In this work we have presented a collagen-nanotube composite which has the potential to serve as a scaffold for tissue regeneration. The biofunctionality (shape maintenance) associated with this biocomposite and the observation that the composite induces mineralization of HA crystals in vitro opens a wide range of new possibilities concerning its use for the tissue engineering of bone.

Address correspondence to

Dye-sensitized solar cells (DSCs) based on a photocathode of Ni0.94Pt0.06 films that were prepared by reaction of chemically plated Ni films with H2PtCl6 solution have shown higher conversion effi ciencies than the DSC based on a pure Pt fi lm obtained by conventional thermal decomposition indicating that the as-prepared Ni0.94Pt0.06 films (with a low Pt loading of 5.13 ¦Ìg/cm2) is a promising photocathode material for commercial DSCs.
