Electrodes are one of essential components in electro-chemical energy conversion devices used for energy storage and generation. In this presentation, micro- and nano-engineered electrodes made of metallic backbones will be introduced. The electrode comprises a [...]

Molecular sieve membranes made in thin sheet form

Liu W., Molecule Works Inc., US

A new molecular sieve membrane technology will be introduced in this presentation from fundamental designs to performance characteristics. Molecular sieve materials are well known for their molecular sieving functions, i.e., distinguishing individual molecules based on [...]

Polarization insensitive and wide-angle plasmonically induced transparency by planar metamaterial

Chen S., Cheng H., Duan X., Gu C., Li J., Liu W., Tian J., Yang H., Nankai University, CN

We present the design, characterization and experimental demonstration of a polarization insensitive and wide-angle plasmonically induced transparency (PIT) planar metamaterial (MM) in the near infrared regime. A four-level plasmonic model is proposed to explain and [...]

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

Liu W., Ma J., Zhang S., 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 [...]
