Article 3. Hybrid Membrane based on Polymer-doped Phosposilicate and their Characterization

The third article of this issue is published by the Uma Thanganathan from Forschungszentrum, GmbH, Institute of Energy and Climate Research, Germany and Okayama University, Japan. In this research a class of proton-conducting non-fluorinated hybrid composite membranes was produced based on poly(vinylpyrrolidone)-doped tetraethoxysilicate (TEOS) and triammoniumphosphate with and without phosphoricacid. The formation of hybrid composites was verified by various analyses, such as XRD and NMR, and the thermal degradation was determined by thermogravimetric analysis. The proton conductivity was measured using impedance spectroscopy. The results were discussed based on the effects of complex materials on the hybrid composites.

The fifth article of the issue describes by Jing-Ye Juang et al from National Chiao Tung University, Taiwan. University Of California at Los Angeles, USA.

In this work Cu-to-Cu joints of 30 mm in diameter were fabricated using (111)-oriented nanotwinned copper at 300 degrees Celsius for 20 min. The joints possess excellent electrical properties. With a second step annealing at 400 degrees Celsius, the resistance can be reduced due to grain growth across the joint interface. There is 50 percent resistance reduction compared to SnAg solder joints with the same diameter. The electromigration lifetime for Cu-to-Cu joints is at least 750 times longer than solder joints.
