We report a quantitative detection of the charge properties of few- layer graphene by surface potential measurements using electrostatic force microscopy (EFM). A minor difference in surface potential is observed to mediate a sequential assembly of metal-free phthalocyanine (H2Pc) on monolayer, bilayer and trilayer graphenes, as demonstrated by scanning tunneling microscopy (STM). This abnormal assembly behavior is further investigated by density functional theory (DFT) calculations.

Using an atomic force microscope, we have studied the deformation of atomically thin sheets (2 to 14 layers) of muscovite mica to determine whether or not they are suitable for future flexible electronic applications. Ultrathin mica shows low pre-tension, high Young's modulus (190 GPa) and withstands large deformations without breaking which allows their use in applications requiring flexible dielectric materials.

Address correspondence to

The lithium-encapsulated fullerenol Li@C60(OH)18 has been synthesized, as clearly evidenced by 7Li NMR spectroscopy. The more anionic surface of Li@C60(OH)18 induced by the inner lithium cation, as compared with that of empty C60(OH)16, resulted in a high degree of dispersal in polar solvents, and thus the molecule (with a diameter of ca. 1.5 nm) can be described as a ※cation-encapsulated anion nanoparticle§.
