Valery A. Davydov,A. V. Rakhmanina,Igor I. Kireev,Irina B. Alieva,Oksana Zhironkina,Olga Strelkova,Varvara Dianova,Taraneh Djavanbakht Samani,Karina Mireles,L. 'Hocine Yahia,Rustem Uzbekov,Rustem Uzbekov,Viatcheslav N. Agafonov,Valery N. Khabashesku +13 more
TL;DR: The internalization of Fe7C3@C NPs has no cytotoxic effect on cultured cells and does not interfere with the process of their mitotic division, a fundamental property that ensures the existence of living organisms.

Valery N. Khabashesku,Zhenning Gu,Bruce E. Brinson,and John L. Zimmerman,John L. Margrave,Valery A. Davydov,and Lyudmila S. Kashevarova,A. V. Rakhmanina +7 more
TL;DR: In this article, a survey study of pressure−temperature-induced transformations of single-wall carbon nanotubes (SWNT) at 1.5, 8.0, and 9.5 GPa and temperatures ranging from 200 to 1500 °C in a piston-cylinder or Toroid type high pressure devices has been carried out.
