Three years after the first experimental results, graphene promises more fascinating physics and dream applications.
Reducing the operating voltage and power consumption of organic-based logic circuits for portable applications is a critical step towards the commercialization of organic electronics.
The future of quantum computing relies on keeping information in quantum spin phases. A study of molecular nanomagnets shows that their dephasing time may be more suitable than previously thought.
Raman spectroscopy experiments show that the interaction between electrons and phonons in graphene resembles the Dirac fermion–photon coupling in quantum electrodynamics.
Despite intense research efforts, no three-dimensional materials with a photonic bandgap for visible wavelengths have yet been fabricated. A new self-assembly strategy lays out the route towards the realization of this dream.
An explanation for the need of a reduction process in electron-doped superconductors offers new insight into the conductivity mechanism of these lesser-known superconductors.
Simulations of nanoscale sharp tips sliding on a salt surface predict vanishing friction at temperatures close to the melting temperature, as the tip skates on a layer of liquefied salt. This insight opens the way to applications in MEMS, NEMS and auto/aerospace engines.
Ice, silicon and oxide glasses can show amorphous phases of distinct densities. Based on changes in atomic bond lengths, a similar polyamorphism has now been observed in structurally different metallic glasses.
