Linear sp carbon nanostructures are gathering interest for the physical properties of one-dimensional systems. At present, the main obstacle to the synthesis and study of these systems is their instability. Here the authors present a simple method to obtain a solid system where linear sp chains (i.e., polyynes) in a silver nanoparticle assembly display a long term stability at ambient conditions. The presence and the behavior of linear carbon are investigated by surface enhanced Raman… 

A molecular quantum wire of linear carbon chains encapsulated within single-walled carbon nanotube (Cn@SWNT)

Pure sp-hybridized linear carbon chains possess unique physical properties of one-dimensional (1D) system. However, linear carbon chains are highly unstable and require to be stabilized within a

The rich interplay between the structural, vibrational, and electronic properties focusing on recent advances and the future perspectives of carbon-atom wires and novel hybrid sp-sp(2)-carbon architectures are discussed.

Aggregation of Polyynes on Metal Nanoparticles

We investigated the interaction between polyynes (linear carbon chains) and various metal nanoparticles (Ag, Au, and Cu) to provide insight into the optical properties of metal-polyynes systems

Formation of linear carbon chains during the initial stage of nanostructured carbon film growth

The initial stage of nanostructured carbon film growth is investigated by molecular dynamics simulations. The carbon film exhibits amorphous structures with linear chains and cyclic rings on the

Raman spectroscopy as a tool to investigate the structure and electronic properties of carbon-atom wires

This short review of carbon-atom wires presents the main CAW synthesis techniques and stabilization strategies and discusses the current status of the understanding of their structural, electronic and vibrational properties with particular attention to how these properties are related to one another.

In situ synthesis of polyynes in a polymer matrix via pulsed laser ablation in a liquid

Polyynes are finite chains formed by sp-hybridized carbon atoms with alternating single and triple bonds and display intriguing electronic and optical properties. Pulsed laser ablation in liquid



Carbon nanowire made of a long linear carbon chain inserted inside a multiwalled carbon nanotube.

A new type of one-dimensional carbon structure, carbon nanowires (CNWs), was discovered in the cathode deposits prepared by hydrogen arc discharge evaporation of carbon rods, and has potential applications in nanoelectronics, nanomechanics, and nanomaterials.

Chemical and thermal stability of carbyne-like structures in cluster-assembled carbon films

Nanostructured carbon films consisting of sp chains (polyynes and polycumulenes) embedded in an sp 2 matrix are grown using supersonic carbon cluster beam deposition in ultrahigh vacuum at room

Cluster-beam deposition and in situ characterization of carbyne-rich carbon films.

Reductive Preparation of Carbyne with High Yield. An in Situ Raman Scattering Study

Electrochemical reductive carbonization of poly(tetrafluoroethylene) with alkali metal (Li, Na, K) amalgams leads to a polymeric carbon with a partly carbynoid structure. Raman spectra measured in

Ab-initio electron transport calculations of carbon based string structures.

First-principles calculations show that monatomic strings of carbon have high cohesive energy and axial strength, and exhibit stability even at high temperatures, and the double covalent bonding of carbon atoms underlies their unusual chemical, mechanical, and transport properties.
