The wings of the butterfly Pachliopta aristolochiae are drilled by nanostructures (nanoholes) that help absorbing light over a wide spectrum far better than smooth surfaces. Researchers have now succeeded in transferring these nanostructures to solar cells.
The spins of unpaired electrons are the root of permanent magnetism, and after 10 years of design and re-design, researchers have made a molecule that gains magnetic strength through an unusual way of controlling those spins.
A new way to observe this deformation as it happens can help study a wide range of phenomena, from meteor impacts to high-performance ceramics used in armor, as well as how to protect spacecraft from high-speed dust impacts.
In a unique experiment, researchers have clocked how long it takes for an electron to be emitted from an atom. The result is 0.000 000 000 000 000 02 seconds, or 20 billionths of a billionth of a second.
A new study outlines the design of a synthetic system for energy gathering, conversion and transport that may point the way to innovations in solar energy, materials science, nanotechnology and photonics.
