Dr. Junyong Zhu, USDA forest Service, Forest products Laboratory, Madison, WI, USA will present "Converting Woody Biomass to Biofuel and BionanomaterialsConverting Woody Biomass to Biofuel and Bionanomaterials".

The concept of producing lignocellulosic biofuel, bioproducts, and chemicals through a biorefinery using lignocelluloses has been around for about a century. However current technologies for commercial scale production are not economically viable. At the Forest Products Lab, we are devoted to develop the science and engineering for sustainable and efficient utilization of our forest resources through the forest biorefinery concept. This presentation will provide an overview of several research activities in my laboratory. My presentation will focus on addressing practical issues related to commercial applications, such as energy efficiency in pretreatment, high solids enzymatic saccharification and fermentation, water consumption in biorefinery operations, as well as improve enzymatic saccharification efficiencies to reduce enzyme loadings. The results from a series of our publications will be assembled in the presentation. Finally, I will touch the topic of integrated production of sugar/biofuel with nanocellulose as a high value product to improve the biorefinery economics. The underlining fundamentals will also be discussed, such as the “combined hydrolysis factor (CHF)” developed based on the kinetics of wood hydrolysis for process scale up, and a cellulase binding model for understanding nonspecific cellulase binding andcellulase recycling.

Please join us for a graduate seminar titled “The Biology of the Weapons of Sexual Selection in Scarab Beetles.”  This seminar will be presented by Laura Corley Lavine, PhD, Department of Entomology at Washington State University.   The seminar will be presented on Friday, April 27, 2012 at 4:00pm in FSHN T101.

The morphological diversity of insects is one of the most striking Scarab Beetlephenomena in biology. Evolutionary modifications to the relative sizes of body parts are responsible for a vast range of body forms. Traits with exaggerated proportions such as the “weapons” of beetles have evolved multiple times among several scarab lineages. Sexual selection has shaped the evolution of male phenotypes in many species in which only the males develop weapons that they use to combat rival males for access to females. As with other sexually-selected traits, many beetle weapons are phenotypically plastic resulting from differences in the nutritional environment experienced by growing larvae. What remains unknown however, are the mechanisms that are responsible for coupling nutrition with the disproportionate growth of beetle weapons. I will discuss this phenomenon as well as some other interesting facts about using these beetles as potential spying devices.

Water and Agriculture in the Pacific Northwest”.  The seminar was presented by Dr. Troy Peters, Ph.D., Extension Irrigation Specialist at the Washington State University Irrigated Agriculture Research and Extension Center in Prosser, WA  on Friday, February 17, 2012 at 4pm in FSHN 101T. 

This lecture will introduce students to the land grant system and to extension.  It will also cover current major water issues in the Pacific Northwest and an estimate of where these issues are heading in the future.  The role that irrigation and energy plays in water issues will be discussed.

Troy Peters currently serves as the Extension Irrigation Specialist at the Washington State University Irrigated Agriculture Research and Extension Center in Prosser, WA.  Troy received his Ph.D. in irrigation engineering from Utah State University.  Following graduation he worked at the USDA-Agriculture Research Service Conservation and Production Research Laboratory in Bushland, TX for three years.  He has been with Washington State University for 6 years.  He is also a certified agricultural irrigation specialist and is a licensed professional agricultural engineer.

Some Considerations in Enzyme Activity  in  Food ( Processing )“ was presented by Joseph R. Powers, Professor, School of Food Science at Washington State University.  The seminar was presented Friday, February 10, 2012 at 4pm in FSHN T101.

An overview of enzymes causative in food quality changes  with examples from the literature will  be presented along with examples from the  School of Food Science research efforts.  The latter will include broccoli and cheese  as examples of foods in which an enzyme target needs to be inactivated and a system in which enzyme(s) play a positive role ,  respectively . 

Reputations and Neighbors: Understanding Markets for Wine”.  The seminar was presented by Dr. Jill McCluskey, Professor in the School of Economics at Washington State University,Friday, February 3rd at 4pm in FSHN 101T. 

This seminar will draw upon McCluskey’s research on collective and firm reputations with location considerations and the impact on markets, with a focus on the wine industry.  She discusses producers’ incentives to invest in quality when firms having their own private brand name also share a common name and reputation.  She shows how names and reputations nest within each other to identify producers with increasing specificity with market data.  Finally, she examines the spatial relationships among neighboring wineries with market data, including GIS data.

“Detecting Water in Food and Soil Using Dielectric Spectroscopy” by Dr. Martin Buehler,Ph.D., Decagon Devices, Inc., Pullman, Washington.  (27Jan2012)

Dielectric spectroscopy is used in many diverse fields such as microbial corrosion, polymer chemistry, medical tissue research, film thickness measurements, water content and activity in soils and foods. Measurement frequencies range over 11 orders of magnitude from microhertz to gigahertz making equipment choices challenging. Test cells for delivering EM fields to samples can take many forms: configurations can be parallel-plates, interdigitated-fingers, transmission-lines, or coaxial electrodes.

In this talk, dielectric spectroscopy will be introduced by discussing dipole polarization using the frequency dependence of the dielectric constant of water. The presentation will include test cells and their geometrical factors which are needed to convert electrical measurements into dielectric constants. Ion-dipole polarization is used to explain the effect of salinity on the dielectric constant of water. Orientation polarization is used to explain the frequency dependence of the dielectric constant of ice. Finally, glass transition measurements of polydextrose using dielectric spectroscopy are compared to results from differential scanning calorimetry.
