Metallocene-Filled Single-Walled Carbon Nanotube Hybrids

Abstract

In this paper, the growth mechanism, structure, growth processes, growth kinetics, and optical, vibronic and electronic properties of metallocene-filled single-walled carbon nanotubes (SWCNTs) are considered. A description of the procedures used to fill the nanotubes is provided. An investigation of doping effects on metallicity-mixed SWCNTs filled with metallocenes by Raman spectroscopy, near edge X-ray absorption fine structure spectroscopy, photoemission spectroscopy, and optical absorption spectroscopy is described. The studies of doping effects on metallicity-sorted SWCNTs filled with metallocenes are discussed. Doping effects in metallicity-mixed and sorted SWCNTs upon the chemical transformation of encapsulated molecules are analyzed. A discussion of the modification of the electronic properties of filled SWCNTs is presented. Applications of metallocene-filled SWCNTs in electrochemistry, thermoelectric power generation, chemical sensors, and magnetic recording are discussed.

Electroconductive Collagen‐Carbon Nanodots Nanocomposite Elicits Neurite Outgrowth, Supports Neurogenic Differentiation and Accelerates Electrophysiological Maturation of Neural Progenitor Spheroids

“…Despite the considerable efforts to characterize the potential neurotoxicity of carbon‐based nanomaterials, [ 42,72,73 ] the results reported in the literature remain controversial, likely due to interstudy variations in size, physicochemical properties, and concentration. Here, to evaluate the cytocompatibility of both collagen‐immobilized and suspended GlyCNDs with iPSC‐derived NP spheroids, we carried out a colorimetric lactate dehydrogenase (LDH) assay complemented with propidium iodide (PI) live staining of dead cells.…”

Nanostructures as the Substrate for Single-Molecule Magnet Deposition

“…On the other hand, metallocene dysprosium SIMs have, in recent years, enabled the achievement of blocking temperatures surpassing the ’magical’ liquid-nitrogen level. Consequently, it would be compelling to couple them with a preferred type of nanostructure, especially considering that studies have already demonstrated such coupling in the case of metallocene-SWCNT hybrids [ 228 ]. Here, the latest achievements by Komeda and co-workers, concerning the employment of superconducting NbSe substrates for TbPc molecules, are also worth mentioning, although the authors did not include information about the thickness of the used NbSe layer, which made it hard for us to consider it a nanostructure [ 229 , 230 ].…”

On the Magnetization and Entanglement Plateaus in One-Dimensional Confined Molecular Magnets

“…Figure 2d displays a schematic of the Ni(acac) 2 -filled SWCNTs (single-wall carbon nanotubes) as the SMMs are being wrapped. To model the precise arrangement of the SMMs inside the SWCNTs would likely require a mixture of experimental, ab initio, and/or Hamiltonian techniques; however, there have been only a limited amount of approaches to form ordered structures inside the nanotube channels [26,42], and recent experiments with magnetic molecules still lack enough insight on this particular inquiry [44]. In this work, we explore three of the highest-symmetry configurations with respect to the axis of the tube and the planes perpendicular to it, which could be used to screen and/or interpret other energetically stabilized molecular arrangements.…”
