BACKGROUND The European Union has made it a strategic objective to develop its biofuels market in order to minimize greenhouse gas (GHG) emissions, to help mitigate climate change and to address energy insecurity within the transport sector. Despite targets set at national and supranational levels, lignocellulosic bioethanol production has yet to be widely commercialized in the European Union. ...

Presence of water during biodiesel production and purification processes, storage and use in compression ignition (diesel) engines causes problems that cannot be ignored. These problems include: difficulties in biodiesel processing especially during alkali-catalyzed transesterification process, deterioration of biodiesel quality, decrease in heat of combustion, corrosion of fuel system componen...

This review presents microbial fuel cells (MFCs) that convert biochemical metabolic energy into electrical energy. Microbes can be fed with waste products rich in organic matter (domestic wastewater, lignocellulosic biomass, brewery wastewater, starch processing wastewater, landfill leachates etc.) to generate electricity. MFCs can also be used for wastewater treatment, as biosensors and produc...

Increasingly pervasive networks fuel the research and development of new data management technologies to deal with the streaming data and continuous queries that are typical of data stream applications. TelegraphCQ is the next generation of Telegraph System, which is a highly adaptive streaming dataflow system with shared processing that uses building blocks from conventional relational databas...

acute toxicity test on common carp weighing 18 grams and length 12 cm was performed. with concentrations of 0, 2, 5, 10, 20, 40, 60, 80, 100, 200, 400, 600, 800 and 1000 ppm measured at 0, 24, 48 and 96 hours were considered for commercial diesel . processing data using spss software and statistical analysis probit analysis was performed with a confidence level of 95%. the common carp no deaths...

Green fuel-driven thumb sized motors (TSM) were designed and optimized by 3D printing to explore their in-situ remediation applications in rare studied underwater area. Combined with areogel processing and specialized bacteria domestication, each tiny TSM could realize large area pollutant treatment precisely in an impressive half-automatically manner.
