A facile block copolymer inclusion technique for large scale monodisperse hexagonal arrays of superparamagnetic iron oxides nanodots

Ghoshal T., Maity T., Godsell J.F., Roy S., Morris M.A., University College Cork, IE

We demonstrate a simple and cost-effective route, based around block copolymer patterning, to create dense arrays of highly ordered iron oxide nanodots at substrate surface. The methodology creates hexagonally arranged features via a process of [...]

Lattice Constant Dependence on Particle Size for Bulk and Doped Ceria prepared from a Citrate Sol-Gel

Morris M.A., Morris V.N., Farrell R.A., Sexton A.M., Morris M.A., Morris V.N., Analog Devices, Dimensional Solids Group, UCC, IE

High surface area ceria nanoparticles have been prepared using a citrate sol-gel precipitation method. Changes to the particle size have been made by calcining the ceria powders at different temperatures, and X-ray methods used to [...]

Growth of Carbon Nano-Structures in Ceramic Materials

Kufazvinei C., Leahy R.W., Lipson S.M., Blau W.J., Dillon F.C., Spalding T.R., Morris M.A., Holmes J.D., Allan G., Patterson J., Trinity College Dublin, IE

The investigation aims at growing carbon nanotubes of controlled diameter from inside pores of ceramic materials. The resulting carbon nanotubes will then be used in electrons as thermally conductive substrates in die mountings.

Conductive Films of Ordered High-Density Nanowire Arrays

Kulkarni J.S., Daly B., Ziegler K.J., Crowley T., Erts D., Polyakov B., Morris M.A., Holmes J.D., University College Cork, IE

We have prepared high-density, ordered arrays of semiconductor nanowires within the pores of mesoporous thin films (MTFs) and anodized aluminum oxide (AAO) matrices using a supercritical fluid solution-phase inclusion technique. Conductive atomic force microscopy (C-AFM) [...]
