Ethanol or ethyl alcohol (C2H5OH) is a clear, volatile, colourless, and polar organic solvent. It is a source of energy being utilized with petrol/gasoline for vehicle fuel. Recently, the conventional fuel prices are increasing continuously, and further due to their limited natural resource; there is a huge demand to utilize the renewable biofuels produced from agriculture products. It is expec...

Model predictive control represents one of the most promising methods, also in fast industrial applications like a Diesel engine. But especially Diesel engine control meets problems of uncertainties and disturbances, thus model-plant mismatch is omnipresent, which obviously decreases the performance of model based control. This paper compares different robust predictive control strategies appli...

Effects of cathode types on the long-term stability of microbial fuel cell (MFC) and the anodic microbial communities were studied using K(3)Fe(CN)(6) catholyte (R1), air cathode (R2) and biocathode (R3) over a testing time of 400 d. Upon 400 d of testing, the maximum power densities (P(max)) of R1 and R2 decreased by 44% and 37%, and the Coulombic efficiencies (CEs) decreased 8.4% (R1) and 2.0...

For the development of long lasting portable microbial fuel cells (MFCs) new strategies are necessary to overcome critical issues such as hydraulic pump system and the biochemical substrate retrieval overtime to sustain bacteria metabolism. The present work proposes the use of a synthetic solid anolyte (SSA), constituted by agar, carbonaceous and nitrogen sources dissolved into diluted seawater...

Solid oxide fuel cells (SOFC) are receiving an increasing level of attention for both smalland large-scale applications due their high fuel flexibility compared to other types of fuel cells. This article reviews recent work in SOFC materials research, with an emphasis on anodes that can directly utilize hydrocarbon fuels.

introduction population growth, increasing consumption of natural energy sources, the increasing use of fossil fuels, especially the oil and gas industry in recent years with the energy imbalance management has led to emergence of global energy crisis. moreover, rapid urbanization and industrialization have substantially increased the amount of high-strength wastewater being produced, which in ...

various combustion characteristics and properties are studied while selecting a fuel for any engine. the choice of the engine and fuel are highly interrelated. vegetable oil is one obvious fuel particularly because their fuel properties are closer to diesel fuel. two important properties, the cetane number and the calorific value are similar to diesel. hence diesel engines can be operated on ve...

Microbial fuel cells (MFCs) represent a clean and renewable energy resource. To date, power generation in MFCs is severely limited. In order to improve performance, a wide range of techniques have been utilised for a fundamental scientific understanding of the components and processes and also to investigate MFC performance bottlenecks. In this tutorial review, we discuss the electrochemical/el...
