Introduction: Laboratory mixtures and spectral parameters were created to better characterize and detect kaolinite in the Mawrth Vallis region of Mars where Al-phyllosilicates, including kaolinite and montmorillonite, have been detected. We have prepared laboratory mixtures of the phyllosilicate minerals montmorillonite with kaolinite in seven intervals to(More)
Solid-state shear pulverization (SSSP) is a unique processing technique for mechanochemical modification of polymers, compatibilization of polymer blends, and exfoliation and dispersion of fillers in polymer nanocom-posites. A systematic parametric study of the SSSP technique is conducted to elucidate the detailed mechanism of the process and establish the(More)
Hyperspectral near-infrared scenes have been simulated to analyze the contributions of surface minerals, atmosphere and sensor noise on images of Mars. Modeling the remote sensing process creates a means for independent analysis of the influence of the environment and instruments on detection accuracy of the surface composition. The system models surface(More)
Enzymic hydrolysis has potential for upgrading a range of waste materials from the meat industry. The effects of the reaction variables pH, time, temperature, enzyme concentration and rumen concentration on the solubilisation of rumen by Alcalase have been determined. Reaction progress curves showed rapid initial rates followed by a gradual decline in rate.(More)
