A poly(acrylic acid)±surfactant±multi-walled carbon nanotube complex was prepared and characterized using transmission electron microscopy, scanning electron microscopy, wide-angle X-ray di€raction and small-angle X-ray di€raction. The complex was found to retain a lamellar structure, and helped micrometer-length multi-walled carbon nanotube dissolve in(More)
Deposition technology of transparent conducting oxide (TCO) thin films is critical for high performance of optoelectronic devices. Solution-based fabrication methods can result in substantial cost reduction and enable broad applicability of the TCO thin films. Here we report a simple and highly effective solution process to fabricate indium-tin oxide (ITO)(More)
Ž . Several polymer-coated and polymer-grafted multi-walled carbon nanotubes MWNTs were synthesized and characterized using TEM and HRTEM. The polymer-coated or polymer-grafted MWNTs formed stable solutions in DMF. Their nonlinear optical properties were investigated using 532 nm nanosecond laser pulses. These polymer–MWNT composites still possess strong(More)
The size-fractionation of multi-walled carbon nanotube (MWNT) in the dimethylformamide (DMF) solution of poly(vinylidene fluoride) (PVDF) has been achieved by controlled sonication–centrifugation cycles. The Z-scan experiments and fluence-dependent transmission measurements with nanosecond laser pulses of 532 nm wavelength show that the optical limiting(More)
Sword-like anatase TiO2 nanobelts exposed with 78% clean {100} facets were synthesized and the facet-dependent photoreactivity of anatase TiO2 was investigated. By quantitative comparison with the reference {001} facets, the {100} facets possessed about ten-times higher active sites density than that on {001} facets, resulting in higher photoreaction(More)
Ullmann coupling of 4-bromobiphenyl thermally catalyzed on Ag(111), Cu(111), and Cu(100) surfaces was scrutinized by scanning tunneling microscopy as well as theoretical calculations. Detailed experimental evidence showed that initial formation of organometallic intermediates on the surface, as self-assembled structures or sparsely dispersed species, is(More)
