Top‐Up Fabrication of Gold Nanorings
Chemistry – An Asian Journal, 2014AbstractA simple method for the fabrication of gold nanorings with reliable material composition and reproducible morphology that relies on a combination of top‐down and bottom‐up techniques is presented. Here, lithographically defined hole arrays are used as templates for the deposition of gold nanoparticles.

Quantum tunneling through graphene nanorings
Nanotechnology, 2010We investigate theoretically quantum transport through graphene nanorings in the presence of a perpendicular magnetic field. Our theoretical results demonstrate that the graphene nanorings behave like a resonant tunneling device, contrary to the Aharonov-Bohm oscillations found in conventional semiconductor rings. The resonant tunneling can be tuned by

Computational Generation of RNA Nanorings
2017A variety of designed RNA ring structures (ranging from triangles to hexagonal rings) have been reported in the scientific literature. Designing self-assembling RNA ring structures from structural motifs is, however, a nontrivial problem as there are many combinations of motifs and linking helices.

Cobalt-Based Superparamagnetic Nanorings
Nano Letters, 2004Remarkable optical and magnetic properties were observed in a Co-thiol-polymer composite. The Co and the thiol ligand used to passivate the Co surface, instead of generating isolated nanoparticles, grow into nanorings with a radius around 2 nm. These structures consist of small clusters of metallic Co connected by alkylthiol chains.

Bundled Silicon Nitride Nanorings
Crystal Growth & Design, 2008Bundled nanorings composed of several self-coiled nanowires are synthesized by catalyst-assisted pyrolysis of a polymeric precursor. Microstructural observation reveals that the nanowires have a bilayer structure consisting of a thin single-crystal Si3N4 layer and a thick amorphous layer.
