Re-dispersible ZrO2 powders for transparent high RI nanocomposite

Wang S-H., Sun Y.S., Chiang A.S.T., National Central University, TW

Previous products of nano-ZrO2 usually come in the form of dispersed sol. When they are to be used in organic/inorganic composite, the solvent accompanied may not be compatible with the target polymer system. We have [...]

Evaluation of Uncertainty in Nanoparticle Size Measurement by Differential Mobility Analysis

Lin C-M, Yu T.-C., Lai S.H., Ho H.C., Weng H.F., Wang S-H., Chen C-J., Center for Measurement Standards, Industrial Technology Research Institute, TW

This paper presents the measurement results and the uncertainty analysis for four batches of polystyrene latex (PSL) spheres with nominal sizes of 20 nm, 100 nm, 300 nm and 500 nm using the measurement system [...]

Pneumatic Regulation of Bi-Directional Fluid Flow in Microchannels

Wan Y-M., Wang S-H., Yao N-K., Chen C., Hung L-Y., Wang S-H., ITRI, TW

This paper presents a modeling of airflow inside micro-tunnel for fluid pumping. By utilizing unidirectional air servo system, fluid flow can be regulated within microchannels. The operation of servo system is controlled with multiple nozzles. [...]
