Liquid Membrane Immobilized in Durable Inorganic Matrix for CO2 Separation

Nov 12, 2009
Jian Zhang
In this work, we will report a new liquid/inorganic membrane product concept for CO2 separation. A liquid fluid of selective CO2 absorption properties is immobilized in a thin, inorganic substrate sheet (20~50um) of graded pore structures. CO2 selectively absorbs into the liquid fluid in the feed...

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 +...

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.

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...
