Recombination activity of contaminated dislocations in silicon: a model describing electron-beam-induced current contrast behavior
(The American Physical Society, 2001)Existing experimental data give many evidences that the recombination rate of minority charge carriers at dislocations in silicon depends strongly on dislocation decoration by transition metal impurities. Here, we present ... -
The role that lignocellulosic feedstocks and various biorefining technologies can play in meeting Ireland's biofuel targets
(Society of Chemical Industry and John Wiley & Sons, Ltd, 2009-04)This paper considers the contribution that biorefi neries, through the production of second-generation biofuels from lignocellulosic feedstocks, can make in the Republic of Ireland to the mandated 10% transport biofuel ... -
Silica gel from rice hull ash: preparation and characterization
(American Association of Cereal Chemists, Inc., 1998-07)Rice hulls, a waste coproduct of the rice industry, is composed of 20% silica. The objectives of this study were to develop a method to recover silica from rice hull ash and produce silica gel, and to determine the physical ... -
Vanillin as a product of ferulic acid biotransformation by the white-rot fungus Pycnoporus cinnabarinus I-937: identification of metabolic pathways
(Elsevier Science B.V., 1994)Ferulic acid metabolism was studied in cultures of the white-rot fungus Pycnoporus cinnabarinus I-937. After 6 days of growth, during the secondary metabolism of the fungus, the concentration of vanillin in the culture ...
