Emissivity of patterned silicon wafers in rapid thermal processing
… on emissivity in silicon wafers in rapid thermal processing systems has been investigated. In this study, two experiments with layered and patterned silicon wafers were conducted. The main difference in the experiments is the way in which the temperature was controlled. The first …

Manufacture of aerospace-grade thermoset and thermoplastic composites via nanoengineered thermal processing
… presses (usually for thermoplastic matrices) for processing composites through conductive heat transfer are limited to a narrow range of part geometries. Direct Joule heating with carbon nanotube (CNT) film network heaters has shown significant promise to overcome these key manufacturing …

The design and engineering of a reactor test facility for thermal processing of biomass
This thesis describes the design and engineering of a pressurised biomass gasification test facility. A detailed examination of the major elements within the plant has been undertaken in relation to specification of equipment, evaluation of options and final construction. The retrospective project …

MRI temperature mapping and finite element modeling of heat transfer in carrot particulates undergoing thermal processing
A series of experiments were conducted to test the feasibility and accuracy of using T$\sb1$ weighted magnetic resonance imaging to measure the temperature inside foods during heating. First, a steady state temperature gradient was applied to a model food gel. The T$\sb1$ temperature dependence for …

The Effect of Thermal Processing Schedules and Unit Operations on the Quality of Blue Crab (Callinectes sapidus) Meat
The effects of initial thermal processing, plant sanitation, and employee habits on the microbiological quality of blue crab (Callinectes sapidus) meat were determined in a commercial crab processing facility. Thermal processing was evaluated at 5, 7, and 8 minutes at 250ï °F for the destruction of …
