The influence of different chemical treatments on the mechanical properties of hemp fibre-filled polymer composites
… chemical treatments such as alkalization, silanization (3-aminopropyltriethoxysilane) and a maleic anhydride treatment. The effectiveness of the chemical treatments was assessed by means of XRD, FTIR and TGA. Density measurements of as-received yarns (1.42-1.45 g cm-3 ) were within the …

Corrosion and corrosion suppression on n-type gallium arsenide semiconductor liquid-junction solar cells
… Two protecting processes have been utilized. Silanization and electrochemical polymerization of divinylbenzene and phenol were used to deposit non-electroactive layers on the electrode surface. The polyphenylene oxide coating partially suppressed corrosion in acid electrolytes. However, the …

USE AND MACRO-MOLECULAR STRUCTURE OF SILICA POLYAMINE COMPOSITES
… alignment to the incident wave and varying silanization protocols were examined using the analogues. Macro-molecular structure and symmetry of the slide analogues and composites were examined via coordination of two carbonyl compounds, Ru(TFA)3CO3 and Mo(CO)3(C2H5CN)3. The project succeeded …

Methanol conversion to olefins and propene oligomerization over modified SAPO-34 and dealuminated mordenite
… of this material. These modifications were : (i) Silanization - in order to neutralize the acidity on the external surface of the crystallites and hence reduce pore-mouth blockage by coke species on the crystallite external surface; (ii) Steaming - to investigate the effect of more severe …

Self-Assembled Monolayers As Models For Silica
… for silylated SAMs of 1 and 2 indicated facile silanization of the surface hydroxides. RAIRS spectra were also obtained for the functionalized SAMs. Silylated SAMs prepared from 1, 2, and 3 are currently under investigation as models for silica-immobilized metallocene olefin polymerization …

Surface Characteristics of Silica Polyamine Composites
… Composite surface modifications such as the silanization step of SPC synthesis are shown to affect alkaline stability. Increasing surface group bulkiness and hydrophobicity circumstantially increased material stability. Anisotropy calculations utilizing solid-state CPMAS NMR spinning side …

Bonding properties of innovative CAD-CAM composite biomaterials for dental prostheses
… with alumina particles sandblasting followed by silanization (Monobond Plus, Ivoclar Vivadent). All specimens were bonded using Variolink DC (Ivoclar Vivadent) resin cement and submitted to thermocycling aging (10000 cycles). The interfacial toughness was measured using the Notchless Triangular …

The effects of surface functionalization on rheology, structure and transport properties of nanocomposites
… of the composites at the highest levels of silanization and observe shear thinning behavior that is unlike what is universally seen for hard spheres. For the entangled melts, a yield stress is observed for the silanized particles that is absent in the case of the bare particles and there is …

Chemistry of Nanoscale Solids and Organic Matter in Sustainable Water Management Systems
… the excellent hydrophobicity achieved by fluoro-silanization gave the membrane great wetting resistance and high salt rejection. More importantly, the robustness of the membrane, stemming from the excellent underwater adhesion of the PDA, made it an outstanding candidate for real-world …
