Cyclooctatetraene‐Embedded Carbon Nanorings

Angewandte Chemie International Edition
Abstract With the prosperity of the development of carbon nanorings, certain topologically or functionally unique units‐embedded carbon nanorings have sprung up in the past decade. Herein, we report the facile and efficient synthesis of three cyclooctatetraene‐embedded carbon nanorings ( COTCNR

Top‐Up Fabrication of Gold Nanorings

Chemistry – An Asian Journal, 2014
AbstractA 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, 2010
We 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

Fabrication of Multiple Concentric Nanoring Structures

Nano Letters, 2009
We present the fabrication of GaAs/AlGaAs Multiple (from three to five) concentric nanoring structures by an innovative growth method based on droplet epitaxy and characterized by short time As supply to the Ga droplets at different substrate temperatures.

Computational Generation of RNA Nanorings

2017
A 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, 2004
Remarkable 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.
