Feed-Forward Process Control Strategy for Pharmaceutical Tablet Development

Nov 11, 2009
Koji Muteki
A feed-forward process control strategy which can compensate for the effect of raw material lot-to-lot variability on final tablet attributes in pharmaceutical tablet development is presented. The approach involves building PLS (partial least squares) models that combine raw material attributes and...

Battery Design for Large Lithium and Zinc Batteries

Nov 11, 2009
G. J. Suppes
A battery design is being evaluated which is particularly useful for larger battery applications such as in PHEV and electrical grid applications. Preliminary studies validate the approach. Parametric studies are discussed which define performance curve.

Solar Thermal H2O Splitting Via Cobalt Ferrite Based Thermochemical Cycles

Nov 11, 2009
Jonathan Scheffe
Spinel ferrites of the form MxFe3-xO4, where M generally represents Ni, Zn, Co, Mn, Fe or other transition metals, have been shown to be capable of splitting water to produce H2 using solar energy according to the two step cycle shown below: MxFe3-xO4 xMO + (3-x)FeO + 0.5 O2 (1) xMO + (3-x)FeO +...

Application of Modeling to Scale-up Liquid Mixing Processes

Nov 11, 2009
Venkat R. Koganti
Scale-up of liquid mixing is usually done empirically without considering the several factors like dissolution theory, equipment differences between scales and so on. In this work we present a systematic way to scale-up liquid mixing processes utilizing both Design of Experiment (DoE) approach to...

Growth Kinetic Study of Chlorella Vulgaris

Nov 11, 2009
Jinsoo Kim
Algae are simple autotrophic organisms that produce complex organic compounds from simple inorganic molecules such as carbon dioxide using energy from light or inorganic chemical reactions. These complex organics include a substantial amount of triacylglycerol which can be readily converted into...
