Bio-fuel cells are alternative energy devises based on bio-electrocatalysis of natural substrates by enzymes or microorganisms. Here we review bio-fuel cells and bio-batteries based on the recent literature. In general, the bio-fuel cells are classified based on the type of electron transfer; mediated electron transfer and direct electron transfer or electronic charge transfer (ECT). The ECT of...

This paper applies the direct digital frequency synthesis technology (DDS) to build a controllable variable frequency and waveforms of the bio-diesel fuel phacoemulsification system. The optimal operating parameters of phacoemulsification system are studied by orthogonal experiment. In the experiment, the ultrasonic frequency, waveform, power and process time are changed to study the stability ...

concurrent renewable energy production and wastewater treatment are two main reasons for using microbial fuel cells (mfcs). in this study, real wastewater was used for treating and power generation by air cathode microbial desalination cells (acmfc). the total duration of voltage generation by acmfc was about 151.9 ±23.2 h. the maximum voltage produced from municipal wastewater treatment was 27...

Bio-jet fuel has attracted a lot of interest in recent years and has become a focus for aircraft and engine manufacturers, oil companies, governments and researchers. Given the global concern about environmental issues and the instability of oil market, bio-jet fuel has been identified as a promising way to reduce the greenhouse gas emissions from the aviation industry, while also promoting ene...

This article employs the notion of translation introduced in ANT literature to study the current bio-fuel development in Indonesia. Despite the presence of some activities by scientists, businessmen, policy makers, and farmers, diffusion of bio-fuel innovation seems to remain very limited. The article aims at understanding the bio-fuel development trajectory by seeking to disclose a variety of ...

BACKGROUND Bio-jet fuels compatible with current aviation infrastructure are needed as an alternative to petroleum-based jet fuel to lower greenhouse gas emissions and reduce dependence on fossil fuels. Cradle to grave life cycle analysis is used to investigate the global warming potential and fossil fuel use of converting poplar biomass to drop-in bio-jet fuel via a novel bioconversion platfor...

Compression ignition engine is a popular prime mover in rural areas, particularly in the places where electrical power is not available. The rapid depletion of fossil fuel has stimulated worldwide efforts to produce alternative fuel to diesel fuel. Use of bio fuel as an alternative fuel can contribute significantly towards the twin problem of fuel crises. The fuel of bio origin may be the bio d...

This research work depends on enhancing the execution of the diesel engine when they utilized bio diesel oil as an optional fuel without real alteration of engine design. It is also required to grow non edible feed stocks in the waste or marginal land of Gujarat. Work goal is to recognize best suitable Bio-Diesel mix by keeping numerous parameters on it. Bio-Diesel mixes will be given credit sc...

Bio fuel plays an important role in the energy production of the forest industry. The initial moisture of the fuel typically varies between 50 63 w-%. A multi stage drying concept has been developed for the drying of wet bio fuel. To adjust the temperature levels in the multi stage drying system there must be a simple and fast method to define the fuel initial moisture. A method to define the i...
