A special method of electrodialysis has been developed for investigation of the kinetics and mechanism of polymerization reactions involving ions. The ionic composition of homogeneous systems such as CpzTiRClAlRC12, RTiC13 + AlRC12, Ti(OR)4 + AIRS, and (RLi), has been studied. The composition of cat

Structural changes which accompany the catalytic graphitization of carbon have been investigated. Utilizing X-ray diffraction and high temperature microscopy techniques, the effectiveness of various additives in promoting the formation of graphite from a variety of carbon materials of varying degree
The Raman spectra of carbon nanotubes prepared by catalytic (C-CNT) and d.c. arc discharge (D-CNT) methods are reported. A previously unnoticed third-order Raman peak at ca. 4248 cm-1 was observed in the Raman spectrum of D-CNT. The Raman features of D-CNT and C-CNT are similar to those of highly or
