This work studied the fractionation of sugarcane bagasse via Organosolv treatment using isopropanol/water in presence Raney-Ni and molybdenum carbide catalysts (Bulk Mo 2 C supported on activated carbon (AC) or Al O 3 ). The degree delignification, bio-oil solid residue composition depended type catalyst. A partial extraction hemicellulose occurred followed by depolymerization, resulting a prod...
A simple process to achieve patterned silica films is described. The patterning of the catalyst poly-L-lysine via photolithography and liftoff enables the spatial and geometrical control of silicification. Microscopy and chemical characterization demonstrate that this process enables consistent patterning of silica with 10 mm resolution in a variety of geometries. In addition, the spatial and g...
Cascade synthetic pathways, which allow multi-step conversions to take place in one reaction vessel, are crucial for the development of biomimetic, highly efficient new methods of chemical synthesis. Theoretically, the complexity introduced by combining processes could lead to an improvement of the overall process; however, it is the current general belief that it is more efficient to run proce...
Candida Antarctica lipase B (CALB) is a well-known enzyme, especially because of its promiscuous activity. Due to its properties, CALB was widely used as a benchmark for designing new catalysts for important organic reactions. The active site of CALB is very similar to that of soluble epoxide hydrolase (sEH) formed by a nucleophile-histidine-acid catalytic triad and an oxyanion hole typical for...
Introduction: Air pollution is now recognized as an important environmental and health concern. Biological control processes, due to their durable, cost-effective and eco-friendly, have become a good alternative to physic-chemical methods. Biotechnology is based on the activity of microorganisms. The aim of this study was to compare the capability of Pseudomonas Putida PTCC 1694 (bacteria) and...
In this study, biodiesel was produced from underutilized kariya oilseed using ethanol in the presence of pod-husks bio-catalyst. The oil used extracted through soxhlet solvent extraction approach. Transesterification seed investigated Central Composite Design (CCD) Response surface methodology. Process factors such as reaction temperature (65, 70, and 85oC), time (2, 3, 4 h), ethanol/kariya mol...
