Construction of Efficient Gram-Negative Biocatalysts for Lignocellulose Conversion

Oct 18, 2011

David Keating

Research within the Great Lakes Bioenergy Research Center aims to better understand the bottlenecks associated with bioconversion of lignocellulose to liquid transportation fuels, knowledge which will then be used to improve the efficiency of this process. Much of these studies are currently...

Hydrothermal Fabrication of Ordered SnO2 Nanorod Arrays by Liquid Phase Conversion Process for Dye-Sensitized Solar Cells

Oct 18, 2011

Umang V. Desai

One-dimensional semiconductor materials have attracted significant research interest because of their unique properties for various technological applications. SnO 2 , as a wide band-gap semiconductor material is a promising photoanode material for dye-sensitized solar cells because of its fast...

Effect of Column Temperature On HPLC Separation of Acetic Acid and Levulinic Acid

Oct 18, 2011

Rui Xie

High performance liquid chromatography (HPLC) is a routine method in the analysis of degradation products in the prehydrolysate or the hydrolysis liquor of lignocellulosic biomass. Cation exchange column chromatography with a metal counter ion has been used for the quantitative analysis of...

Novel Electrochemical Process for Capture of CO2 From Power Plant Flue Gas

Oct 18, 2011

Saurav Datta

Energy efficient capture of CO 2 released from coal based power plants is a major challenge to reduce greenhouse gas emissions. The existing commercial technologies require substantial energy inputs in the form of heat and vacuum which leads to around 30 % parasitic energy loss. To overcome this...

Improving Corn Stover Reactivity In Low Severity Pretreatment Through Deacetylation and Disc-Refining

Oct 18, 2011

Xiaowen Chen

The current “state-of-art” dilute acid pretreatment to produce bio-ethanol from corn stover requires severe conditions to overcome biomass recalcitrance, which, in turn, offers 70~80% xylose monomer yield and 5~7% furfural yield. However, high acid loadings and high reaction temperatures harm the...

PAT Application and Validation of Online Particle Sizing Measurement for Controlling a Critical Quality Attribute

Oct 18, 2011

Kevin J. Bittorf

In accordance with ICH Q8/9/10 and the FDA QbD initiative, companies are adding more and more PAT equipment, installing more sophisticated control systems, and moving to real-time release. Throughout this process, many questions have come to light. How is PAT justified for controlling quality...

Ab-Initio Study of Glycerol Dehydration Mechanisms with Explicit Solvent Treatment

Oct 18, 2011

Tim Courtney

Glycerol produced as a waste product in biodiesel production has interesting potential as a low-cost biomass-derived feedstock for chemical processing. A process of current academic and commercial interest is the acid-catalyzed dehydration of glycerol to acrolein, a valuable platform chemical. Such...

Hydrogen Production From Deliquescence of Ammonia Borane

Oct 18, 2011

Bing-Hung Chen

Chemical hydride is one of the most potential hydrogen storage materials which can effectively increase hydrogen storage capacity. To meet the new goal of U.S. department of energy (DoE), 4.5wt% and 5.5 wt% of gravimetric hydrogen density capacity by 2010 and 2015, respectively, ammonia borane (AB...

Structural Characterization of AHP-Pretreated Biomass

Oct 18, 2011

Muyang Li

Alkaline hydrogen peroxide (AHP) pretreatment is exceptionally well-suited to grasses, yielding high digestibilities at low enzyme loadings, while generating relatively few fermentation innhibitors. For AHP pretreatment, the question of how structural and chemical compositional changes within the...
