Researchers used an advanced scanning transmission electron microscope to measure isotopes in nanometer-sized areas of a graphene sample. The same energetic electrons that form an image of the graphene structure can also eject one atom at a time due to scattering at a carbon nucleus.
Scientists fed the silkworms mulberry leaves coated in a solution that contained graphene in order to create the material. Applications for the material created include wearable electronics, durable fabrics and biodegradable medical implants.
Researchers succeeded in improving the energy density of a rechargeable battery without increasing its size. This feat was achieved by developing a 3D structure made of microtubes, the first step towards producing a complete microbattery.
Technology may be able to succeed where hard-working volunteers have failed in the past. Researchers are using nanotechnology to turn an oil spill into a floating mass of brown jelly that can be scooped up before it can make its way into the food chain.
Electrons are far too small and fast to be seen, even with the help of a light microscope. This has made measuring an electron's movement very difficult for the past century. However, new research has made this process much easier.
In a combination of experiments and theory the diffusion of individual atoms in periodic systems was understood for the first time. The interaction of individual atoms with light at ultralow temperatures close to the absolute zero temperature point provides new insights into ergodicity, the basic assumption of thermodynamics.
Researchers have designed a device that uses light to manipulate its mechanical properties. The device, which was fabricated using a plasmomechanical metamaterial, operates through a unique mechanism that couples its optical and mechanical resonances, enabling it to oscillate indefinitely using energy absorbed from light.
Researchers have discovered how to subtly change the interior structure of semi-hollow nanorods in a way that alters how they interact with light, and because the changes are reversible, the method could form the basis of a nanoscale switch with enormous potential.
Scientists have developed a multi-layered 'sensing skin' to detect corrosive or otherwise harmful substances in structures. The skin can also detect cracks and other structural flaws that are invisible to the naked eye.
Researchers have developed methods to control defects in two-dimensional materials, such as graphene, that may lead to improved membranes for water desalination, energy storage, sensing or advanced protective coatings.
