The past decade has seen rapid growth in the global biofuels sector – particularly in the US and the EU. This has had important implications for the global livestock industry – both by raising the cost of feed grains and oilseeds and by forcing onto the market a large supply of biofuel by-products, many of which end up in livestock feed rations. This paper systematically investigates the impact...

This research paper examines the feasibility for second-generation biofuels as an alternative fuel supply for both pistonand turbine-powered general aviation aircraft. With relevant research given to the history of biofuels and their technologic development, this paper aims to provide an analysis of biofuel development, biofuel technology and its potential impacts, specifically for the aviation...

This paper presents an assessment of the potential impact of the EUs biofuel directive on European land use and biodiversity. In a spatially explicit analysis, it is determined which ecologically valuable land use types are likely to be directly replaced by biofuel crops. In addition, it is determined which land use types may be indirectly replaced by biofuel crops through competition over land...

Since late 2006, biofuel policies have caused high grain/oilseed prices by creating a link between crop and biofuel policies. The value of agricultural trade has increased sharply, mostly because of high prices, not increased trade volume. Biofuel policies have little to do with the agenda of the Doha trade negotiations but have had indirect effects in that production subsidies and import barri...

Printable wearable lactate biosensors have attracted significant attention, and printable biofuel cells gained popularity as suitable power supplies for these sensors. However, realizing an appropriate supply the practical application of sensors devices, it is necessary to improve output cells. In this study, we fabricated a cell that employed paper substrate using screen printing. The proposed...

Here, a low-cost glucose/O 2 Y-shaped microfluidic biofuel cell was developed using printed circuit board for microelectrode construction. A double-side tape based on the pressure-sensitive adhesive used microchannel fabrication. nanocomposite that consisted of reduced graphene oxide gold nanoparticles (AuNPs), and poly neutral red connected to enzymes applied copper electrode surface. The Aspe...

The electrical contacting of redox enzymes with electrodes is the most fundamental requirement for the development of amperometric biosensors and biofuel cell elements. For the effective electrical communication of redox enzymes with electrodes the use of electron relay units that transport the electrons between the enzyme redox center and the conducting surface is essential. Also, the structur...
