Research Article 2017, 8(12), 1161-1165 Advanced Materials Letters A Monte Carlo arithmetic method is utilized to investigate the Peierls transition in the linear and circular carbon nanowire respectively. The carbon nanowires interacting with the 6 nearest neighbors in hexagonal structure are spaced by 0.3 nm. Despite the Peierls transition of the linear carbon nanowires is unaffected by the Van der Waal’s force, we discovered that the Peierls transition temperature of the isolated curved nanowire is…"C.H.Wong, J.

Kroto published a study with colleagues at Arizona State University that ends thusly: “The bottom line is that carbyne, the linear carbon…"Matt Davenport Harry Kroto’s last words on carbyne"
Carbyne, the third allotrope of carbon with alternating single and triple bonds, consists of sp-hybridized carbon atoms. Theoretically, with two degenerate π-electron bands in one monomer, carbyne exhibits stronger nonlinear optical responses than graphene and it is acknowledged as a superior nonlinear optical material with just one π-electron band. Very recently, carbyne has been synthesized in the laboratory. Here, we demonstrate the giant nonlinear optical responses of carbyne. By employing the Z-scan technique using a…"C. R. Ma, J.

PUBLISHED ONLINE: 19 SEPTEMBER 2010 | DOI: 10.1038/NCHEM.828 Carbyne is an allotrope of carbon composed of sp-hybridized carbon atoms. Although its formation in the laboratory is suggested, no well-defined sample is described. Interest in carbyne and its potential properties remains intense because of, at least in part, technological breakthroughs offered by other carbon allotropes, such as fullerenes, carbon nanotubes and graphene. Here, we describe the synthesis of a series of conjugated polyynes as models for…"Wesley A. Chalifoux and Rik R. Tykwinski Synthesis of polyynes to model the sp-carbon allotrope carbyne"
Представлен обзор работ по синтезу, экспериментальному и теоретическому исследованию новых аллотропных форм углерода, отличных от ранее известных (алмаза, графита, фуллеренов и нанотрубок) новым типом химических связей между атомами углерода. Это – нанофазы углерода, устойчивые в наноразмерной области: две формы линейно цепочечного углерода – пленки и кристаллы, различающиеся по структуре, и углерод с ГЦК-структурой. Материалы, реализованные на их основе, обладают уникальными свойствами и находят разнообразные применения в различных областях науки, техники и медицины. Ключевые слова: метастабильные…"Бабаев В.Г., Гусева М.Б., Хвостов В.В., Савченко Н.Ф., Новиков Н.Д., Александров А.Ф. Синтез новых наноформ углерода"
Carbon Vol 30. No. 2.pp.2 13-211. 1992 Abstract The paper reports on the study of oriented carbyne layers prepared using three different techniques: (a) chemical carbonization of a polvfvinylidenc fluoride) film, (b) ion sputtering of graphite, and (c) condensation of carbon vapor produced by an electrical arc. The crystalline structure of both oriented carbyne films and single crystal microinclusions were studied by electron diffraction. The electronic structure of the carbyne was studied by Auger electron…"Yu. P. Kudryavtsev, S. E. Evsyukov, V. G. Babaev, M. B. Guseva, V. V. Khvostov, L. M. Krechko Oriented carbyne layers"
Russian Chemical Bulletin, Vol. 42, No. 3, March, 1993 The history of the discovery of carbyne, the chemical and physical methods used to obtain it, the analysis of its structure, and some of its properties are briefly considered. The prospects for its practical applications are discussed. The existence of carbyne opens up prospects for the creation of unique materials on its basis. These are, first of all, one-dimensional semiconducting materials, whose many extremely interesting properties…"Yu. P. Kudryavtsev, S. E. Evsyukov, B. Guseva, V. G. Babaev, V.V.

During past years one-dimensional carbon allotropes containing sp1 bonds, both individual chains and carbyne-like crystals held by Van der Waals forces, were attracting much interest. One of the recent developments in the field is the ion-assisted condensation of carbyne-like sp1 chains, in-plane ordered in a hexagonal structure with nearly 5 angstroms interchain distance – the so called “tetracarbon”. In present work the obtained experimental Raman spectra of the 200 – 4000 angstrom films of…"Evgeny Buntov, Anatoly Zatsepin, Malvina Guseva and Yuri Ponosov Structure and vibrational properties of collinearly ordered carbon chains"
Mar. 2005 Abstract The existence, stability and synthesis of carbyne are reviewed and discussed briefly. The stability is related to the type of carbyne, atmosphere and environment. It is proposed that carbyne can be stabilized by some potential techniques such as end-lapping oligoynes, carbyne intercalation compounds, etc. Conclusions The existence of carbyne in nature were reviewed briefly and discussed in the present paper. Carbyne was found both in interstellar medium and earth and detected also…"CHUAN Xiu-yun, WANG Tong-kuan, Jean-Baptiste DONNET Stability and existence of carbyne with carbon chains"
