From Biogas To Syngas Over Ni Incorporated Ca and Mg Based Hydrotalcite-Like Catalysts

Yasyerli S., Topaloglu G., Dogu G., Gazi University, TR

Catalytic transformation of methane-carbon dioxide mixture, produced through anaerobic digestion of organic waste, to syngas is a promising route for the production of chemicals and fuels from biogas. Dry reforming of methane is expected to [...]

Photoconductivity of GaN Nanowires

Teker K., Siemann A., Istanbul Sehir University, TR

Gallium nitride nanostructures continue to attract great interest due to their applications in optoelectronic devices (UV photodetectors, and light-emitting devices), high-power/high temperature electronics, nanosensing, and piezoelectric nanogenerators. This paper presents a systematic photoconductivity investigation of [...]

Electrospun Nanofibers of Conductive Polymer Composites
