Significant electrochemical stability of manganese dioxide/polyaniline coaxial nanowires by self-terminated double surfactant polymerization for pseudocapacitor electrode

17-10-2012 | Afriyanti Sumboja; Ce Yao Foo; Jian Yan; Chaoyi Yan; Raju Kumar Gupta; Pooi See Lee, Journal of Materials Chemistry, 2012

Manganese dioxide/polyaniline coaxial nanowire networks are prepared by using double surfactant approach. This approach improves the interaction between the two active materials which has been confirmed by FTIR and XPS measurements, and yields a controllable uniform thin coating of polyaniline on ...

Reduced charge fluctuations in individual SnO2 nanowires by suppressed surface reactions

16-10-2012 | Junghwan Huh; Min-Kyu Joo; Doyoung Jang; Jong-Heun Lee; Gyu Tae Kim, Journal of Materials Chemistry, 2012

The interactions between metal oxide nanowires and molecular species can significantly affect the electrical properties of metal oxide nanowires. A passivation process is needed to stabilize the electrical characteristics, regardless of the environmental changes. Herein, we investigated the ...

Monodispersed ultrathin GdF3 nanowires: oriented attachment, luminescence, and relaxivity for MRI contrast agents

03-10-2012 | Yang Tian; Hong-Yu Yang; Kai Li; Xue Jin, Journal of Materials Chemistry, 2012

A facile solvothermal approach was used to synthesize monodispersed ultrathin GdF3 nanowires via an oriented attachment mechanism. Gadolinium nitrate acted as the Gd source, n-octylamine and oleic acid as capping ligands, and n-octanol as solvent. The phase and morphology of the nanowires were ...

Highly Efficient Visible-Light-Driven Plasmonic Photocatalysts Based on Graphene Oxide Hybridized One-Dimensional Ag/AgCl Heteroarchitectures

05-09-2012 | Mingshan Zhu; Penglei Chen; Minghua Liu, Journal of Materials Chemistry, 2012

In this paper, we report that one-dimensional (1D) Ag/AgCl nanostructures could be facilely fabricated by means of an oxidation-chloridization process, wherein prefabricated 1D Ag nanowires are employed as template. Graphene oxide (GO) hybridized 1D Ag/AgCl nanocomposites, Ag/AgCl/GO, could also ...

One-Step Vapor-Solid Reaction Growth of Sn@C Core-Shell Nanowires as an Anode Material for Li-Ion Batteries

05-09-2012 | Kai-Chieh Hsu; Chia-Erh Liu; Po-Chin Chen; Chi-Young Lee; Hsin-Tien Chiu, Journal of Materials Chemistry, 2012

Sn@C core-shell nanowires (NWs) were synthesized by reacting SnO2 particles with a flowing mixture of C2H2 and Ar gases at elevated temperatures. The overall diameter of the core-shell nanostructure was 100 – 350 nm. The C shell thickness was 30 – 70 nm. The NW length was several micrometers. ...

Induction of the surface plasmon resonance from C-incorporated Au catalyst in Si1−xCx nanowires

22-08-2012 | Woo-Jung Lee; Jin Won Ma; Jung Min Bae; Sang Han Park; Kwang-Sik Jeong; Mann-Ho Cho; Chul Lee; Kyong-Joo Han; Kwun-B ..., Journal of Materials Chemistry, 2012

Si1−xCx nanowires (NWs) were synthesized by varying the ratio of SiH4 and CH3SiH3 gases using a vapor–liquid–solid (VLS) procedure using Au as a catalyst. The growth rate of the Si1−xCx NWs and the change in the wire shape from straight to helical near the Au tip were found to be closely related ...

Nanowires of oligothiophene-functionalized naphthalene diimides: self assembly, morphology, and all-nanowire bulk heterojunction solar cells

16-08-2012 | Guoqiang Ren; Eilaf Ahmed; Samson A. Jenekhe, Journal of Materials Chemistry, 2012

We report the solution-phase self-assembly of nanowires of a series of six oligothiophene-functionalized naphthalene diimides (NDI-nTH and NDI-nT) and their use as electron acceptors in all-nanowire bulk heterojunction organic solar cells. The dimensions and detailed morphology of the nanowires ...
