“…The preparation of the wirelessly powered scaffolds, in particular, is relatively complex. On the other hand, the exploitation of the glucose and oxygen present in human body to produce electricity has long been studied . However, no work has been reported involving the design of a nerve scaffold with self‐powered ES based on the consumption of glucose and oxygen.…”

Electrical stimulation (ES) is widely applied to promote nerve regeneration. Currently, metal needles are used to exert external ES, which may cause pain and risk of infection. In this work, a multiblock conductive nerve scaffold with self‐powered ES by the consumption of glucose and oxygen is prepared. The conductive substrate is prepared by in situ polymerization of polypyrrole (PPy) on the nanofibers of bacterial cellulose (BC). Platinum nanoparticles are electrodeposited on the anode side for glucose oxidation, while nitrogen‐doped carbon nanotubes (N‐CNTs) are loaded on the cathode side for oxygen reduction. The scaffold shows good mechanical property, flexibility and conductivity. The scaffold can form a potential difference of above 300 mV between the anode and the cathode in PBS with 5 × 10−3 m glucose. Dorsal root ganglions cultured on the Pt‐BC/PPy‐N‐CNTs scaffold are 55% longer in mean neurite length than those cultured on BC/PPy. In addition, in vivo study indicates that the Pt‐BC/PPy‐N‐CNTs scaffold promotes nerve regeneration compared with the BC/PPy group. This paper presents a novel design of a nerve scaffold with self‐powered ES. In the future, it can be combined with other features to promote nerve regeneration.

“…Carbon derivatives when used with metal nanoparticles are being reported to modify the catalytic activity of metal electrocatalysts [30][31][32]. Carbon nanotubes containing iron nanocatalyst shows a high stability and remarkable reactivity when used in polymer membrane fuel cells [33]. Graphene when used with a coating of cobalt nanoparticles is found to be more durable and shows positive catalysis for the reduction of oxygen in fuel cells in the league of noble metals like platinum [34][35][36].…”

The increasing concerns for sustainable economy and alarming environmental health are making researchers to pay serious attention to bio-fuels that too primarily synthesized from the biomass. An energy transforming machine extracting energy directly from biomass would be an idyllic condition. Regrettably, devices using sustainable energy resource have shown to have low output, not meeting the demands of practical appliances. Serious efforts are being dedicated to research on the prospects of bio-fuel powered fuel cells as green energy exchange tool. To comprehend this, scientists are working on the production and expansion biological fuel cell (BFC) which are electro-chemical devices utilizing electro-active bacteria for producing electricity through oxidation. The materials used for electrodes in BFCs, should have conductivity, porosity, biocompatibility, low in cost and recyclability. The materials tested for BFCs are principally metalbased, carbon-based or purposely built advanced materials. The research efforts over the last decade have positioned macro-porous and composite of carbon-based nanostructures with controllable surface and electronic characteristics to be used as a support-matrix for metallic electro catalysts or as proficient non-metallic electro catalysts in BFCs. This review article discusses about the present challenges and future prospects in the field of current progresses in the field of carbon based catalysis system for biomass based microbial fuel cells which extract energy from biomass resources either directly or indirectly.

This paper addresses energy generated in a passive anion‐exchange membrane micro fuel cell (PAEMμFC) using glycerol from several kinds of sources: high‐purity glycerol (HPG), saponification process‐derived glycerol (SPDG), crude glycerol from sunflower oil biodiesel (CGSOB) and crude glycerol from cooking oil biodiesel (CGCOB). Spectrophotometry, volumetric Karl Fischer, gas chromatography, calorimetry, Fourier transform infrared, and cyclic voltammetry were employed for the glycerol samples characterization. The PAEMμFC was tested using 0.1M glycerol of each type, achieving power densities of 1.008, 0.932, 0.871, and 0.865 mW cm−2 for HPG, SPDG, CGSOB and CGCOB, respectively. On the other hand, commercially available software from ANSYS, Inc. was used to determine the fuel velocity and pressure in the fuel reservoir and current collector as a complementary evaluation of the PAEMμFC. The results obtained for the prices of the energy of each glycerol sample were presented in order to demonstrate that the cost of energy generated through HPG is approximately 16.5 times the SPDG energy cost and 130 times the CGCOB energy cost.
