Impact of Government Biotechnology Regulations on Biofuel Development

Glass D.J., D. Glass Associates, Inc., US

Biofuels projects involving the use of advanced biotechnology strategies may be affected by government biotechnology regulation. Transgenic plants engineered to improve biofuels feedstocks may be regulated under the U.S. Department of Agriculture’s biotechnology regulations. Genetically [...]

High Quality Biodiesel from Spent Coffee Grounds

Misra M., Kondamudi N., Mohapatra S.K., John S.E., University of Nevada Reno, US

Spent coffee grounds are proved to be a potential source for high quality biodiesel production.

Methanol Production for Renewable Energy Storage and Distribution

Bishop W., Consultant, US

Methanol production technology and systems are being developed to provide an economically viable fuel from a renewable energy source. Neither fossil fuel nor biological feedstock is required. The energy is principally used to extract hydrogen [...]

Novel Membrane Technology for Green Ethylene Production

Balachandran U., Lee T.H., Dorris S.E., Scouten C.G., Marshall C.L., Argonne National Laboratory, US

Today ethylene is produced (approximately 60 billion pounds in 2005 in U.S.A. alone) by thermal cracking of ethane in presence of steam requiring substantial energy input. The equilibrium conversion is thermodynamically limited. Because of direct [...]

Nano-docking stations for synfuels catalysts on carbon nanotubes

Graham U.M., Khatri R.A., Coville N.J., Dozier A., Davis B.H., University of Kentucky, US

Carbon nanotubes (CNTs) represent a distinctive class of catalyst supports and provide promising scenarios for catalytic reactions including fuel synthesis. The mobility of supported catalytic nanoparticles (NPs) on CNTs typically results in agglomeration leading to [...]

Analysis of the US Fuel Ethanol Industry and Market Expectations

Wiselogel A., Kistner J., Althoff K., BBI International, US

From humble beginnings as part of Henry Ford’s vision of an agricultural based transportation industry and a rebirth as a fuel additive, ethanol is quickly approaching a 10% share of the US gasoline market. Fuel [...]

Catalytic Conversion of Biomass to Hydrocarbons

Cortright R.D., Virent Energy Systems, US

Virent Energy Systems, Inc.’s patented Aqueous-Phase Reforming (BioFormingTM ) process enables the economical and energy efficient use of plant based sugars to generate the many hydrocarbon products that drive the world economy. Virent’s patented catalytic [...]

Clean Waste Tech: Anaerobic Composting in Bioreactor Landfills

Augenstein D., Benemann J., Yazdani R., IEM, Inc., US

The controlled bioreactor landfill has been demonstrated at progressively larger scales, now up to 300,000 tons waste in multiple cells, since 1994. The approach enables recovery of renewable methane energy from landfills to maximum potential. [...]

Si-Based Process Aware SPICE Models for Statistical Circuit Analysis

Krishnamurthy S., Dasarapu V.K., Mahotin Y., Ryles R., Roger F., Uppal S., Mukherjee P., Cuthbertson A., Lin X-W, Synopsys, Inc., US

This paper describes methodology for constructing compact SPICE models as a function of process parameter variations. The methodology involves global extraction of process-dependant SPICE model parametersfrom silicon data. The robustness of this methodology was tested [...]

Compact Models for Double Gate MOSFET with Quantum Mechanical Effects using Lambert Function

Abebe H., Morris H., Cumberbatch E., Tyree V., University of Southern California, ISI, US

This paper is a continuation of the work we presented in the 2006 IEEE UGIM Proceedings. Iterative compact device models with quantum mechanical effects for a Double Gate (DG) MOSFET are presented using the Lambert [...]
