The new two-dimension position sensitive TRD prototype architecture for CBM experiment developed by us is based on diagonally split rectangular pads of the read-out electrode [1]. The choice of triangular-pad geometry allows for position determination in both coordinates: across and along the pads, respectively. The TRD prototype used in the present tests has a readout electrode of 25 μm thickn...

In this study, we evaluated the removal of nitrate from synthetic groundwater by a cathode followed by an anode electrode sequence in the electrochemical flow-through reactor. We also tested the feasibility of the applied electrode sequence to minimize the production of ammonia during the nitrate reduction. The performance of monometallic Fe, Cu, Ni, and carbon foam cathodes was tested under di...

Microbial cell populations in polluted water were determined by using a fuel cell-type electrode. The electrode was composed of a Pt anode, a Pt-K3Fe(CN)6-K4Fe(CN)6 cathode, and a cation-exchange membrane for separating two electrode compartments. The principle of microbial cell number determination is based on sensing a redox dye reduced by microorganisms with the electrode. Sample solutions c...

BACKGROUND Purified terephthalic acid (PTA) wastewater from a petrochemical complex was utilized as a fuel in the anode of a microbial fuel cell (MFC). Effects of two important parameters including different dilutions of the PTA wastewater and pH on the performance of the MFC were investigated. METHODS The MFC used was a membrane-less single chamber consisted of a stainless steel mesh as anod...

Multiple Hemoglobin Components in Cutthroat and Rainbow Trout Multiple hemoglobin components in fish is a well-documented phenomenon, with cutthroat trout having twelve (Figure 1a) and rainbow trout having nine (Figure 1b) hemoglobin components (Braman et al.1977). A high-resolution starch gel electrophoresis method was developed to resolve eight negatively charged hemoglobin components from bo...

2-Amino-5,10-dioxo-4-aryl-5,10-dihydro-4H-benzo[g]chromene-3-carbonitrile derivatives are obtained in excellent yields with a simple and efficient procedure.This reaction can occur using electrocatalytic multicomponent chain transformation of aryl aldehydes, 2-hydroxynaphthalene-1,4-dione and malononitrile under neutral and mild conditions. Moreover, electrolysis is done in CH3CN as solvent, Te...

A better understanding of how anode and separator physical properties affect power production is needed to improve energy and power production by microbial fuel cells (MFCs). Oxygen crossover from the cathode can limit power production by bacteria on the anode when using closely spaced electrodes [separator electrode assembly (SEA)]. Thick graphite fiber brush anodes, as opposed to thin carbon ...

A three electrode cell for use with solid electrolytes is presented. The provides a stable reference voltage and leads artefact-free impedance spectra while being easily assembled airtight. To prove its versatility several combinations of electrodes were employed, enabling to rapidly assess the main differences between argyrodite vs. lithium phosphorous sulphide electrolytes, oxide active mater...

A small, off-axis mesh-anode electrode at one plasma-column end is used to create a paraxial channel of electron current and depleted density in the large plasma device upgrade at UCLA. We show that the on-axis, larger, surroundingplasma column rotates about its cylindrical axis because a radial electric field is imposed by a multiple-segmented-disc termination electrode on the same end as the ...

The development of alternative anode materials out of flexible composite nanofibers has seen a growing interest. In this paper, binary carbon nanofiber electrodes of SnO2/NiO and Sn nanoparticles are produced using a scalable technique, Forcespinning (FS), and subsequent thermal treatment (carbonization). The Sn/C composite nanofibers were porous and flexible, while the SnO2/NiO composite nanof...
