AB  - Polimerne smole na bazi akrilata dobijene iz Bis-GMA (Bisfenol A glicidmetakrilat), koji je pogodan za fotopolimerizaciju, koriste se u stomatologiji za različite namene zbog lakoće nanošenja i mogućnosti da se utiče na njihova svojstva dodavanjem ojačanja različitog oblika i hemijskog sastava. Sintetisano je ojačanje u formi čestica na bazi dvostrukih slojevitih hidroksida magnezijuma i aluminijuma (MgAlLDH-Layered Double Hidroxides) nataloženih na silicijum dioksidu dobijenom iz ljuski pirinča. Kao podloge korišćene su metalna legura na bazi hroma i molibdena za primenu u stomatologiji i staklo u formi podloga za mikroskopske preparate. Adhezivna svojstva kompozita su bitna sa aspekta njihove primene. Adhezivna svojstva materijala su određena na osnovu merenja mikrotvrdoće kompozita i to primenom različitih opterećenja kako bi se procenio parametar adhezije koji pokazuje uticaj prevlake na podlogu. Upoređeno je kako se vezuje čista matrica od fotopolimerizujućeg akrilata sa podlogom od stomatološke legure sa vezivanjem za staklenu podlogu. Potom je upoređeno kako se vezuju kompozitni materijali na obe podloge. Adhezija je određena i na osnovu promene ugla kvašenja između kompozita i rezultati su upoređeni sa rezultatima mikroindentacije. Pokazalo se da dodatak kompozitnih čestica kao ojačanja u matricu od akrilata povećava adhezivna svojstva kompozita u odnosu na čistu matricu i da se ostvaruje bolja adhezija između kompozita i metalne podloge nego između kompozita i staklene podloge.
AB  - Polymer resins based on acrylates obtained from Bis-GMA (Bisphenol A glycide methacrylate), which is suitable for photopolymerization, are used in dentistry for various purposes due to the ease of application and the possibility to influence their properties by adding reinforcements of different shapes, crystal structure and chemical compositions. Reinforcement in the form of particles based on MgAlLDH (layered double hydroxide) deposited on silica obtained from rice husks on two substrates. A metal base and glass were used. The adhesive properties are important in order to see the possibility of using these materials in applications. In order to measure the adhesive properties of the material, the composite microhardness measurement method is used by applying different loads in order to evaluate the adhesion parameter that shows the effect of the coating on the substrate. It was compared to how a pure photopolymerizing acrylate matrix bonds with a chromium-based dental alloy substrate that is used in the production of different parts of dentures by bonding to a glass substrate. Then, it was compared how composite materials are bonded to both substrates. Adhesion was monitored through the change in wetting angle between the composites, and the results were compared with the results of microindentation. It was shown that the addition of composite particles increases the adhesive properties of the composite compared to the pure matrix and that better adhesion is achieved between the composite and the metal substrate than between the composite and the glass substrate.

AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modifiedplant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained fromwaste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the producedsilica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigatethe mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization ofcomposite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) andmeasurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles withvinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and loadfor comparison of measurements between different composite materials and to enable the choice of the material in terms ofoptimization of the quality of reinforcement and quality of interphase determined by surface modification.

AB  - Electrochemically deposited nickel coatings fromsulfamate baths without/with lab-made biosilica (SiO2) particles onthe Si(100) substrate were produced. Different galvanostaticregimes were used: direct current (DC), pulse current (PC), andpulse-reverse current (PRC) regimes. The phase structure of thesynthesized silica nanoparticles from rice husks was obtained usingXRD and FE-SEM. The MMC-Ni/SiO2 and free Ni coatings werecharacterized using FE-SEM, AFM, the micro indentation Vickerstechnique, and the drop sessile method in order to investigatestructure, roughness, microhardness, and wettability. The optimaldeposition parameters were obtained with an emphasis on theirpotential application as micro mounting coatings.
