Analytical Characterization:


Development of Protective Sol-gel Coating for Process Sensors:

Guozhong Cao, Materials Science and Engineering, and Brian J. Marquardt, Applied Physics Laboratory, UW


Project Summary:  Our primary goal is to engineer protective sol-gel based coatings for optical sensors that have strong adherence, high gas permeability, strong durability, and high chemical inertness.  This will be achieved by designing, developing, and optimizing new sol-gel coatings that are comprised of organically modified silanes and other metal alkoxides.  These protective sensor coatings will finally be evaluated in industrially relevant chemical systems in order to assess their protective efficacy.

Revolutionary Sensor to Measure in Real Time Progress of Enzymatic Hydrolysis for Production of Biofuels and Biochemicals from Lignocellulosic Biomass:                                                                       

Renata Bura and Rick Gustafson, Forest Resources, and Brian J. Marquardt, APL, UW


Project Summary: Future biorefineries will require new sensors and control systems to measure, in real time, the progress of hydrolysis and fermentation to be viable.  The overarching goal of this research is to develop and apply sensors for enzymatic hydrolysis of Lignocellulosic biomass to sugars to expand fundamental understanding of limitations governing saccharification process with the ultimate goal to overcome these limitations.  We propose to create viable biorefineries with the development of new sensors, control systems, and separation techniques.  The synergy between these developments allow for 1) use of Raman spectroscopy to assess membrane performance, 2) assess solid phase conversion during hydrolysis of biomass, and 3) rapid assessment of bioconversion of candidate feedstocks.
