Phosphate adsorption on aluminum-impregnated mesoporous silicates: surface and behavior of adsorbents
(American Chemical Society, 2004)Phosphorus from excess fertilizers and detergents ends up washing into lakes, creeks, and rivers. This overabundance of phosphorus causes excessive aquatic plant and algae growth and depletes the dissolved oxygen supply ... -
Pretreatment of wheat straw using combined wet oxidation and alkaline hydrolysis resulting in convertible cellulose and hemicellulose
(John Wiley & Sons Inc., 1996)The wet oxidation process of wheat straw has been studied as a pretreatment method to attain our main goal: To break down cellulose to glucose enzymatic, and secondly, to dissolve hemicellulose (e.g., for fermentation) ... -
Proteins in Mesoporous Silicates
(Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim, 2008)Mesoporous silicates (MPS) have an ordered pore structure with dimensions comparable to many biological molecules. They have been extensively explored as supports for proteins and enzymes in biocatalytic applications. ... -
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 ...
