Research Activities : The
group is active in development of molecular structure design
and synthetic approaches to heterometallic metal alkoxide
complexes. The systems studied include oxides as BaTiO3,
MoO3, WO3, Bi2Mo6, LiNbO3, MO-M'2O5 (M= Co, Ni, Mg, Zn; M'=
Nb, Ta) and spinels MAl2O4 (M= Mn-Zn), sulfides as MoS2, and
mixed Mo-Nb and Mo-Re sulfides and nanocomposite materials
with sulfides and oxides introduced into micro- and
mesoporous matrices. Metal silsesquioxane derivatives of
late transition metals are investigated as molecular models
of nanocomposites. Vadim is the Co-Editor of a recent book

Research Activities : Describes the current research projects of the
"sol-gel group" led by G. Westin at Uppsala
University (Until 1 Jan 2000, at Stockholm University).
The research projects span from fundamental to applied
character. The areas involve alkoxide synthesis and characterization
with emphasis on the heterometallic 3d-block and rare-earth
element (mainly Er) containing alkoxides.
Detailed studies on the hydrolysis-condensation reactions of
Detailed studies on the phase evolution of heterometallic
gels on heat-treatment to form oxides.
Studies are made on: Er(Yb) doped wave-guides, Grätzel type
solar cells, ZnO-based varistors, WC-Co and metal-alumina
compacts, transparent, conducting ZnO.Al electrodes,
perovskites (YBaCuO, PZT, PLZT, LaSrNiO, LaSrCoO, CaLaMnO,
LaNiO, niobates, MnYO), metal nano-particles in alumina
matrixes, photo and thermo catalysis, nano-structures films
(TiO2, TiO2-NbO2.5, TiO2-ZrO2), LaYO3, nano-structured metal
films and porous electrodes. (19 pages)
