“…After CS/a-Fe 2 O 3 modification, the performance of MFCs was dramatically increased. The current of this substrate system is far higher than the current (2 · 10 -6 A), which was obtained for the reported system ( Ji et al, 2011).…”

“…For example, the layer-by-layer assembly of chitosan (CS) and aFe 2 O 3 nanorod could improve the transferring abilities of electrons. However, the resultant current density of the MFCs was found to be very low ( Ji et al, 2011;Martin et al, 2011). The maximum current observed by using CS/a-Fe 2 O 3 -modified Indium Tin oxide (ITO) conductive glass and the Shewanella loihica PV-4 bacteria in MFCs is just around 2 · 10 -6 A, and still is very low ( Ji et al, 2011).…”

To the best of our knowledge, there still is no study focusing on using CS/a-Fe 2 O 3 -modified ITO to improve the performance of MFCs by using high electron producing lactic acid bacteria.…”

Indium Tin Oxide (ITO) conductive glass was modified by layer-by-layer modification of chitosan (CS) and aFe 2 O 3 nanoparticles. Lactic acid bacteria were the source of electrons in the studied microbial fuel cells (MFCs) system. When ITO/(CS/a-Fe 2 O 3 ) 4 /CS was the anode, external resistance was 626.6 O, while maximum current and maximum power density were 1.16 mA and 0.122 W/m 2 , respectively. These values were far higher than already reported results. Atomic force microscope image proved that ITO/(CS/a-Fe 2 O 3 ) 4 /CS surface was rougher than blank ITO and ITO/(CS/a-Fe 2 O 3 ) 8 /CS surfaces, which enable it to have a higher specific surface area for the microbes to grow. For ITO/(CS/a-Fe 2 O 3 ) 4 /CS, physical properties played a leading role, while the chemical properties mainly determined the surface morphology of ITO/(CS/a-Fe 2 O 3 ) 8 /CS. Lactic acid bacteria in fermentation waste could improve the current of MFCs. Layer-by-layer assembly of CS/a-Fe 2 O 3 could significantly improve the performance of MFCs.

Abstract:Nanorods in nanotechnology called a specific type of morphology of nanoscale materials that their dimensions range is from 1 to 100 nm. Nanorods can be synthesized from metal or semi-conductive material with a surface to volume ratio of 3-5. One method of making nanorods is direct chemical method. Ligands compounds as a shape control agents cause growth the nanorods and create stretched and extended modes of them. In recent years, magnetic nanorods are one of the nanorods that have been raised in the field of nano medicine [Nath S, Kaittanis C, Ramachandran V, Dalal NS, Perez JM. Synthesis, magnetic characterization, and sensing applications of novel dextran-coated iron oxide nanorods. Chem Mater. 2009;21:1761-7.]. Superparamagnetic properties of magnetic nanorods causes to sensing be done with high accuracy. In addition, other applications of magnetic nanorods are in the field of separation and treatment [Hu B, Wang N, Han L, Chen ML, Wang JH. Magnetic nanohybrids loaded with bimetal core-shell-shell nanorods for bacteria capture, separation, and near-infrared photothermal treatment. Chemistry. 2015;21:6582-9.]. Therefore, in biomedical applications, the nanorods are used usually with biological molecules such as antibodies [Schrittwieser S, Pelaz B, Parak WJ, Lentijo-Mozo S, Soulantica K, Dieckhoff J, et al. Homogeneous protein analysis by magnetic core-shell nanorod probes. ACS Appl Mater Interfaces. 2016;8:8893-9.]. For this purpose, in the present work we will try to introduce magnetic nanorods and mention their different methods of synthesis and applications.

Microbial fuel cells (MFCs) have attracted considerable interest due to their potential in renewable electrical power generation using the broad diversity of biomass and organic substrates. However, the difficulties in achieving high power densities and commercially affordable electrode materials have limited their industrial applications to date. Carbon materials, which can exhibit a wide range of different morphologies and structures, usually possess physiological activity to interact with microorganisms and are therefore fast-emerging electrode materials. As the anode, carbon materials can significantly promote interfacial microbial colonization and accelerate the formation of extracellular biofilms, which eventually promotes the electrical power density by providing a conductive microenvironment for extracellular electron transfer. As the cathode, carbon-based materials can function as catalysts for the oxygen-reduction reaction, showing satisfying activities and efficiencies nowadays even reaching the performance of Pt catalysts. Here, first, recent advancements on the design of carbon materials for anodes in MFCs are summarized, and the influence of structure and surface functionalization of different types of carbon materials on microorganism immobilization and electrochemical performance is elucidated. Then, synthetic strategies and structures of typical carbon-based cathodes in MFCs are briefly presented. Furthermore, future applications of carbon-electrode-based MFC devices in the energy, environmental, and biological fields are discussed, and the emerging challenges in transferring them from laboratory to industrial scale are described.
