Worldwide research efforts on plasmons and metamaterials have been growing exponentially for the past ten years. Now, Antonio I. Fernández-Domínguez (IFIMAC), Francisco J. García-Vidal (IFIMAC & DIPC), and Luis Martín-Moreno (ICMA) discuss new directions for the future, such as the use of 2D materials and strong coupling phenomena, which are likely to shape the field […]

Imagine there exist a material in which an electron could be split into two quasiparticles. These two quasiparticles both would carry electric charge, move in opposite directions but could not move backwards. Furthermore these quasiparticles would be massless. And we can give them a fancy name, Weyl fermions. This seems to be at odds with […]

Graphene nanoribbons (GNRs), are strips of graphene with ultra-thin width (<50 nm). Graphene ribbons were introduced as a theoretical model by Mitsutaka Fujita and coauthors to examine the edge and nanoscale size effect in graphene. GNRs are very interesting structures, partly due to their attractive electronic properties. Those properties vary dramatically with changes in the […]

When autumn arrives to temperate climate forests, deciduous trees lose their characteristic green tonalities and start showing a wide spectrum of new colours: yellow, brown, orange, red… Chlorophyll reabsorption takes place in the leaves and carotenoids, present in a lower concentration, are exposed. These pigments are produced in all photosynthetic organisms, fungi and non-photosynthetic bacteria […]

Nanopore DNA sequencing was one the ten scientific breakthroughs of 2016 highlighted by Science magazine. In principle, graphene is the perfect pore material for DNA sequencing . Its monoatomic thickness of 0.35 nm is similar to the DNA base spacing and graphene nanopores can be fabricated with a diameter of only 1.0 nm, about the […]

Carbon has four valence electrons. To fill its octet, it requires four additional electrons, which can be obtained through the formation of four covalent bonds. Carbon forms single, double, and triple bonds to achieve a filled octet. As a result, carbon can have a tetrahedral, trigonal planar, or linear geometry, respectively. A unique feature of […]
