Mesoporous silicas with tunable morphology for the immobilization of laccase.
Siliceous ordered mesoporous materials (OMM) are gaining interest as supports for enzyme immobilization due to their uniform pore size, large surface area, tunable pore network and the introduction of organic components to mesoporous structure. We used SBA-15 type silica materials, which exhibit a regular 2D hexagonal packing of cylindrical mesopores of uniform size, for non-covalent immobiliza...

15 صفحه اولStudies of water and ice in hydrophilic and hydrophobic mesoporous silicas: pore characterisation and phase transformations.
A study has been made as a function of temperature of the phase transformation of water and ice in two samples of mesoporous silica gel with pore diameters of approximately 50 A. One sample was modified by coating with a layer of trimethylchlorosilane, giving a predominantly hydrophobic internal surface, whereas the unmodified sample has a hydrophilic interface. The pore structure was character...
متن کاملIn-situ-SANS Investigations of C5F12 Condensation in Mesoporous Silicas with a Hierarchical Pore Structure
1. Introduction The condensation of liquids from the gas phase and the pore emptying mechanism in mesoporous frameworks (pore size 2 – 50 nm) represents an important scientific issue owing both to the significant industrial relevance (catalysis, separation process, etc.), but also to its importance for the fundamental understanding of the behavior of fluids in confined space. In general, the fi...
متن کاملAssessment of ordered and complementary pore volumes in polymer-templated mesoporous silicas and organosilicas.
A method to determine the volumes of ordered mesopores and complementary small pores in polymer-templated ordered mesoporous silicas and organosilicas is proposed on the basis of the existing relation between the pore width and unit cell values obtained by the XRD structure modeling and the adsorption pore volume.
