Substitutional Doping of Carbon Nanotubes
TL;DR: In this paper, the substitutional placement of boron within the lattice of carbon nanotubes can yield quite different electronic properties for (SWNT) single walled and (MWNT) multi-walled nanotsubes.
Journal ArticleDOI
Short Time Transport Phenomena in Polyacetylene
TL;DR: In this paper, high frequency AC (up to 10 THz) conductivity and short time photoconductivity (25 ps Illumination, 100 ps resolution) measurements are reported, interpreted as hopping between localized states and argued that due to a variety of imperfections of polymeric samples these states can not be identified, especially not as solitons.

TL;DR: In this article, the transformation of single-walled carbon nanotubes into diamond by ab initio calculations and high pressure and temperature experiments was studied and the formation of hexagonal diamond as a high pressure nanotube phase was predicted.

TL;DR: The present investigation involved the synthesis of a number of novel benzylidene hydrazides as candidate cytotoxic agents and screened against human HCT116 and HT29 colon cancer cells as well as human CRL1790 non-malignant colon cells which revealed the tumor-selective toxicity displayed by these compounds.
