The structure, composition and magnetic properties of direct-plated fcc Co-Pt-based tubular nanostructures.

Co-Pt-based tubular nanostructures were prepared by direct plating into track-etched polycarbonate templates from a single electrolyte. The high aspect ratio nanotubes can be obtained when performing the deposition at lower voltages. The easy axis of the magnetization was found to be perpendicular to the axis of the tube due to the shape anisotropy of the nanotubes.

Complex magnetic phase in submonolayer Fe stripes on Pt(997).

Experimental results surprisingly reveal a decrease in the total magnetization of two parallel monatomic Fe nanowires in a comparison of the magnetization of a respective single nanowire. On the basis of ab-initio calculations we considered several possible scenarios, which might explain the phenomenon. However, in all cases, the calculated ferromagnetic coupling appears as the energetically most favorable, which hints either a presence of a complex magnetic ordering or an extrinsic origin of the observed property.

Fabrication of CNT-SiC/SiC composites by electrophoretic deposition.

In this study, for the first time, electrophoretic deposition (EPD) was used to deposit (multi-walled) CNTs onto SiC fibres (SiCf) to form an effective CNT interphase layer for SiCf/SiC composites. This deposition was followed by electrophoretic infiltration of the CNT-coated SiC fibre mats with SiC powder to fabricate a new CNT-SiC-fibre-reinforced SiC-matrix (SiCf/SiC) composite for fusion applications.

Quantitative evaluation of structural defect at the atomic-level.

The structure and chemistry of RP faults was performed by applying quantitative high-resolution transmission electron microscopy (HRTEM) and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) analyses. In this study we demonstrated that local planar structural defects can be fully reconstructed and quantified, meaning that the type and position of atoms inside the investigated structure can be precisely determined.

Permanent magnets based on nanostructured intermetallic alloys.

We were invited to contribute a chapter to the Dekker Encyclopaedia, to review our work and the work of other scientists working in the field of nanostructured permanent magnets. This is a very prestigious publication, as the Dekker Encyclopedia of Nanoscience and Nanotechnology takes contributions from leading authorities in the field and is the reference against which all other “nano” references are judged.
