Production of Zein From Dry Milled Corn by Solvent Extraction and Ultrafiltration
The process developed here can be easily integrated into any corn processing facility, especially dry-grind ethanol plants. The solvent extraction step involves only mixing and a filtration/centrifugation step. The filtered extract, after further treatment if necessary to improve protein purity, …

Drying Oils Treated by Irradiation as Coatings for Biobased Films
Biobased films are potential food packaging materials. However, their performance with respect to water and gas barrier properties is inferior to current packaging products on market. Drying oils are promising as film coatings to improve water barrier properties of protein-based films. Drying oils …

Preparation of Zein-Based Biodegradable Materials and Investigation of Their Physical Properties
Plasticization was improved by dissolving zein and fatty acids in warm aqueous alcohol solutions. Resins were obtained through precipitation and kneading treatments. Inclusion of palmitic and stearic acid in the formulation resulted in harder resins that were suited for rolling into sheets; whereas …

Design of Improved Polyester Dielectric Insulators for Electronic Packaging
First, the foaming methods used to lower the dielectric constant of the copolyester thermoset to 2.5 $\rm (25\sp\circ C,$ 1 kHz) are described. Second, the nature of the increase in melting temperature of the liquid crystalline copolyesters upon annealing near their original melting temperature to …

Models for Yield Estimation of Multichip Module Ceramic Substrates
We present improved yield models that can be used for a broader range of printed patterns. We also enhance the defect geometry models that are commonly used today. We introduce a defect geometry model that is based on the physical process of defect formation. Our defect geometry model employs …

Novel Methodologies and Measurement Software for Transistor Amplifier Synthesis in Planar Coupled -Transmission Lines
This thesis concerns the synthesis of active devices in coupled-microstrip and coupled-coplanar technology. We first discuss several aspects of multiconductor transmission line (MTL) theory, including longitudinal dependencies of immittance functions. We next describe a frequency domain normal mode …

Production of Zein From Dry Milled Corn by Solvent Extraction and Ultrafiltration
This research focused on developing a process for the production of low cost zein from corn using a combination of solvent extraction and membrane technology. Extraction of zein from dry milled whole corn was optimum with 70% ethanol at 50°C using a solvent-to-solids ratio of 6 ml ethanol per g …
