Zigzag-edged carbon nanoscrolls (ZCNSs) are revealed to have a magnetic ground state from fi rst-principles calculations. Unlike their fl at counterpart—zigzag-edged carbon nanoribbons, which are semiconductors with spindegenerate electronic structure—ZCNSs can be spin-selective semiconductors, metals, semimetals, or even quasi-half-metal or half-metals, with spin filter function.

Low-dimensional molecular crystallites of square columns and nanolamellae of Zn[TCNQ]2(H2O)2 with large areas have been obtained by controlled addition of water. The system can be used as an indicator for the inspection of traces of water and moisture.

Classical coordination chemistry can be used for the non-destructive purification of single-walled carbon nanotubes (SWNTs). The conductivity of fi lms based on the resulting SWNTs was markedly improved in comparison with those obtained using SWNTs purifi ed by oxidizing acid solutions. The transparent and conducting SWNT fi lms have potential applications in optoelectronic devices.

ZnO nanoparticles exerted a cytotoxic effect on the human glioma cell lines A172, U87, LNZ308, LN18, and LN229, whereas no cytotoxic effect was observed on normal human astrocytes.

Monodisperse zirconia nanocrystals (tetragonal: T-ZrO2; monoclinic: M-ZrO2) with finely tuned sizes and phases have been selectively synthesized by a facile solvothermal method. For the first time, a diagram of the size to effective strain was mapped for both T-ZrO2 and M-ZrO2 on the sub 10 nm scale, which may expand our knowledge in understanding the phase stabilities of not only zirconia, but also various other polymorphic nanocrystals.

A CVD method using a high ratio of methanol:ethanol as carbon feed gas results in the growth of high density, long and uniform SWNT arrays on ST-cut single crystal quartz substrates. Obvious “up-shifts” of the G-band frequencies originating from the strong interaction between nanotubes and quartz have been found in the Raman spectra.
