In this work, the stability and transformation of two kinds of TiC with different stoichiometries in Cu–Si melts are studied, respectively. It is found that the near-stoichiometirc TiC with fewer carbon vacancies (designated as TiCx), such as TiC0.9, is relatively stable in Cu–Si melts, while the non-stoichiometric TiC with more carbon vacancies (designated as TiCy), such as TiC0.6, is unstable. And...
A new type of water‐soluble single‐walled carbon nanotubes (SWNTs) was synthesized by grafting of dodecyl quaternary ammonium bromides. Results of Fourier transform infrared and proton nuclear magnetic resonance spectroscopic analyses confirmed the successful synthesis. Water‐soluble performance of functionalized SWNTs, i.e. N+‐SWNTs, has been studied in terms of solubility and stability. It was found...
