A New Generation of Zirconia Supported Metal Oxide Catalysts for Converting Low Grade Renewable Feedstocks to Biodiesel

Oct 17, 2011

Manhoe Kim

A new class of zirconia supported metal oxide catalysts has demonstrated the ability to convert low quality bio-oils, high in FFA, to biodiesel. Operating at mild to moderate reaction conditions, 195°C and 300psi, these catalysts can perform simultaneous esterification and transesterification...

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...

Graphitic Material with Engineered Graphene Units for High-Power Li Ion Battery Electrodes

Oct 16, 2011

Cary M. Hayner

Li ion batteries capable of delivering a high current without sacrificing voltage or energy density are highly desirable, since they can be recharged faster and provide longer operation time when used in devices that demand high power. In the current generation of batteries using graphite as the...

Novel Quaternary Ammonium Ionic Liquid Electrolyte for Stable, High Capacity Si Nanowire Based Li-Ion Battery

Oct 16, 2011

Vidhya Chakrapani

In recent years, there has been interest in silicon nanowires as an anode for Li-ion battery because of its large gravimetric capacity of 4200 mAh/g. 1D nanostructure are essential because they permit radial strain relaxation of mechanical stress which occurs due to the volumetric expansion (>...

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...

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...
