Free-Standing Bimetallic Nanorings and Nanoring Arrays Made by On-Wire Lithography

ACS Nano, 2010
This paper describes a new strategy for synthesizing free-standing bimetallic nanorings and nanoring arrays based upon on-wire lithography and a galvanic replacement reaction. The strategy allows one to tune the diameter, length, and therefore aspect ratio of the nanorings.

Ultrafast Vibrations of Gold Nanorings

Nano Letters, 2011
We investigate the vibrational modes of gold nanorings on a silica substrate with an ultrafast optical technique. By comparison with numerical simulations, we identify several resonances in the gigahertz range associated with axially symmetric deformations of the nanoring and substrate.

Reply to the Correspondence on “How Aromatic Are Molecular Nanorings? The Case of a Six‐Porphyrin Nanoring”**

Angewandte Chemie, 2022
AbstractA recent article by Anderson and co‐workers challenges our conclusions on the aromaticity of the four oxidation states of a butadyine‐linked six‐porphyrin nanoring, based on the experimental 1H‐NMR data and some recent calculations they have performed using the BLYP35 functional.

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.

Synthesis and Characterization of Gold Nanorings

Journal of Nanoscience and Nanotechnology, 2007
In the present work, we report the formation of Au nanorings on quartz substrate by thermal evaporation of Au on quartz and subsequent annealing in certain conditions as a function of metal volume fraction and annealing temperature. Optical extinction cross-sections measurements and atomic force microscopy (AFM) studies have been performed on the as ...
