Topic:

One-Stage Process for Water Gas Shift in a Pd-Based Membrane Reactor

Oct 31, 2012

Efrem Curcio

The water gas shift (WGS) reaction is the upgrading stage in the cycles of hydrogen production by, for example, steam reforming of light hydrocarbons from fossil or renewable sources. This reaction limited by thermodynamics often carried out in industry to convert CO, producing more hydrogen. A WGS...

Bulk and Micro-Scale Characterization of Continuous Powder Blending Integrated with an Multi-Point in-Line NIR As a PAT Tool

Oct 31, 2012

Juan G. Osorio

Continuous manufacturing of solid pharmaceutical products has been an area of much research in the past few years. Most efforts have focused in characterizing the bulk properties and efficiency of continuous powder mixers as a function of operational and design parameters. The present study...

Modeling Phase Separating Materials in Porous Electrodes Using Non-Equilibrium Thermodynamics

Oct 31, 2012

Todd R. Ferguson

Phase separating materials are prevalent in lithium-ion batteries. Commercial lithium-ion battery anodes typically consist of graphite, a material known to go through multiple ?stages? as the filling fraction (i.e. percentage) of lithium in the material changes. Other phase separating materials,...

Fractionation of Forest Residues of Douglas-Fir for Fermentable Sugar Production by SPORL Pretreatment

Oct 31, 2012

Chao Zhang

Douglas-fir (Pseudotsuga menziesii) forest residues were physically fractionated through sieving. The bark and wood were separated for large-sized fractions (>12.7 mm) and their contents were determined. The chemical compositions of the large fractions were calculated based on the contents and...

Quantitative Analysis of Crystalline Materials in Binary Compacts Using Time Domain Spectra of THz Spectroscopy and Density Dependence

Oct 31, 2012

Md. Anik Alam

Polymorph and pseudo-polymorph systems play a major role in the pharmaceutical industry because of their potential to impact the performance of finished dosage forms. Quantitative analysis of polymorph and pseudo-polymorph is becoming increasingly important for solid oral dosage forms and...

Hybrid Li-Air Battery with Sulfuric Acid Electrolyte and Buckypaper Air Cathode

Oct 31, 2012

Yunfeng Li

Li-air battery (LAB) with aqueous-based catholyte and a water-stable lithium electrode using a LISICON-type lithium ion conducting glass ceramic membrane can eliminate the problems of Li-air battery with organic electrolytes, such as air-breathing cathode choking and degradation of Li anode. We...

Development of a Butanol Fuel Processor for Person-Portable Fuel Cell Power Systems

Oct 31, 2012

Stephen Jolly

A novel partial oxidation (POX) catalyst and butanol-to-hydrogen fuel processor sub-system concept have been developed to fill the need for person-portable power systems with high energy density for extended duration operation. The system is designed to reform isobutanol through partial oxidation...

Prediction of Post-Relaxation Radial Tensile Strength of Pharmaceutical Tablets Using At-Line Collected near Infrared Data

Oct 31, 2012

Sameer Talwar

The prediction of relaxed radial tensile strength (RTS) of pharmaceutical tablets in real-time using near infrared (NIR) spectroscopic data collected at-line was investigated. Radial tensile strength is a critical quality attribute (CQA) of tablets which may correlate to drug product performance in...

CFD Modeling of Commercial-Scale Entrained-Flow Coal Gasifiers

Oct 31, 2012

Jinliang Ma

Optimization of an advanced coal-fired integrated gasification combined cycle system requires an accurate numerical prediction of gasifier performance. Computational fluid dynamics (CFD) has been used to model the turbulent multiphase reacting flow inside commercial-scale entrained-flow coal...

Fractionation and Characterization of Lignin From Wood Biomass Using Ionic Liquid and Alkaline Ethanol Solvent

Oct 31, 2012

Yong-Chang Sun

Lignocellulosic biomass is a new source of renewable and carbon neutral materials for biofuel and bioenergy production. However, we note the recalcitrance of lignocellulosic for bioconversion. The presence of lignin is a barrier to enzymatic hydrolysis of cellulose by cellulases, as well as...

Electrochemistry and Transport Limitations of Non-Aqueous Li-Air Batteries From First-Principles

Oct 31, 2012

Venkatasubramanian Viswanathan

Li-air batteries have much higher gravimetric energy storage density compared to all other battery chemistries, and this has led to a strong interest in seeing if such batteries could be developed for powering EVs, enabling driving ranges comparable to gasoline powered automobiles. However, many...
