We present the science and technology roadmap for graphene, related two-dimensional
crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts …

Carbon nanomaterials are a class of low-dimensional materials that have aroused a great
deal of interest in the past 30 years since the spectacular debut of fullerene, the first member …

Graphene is one of the most promising materials in nanotechnology. The electronic and
mechanical properties of graphene samples with high perfection of the atomic lattice are …

A common misconception is that the irradiation of solids with energetic electrons and ions
has exclusively detrimental effects on the properties of target materials. In addition to the …

Irradiating solids with energetic particles is usually thought to introduce disorder, normally
an undesirable phenomenon. But recent experiments on electron or ion irradiation of …

We report ferromagnetism in carbon-doped ZnO. Our first-principles calculations based on
density functional theory predicted a magnetic moment of 2.02 μ B per carbon when carbon …

Understanding the mechanism of ferromagnetism in carbon-based materials, which contain
only s and p electrons in contrast to traditional ferromagnets based on 3 d or 4 f electrons, is …

X-ray photoelectron spectroscopy (XPS) is among the most powerful techniques to analyze
defective structures of carbon materials such as graphene and activated carbon. However …

Molecular nanocarbons containing heptagonal rings have attracted increasing interest due
to their dynamic behavior, electronic properties, aromaticity, and solid‐state packing …

We have studied magnetization of graphene nanocrystals obtained by sonic exfoliation of
graphite. No ferromagnetism is detected at any temperature down to 2 K. Neither do we find …
