Autor: V. V. Menshenin, G. A. Emelchenko, V. N. Churmanov, Victor I. Sokolov, N. B. Gruzdev

Publikováno v: Low Temperature Physics. 47:32-38

The impurity absorption in Zn1−xMnxO is formed by dipole allowed p-s transitions from deep antibonding p-d hybrid (pdh) state to the conduction band. In this paper, photoluminescence of Zn1−xMnxO single crystals was investigated in the temperatur

Phase transformations in opals under thermal and thermobaric actions

Autor: M. N. Shushunov, V. P. Filonenko, V. M. Masalov, V. A. Somenkov, G. A. Emelchenko, S. S. Agafonov

Publikováno v: Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques. 11:634-638

The ultrasmall- and wide-angle neutron diffraction methods are used to study multiscale structures and phase transformations in synthetic opals at different temperatures and pressures (as high as 1500°C and 10 GPa, respectively). Monodisperse colloi

Autor: Rumin Li, Lichao Tan, Hongsen Zhang, Jingyuan Liu, Dalei Song, Xiaoyan Jing, Jun Wang, Qi Liu, G. A. Emelchenko, Jiahui Zhu

Publikováno v: Dalton transactions (Cambridge, England : 2003). 45(22)

A novel rod-like, dual-shell structural adsorbent of polypyrrole/cobalt ferrite/multiwalled carbon nanotubes (PPy/CoFe2O4/MWCNTs) was successfully synthesized by a hydrothermal method, which could easily separate uranium(VI) ions with an external mag
