The magnetic polymer ICF targets are fabricated by depositing the Ni-P coats of on the surface of polystyrene microsphere by the electroless plating. The thickness and composition of the coat, and the surface roughness and magnetic property of the magnetic microsphere were examined and analyzed. The results indicated the examined indexes can basicallymeet the requirements of ICF targets.

The attractive action exerted by an array of micro-magnets on a single polystyrene microsphere containing superparamagnetic iron oxidenanoparticles, the microsphere constituting a model for cells functionalised with such nanoparticles, have been studied in air by using magnetic force microscopy. For this purpose, the method of gluing a magnetic microsphere to an AFM tip has been developed. Using this custom-made colloidal probe, the regions of the micro-magnet array that act as magnetic traps for the magnetic microsphere have been localized and the long-range trap-sphere interactions have been recorded, measured and compared with simulations.

Scanning tunneling microscopy (STM) has been used to characterize the surface roughness of nonlinear optical (NLO) polymers. A review of STM of polymer surfaces is included in this volume. The NLO polymers are instrumental in the development of electrooptical waveguide devices, the most fundamental of which is the modulator. The most common modulator design is the Mach Zehnder interferometer, in which the input light is split into two legs and then recombined into a common output within the two dimensional waveguide. A π phase retardation, resulting in total light extinction at the output of the interferometer, can be achieved by changing the refractive index of one leg with respect to the other using the electrooptic effect. For best device performance, it is essential that the NLO polymer exhibit minimal surface roughness in order to reduce light scattering. Scanning tunneling microscopy, with its high lateral and vertical resolution, is capable of quantifying the NLO polymer surface roughness induced by processing. Results are presented below in which STM was used to measure the surface roughness of films produced by spin-coating NLO-active polymers onto silicon substrates.

Cracking Catalysts

For this study we have used a contact mode atomic force microscope (AFM) to study to topography of fluidized cracking catalysts (FCC), before and after contamination with 5% vanadium. We selected the AFM because of its ability to well characterize the surface roughness of materials down to the atomic level. It is believed that the cracking in the FCCs occurs mainly on the catalysts top 10-15 μm suggesting that the surface corrugation could play a key role in the FCCs microactivity properties. To test this hypothesis, we chose vanadium as a contaminate because this metal is capable of irreversibly destroying the FCC crystallinity as well as it microporous structure. In addition, we wanted to examine the extent to which steaming affects the vanadium contaminated FCC. Using the AFM, we measured the surface roughness of FCCs, before and after contamination and after steaming.We obtained our FCC (GRZ-1) from Davison. The FCC is generated so that it contains and estimated 35% rare earth exchaged zeolite Y, 50% kaolin and 15% binder.
