A facile solution-based technique was developed to grow vertically aligned TiO2 nanowires with predominantly anatase phase on arbitrary substrates of stainless steel, glass, silicon wafer and carbon cloth at the low temperature of 80 °C and in an open atmosphere.

It has been previously noted that mixed communities typically produce more power in microbial fuel cells than pure cultures. If true, this has important implications for the design of microbial fuel cells and for studying the process of electron transfer on anode biofilms. To further evaluate this, Geobacter sulfurreducens was grown with acetate as fuel in a continuous flow 'ministack' system i...

Integrating an energy conversion or storage device with photodetectors into a self-powered system provides a promising route to future devices aimed at reduced size, low weight and high flexibility. We reported here the fabrication of a fully flexible self-powered photodetector nanosystem by integrating a flexible SnO2-cloth-based ultraviolet photodetector with a flexible SnO2-cloth-based lithi...

A fuller account of the scientific experiments involving particle radiation and linen cloth that explains the medieval dating of the Shroud along with all the known chemical and molecular effects of the Shroud’s body image can be found on the proposal on my website www.resurrectionoftheshroud.com/Information/proposal11.html These scientific experiments along with numerous other scientific, medi...

a r t i c l e i n f o High-performance microbial fuel cell (MFC) air cathodes were constructed using a combination of inexpensive materials for the oxygen reduction cathode catalyst and the electrode separator. A poly(vinyl alcohol) (PVA)-based electrode separator enabled high coulombic efficiencies (CEs) in MFCs with activated carbon (AC) cathodes without significantly decreasing power output....

Hybrid supercapacitor (HSC), which typically consists of a Li-ion battery electrode and an electric double-layer supercapacitor electrode, has been extensively investigated for large-scale applications such as hybrid electric vehicles, etc. Its application potential for thin-film downsized energy storage systems that always prefer high volumetric energy/power densities, however, has not yet bee...

This paper investigates the application of an electrochemical technique for the removal of a common herbicide, bentazone, from water streams using a carbon-based electrode. Activated carbon cloth with high surface area and narrow micropores was used as electrode. For a better understanding of the process, adsorption was investigated under both open circuit and controlled polarization conditions...

Tubular cathodes provide a method to obtain high surface areas for scaling up microbial fuel cells (MFCs), but the importance of the cathode shape is not known. We therefore examined power production using cathodes in various configurations (tubes or flat). The MFC with a single internal carbon cloth tube cathode (71 W/m(3)) produced more power than previously obtained with an ultrafiltration m...

This paper reports chemical surface modification of a high area activated carbon cloth to engineer its affinity towards organic contaminants.
