Peptides and peptide compositions having osteoinductive activity: 8,815,807

Compositions and kits are provided having a peptide having an amino acid sequence that binds to eukaryotic cells and effects differentiation and support growth of the cells. Peptide-scaffold compositions containing at least one peptide or combinations of peptides are therapeutic agents for stimulating and promoting osteogenic activity and osteoinduction activity for cells. The scaffold is for example apatite, natural cancellous bone, demineralized natural cancellous bone, collagen, calcium phosphate, or hydroxyapatite.

Cyclic metal amides and vapor deposition using them: 8,796,483

Novel cyclic amides containing tin or lead are disclosed. These cyclic amides can be used for atomic layer deposition or chemical vapor deposition of tin or lead as well as their oxides, sulfides, selenides, nitrides, phosphides, carbides, silicides or borides or other compounds. Tin(IV) oxide, SnO.sub.2, films were deposited by reaction of a cyclic tin amide vapor and H.sub.2O.sub.2 or NO.sub.2 as oxygen sources. The films have high purity, smoothness, transparency, electrical conductivity, density, and uniform thickness even inside very narrow holes or trenches. Deposition temperatures are low enough for thermally sensitive substrates such as plastics. Suitable applications of these films include displays, light-emitting diodes, solar cells and gas sensors. Doping SnO.sub.2 with aluminum was used to reduce its conductivity, making material suitable as the active semiconductor layer in electron multipliers or transparent transistors. Deposition using the same tin precursor and H.sub.2S deposited tin monosulfide, SnS, a material suitable for solar cells.
