The X-ray emission characteristics of a vacuum spark device operated with anode materials of various atomic numbers were studied. The temporal evolution of the X-ray emission was recorded by using five channels of high-speed PIN X-ray diodes. A time-integrated X-ray spectrometer was used to record the spectral distribution of the X-ray emission. The electron temperatures of the aluminium, coppe...

Mo, Cu-doped CeO2 (CMCuO) nanopowders were synthesized by the nitrate-fuel combustion method aiming to improve electrical and electrochemical properties of its Mo-doped (CMO) parent addition copper. An conductivity ca. 1.22·10−2 S cm−1 was measured in air at 800°C for CMCuO, which is nearly 10 times higher than that reported CMO. This increase associated with inclusion copper into crystal...

Non-corrosive, carbon-based materials are usually used as anodes in microbial fuel cells (MFCs). In some cases, however, metals have been used that can corrode (e.g. copper) or that are corrosion resistant (e.g. stainless steel, SS). Corrosion could increase current through galvanic (abiotic) current production or by increasing exposed surface area, or decrease current due to generation of toxi...
