    摘要： The invention relates generally to generation of biomimetic scaffolds for bone tissue engineering and, more particularly, to multi-level lamellar structures having rotated or alternated plywood designs to mimic natural bone tissue. The invention also includes methods of preparing and applying the scaffolds to treat bone tissue defects. The biomimetic scaffold includes a lamellar structure having multiple lamellae and each lamella has a plurality of layers stacked parallel to one another. The lamellae and/or the plurality of layers is rotated at varying angles based on the design parameters from specific tissue structural imaging data of natural bone tissue, to achieve an overall trend in orientation to mimic the rotated lamellar plywood structure of the naturally occurring bone tissue.

    摘要： The invention provides electro-catalyst compositions for an anode electrode of a proton exchange membrane-based water electrolysis system. The compositions include a noble metal component selected from the group consisting of iridium oxide, ruthenium oxide, rhenium oxide and mixtures thereof, and a non-noble metal component selected from the group consisting of tantalum oxide, tin oxide, niobium oxide, titanium oxide, tungsten oxide, molybdenum oxide, yttrium oxide, scandium oxide, cooper oxide, zirconium oxide, nickel oxide and mixtures thereof. Further, the non-noble metal component can include a dopant. The dopant can be at least one element selected from Groups III, V, VI and VII of the Periodic Table. The compositions can be prepared using a surfactant approach or a sol gel approach. Further, the compositions are prepared using noble metal and non-noble metal precursors. Furthermore, a thin film containing the compositions can be deposited onto a substrate to form the anode electrode.
