Bithiophene–Porphyrin Hybrid Nanorings

Chemistry – An Asian Journal, 2010
Covalently linked multiAin arrays have been extensively explored for their numerous applications in molecular devices such as models of photosynthetic systems, sensors, nonlinear optical (NLO) devices, and others. [1–3] The electronic coupling between the constituent porphyrin chromophores is a key parameter that determines the various important ...

Squeezing of magnetic flux in nanorings

Journal of Physics: Condensed Matter, 2012
We study superconducting and non-superconducting nanorings and look for non-classical features of magnetic flux passing through nanorings. We show that the magnetic flux can exhibit purely quantum properties in some peculiar states with quadrature squeezing.

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.

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.

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

SiGe Nanoring Formation

2012 International Silicon-Germanium Technology and Device Meeting (ISTDM), 2012
Based on atomic force microscopy, high-angle annular dark-field scanning transmission electron microscopy, energy dispersive x-ray spectroscopy, and Raman spectroscopy, Ge outdiffusion effects on SiGe quantum dots to form nanorings are studied using the Ultra-High Vacuum Chemical Vapor Deposition.

Structure of carbon nanorings

Computational Materials Science, 2008
Abstract A new family of carbon nanorings with circular centerlines is predicted. The ring structure is parametrized by the chirality of the precursor graphene sheet that is rolled to produce a nanotube and then bent to form a nanoring, and by the number of repeated units defining the ring diameter. The individual atomic positions over rings with zig-
