Model based cross-directional monitoring and control of plastic film thickness
… monitoring, and cross-directional control of a plastic film manufacturing process operated by DuPont Teijin Films Ltd. The developed model is of high dimension and built using the first-principles of chemical and mechanical engineering, such as equations for mass transfer, heat transfer, and the …

Design of a compact, lightweight, and low-cost solar concentrator
… achieving these design parameters was to use the plastic film Mylar in its aluminized form to create a paraboloid serving as a solar concentrator. The scope of design was limited to designing and prototyping the solar concentrator, and neglecting to design and prototype the container in which it …

Abrasive grit application for integrated weed and nitrogen management in organic vegetable cropping systems
… treatments (straw mulch, biodegradable plastic film, polyethylene plastic film, and a bare soil control) were replicated four times in an organic pepper cropping system near Urbana, IL in 2015 and 2016. Soybean meal, turkey litter, and walnut shell grits, used in conjunction with plastic …

Sub-Tg̳, solid-state, plasticity-induced bonding of polymeric films and continuous forming
… discovery of a new phenomenon of solid-state, plasticity-induced bonding at temperatures well below Tg which take on the order of a second, by subjecting amorphous polymers to active plastic deformation. In spite of the glassy regime, the bulk plastic deformation triggers requisite molecular …

Primary Driving Force in Wood Vacuum Drying
… specimens were coated with wax, wrapped in the plastic film and inserted into a rubber tube to prevent the moisture loss from the side surfaces during drying. The specimen size was 1×1×10 inches. Red oak and white oak were sealed and dried in both cyclic and continuous vacuum drying. …

Implications of Microorganisms in Future Crewed Missions to Mars
… products required for daily routine, such as plastics. In this work, a two-step system was developed to produce bioplastics by microbial culture. C. reinhardtii was cultured to create biomass, which was processed to produce 16.8 g/100g ± 0.67 of starch as feedstock with a productivity of 2.79 …
