Methane-producing bioelectrochemical systems (BESs) are a promising technology to convert renewable surplus electricity into the form of storable methane. One of the key challenges for this technology is the search for suitable cathode materials with improved biocompatibility and low cost. Here, we study heat-treated stainless steel felt (HSSF) for its performance as biocathode. The HSSF had su...

Bioelectrochemical systems (BES) and forward osmosis (FO) are two emerging technologies with great potential for energy-efficient water/wastewater treatment. BES takes advantage of microbial interaction with a solid electron acceptor/donor to accomplish bioenergy recovery from organic compounds, and FO can extract high-quality water driven by an osmotic pressure. The strong synergy between thos...

Biochemical oxygen demand (BOD) is a widely used index of water quality in wastewater treatment; however, conventional measurement methods are time-consuming. In this study, we analyzed a novel flame-oxidized stainless steel anode (FO-SSA) for use as the probe of bioelectrochemical system (BES)-based biosensors to monitor the BOD of treated swine wastewater. A thinner biofilm formed on the FO-S...

INTRODUCTION Various optical measurement techniques have been developed for the characterization of surface states during electrochemical processes. Surface plasmon resonance (SPR) spectroscopy has been used in combination with electrochemistry to investigate the electronic structure of metal-electrolyte interfaces [1]. We reported the current efficiency of refractive index changes that occurre...

This work achieved nitrogen recovery from the wastewater treatment by bioelectrochemical system with concept of biohythane generation. In this study, 3D network electrode could improve generation to reduce energy consumption recovery, achieving highest production rate at 0.123 m3 m−3 treated obtain 0.77 kWh kg−1 N under 0.8 V, significantly lower than other traditional technologies (at about 1....

CD105 is a well-known tumor metastasis marker and useful for early monitoring of metastasis and cancer relapse. It is important to generate rapid, reliable and precise analytical information regarding CD105 levels. To establish a simple, selective and sensitive detection method, we prepared an immunosensor with novel bioconjugates based on Pt nanoparticles, thionin acetate and antibodies. The p...
