“…15 In addition, the high concentrations of silane can interfere with oligomer formation in the process of siloxane formation in silane, thus compromising the adhesion of silanes to inorganic matrices. 16 The two products employed in this research also contained solvent. The concentration of silane in a product is not considered to be the only major factor in the activation and condensation processes of silane.…”

Background: Damage to porcelain restorations such as fractures requires a repair that can be performed either directly or indirectly. Direct repair involves directly performing restoration of fractured porcelain with a composite resin application. This technique has more advantages than indirect repair because it requires no laboratory work and can be completed during a single visit. Silane, on the other hand, has been widely used and is reported to increase porcelain and composite resin attachments during the direct repair process. Purpose: This study aimed to determine the differences in shear bond strength between porcelain and composite resin during the administering of 4% and 19.81% silane. Methods: 27 porcelain samples were divided into three groups, namely: Group A - 4% silane, Group B - 19.81% silane and Group C - no silane, prior to the application of composite resin. Each sample was tested for shear bond strength by means of Autograph and fracture analysis performed through stereomicroscope and scanning electron microscope tests. Data analysis was subsequently performed using an ANOVA test. Results: There was a significant difference between the three groups with p=0.000 (p<0.005). The lowest bond strength was found in the group without silane, while the highest was in the group with 4% silane (p<0.005). Conclusion: The use of 4% silane can produce the highest shear bond strength of porcelain and resin composite.

A new copolymer consisting of double four ring (D4R) silicate units linked by dimethylsilicone monomer referred to as polyoligosiloxysilicone number one (PSS-1) was synthesized. The D4R building unit is provided by hexamethyleneimine cyclosilicate hydrate crystals, which were dehydrated and reacted with dichlorodimethylsilane. The local structure of D4R silicate units and dimethyl silicone monomers was revealed by multidimensional solid-state NMR, FTIR and modeling. On average, D4R silicate units have 6.8 silicone linkages. Evidence for preferential unidirectional growth and chain ordering within the PSS-1 copolymer was provided by STEM and TEM. The structure of PSS-1 copolymer consists of twisted columns of D4R silicate units with or without cross-linking. Both models are consistent with the spectroscopic, microscopic and physical properties. PSS-1 chains are predicted to be mechanically strong compared to silicones such as PDMS, yet more flexible than rigid silica materials such as zeolites.

“…In addition, the possibility of combining their intrinsic properties with new functionalities through the anchoring of appropriate molecular systems14–16 has allowed the development of multifunctional materials, which provide a basis for a broad range of applications 17. Depending on the nature of the inorganic surface, different families of functional molecules having silane,18,19 thiol20,21 and carboxylic22 moieties as anchoring groups have been widely used to modify inorganic materials. In the past years, organophosphorus compounds have attracted growing interest and were proven to be efficient alternatives to the more often adopted silane and carboxylic compounds for the functionalization of metal oxide surfaces 23,24…”

Spatially Confined Functionalization of Transparent NiO Thin Films with a Luminescent (1,10‐Phenanthroline)tris(2‐thenoyltrifluoroacetonato)europium Monolayer

Transparent MOCVD‐grown NiO films have been functionalized with the luminescent (1,10‐phenanthroline)tris(2‐thenoyltrifluoroacetonato)europium(III) complex [Eu(TTA)3phen] by combining sputter activation with a solution synthetic route. To introduce the Eu complex only on selected regions, some areas of the NiO surface were activated by Ar+ ion sputtering and then functionalized with 3‐phosphonopropionic acid (CPPA) followed by the anchoring of Eu(TTA)3phen through a ligand‐exchange reaction between β‐diketonato ligands and the carboxylic groups of CPPA. The functionalized material was characterized by X‐ray photoelectron, UV/Vis and luminescence spectroscopy. XPS measurements indicated that CPPA prefunctionalization and, in turn, the Eu(TTA)3phen anchoring occurs only on the sputter‐activated region, while no anchoring takes place on the unactivated surface. The optical properties of the Eu(TTA)3phen–NiO system were evaluated by UV/Vis and luminescence spectroscopy.
