Fuel ethanol production is one of the fastest growing segments in American agriculture. Currently, there are 83 ethanol plants in production, with an additional 16 ethanol plants under construction. These ethanol plants have production capacity of 4.3 billion gallons of ethanol per year (Renewable Fuels Association, December, 2004). Approximately 40% of fuel ethanol is produced by wet-mills, an...

In this report, hierarchical self-organization of poly(tert-butyl acrylate) (PtBA) brushand mixed PtBA/ polystyrene (PS) brush-grafted silica nanoparticles (NPs) in PtBA-b-PS block copolymer and PtBA/PS polymer blend matrices having different molecular weights was investigated using transmission electron microscopy (TEM). Driven by the entropic interactions between the brushes and the polymer m...

Poly (vinyl alcohol)-chitosan blend films were prepared by casting the respective polymer solutions. The glutaraldehyde was used as a cross-linking agent. A series of PVA-chitosan blends were prepared by varying the ratio of the constituents. Mechanical and physical properties of blended films such as tensile properties in the dry and wet states, water uptake, surface tension and contact angle ...

Nanocomposites films of (polymer blend-ceramics) were prepared from (PVA-PAA) blend and (PVA-PAA) blend doped with niobium carbide nanoparticles for humidity sensors have low cost, easy fabrication, high sensitivity, lightweight and high corrosion resistance. The structural, electrical and optical properties of (PVA-PAA-NbC) nanocomposites have been studied. The D.C electrical properties of (PV...

The facility is located in Colorado Springs and consists of three BART-eligible dry-bottom, wallfired boilers (Units 5, 6, and 7). These boilers fire a variety of coal types, including coal from the southern Powder River Basin, ColoWyo coal (from northwestern Colorado), 20-Mile Foidel Creek coal (northwestern Colorado), and West Elk coal (western Colorado). Due to equipment limitations, these b...

The present research consisted of producing 3 types of powdered concentrates: the dairy, the egg and the dairy-egg (produced from a blend of raw liquid milk and liquid eggs). The dairy-egg powder was produced in order to facilitate formulation of dry food mixes. Powders were vacuumpackaged and packaged in air atmosphere and stored for 24 months. Changes in contents of selected oxysterols (deter...
