Researchers use oxides to flip graphene conductivity

By demonstrating a new way to change the amount of electrons that reside in a given region within a piece of graphene, scientists have a proof-of-principle in making the fundamental building blocks of semiconductor devices using the 2D material.

Engineering self-assembling amyloid fibers

Researchers have come up with methods to manipulate natural proteins so that they self-assemble into amyloid fibrils.

Solid or liquid - the nanoparticle size matters

Researchers elucidate how the phase state of aerosol nanoparticles depends on their size.

Electronic circuits with reconfigurable pathways closer to reality

Will it be possible one day to reconfigure electronic microchips however we want, even when they are in use? A recent discovery suggests as much. The researchers have demonstrated that it is possible to create conductive pathways several atoms wide in a material, to move them around at will and even to make them disappear.

Nanoshuttle wear and tear: It's the mileage, not the age

Researchers observed a molecular shuttle powered by kinesin motor proteins and found it to degrade when operating, marking the first time, they say, that degradation has been studied in detail in an active, autonomous nanomachine.

Researchers make magnetic graphene

Researchers have found an ingenious way to induce magnetism in graphene while also preserving graphene's electronic properties. They have accomplished this by bringing a graphene sheet very close to a magnetic insulator - an electrical insulator with magnetic properties.

Chemists control structure to unlock magnetization and polarization simultaneously

Chemists have controlled the structure of a material to simultaneously generate both magnetisation and electrical polarisation, an advance which has potential applications in information storage and processing.
