In order to prepare basalt fibers-reinforced cement-based mortars with higher compatibility between reinforcement and matrix, fibers new surface treatments (sizing) were studied looking for enhanced interaction at the interphase cement matrix. As-received, calcinated, activated silanized (by three silane aqueous solutions: i) ?-aminopropyltriethoxysilane, APTES; ii) ?-aminopropylmethyldiethoxys...

In this study, photosensitizer conjugated iron oxide nanoparticles were strategically designed and prepared for simultaneous PDT and dual-mode fluorescence/MR imaging. The MRI contrast agent Fe3O4 was modified by APTES to functionalize the surface and further to link with heparin-pheophorbide-A conjugates.

H3PW12O40 (PW12) was immobilized over mesoporous alumina through the reaction of mesoporous alumina functionalized 3-aminopropyl triethoxy silane (3-APTES) and PW12. The surface properties of the functionalized nanocomposite was analyzed by a series of characterization techniques like elemental analysis, FTIR and XRD. XRD and adsorption–desorption analysis shows that the mesostructure of silica...

Field Effect Transistors (FETs) have led the progress of applications measuring acidity in aqueous solutions thanks to their accuracy, ease miniaturization and capacity multiplexing. The signal-to-noise ratio linearity sensors are two most relevant figures merit that can facilitate improvements these devices. In this work we present functionalization with aminopropyltriethoxysilane (APTES) a pr...

In this project, a prompt, efficient, and effective method for Cd2+ ions extraction from different food water samples using magnetic dispersion-based solid phase by functionalized iron oxide nanoparticles was proposed. Iron were synthesized through the co-precipitation followed functionalization with tetraethyl orthosilicate (TEOS) 3-aminopropyl silane (APTES) to obtain Fe3O4@SiO2@APTES. This c...

A wood modification with MA and APTES was achieved which enabled an increased MOF loading of MIL-53(Al) ZIF-8 for a potential application the MOF@wood composite in continuous filtration catalysis.

The present work focuses on the synthesis of Fe 3 O 4 magnetite core@shell type nanoparticles modified with three types ligands: Magnetite activated carbon (MAC), silica (tetraethoxysilane, TEOS, and 3-aminopropyltriethoxysilane, APTES) (MTA) silica, APTES humic acids (MTAH). MTAH sample shows greater porosity in comparison to MTA, MAC samples. band gap is 4.08 eV, which higher than MTA (2.92 e...
