Printable and High Performance MnO2-based Energy Storage Devices

Qian J., Lau S.P., The Hong Kong Polytechnic University, HK

Printable electronics is of great interest in the areas ranging from thin film transistors (TFTs), energy storage devices, solar cells to micro electro-mechanical systems (MEMS). To date, preparations of various inks composed of semiconductors, biological [...]

Electronic properties control of single-walled carbon nanotube using spontaneous redox process of MnO4- and carbon nanotube

Shin D.-W., Lee J-H., Yoo J.-B., Sungkyunkwan University, KR

We investigated the effectiveness of electronic properties with single-walled carbon nanotube through spontaneous redox-reaction between the metal oxide ion such as MnO4- and carbon nanotube. The SWCNTs synthesized by the arc discharge method were used. [...]

A facile low-temperature route for preparing monodisperse Mn3O4 nanopolyhedrons from amorphous MnO2 nanoparticles

Ma J., Zhang S., Liu W., Zhao Y., University of Shanghai for Sci& Tech., CN

In the paper, we firstly show a facile hydrothermal route for synthesizing monodisperse Mn3O4 nanopolyhedrons directly used new-made amorphous MnO2 nanoparticle with its mother solution as precursors. The hydrothermal process was performed at 160 ºC [...]
