Investigating Fundamental Electrochemical Processes In a Li-O2 Battery

Oct 16, 2011
Bryan McCloskey
Li-air batteries have received significant attention as a potential high specific energy alternative to current state-of-the-art rechargeable Li-ion batteries. Nevertheless, published Li-air embodiments have only achieved a small fraction of their enormous theoretical specific energy (11,700 Wh/kg...

Fermentation of Carbon Dioxide to Ethanol

Oct 16, 2011
Chang Chen
Many fermentation processes have been used to convert biomass to various fuels. Syngas, which is a mixture of CO, CO 2 , and H 2 , is one process being studied for the production of ethanol. Per mole of ethanol produced, 12 electrons are consumed. H 2 and CO are the electron sources in syngas...

Rule of Thumb for Reactor Design and Process Condition for Biodiesel Production

Oct 16, 2011
Masato Kouzu
The rule of thumb for reactor design and process condition for biodiesel production is introduced. The important aspect includes type of feedstock oil, catalyst selection, methanol/oil ratio, quality of the produced biodiesel. When low quality plant oil is used as the feedstock, its pre-treatment...

Thermochemical Hydrogen Production by Alkali Metal Oxides

Oct 16, 2011
Hiroki Miyaoka
In this work, we have focused a thermo chemical hydrogen production from water by using alkali metal oxides. This system consists of three step reactions. First one is H 2 generation by the reaction of hydroxide and metal 2MOH+2M→2M 2 O+H 2 (endothermic). From the oxide as the product of first...

Atomic Layer Deposition of Nanoscale Materials for Energy Conversion

Oct 16, 2011
Marja N. Mullings
For a number of technologies, including microelectronics and energy conversion devices, feature sizes are becoming increasingly small, and the need for precise control over costly materials continues to grow. In addition to decreasing length scales, it is important that limited natural resources...

Natural Gas Future

South Texas Section Webinar
Apr 7, 2011
Michael J. Economides

Natural gas, at prices significantly below BTU parity with oil for a long time to come, will certainly play a pivotal role in world energy supply and will move towards becoming the premier fuel of the world economy. A significant feature of future gas prices is that they are likely to be technology driven, similar to oil prices, rather than resources driven.
