When a bicycle gets wet in the rain, the frame and chain become corroded or rusty, which shortens the life of the bike. Oil needs to be regularly applied to prevent this from happening. Battery cells are devices that create ...

Ever smaller and ever more compact—this is the direction in which computer chips are developing, driven by industry. This is why so-called 2-D materials are considered to be the great hope: they are as thin as a material ...

Since World War I, the vast majority of American combat casualties has come not from gunshot wounds but from explosions. Today, most soldiers wear a heavy, bullet-proof vest to protect their torso but much of their body remains ...

Topological insulators (TIs) have an insulating interior and support conducting surface states with additional interfacing properties. The exotic metallic states on their surfaces can provide new routes to generate new phases ...
Some metal oxides, such as nickelates, have a tuneable resistivity, which makes them an interesting material for adaptable electronics and cognitive computing. These materials can change their nature from metallic to insulating. ...

This it is the story of a unique material—made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle. It is also the story of three research groups—two ...

The charge of a single electron, e, is defined as the basic unit of electric charge. Because electrons—the subatomic particles that carry electricity—are elementary particles and cannot be split, fractions of electronic ...

Atomically thin layers of the semimetal tungsten ditelluride conduct electricity losslessly along narrow, one-dimensional channels at the crystal edges. The material is therefore a second-order topological insulator. By obtaining ...
