Researchers from University of New Mexico Report Findings in Carbon Research

February 7, 2014



By a News Reporter-Staff News Editor at Science Letter -- Research findings on Carbon Research are discussed in a new report. According to news reporting from Albuquerque, New Mexico, by NewsRx journalists, research stated, "Surface roughness, porosity and contactangles of different carbon paper materials (TORAY paper with PTFE from 0% to 60% of and SGL paper with 0% and 20% of PTFE) suitable as electrodes in microbial fuel cells were investigated. The changes of contact angle between dry and clean anode surfaces and the ones after exposure to wastewater were measured using different liquids (pure water and sodium acetate solutions)."

The news correspondents obtained a quote from the research from the University of New Mexico, "The results showed that bacterial attachment to the carbon papers caused a significant decrease in the contact angle, shifting the surface property from highly hydrophobic to slightly hydrophobic or even hydrophilic. The quantity of biofilm attached on the anode surface decreased with the increase in PTFE content. Positive correlation between dry biomass content and the amount of pores at the small scale (5-10 mu m) was observed. The start up time of MFCs was shortened by using the carbon anodes without PTFE or with low PTFE content (

According to the news reporters, the research concluded: "After several cycles of MFC operation, the performances became similar (20-30 mV of differences) regardless of the carbon anode used."
