential for more fuel efficient vehicles, and even fictional-sounding endeavors – such as a “space elevator.”

The team—led by John Badding, a chemistry professor at Penn State University and his student Thomas Fitzgibbons—used a specialized large volume high pressure device to compress benzene up to 200,000 atmospheres, at these enormous pressures, benzene spontaneously polymerizes into a long, thin strands of carbon atoms arranged just like the fundamental unit of diamond’s structure—hexagonal rings of carbon atoms bonded together, but in chains rather than the full three-dimensional diamond lattice.
