Low Temperature Plasma Surface Treatment of Catalytic Material

Miley G.H., Srivastava S., Kim K-J, Chen G., Uiversity of Illinois and NPL Associates, US

We are developing a low temperature plasma treatment to modify the surfaces of various heterogeneous catalytic materials. The plasma modification has been shown to radically change the surface morphology of various catalytic materials including nickel, [...]

Catalytic Performance Enhancement by Low Temperature Plasma Treatment

Miley G.H., Srivastava S.N., Chen G., UiUC/NPL Associates, US

Polymer Electrolyte Membrane (PEM) fuel cell electrocatalysts are composed of noble metals (e.g. platinum), which are scarce and expensive. A simple plasma-surface modification method is described to increase the performance of PEM fuel cell catalytic [...]

Surface tailoring of carbon fabric reinforced PES composites with micro and nano PTFE fillers

Sharma M., Bijwe J., Indian Institute of Technology Delhi, IN

Carbon fabric reinforced polymers (CFRPs) are being increasingly used as advanced composites for structural materials applications, especially in aircraft industry because of very high specific strength and modulus apart from their higher thermal conductivity, corrosion [...]

Sample Concentration by Asymmetry EOF flow in Micro/Nano Channels with O2/H2O Plasma Treated Channel Surfaces

Wu R-Q, Tseng F-G, Yang C-S, Cheing C-C, National Tsing Hua University, TW

In this study, we propose a new technique to concentrate sample effectively, which employs different surface treatment on the top and bottom of micro/nano channels. This treatment carries out different zeta-potentials on the opposite walls [...]
