Efficient delivery of growth factors from carrier biomaterials depends critically on the release kinetics of the proteins that constitute the carrier. Immobilizing growth factors to calcium phosphate ceramics has been attempted by direct adsorption and usually resulted in a rapid and passive release of the superficially adherent proteins. The insufficient retention of growth factors limited the...
Nickel-doped Zinc Oxide (Zn(1-x)Ni(x)O) nanoparticles have been synthesized by the chemical coprecipitation method. The structure and characteristic of Ni doped ZnO ware analyzed X-ray diffraction (XRD) patterns. Crystallite sizes lattice strain all samples were calculated using Scherrer’s formula, Uniform Deformation Model (UDM) Halder-Wagner (H-W) analysis confirmed hexagonal cubic Ni-doped n...
Antimosy-doped tin oxide (ATO) particles were prepared via chemical coprecipitation and reverse emulsion. The size and size distribution of ATO particles were obviously decreased via reverse microemulsion method. At the relatively high yield the ATO particles were nearly spherical in shape, meanwhile the crystalline structure and excellent conductivity were reserved, which could satisfy the req...
hazelnuts are usually propagated by suckers or layering. however, other methods of propagation have been tested with variable results. grafting is a method that has a few advantages such as fast multiplication rate, earlier fruiting and reducing sucker removal cost on specific rootstocks. unfortunately, grafting is difficult due to slow formation of callus in hazelnuts. here, we report the hypo...
