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.
Entanglement on a chip: Breakthrough promises secure communications and faster computers
A team of scientists has developed, for the first time, a microscopic component that is small enough to fit onto a standard silicon chip that can generate a continuous supply of entangled photons.
Nanodiamonds may provide more effective cancer treatment
A new study shows that when the chemotherapy drug Epirubicin is attached to nanodiamonds, the treatment is more effective and patients suffer from less side effects.
Visualizing interacting electrons in a molecule
Scientists have succeeded in directly imaging how electrons interact within a single molecule.
Detecting cancer at the atomic level
Igor Sokolov's nanoscale research could yield better ways to identify and track malignant cells.
Chromium-centered cycloparaphenylene rings for making functionalized nanocarbons
Chemists have synthesized novel transition metal-complexed cycloparaphenylenes (CPPs) that enable selective monofunctionalization of CPPs for the first time, opening doors to the construction of unprecedented nanocarbons.
Graphene enables electrical control of energy flow from light emitters
Scientists from Europe's Graphene Flagship have demonstrated active, in-situ electrical control of energy flow from erbium ions into photons and surface plasmons.
