We investigated the mechanism of Congo red degradation and bacterial diversity in a single-chambered microbial fuel cell (MFC) incorporating a microfiltration membrane and air–cathode. The MFC was operated continuously for more than 4 months using a mixture of Congo red and glucose as fuel. We demonstrated that the Congo red azo bonds were reduced at the(More)
In this paper, a new monolithically integrated, digitally-controlled variable gain amplifier (DVGA) is presented. The DVGA includes a gain block, a digital step attenuator (DSA), and a ¼ W driver amplifier, fabricated by using commercial GaAs BiFET process. This high performance, low cost DVGA operates from 100MHz to 4000MHz, with 0.5dB step and(More)
Two single nucleotide polymorphisms (SNPs), rs2280788 (−28C>G) and rs2107538 (−403G>A), in the promoter region of chemokine (C–C motif) ligand 5 (CCL5) was reported to be involved in the immunoglobulin E (IgE) expression and IgE-mediated allergic reactions. This study was to investigate the characteristics of total serum IgE level, specific allergen(More)
A monolithic integrated single chip RF variable gain low noise amplifier (VGLNA) based on GaAs BiFET technology is demonstrated in this work. The LNA could be operated from 700MHz to 3GHz. The measured NF is 1dB at both 975MHz and 1.75GHz. The gain of the VGLNA can be varied from a maximum of 36dB down to -13dB at 1.75GHz. Measured Output IP3 is 38.4dBm and(More)
Electrostatic discharge (ESD) protection structures in the D-Mode GaAs HEMT technology are commonly constructed using either stacked Schottky diode or Single-Gate clamp. This paper develops an improved ESD protection clamp based on a novel multi-gate pHEMT in D-Mode technology. With similar layout area, the proposed ESD protection clamp can carry much(More)
Air-cathode, microbial fuel cells (MFC) with different anode surface areas were evaluated for simultaneous decolorization of Congo Red and bioelectricity production. Doubling the anode area from 18 to 36 cm2 increased net power by 150 % (0.16–0.4 mW), normalized power (per anode surface area) by 22 % (88–107 mW m−2) and Congo Red decolorization by 163 %(More)
In order to increase the power output and reduce the cost of MFCs, micro filtration membrane (MFM) air-cathode MFC (MFM-MFC) and proton exchange membrane (PEM) air-cathode MFC (PEM-MFC) were compared in the performance of the simultaneous decolorization of azo dye and power generation. Batch test results showed that the PEM-MFC produced a maximum power(More)
To exploit the outstanding ability of microbial fuel cell (MFC) for simultaneous treatment of azo dye - polluted wastewater and bioelectricity generation, the effect of a representative azo dye - Congo red on the electrochemical characteristics of the bioanode of an air-cathode single chambered MFC was investigated in detail. The electrochemical impedance(More)
