The focus of the present study was to functionalize multilayered DNA-coatings with the osteoinductive factor bone morphogenetic protein 2 (BMP-2) using different loading modalities. The multilayered DNA-coatings were built up from either poly-d-lysine (PDL) or poly(allylamine hydrochloride) (PAH) and DNA using electrostatic self-assembly (ESA). The amounts of BMP-2 loaded into the multilayered ...

For organic and hybrid electronic devices, the physicochemical properties of the contained interfaces play a dominant role. To disentangle the various interactions occurring at such heterointerfaces, we here model a complex, yet prototypical, three-component system consisting of a Cu-phthalocyanine (CuPc) film on a 3,4,9,10-perylene-tetracarboxylic-dianhydride (PTCDA) monolayer adsorbed on Ag(1...

Multilayered film polycarbonate/polystyrene (PC/PS) comprising 257 layers with total thickness 125 lm was made by coextrusion process. The nominal thickness of PC layers was 680 nm, and the nominal thickness of PS layers was 290 nm. Additionally, the control samples of PC and PS with the thickness of 125 lm were coextruded in the same way. There was reasonably good correlation between the PC an...

in this work, the synthesis of porous structure of cadmium oxide with multilayered sheet-like morphology in nano-meter size using adipic acid as soft template by solvothermal/thermal decomposition process is reported. chemical analyses exhibited that the formation of porous sheet-like structure is originated from bidentate coordination mode of adipate units to cd-center. it was found that the c...

FefCo multilayered films with about 3 000 A thick have been deposited by an opposed targets sputtering apparatus. The films with deposition period dlayer above 10 A have layered structure. Their magnetic properties changes significantly with dl, and the film with dlayer around 60 A has the lowest coercive force of about 6 Oe and saturation magnetization about 1 600 emufcc.

The crystal structure and magnetic properties of Fe/AI multilayered films prepared using the ion beam sputtering method have been investigated. The crystallite orientation and magnetism of Fe layers were found to depend significantly on A1 layer thickness. This resutt may be caused by the crystallographic interaction between Fe and A1 layers.

The structural transfqmation from fcc to fct and relevant magnetic properties of initially multilayered Fe/Pt films were studied. When the asdeposited FePt films were annealed at the temperature of 300°C and up, the fct-phase was formed. Rather square hysteresis loops and large coercivities were measured from the annealed films. The films annealed at 300°C retain a layered structure.

Multilayered composite structures and devices have become more popular and are now routinely introduced in advanced systems to reduce size and weight and to improve performance. However, because of the combined complexity of the materials and designs used in these systems, it is a significant challenge to determine the structural integrity and reliability of a specific structure or device using...
