Introduction: Tissue engineering approach using the combination of stem cells and nanofibrous scaffolds has attracted the interest of research community for regeneration applications. Materials and Methods: In this study, PANi/PCL/Gel composite nanofibrous scaffold was fabricated by electrospinning. Plasma treatment technique was used for the surface modification of nanofibers. Contact angle...
A universal surface modification for glass and fused silica microchannels has been developed. The method allows for the formation of catalytic surfaces within a channel after channel closure. These surfaces can contain ligand systems or functionalities of choice covalently attached to the robust surface modification. The utility of the system is demonstrated by the formation of Jacobsen and Gla...
A weak surface modification is applied to Co/SiO2 catalyst by hydrothermal treatment at 180°C for 5 h. Aluminum is introduced to Co/SiO2 catalysts during the surface modification. The effects of surface modification on Co/SiO2 catalyst are studied by changing the operating sequences of surface modification and cobalt impregnation in the catalyst preparation. Surface modification before cobalt i...
N-Methyl-Nʹ-propyltrimethoxysillylimidazolium chloride was prepared as ionic liquid (IL) containing silylating agent and then used for modification of the internal surface of SBA-15 to gain a heterogeneous ionic liquid catalyst. Subsequently, the obtained SBA-IL was characterized using various techniques, including SEM and TEM images, FT-IR, X-ray diffraction, TGA/DTA and BET ...
This paper provides an overview of how the surface properties of ferromagnetic nanoparticles dispersed in fluids is modified by natural and biocompatible polymers. Among common magnetic nanoparticles, magnetite (Fe3O4) and maghemite (g-Fe203) are popular candidates because of their biocompatibility. Natural polymeric coating materials are the most commonly used biocompatible magnetic nanopartic...
