Porosity and Surface Properites of SBA-15 with Grafted PNIPAAM: A Water Sorption Calorimetry Study

Mesoporous silica SBA-15 was modified in a three-step process to obtain a material with poly-N-isopropylacrylamide (PNIPAAM) grafted onto the inner pore surface. Water sorption calorimetry was implemented to characterize the materials obtained after each step regarding the porosity and surface properties. The modification process was carried out by (i) increasing the number of surface silanol g...

Nanoporous composites prepared by a combination of SBA-15 with Mg–Al mixed oxides. Water vapor sorption properties

This work presents two easy ways for preparing nanostructured mesoporous composites by interconnecting and combining SBA-15 with mixed oxides derived from a calcined Mg-Al hydrotalcite. Two different Mg-Al hydrotalcite addition procedures were implemented, either after or during the SBA-15 synthesis (in situ method). The first procedure, i.e., the post-synthesis method, produces a composite mat...

A THERMO-RESPONSIVE PNIPAAm-GRAFTED-PDMS SURFACE USED FOR CELL CULTURE IN MICROFLUIDIC CHANNELS

A thermo-responsive PNIPAAm-grafted-PDMS (PNIPAAm-g-PDMS) surface was used for cell culture. Cos7 cells could adhere to the PNIPAAm-g-PDMS surface and proliferated therein at 37 C. The cultured cells could detach from the surface at room temperature without trypsin digestion. The viability of cells harvested from the PNIPAAm-g-PDMS surface via lowering temperature was higher than that of cells ...

Synthesis, characterization, and catalytic performance of highly dispersed vanadium grafted SBA-15 catalyst

Vanadium oxide grafted on mesoporous silica SBA-15 has been synthesized using a controlled grafting process. Its structure has been thoroughly investigated using different characterization techniques, including N2-physisorption, X-ray diffraction, transmission electron microscopy (TEM), Raman spectroscopy, H2 temperature-programmed reduction, X-ray absorption near-edge structure (XANES), and ex...
