Electrochemical behavior and structural changes of V2O5 xerogel
Thin films of V2O5 xerogel were characterized by several in-situ techniques for different amount of intercalated Li+. Changes in the V2O5 mechanical properties were analyzed by electroacoustic impedance data, indicating that lithium intercalation does ...

Reverse saturable absorption in solid xerogel matrices
International audienceAluminophthalocyanine (APC) and fullerene carbon 60 (C,) have been studied encaged in different silica matrices. The reverse saturable absorption properties of these doped xerogels have been compared to those of reference solutions ...

Phase transformations in xerogels of mullite composition [PDF]
Monophasic and diphasic xerogels have been prepared as precursors for mullite (3Al2O3-2SiO2). Monophasic xerogel was synthesized from tetraethyl orthosilicate and aluminum nitrate nanohydrate and the diphasic xerogel from colloidal suspension of silica ...

Development of an osteoblast/osteoclast co-culture derived by human bone marrow stromal cells and human monocytes for biomaterials testing [PDF]
The communication of bone-forming osteoblasts and bone-resorbing osteoclasts is a fundamental requirement for balanced bone remodelling. For biomaterial research, development of in vitro models is necessary to investigate this communication.
