Synthesis and characterization of magnetic nanorings for neuronal stimulation
Magnetic nanorings (MNRs) are anisotropic nanomaterials that can support a magnetic vortex state, which can yield both colloidal stability and large hysteretic power losses when exposed to an alternating magnetic field (AMF). Coupled with the biocompatibility of polymer surface coatings, MNRs have …

Brillouin scattering investigation of nanomagnetic structures
… arrays of vertical ferromagnetic nanowires and nanorings, which show great promise as high-density magnetic storage and sensor devices. Three closely related projects are reported: (1) observation of bulk magnon quantization in Ni nanowires: bulk spin wave quantization has been observed, and the …

Quantization of spin waves in ferromagnetic Ni80Fe20 nanoring
Regular arrays of oval-shaped permalloy nanorings have been fabricated using deep ultraviolet lithography and their spin dynamicsmeasured by Brillouin light scattering with the magnetic field applied along long (easy) axes of the rings. The dispersionless behavior of the spin wave modes observed …

Understanding nanomagnetism from all angles: Developments in magnetic electron tomography
… in next-generation computers), vortex states in nanorings (which are being developed to treat cancer), and long-term stability in paleomagnetic samples (which allow researchers to study the formation of planetary bodies in the solar system). Many of these behaviours are intrinsically 3D in …

Characterizing Engineered Nanomaterials: From Environmental, Health and Safety Research to the Development of Shaped Nanosphere Lithography for Metamaterials
… region. Finally, in the course of developing the nanorings, etch conditions were developed to deposit large area arrays of polystyrene nanodoughnuts with diameters from 128 to 242 nm. These non-conductive structures provide an ideal template for further attachment of magnetic of optically emissive …

Electrochemical fabrication of AuCo nanostructures
… hollow nano-bamboo structure and ordered nanorings with various aspect ratios were developed through the electrochemical etching of Au/CoAu nanotubes in a similar way. To the best of the author’s knowledge, this has not been done before.

Computational Modeling of Superconductivity from the Set of Time-Dependent Ginzburg-Landau Equations for Advancements in Theory and Applications
… The other 3-D model showed how superconducting nanorings, due to their size and closest to the critical temperature, violate conservation of magnetic flux when of dimensional size of the order of λ<sub>L</sub>.</p>

Toward therapeutic nanoassemblies: the design and modeling of protein-protein interactions.
Unraveling the nanoscale processes of biological pathways via the testing, replication, and visualization of the underlying mechanisms remains a persistent challenge in the study of these critical life-governing systems. Recent advances in the field of chemically induced dimerization have unlocked …
