Flux Pinning Force

ABSTRACTEpitaxial Ba2YCu3O7-δ (BYCO) films grown by the ex situ BaF2 process are comparable to single crystals both in crystalline integrity (RBS/ion channeling χmin < 3%) and the value and temperature dependence of the critical current (Jc) in an applied magnetic field in the BYCO (001) direction of Ha = 0.9T. With the appropriate dose of either 2 MeV H+ or 135Xe+, we are able to enhance Jc by a factor of 2 in H = 0.9T with little effect on Tc. The ability to change Jc by such a large factor in these films is a prerequisite for isolation and study of the induced defects and study their properties.

Biomaterial Surfaces

Ion beam irradiation of solid surfaces may result in the self-organized formation of well-defined topographic nanopatterns. Depending on the irradiation conditions and the material properties, isotropic or anisotropic patterns of differently shaped features may be obtained. Most intriguingly, the periodicities of these patterns can be adjusted in the range between less than twenty and several hundred nanometers, which covers the dimensions of many cellular and extracellular features. However, even though ion beam nanopatterning has been studied for several decades and is nowadays widely employed in the fabrication of functional surfaces, it has found its way into the biomaterials field only recently. This review provides a brief overview of the basics of ion beam nanopatterning, emphasizes aspects of particular relevance for biomaterials applications, and summarizes a number of recent studies that investigated the effects of such nanopatterned surfaces on the adsorption of biomolecules and the response of adhering cells. Finally, promising future directions and potential translational challenges are identified.
