Effective role of CaO/P 2 O 5 ratio on SiO 2 -CaO-P 2 O 5 glass system

Response of human bone marrow stromal cells to a resorbable P(2)O(5)-SiO(2)-CaO-MgO-Na(2)O-K(2)O phosphate glass ceramic for tissue engineering applications.

This work focuses on the synthesis and characterization of a novel bioresorbable glass ceramic phosphate-based material (GC-ICEL). More specifically, its solubility in different aqueous media (water, Tris-HCl and acellular simulated body fluid) and the response of human stromal cells cultured on it were investigated. X-ray diffraction analysis showed the presence of two crystalline phases ident...

Branching ratio for the 5 S o 2 - 3 P 2 , 1 inter - system resonance multiplet in P II

The P II inter-system multiplet, 3s3p 3 5

SiO(2)/Ta(2)O(5) core-shell nanowires and nanotubes.

One-dimensional nanostructures such as nanowires, nanobelts, and nanotubes have attracted much attention as a result of their unique properties, which can be applied in the fabrication of biomedical sensors, optoelectronic devices, field-effect transistors, and field-emission devices, for example. In particular, one-dimensional nanostructures of metal oxides such as ZnO, SnO2, [3] a-Fe2O3, [4] ...

Charge Ordering and Optical Transitions of Liv 2 O 5 and Nav 2 O 5

We present the measurements of the polarized optical spectra of NaV2O5 and LiV2O5. In the energy range from 0.5 to 5.5 eV we observe similar peaks in the E ‖ a spectra of NaV2O5 and LiV2O5, which suggests similar electronic structure along the a axis in both materials. On the other hand, we find almost complete suppression of the peaks in σb of LiV2O5 around 1 and 5 eV. We attribute this suppre...
