Isolated hydrogen atoms absorbed on graphene are predicted to induce magnetic moments. Here we demonstrate that the adsorption of a single hydrogen atom on graphene induces a magnetic moment characterized by a ~20-millielectron volt spin-split state at the Fermi energy. Our scanning tunneling microscopy (STM) experiments, complemented by first-principles(More)
Carbon and silicon pentagonal low-dimensional structures attract a great interest as they may lead to new exotic phenomena such as topologically protected phases or increased spin-orbit effects. However, no pure pentagonal phase has yet been realized for any of them. Here we unveil through extensive density functional theory calculations and scanning(More)
Sweet sorghum (Sorghum bicolor (L.) Moench) bagasse is a lignocellulosic material consisting mainly of hemicellulose and cellulose, a potential source of fermentable sugars. The present study aimed to optimize the hydrolysis of sweet sorghum bagasse to obtain the highest concentrations of xylose and glucose with the minimum amount of inhibitor compounds.(More)
UNLABELLED Scanning probe microscopy (SPM) is already a relevant tool in biological research at the nanoscale. We present 'Flatten plus', a recent and helpful implementation in the well-known WSxM free software package. 'Flatten plus' allows reducing low-frequency noise in SPM images in a semi-automated way preventing the appearance of typical artifacts(More)
By merging bottom-up and top-down strategies we tailor graphene's electronic properties within nanometer accuracy, which opens up the possibility to design optical and plasmonic circuitries at will. In a first step, graphene electronic properties are macroscopically modified exploiting the periodic potential generated by the self assembly of metal cluster(More)
