Antibacterial effect of silver nanorings [PDF]
BMC Microbiology, 2020 Background The emergence and expansion of antibiotic resistance makes it necessary to have alternative anti-infective agents, among which silver nanoparticles (AgNPs) display especially interesting properties.

One-Pot Silver Nanoring Synthesis [PDF]
Nanoscale Research Letters, 2009 Silver colloidal nanorings have been synthesized by reducing silver ions with NaBH4 in trisodium citrate buffers. pH increase, by addition of NaOH, was used to speed up reduction reaction. The UV–vis absorption spectra of resulting silver nanorings

Journal of Physics: Condensed Matter, 2007 Ferromagnetic metal rings of nanometre range widths and thicknesses exhibit fundamentally new spin states, switching behaviour and spin dynamics, which can be precisely controlled via geometry, material composition and applied field. Following the discovery of the 'onion state', which mediates the switching to and between vortex states, a range of ...

How Aromatic Are Molecular Nanorings? The Case of a Six‐Porphyrin Nanoring** [PDF]
Angewandte Chemie International Edition, 2021 Abstract Large conjugated rings with persistent currents are novel promising structures in molecular‐scale electronics. A six‐porphyrin nanoring structure that allegedly sustained an aromatic ring current involving 78π electrons was recently synthesized.

ACS Nano, 2008 We have demonstrated that nanostructures, and in particular nanorings incorporating a homodimeric enzyme, can be prepared by chemically induced self-assembly of dihydrofolate reductase (DHFR)-histidine triad nucleotide binding 1 (Hint1) fusion proteins.

Cyclodextrin‐Templated Porphyrin Nanorings [PDF]
Angewandte Chemie International Edition, 2014 Abstractα‐ and β‐Cyclodextrins have been used as scaffolds for the synthesis of six‐ and seven‐legged templates by functionalizing every primary CH2OH with a 4‐pyridyl moiety. Although these templates are flexible, they are very effective for directing the synthesis of macrocyclic porphyrin oligomers consisting of six or seven porphyrin units.

Colloidal lead iodide nanorings [PDF]
Nanoscale, 2018 We present the synthesis and characterization of PbI2 nanorings prepared via a direct colloidal route. The ring structures are obtained by etching as prepared PbI2 nanosheets with trioctylphosphine and possess thicknesses between 20 nm and 85 nm and lateral dimensions of up to 10 μm.

Magnetic Vortex and Hyperthermia Suppression in Multigrain Iron Oxide Nanorings
Applied Sciences, 2020 Single-crystal iron oxide nanorings have been proposed as a promising candidate for magnetic hyperthermia application because of their unique shape-induced vortex-domain structure, which supports good colloidal stability and enhanced magnetic properties.
