Synthesis and characterization of Mg2Si/Si nanocomposites prepared from MgH2 and silicon, and their thermoelectric properties

22-11-2012 | Tanghong Yi; Shaoping Chen; Shawn Li; Hao Yang; Sabah Bux; Zhixi Bian; Nebil A. Katcho; Ali Shakouri; Natalio Mingo; ..., Journal of Materials Chemistry, 2012

Silicon (Si) nanoparticles embedded in a Mg2Si matrix (Mg2Si/xSi) have been successfully synthesized at 623 K from MgH2 and Bi containing Si nanoparticle powders. The use of MgH2 in this synthetic route avoids the formation of oxides through the generation of hydrogen and provides a route to ...

Pyrene-directed growth of nanoporous benzimidazole-linked nanofibers and their application to selective CO2 capture and separation

15-11-2012 | Mohammad Gulam Rabbani; Ali Kemal Sekizkardes; Oussama M. El-Kadri; Bilal R. Kaafarani; Hani M. El-Kaderi, Journal of Materials Chemistry, 2012

A pyrene-based benzimidazole-linked polymer (BILP-10) has been synthesized by the co-condensation of 1,3,6,8-tetrakis(4-formylphenyl)pyrene and 1,2,4,5-benzenetetramine tetrahydrochloride in dimethylformamide. The use of pyrene as a molecular building unit leads to the formation of self-assembled ...

Graphene Nanosheets/Titanium Nitride Nanocomposite for High Performance Electrochemical Capacitors without Extra Conductive Agent Addition

10-10-2012 | Pengxian Han; Yanhua Yue; Xiaogang Wang; Wen Ma; Shanmu Dong; Kejun Zhang; Chuanjian Zhang; Guanglei Cui, Journal of Materials Chemistry, 2012

Graphene nanosheets/titanium nitride (G/TiN) nanocomposite has been fabricated through a simple in situ hydrolysis method combined with ammonia annealing. TiN nanoparticles are homogeneously anchored on G, which is beneficial for the formation of porous structure and the enhancement of electrical ...

Au–Cu2S heterodimer formation via oxidization of AuCu alloy nanoparticles and in situ formed copper thiolate

09-10-2012 | Xianguang Ding; Yu Zou; Jiang Jiang, Journal of Materials Chemistry, 2012

The synthesis of hybrid nanostructures has been of great interest to many material scientists, yet simple and facile routes to prepare these structures remain a difficult task with many reaction variables to tune. Herein, we report the synthesis of Au–Cu2S heterodimers from AuCu alloy ...

Transformation of hydrothermally derived nanowire cluster intermediates into CdSiO3 nanobelts

04-10-2012 | C. Manjunatha; B. M. Nagabhushana; H. Nagabhushana; R. P. S. Chakradhar, Journal of Materials Chemistry, 2012

In this communication, we demonstrate that cadmium metasilicate nanobelts could be fabricated via a facile, eco-friendly, low cost hydrothermal treatment in the absence of surfactants and organic additives, followed by calcination. The monoclinic phase formation of the sample is described in ...

UV Induced Formation of Transparent Au-Ag Nanowire Mesh Film for Repairable OLED Devices

26-09-2012 | Tatyana Levi belenkova; Dolev Rimmerman; Elad Mentovich; Hagit Gilon; Netta Hendler; Shachar Richter; Gil Markovich, Journal of Materials Chemistry, 2012

The next generation of optoelectronic devices requires transparent conductive electrodes to be flexible, cheap, and compatible with large scale manufacturing processes. Indium Tin Oxide (ITO) electrodes are often used due to their superior transparency and conductance, however they are brittle, ...

Ferroelectric ceramics with enhanced remnant polarization by ordered coalescence of nano-crystals

26-09-2012 | James Zhijian Shen; Haixue Yan; Daniel Grüner; Lyubov M Belova; Yasuhiro Sakamoto; Jianfeng Hu; Cewen Nan; Thomas Hö ..., Journal of Materials Chemistry, 2012

An exceptional high ferroelectric remnant polarization (Pr) was observed in BaTiO3 ceramics owing to the formation of micron-sized grains possessing nano-scale mosaicity. Such a structural hierarchy was developed via a novel crystal-growth mechanism, namely ordered coalescence of nano-crystals ...

Super-tough conducting carbon nanotube/ultrahigh-molecular-weight polyethylene composites with segregated and double-percolated structure

26-09-2012 | Huan Pang; Ding-Xiang Yan; Yu Bao; Jin-Bing Chen; Chen Chen; Zhong-Ming Li, Journal of Materials Chemistry, 2012

Super-tough conducting carbon nanotube (CNT)/ultrahigh-molecular-weight polyethylene (UHMWPE) composites were prepared by a facile method; a small amount of high-density polyethylene (HDPE) was used as the carrier polymer for the CNTs. A structural examination revealed the formation of unique ...

Studies on the properties and formation mechanism of flexible nanocomposite hydrogels from cellulose nanocrystals and poly(acrylic acid)

25-09-2012 | Jun Yang; Chun-Rui Han; Jiu-Fang Duan; Ming-Guo Ma; Xue-Ming Zhang; Feng Xu; Run-Cang Sun; Xu-Ming Xie, Journal of Materials Chemistry, 2012

A novel series of nanocomposite hydrogels based on cellulose nanocrystals (CNCs) and poly(acrylic acid) (PAA) have been synthesized by in situ free radical polymerization within an aqueous medium. Rheological measurements were applied to monitor the gelation process and results indicated that the ...

Graphene oxide oxidizes stannous to synthesize tin sulfide-graphene nanocomposites with small crystal size for high performance lithium ions batteries

19-09-2012 | Ming Zhang; Danni Lei; Xinzhi Yu; Libao Chen; Qiuhong Li; Yanguo Wang; Taihong Wang; Guozhong Cao, Journal of Materials Chemistry, 2012

This study reports a novel strategy of preparing graphene composites by employing graphene oxide as precursor and oxidizer. It is demonstrated that graphene oxide could oxidize stannous ions to form SnS2 and it is simultaneously reduced to graphene, directly resulting in the formation of ...
