Experts in the Nanoscale and Microscale Research Centre (nmRC) at the University of Nottingham have taken a first peak into the private life of atomic clusters.
The interface of the solid anode and the liquid electrolyte plays a crucial role in the performance of a lithium-metal battery, but characterizing the processes that happen at that intersection has been a challenge.
Rice University researchers have found that fracture-resistant "rebar graphene" is more than twice as tough as pristine graphene.
A new microscopy technique developed at the University of Illinois at Chicago allows researchers to visualize liquids at the nanoscale level—about 10 times more resolution than with traditional transmission electron microscopy—for ...
Two high-speed electron microscopes. 7,062 brain slices. 21 million images.
Diatoms are tiny, unicellular creatures, inhabiting oceans, lakes, rivers, and soils. Through their respiration, they produce close to a quarter of the oxygen on earth, nearly as much as the world's tropical forests. In addition ...
All matter is composed of atoms, which are too small to see without powerful modern instruments including electron microscopes. The same electrons that form images of atomic structures can also be used to move atoms in materials. ...
Plants containing the element gold are already widely known. The flowering perennial plant alfafa, for example, has been cultivated by scientists to contain pure gold in its plant tissue. Now researchers from the Sun Yat-sen ...
Researchers take a deep look into a diamond to see how the atoms in its platelet defects are arranged in the hardest natural material known to man.
