Microbial electrosynthesis (MES) is an emerging technology which exploits microbial cells to convert CO2 into fuels, and value-added chemicals using electrons supplied by a solid-state cathode. Methane and acetic acid are typically the main CO2-reduction products attained in microbial electrosynthesis studies, although the production of other more valuable products has also been reported.

Nanocomposite membranes based on polyethersulfone(PES) and nanomagnetite have been investigated with regards to the effect of pretreatments on the electrochemical performance of microbial fuel cells (MFCs). Nanocomposite membranes containing various amounts of Fe3O4(5, 10, and20 wt%) were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, differential scanning calorimetry, and tensile tests.

In this study, we report about the preparation of magnetic polymer nanocomposites on the basis of isotactic polypropylene and magnetite Fe3O4 nanoparticles. The structure and composition of polymer nanocomposite materials have been studied by scanning electron microscopy, atomic force microscopy, and X-ray dispersive analysis. The magnetic properties of polymer nanocomposites based on PP+Fe3O4have been investigated.

In the present study, the influence of the temperature–time mode of crystallization (TTC) on the morphology and thermal properties of PP/Fe3O4 nanocomposite materials was investigated. The morphology of the nanocomposites prepared in different TTC mode was studied by atomic force microscope. AFM study shows that the root mean square roughness of samples is 90–95, 50, 21 nm for PP/Fe3O4@20, PP/Fe3O4@200 and PP/Fe3O4@20000 respectively. Thermo gravimetric analysis was employed to investigate the thermal stability of PP/Fe3O4 nanocomposites obtained applying different TTC modes.
