Active Species Concentration Effects On Performance for a Non-Aqueous All-Vanadium Redox Flow Battery

Oct 19, 2011

Aaron A. Shinkle

Redox flow batteries (RFBs) are being developed for large-scale energy storage, uninterruptable grid-independent power supplies and load-leveling systems for solar or wind power. Aqueous chemistries are used for all current commercial RFBs, therefore, cell potentials are limited to the stability...

Towards Developing Anaerobic Digestion Based Biorefinery – Research On Food Wastes As Feedstock

Oct 19, 2011

Shulin Chen

Anaerobic digestion (AD) is a proven technology for waste treatment. However, as the organic material becomes more valuable and being treated as resources, traditional AD process is no longer adequate. The Bioprocessing and Bioproduct Engineering Laboratory at Washington State University has been...

Modeling a Reactive Crystallization with a Reduced Population Balance Equation for Dissolution and Growth to Control Critical Quality Attributes

Oct 19, 2011

Daniel Patience

Modeling has always been a powerful weapon in a chemical engineer’s arsenal. Use of modeling should be considered a key piece in the application of Quality by Design (QbD) in drug substance and drug product development. In this study, reaction, dissolution and growth kinetics are determined for a...

Prasad Peri

Inhalation Powders have become an important dosage form in developing products for delivery to the lungs. Since the approval of the first DPI in the US in the late 1990’s there has been a rapid surge in the number of drug development programs involving Dry Powder Inhalers. The draft MDI/DPI...

Aging of Biomass Fast Pyrolysis-Oil and Process Strategies to Produce Stable Pyrolysis Oils

Oct 19, 2011

Charles A. Mullen

Fast pyrolysis bio-oils are unstable due to a variety of factors, the most important being the high concentration of reactive oxygen-functionalized organic molecules, especially carbonyl containing compounds. Condensation and oligomerization reactions of these molecules lead to an increase in the...

Lifetime and Efficiency Studies of Zinc/Bromine Electrochemical Energy Storage In Large Scale Renewable Energy Applications

Oct 19, 2011

Alex Bistrika

As the world's power needs grow, the demand for power from renewable resources, such as wind or solar, is increasing. One major drawback associated with these renewable resources is that the power output is dependent on environmental factors, such as cloud cover and wind speeds. This allows the...

Incorporating Computational Fluid Dynamics Methods for Quality by Design Framework for Exploring Design Space of a Fermentor

Oct 19, 2011

R. Muralikrishnan

In the Quality by Design (QbD) framework, there is a significant emphasis on the robust characterization of manufacturing processes and prospectively identifying the engineering design space that ensures product quality. Although the QbD approach is expected to bring about significant long-term...

Dissolution Testing of Prednisone and Salicylic Acid Calibrator Tablets At Different Tablet Locations

Oct 19, 2011

Piero M. Armenante

Dissolution testing is routinely carried out in the pharmaceutical industry to determine the rate of dissolution of solid dosage forms. This test is one of the several tests that pharmaceutical companies typically conduct on oral dosage formulations (e.g., tablets) to determine compliance. The USP...
