abstract statement of problem: mechanical strength and durability of dental composites are the main topics studied in this field of science today. this study examined fumed silica-based composite as a strong and durable restorative material through flexural and cycling test methods. objectives: the purpose of this study was to evaluate the effect of silanization, ageing, cycling and hybridi...
Abstract Objective Incorporating silane-coupling agent into universal adhesives (UAs) to simplify adhesive luting of glass-ceramic restorations appeared ineffective due silane’s instability in an acidic aqueous solution. This study aimed evaluate new silane technology added experimental UA be bonded glass ceramics without separate prior silanization. Methods Combined technology, consisting 3-(a...
The use of tantalum as biomaterial for orthopedic applications is gaining considerable attention in the clinical practice because it presents an excellent chemical stability, body fluid resistance, biocompatibility, and it is more osteoconductive than titanium or cobalt-chromium alloys. Nonetheless, metallic biomaterials are commonly bioinert and may not provide fast and long-lasting interactio...
Objective: Repair of an indirect restoration is usually preferred over its replacement. This study aimed to evaluate the effect of silane in different surface preparation techniques on the bond strength of direct to indirect composite resin. Methods: For this in vitro experimental study, 48 indirect composite cubes were fabricated, divided into 4 groups of 12 and subjected to the following ...
Thin hafnium oxide layers deposited by an atomic layer deposition system were investigated as the sensing membrane of the electrolyte-insulator-semiconductor structure. Moreover, a post-remote NH3 plasma treatment was proposed to replace the complicated silanization procedure for enzyme immobilization. Compared to conventional methods using chemical procedures, remote NH3 plasma treatment reduc...

According to the assumptions of European Union, by 2050 it is planned achieve climate neutrality. For this purpose, a document called “European Green Deal” was established, which set policies Commission. One circular economy that takes into account use waste in subsequent production cycles. In order meet latest trends environmentally friendly materials and building materials, composites rigid p...
