Nanotechnology has opened up new opportunities for the design of nanoscale electronic devices suitable for developing high-performance biofuel cells. Glucose-based biofuel cells as green energy sources can be a powerful tool in the service of small-scale power source technology as it provides a latent potential to supply power for various implantable medical electronic devices. By using physiol...
امروزه با توسعه روز افزون تکنولوژی mems و کاربردهای گسترده آن در مهندسی پزشکی می توان قطعاتی را طراحی نمود که قابل کاشت (implantable ) در داخل بدن باشد. اندازه گیری مقدار قند خون یکی از زمینه هایی می باشد که با توسعه تکنولوژی memsمورد توجه بوده است. در بیماران دیابتی نوع دوم، میزان قند خون بالا می باشد و از آنجایی که با افزایش قند خون احتمال بیهوشی نیز بالا می رود، لذا اندازه گیری قند خون بصورت...
In the last few decades, finding alternatives to fossil fuels has become a hot issue across all international frontiers. The Intergovernmental Panel on Climate Change (IPCC) has shed light on the feasibility of using biofuels to meet the growing energy demand as well as to reduce CO2 emissions which are a major cause of global warming, especially in the transportation sector. The...
Lipases (EC 3.1.1.3) comprise a biotechnologically important group of enzymes because they are able to catalyze both hydrolysis and synthesis reactions, depending on the amount of water in the system. One of the most interesting applications of lipase is in the biofuel industry for biodiesel production by oil and ethanol (or methanol) transesterification. Entomopathogenic fungi, which are poten...
Biofuels are receiving increased scientific attention, and recently different biofuels have been proposed for spark ignition engines. This paper presents the state of art using in engines (SIE). Different biofuels, mainly ethanol, methanol, i-butanol-n-butanol, acetone, blended together single dual issues evaluated as renewables SIE. The were compared with each other well fossil fuel Future SIE...
One of the main challenges of bioenergy sector development is the cost of biomass supply chain resulted from inefficient bioenergy production from low energy content biomass feedstocks, high logistics costs of biomass production, handling and transportation. Another main aspect to be considered is that the configuration of a biofuel supply chain can be dynamic which evolve over time. Growing de...

Considerable interest has been focused on miniature biofuel cells (BFCs) because of their portability and possibility to be implantable. Origami devices with hollow channels will provide novel insight into the assembly methods of miniature BFCs. Herein a miniature origami BFC has been fabricated from a MnO2-graphite flake consumed solid-state cathode. For further practical applications, miniatu...
