Carbon nanowires made by the insertion-and-fusion method toward carbon–hydrogen nanoelectronics

Autor: Fu Liu, Qingqing Wang, Yuchao Tang, Wan Du, Weiwei Chang, Zewei Fu, Xinluo Zhao, Yi Liu

Publikováno v: Nanoscale. 15:6143-6155

Carbon nanowires can be made via the insertion-and-fusion of short carbon chains inside carbon nanotubes, and carry H adatoms that can tune the electronic and magnetic properties of carbon chains upon the varied H positions in C–H nanoelectronics.

Carbon-rich superhard ruthenium carbides from first-principles

Autor: Shipeng Zhao, Yali Yang, Jian Lu, Wei Wu, Sheng Sun, Xi Li, Xinluo Zhao, Shixun Cao, Jincang Zhang, Wei Ren

Publikováno v: Materials & Design, Vol 117, Iss , Pp 353-362 (2017)

Compounds formed by transition metals and light elements have attracted increasing attention owing to superior functionalities. Here, high throughput first-principles calculations are employed to investigate the crystal structures and physical proper

Smallest carbon nanowires made easy: Long linear carbon chains confined inside single-walled carbon nanotubes

Autor: Weiwei Chang, Fu Liu, Liang Fang, Yifan Liu, Tianxiang Zhu, Yi Liu, Qianqian Li, Xinluo Zhao

Publikováno v: Carbon. 183:571-577

The carbon nanowires are defined as long linear carbon chains (LLCCs) or carbynes confined inside carbon nanotubes (CNTs). LLCCs were synthesized previously inside multi-walled CNTs (LLCCs@MWCNTs) and double-walled CNTs (LLCCs@DWCNTs). In this work,

Purification of polyynes via carbides

Autor: Liang Fang, Yi Liu, Tianxiang Zhu, Weiwei Chang, Xinluo Zhao

Publikováno v: Carbon. 179:28-32

The synthesis of carbyne has remained an elusive goal for decades. One of the significant reasons is that high-purity and high-concentration hydrogen end-capped polyynes (C2nH2) as the most important model molecule and precursors for carbyne have bee

Significant enhancement of metal heat dissipation from mechanically exfoliated graphene nanosheets through thermal radiation effect

Autor: Junxiong Hu, Jianbao Xu, Chao Zhu, Qi Li, Zaka Ullah, Fengkui Liu, Weiwei Li, Yufen Guo, Xinluo Zhao, Liwei Liu

Publikováno v: AIP Advances, Vol 7, Iss 5, Pp 055315-055315-7 (2017)

We demonstrate a facile approach to significantly enhance the heat dissipation potential of conventional aluminum (Al) heat sinks by mechanically coating graphene nanosheets. For Al and graphene-coated Al heat sinks, the change in temperature with ch

Nickel-catalyzed asymmetric reductive arylation of α-chlorosulfones with aryl halides

Autor: Hegui Gong, Chuanhu Lei, Guobin Ma, Xinluo Zhao, Deli Sun

Publikováno v: Chemical Science

We report an asymmetric Ni-catalyzed reductive cross-coupling of aryl/heteroaryl halides with racemic α-chlorosulfones to afford enantioenriched sulfones. The reaction tolerates a variety of functional groups under mild reaction conditions, which co

High-yield growth of multi-walled carbon nanowires by magnetic field controlled arc technique

Autor: Yifan Zhang, Takahiro Maruyama, Weiwei Chang, Yi Liu, Xinluo Zhao

Publikováno v: Carbon. 158:672-680

Multi-walled Carbon nanowires (MWCNWs) made of long linear carbon chains inside multi-walled carbon nanotubes (LLCC@MWCNTs) have been successfully prepared by magnetic field enhanced hydrogen arc discharge. It has been found that introducing a static
