In Vitro Assessment of Nano-Cerium Oxide (nCeO2) and Nano-Ferric Oxide (nFe2O3) on Fibrogenic and Carcinogenic Potential

Wang L., Davidson D., Stueckle T., Derk R., Chen M., Sotiriou G.A., Demokritou P., Luanpitpong S., Ma J., Mercer R.R., Castranova V., Rojanasakul Y., National Institute for Occupational Safety and Health, US

Goal of the present study is to investigate the specific cellular responses to nCeO2 and nFe2O3 in various lung cell types and develop an in vitro chronic exposure model to predict the potential fibrogenic and [...]

A new strategy of using unstable offshore wind power by combination with pumped storage generation with reversible pump turbine

Zhai Y., Ma J., Mitobe M., Uehara S., Gon S., Sugawara A., Niigata University, JP

The cost of wind energy resources are low and it is abundant, with a characteristic of the energy saving and eco effect. But if large-scale wind power be merged into the power network directly, the [...]

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 [...]

The influences of nanoscale titanium dioxide particle size and crystal structure on light absorbance

Zou M., Yang F., Ma J., Chen Y., Cao L., Liu F., Chinese Academy of Inspection and Quarantine, CN

Nanoscale titanium dioxide is an important physical sun-block material and is widely used in sunscreen. In our test, the influences of the particle size and crystal structure on light absorbance were examined. The experiment shows [...]

Compact Capacitance Model of LDMOS for Circuit Simulation

Ma J., Ma Y., Chen P., Liang H., Ma J., Ma Y., Jeng M-C, Liu Z., Cadence Design Systems, Inc., US

Capacitance modeling in LDMOS is much more complicated than that in bulk MOSFET’s due to the fact of non-uniform lateral channel doping, the extended gate drain overlap region and its interaction with channel charges. Measurements [...]

Layered Oxide Polymer Nanocomposites: Synthesis, Characterization, and Strategies for Achieving Enhanced Barrier Property

Hansen T.J., Barber P., Ma J., Ploehn H.J., zur Loye H.-C., University of South Carolina, US

Our research goal is to enhance the gas barrier of polymer nanocomposites using exfoliated layered materials. We have synthesized various layered oxides, ranging from layered polysilicates to perovskites, and explored novel modification techniques. Polymer films [...]
