AB  - Magnesium ferrite (MgFe2O4) particles were synthetized by sol-gel method and used in the decolorization of the Acid Violet 109 (anthraquinone dye, AV109) water solutions' by combination of adsorption and heterogeneous Fenton process. The material's morphology and elemental analysis of the surface were revealed by Scanning electron microscopy and Energy Dispersive Spectroscopy (SEM/EDS). The X-Ray Diffraction (XRD) technique was used to analyze the crystallographic phase. In the first part of the decolorization experiment, the adsorption ability of the synthesized particles was investigated. During the adsorption study influence of pH was investigated. In the second part of the decolorization experiment, the effects of the various parameters on the Fenton process were studied such as the initial concentrations of hydrogen peroxide, dye, and magnesium ferrite particles. Influence of magnesium ferrite particles structure, pH value and reaction temperature were also investigated. The decolorization reaction was followed by UV-Visible (UV-Vis) spectrophotometry. At optimal conditions, the dye decolorization was 99.1% (55.4% by adsorption and 43.7% by the Fenton process). Both the adsorption and the Fenton process obey second-order kinetics.

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  - Acrylate polymers are used in several applications such as dentistry, medicine, and industry. The modification of their properties using the reinforcement is of key importance for the possible applications. Layered double hydroxides are materials that are easily synthesized by several techniques giving the possibility to modulate the chemical composition and morphology of the reinforcement and they consist of a divalent and a trivalent anion hydroxide and the layers can be exfoliated and thus provide a material interesting for composite reinforcement. In this paper, Mn was used as a divalent and Al as a trivalent cation. The obtained particles were used as reinforcement for the preparation of composites in 1, 3, and 5 wt% quantities and prepared samples were compared to the matrix consisting of PMMA. Physical mechanical properties of the sample having the best mechanical properties (with 3 wt% of MnAl-LDH filers) exhibited 6.38% modulus of elasticity, 27% hardness, and 10% tensile strength improved values compared to the clear PMMA matrix. Toughness was lowered in this sort of composite compared to the pure matrix. Highlights: MnAl-LDH-PMMA composites improved modulus, strength, hardness Loss of toughness is tolerable for 3 wt% reinforcement Viscoelastic properties are improved for composites compared to matrix.

AB  - U okviru predmetnog pronalaska izvedeno je istaživanje uticaja stukture poliedarnih oligo silsekvioksana (POSS) na adheziju kompozitnih filmova na metalnoj podlozi. Kompozitni filmovi se sastoje od UV polimerizovane Bisfenol A-glicidil dimetakrilata i trietilen glikol dimetakrilat (Bis-GMA/TEGDMA) matrice i reaktivne POSS strukture za poboljšanje adhezije. Kompozitni filmovi napravljeni su sa 1, 3, 5 i 10 mas. % POSS reagenasa. Adhezija je procenjena pomoću ispitivanja mikrotvrdoće metodom po Vikersu. Ugao kvašenja kompozitnih filmova metalne podloge od mesinga meren je i poređen sa parametrom adhezije koji je dobijen iz merenja mikrotvrdoće. Optička mikroskopija pokazala je fazno razdvajanje POSS reagensa koji ukazuju na meru kompatibilnosti između matrice i svake čestice. Analiziran je oblik i veličina otiska i bio je u korelaciji sa kvalitetom adhezije. Metode korišćene u ovom radu za procenu jačine i kvaliteta adhezije jasno su pokazale da je poboljšanje adhezije Bis- GMA/TEGDMA matrice i POSS reagensa koji sadrži funkcionalnu hidoksilnu i metakrilnu grupu.

abstract = "U okviru predmetnog pronalaska izvedeno je istaživanje uticaja stukture poliedarnih oligo silsekvioksana (POSS) na adheziju kompozitnih filmova na metalnoj podlozi. Kompozitni filmovi se sastoje od UV polimerizovane Bisfenol A-glicidil dimetakrilata i trietilen glikol dimetakrilat (Bis-GMA/TEGDMA) matrice i reaktivne POSS strukture za poboljšanje adhezije. Kompozitni filmovi napravljeni su sa 1, 3, 5 i 10 mas. % POSS reagenasa. Adhezija je procenjena pomoću ispitivanja mikrotvrdoće metodom po Vikersu. Ugao kvašenja kompozitnih filmova metalne podloge od mesinga meren je i poređen sa parametrom adhezije koji je dobijen iz merenja mikrotvrdoće. Optička mikroskopija pokazala je fazno razdvajanje POSS reagensa koji ukazuju na meru kompatibilnosti između matrice i svake čestice. Analiziran je oblik i veličina otiska i bio je u korelaciji sa kvalitetom adhezije. Metode korišćene u ovom radu za procenu jačine i kvaliteta adhezije jasno su pokazale da je poboljšanje adhezije Bis- GMA/TEGDMA matrice i POSS reagensa koji sadrži funkcionalnu hidoksilnu i metakrilnu grupu., Within the scope of the present invention,the effect of the structure ofpolyhedral oligomeric silsesquioxane (POSS) on the adhesion of composite filmson metal supstrate has been researched.

AB  - Organic pollutants and their residues formed after various technological processes can be found all around us (in soil, watercourses, and air). The textile wastewaters contain many hazardous substances which have carcinogenic and mutagenic effects on living organisms. The study divides into two parts; the first part is dedicated to the synthesis and characterization of catalysts, and the second part describes the decolorization of AV 109 solution by the heterogeneous Fenton process using magnesium ferrite as a catalyst. The catalysts are synthesized by the sol-gel technique and sintered at different temperatures (500, 600, and 700 °C). Scanning Electron Microscopy reveals the morphological structure of the ferrite-based catalysts, and the size and form of the used catalysts can describe using some shape factors. Elemental analysis of the supported catalyst surfaces revealed by Scanning Energy Dispersive Spectroscopy. The effect of dye's, hydrogen peroxide's and catalyst's concentrations, pH value, and type of catalyst, on dye removal by the Fenton process was studied. The change of AV 109 concentration during the decolorization was followed using the UV-Visible spectrophotometer.

AB  - One of the promising methods for wastewater treatment is adsorption. This study investigated the adsorption of anthraquinone dye Acid violet 109 from water solution using the alumina- iron oxide doped particles prepared by sol-gel method and sintered at 800 °C. The adsorbent morphology and distribution of diameter of the particles were revealed by Scanning Electron Microscopy and Energy Dispersive Spectroscopy. In the second part, the effect of initial dye's and adsorbent's concentrations and pH value on dye adsorption was studied. Also, the kinetic study of dye adsorption covers the pseudo-second-order and intra-particle diffusion. The change of AV 109 concentration during the adsorption was followed using the UV-Visible spectrophotometer. The adsorption kinetics is in accordance with the pseudo-second-order kinetics model. After 60 minutes of treatment, at the initial dye's concentration of treatment, at the initial dye's concentration of 50 mg dm–3 using the alumina-iron doped particles adsorption efficiency was 51.3% and the value of adsorption capacity is 2.64 mg g –1. The adsorption rate was 0.122 g mg–1 min–1.

AB  - This study presents the impact properties of the new form of hybrid thermoplastic composites. The Kolon fabrics were impregnated with the 10 wt% poly (vinyl butyral) (PVB)/ethanol solution with the addition of silica (SiO2) particles originating from rice husk or layered double hydroxide modified silica particles (FeAl-LDH@SiO2) as reinforcement. All the composites consisted of one layer of the impregnated fabric where the silica particles concentrations were 0.5 wt% and 1.0 wt% regarding PVB. The impact properties of the composite samples were analyzed by the controlled energy puncture impact tester. The structures of the composite samples were determined by the attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) and field emission scanning electron microscopy (FE-SEM). The results showed that the Kolon/PVB/1 wt% FeAl-LDH@SiO2 sample yielded the maximum impact force.

AB  - Rice husk was used to produce silica particles, which were then used to reinforce the polymer matrix. The synthesized SiO2 particles were characterized using X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. In a PMMA matrix, prepared SiO2 particles in amounts of 1, 3, and 5 wt.% were used as reinforcing agents. The goal of this research was to see if SiO2 particles had any effect on the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope (FE-SEM). Vickers microindentation hardness and impact testing were used to determine the mechanical properties of the obtained composites. The indentation creep’s behavior of a polymethylmetacrylate (PMMA) composite material with varying amounts of nanoparticles (SiO2) was investigated and analyzed.

AB  - Silica particles were produced form rice husk and used as reinforcement in the polymer matrix. The obtained silica particles' surfaces were modified with layered double hydroxides, which enabled better reinforcement in the PMMA matrix. Coprecipitation was used to synthetize Fe Al layered double hydroxides (LDH) with a Fe:Al cation content of 3:1 and an FeAl-LDH: silica ratio of 1:1. X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy with EDS were used to characterize the synthesized particles. The prepared particle amounts in the PMMA matrix were 1, 3, and 5 wt. %. The purpose of this study was to see if the obtained SiO2 particles, as well as their modification with FeAl-LDH, had any effect on the mechanical properties of polymer composite materials. The mechanical characterization of obtained composites was done using Vickers microindentation tests and impact testing. The Vickers micro-hardness test showed that the addition of reinforcement increases the hardness of the composite. When compared to the matrix, the toughness of the composite material with a higher content of particles (5 wt. %) in the energy absorbed in this impact test was three times higher.

AB  - An overview of advanced composite materials based on thermoplastic polymers for use in dentistry as basic materials for dentures and other industrial applications has been made. These advanced composite materials are reinforced using various oxide fillers. Alumina based particles were prepared from aluminium chloride hydroxide as starting material by sol-gel technique. One series of particles was doped with ferrous oxide. Both series of particles were calcinated at three different temperatures: 700 °C, 800 °C and 900 °C. It was investigated whether and how the calcination temperature of particles affects the microhardness and mechanical properties of composites. Another type of filler used were silica particles obtained from rice husk, as well as silica particles to which, double hydroxide particles were deposited as surface modifiers. The prepared particles were used in amounts of 1, 3 and 5 wt. % as reinforcing agents. Characterization of the synthesized particles was performed by X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. The development and synthesis of two acrylate matrices are presented. One of the matrices used is polymethylmethacrylate (PMMA) which has been thermally polymerized and used for denture materials. The mechanical properties of PMMA composites, such as hardness, impact resistance, tensile test and toughness of the material, were investigated. Photopolymerizable acrylates such as Bis-GMA (bisphenol A glycidyl methacrylate)/TEGDMA (triethylene glycol dimethacrylate) were used for the second type of matrix. This matrix was used to test the adhesion between a composite film with given particles as reinforcements on a metal surface. Three different methods were used to test adhesion: determination of film hardness and quantitative assessment of bond strength according to Chen Gao model; wetting angle between composite and substrate determination; and cavitation testing. The mechanical properties of composite materials are improved by increasing the reinforcement content. It is proved that the adhesion is improved with addition of the fillers.

AB  - Adsorption of anthraquinone dye Acid Blue 111 by alumina-iron oxide doped particles prepared by sol-gel method from aqueous solutions was studied. The adsorbent morphology was revealed by FESEM and the crystallographic phase is analyzed by the XRD technique. The effect of adsorbate and adsorbent concentrations, pH value, type of adsorbent and thermodynamic parameters on dye removal by adsorption was studied. The change of dye concentration during the adsorbtion was followed using the UV-Visible spectrophotometer. The change of the adsorbent surface before and after dye removal was observed using the Fourier Transformation-infrared spectroscopy (FT-IR). The adsorption kinetics is in accordance with the pseudo-second-order kinetics model. The Langmuir and Freundlich adsorption isotherm models were used to describe the adsorption process. The thermodynamic study of dye adsorption proves the process is spontaneous with exothermic nature. © 2021 Authors. Published by association for ETRAN Society.

AB  - Morphology and development of surface damage of alumina-based materials, resulting from cavitation erosion is studied in this paper. Two series of samples were prepared: samples without fibers and those with the addition of 2 wt % of ceramic fibers. The form of surface damage is considered to be the information carrier for the analysis of the resistance of materials to cavitation and the quality of this information is determined. The surface of the samples was monitored in defined time intervals in order to prepare the digitized image suitable for further analysis using image analysis software. The principal component analysis was applied to examine the appearance of certain morphological characteristics depending on the behavior of the material during cavitation erosion. It was concluded that the addition of ceramic fibers gained in importance after a long time of cavitation erosion, while during a starting period of time the difference in the morphology of the damage is not very observable. © 2021 Elsevier B.V.

AB  - As a renewable resource, starch is considered to be fully biodegradable and nonpolluting to the environment but the hygroscopicity of starch is the main disadvantage for wider applicability in the production of a polymer-based material. Hydrophobically modified starch prepared using natural-based plasticizers/modifiers in a first step ([-]-diisopropyl D-tartrate [DiPT], ricinoleic acid [RA] and epoxidized soybean oil [ESO]), and maleated polypropylene (MAPP) in a second step contributed to better compatibility, and thus reinforcing of composites. Tailored processing conditions, structural/morphological properties, hydrophobicity, and water-resistance of the modified starch were established. In addition, the Charpy impact and tensile strength of composites, based on poly(ethylene-co-acrylic acid) (EAA) and modified starches, were determined. Increased tensile strength and Young modulus of the composite using starch-modified with DiPT-MAPP, that is, 3 and 83%, respectively, indicated the possible applicability of obtained materials.

AB  - The goal of this study was to investigate the effect of the structure of Mn-Al layered double hydroxide (LDH) on the adhesion behavior of composite adhesives on two Al alloys (L3005 and L8079). The composite adhesives were made out of the UV-curing Bisphenol A glycidylmethacrylate/triethylene glycol dimethacrylate (BT) as polymer matrix and the addition of 1, 3, and 5 wt. % of Mn-Al LDH as adhesion enhancers. Adhesion was evaluated by using the micro Vickers hardness testing procedure. The wetting angle of composite adhesives to the Al substrates was measured and compared to the adhesion parameter b obtained from the microhardness tests. The highest increase in adhesion was observed for BT with 5 wt. % of Mn-Al LDH on L3005 substrate, which was more than 15 times higher than the adhesion for the neat BT. The morphological segregation of composite adhesives after the contact with Al substrates was examined by optical microscopy and a higher compatibility of Mn-Al LDH particles with L3005 substrate was found. The methods used for the adhesion properties assessment suggested that the Mn-Al LDH was the best adhesion enhancer of the BT matrix for L3005 substrate containing a higher content of Mn and surface hydroxyl groups.

AB  - Silica particles were obtained from rice husk to which layered double hydroxide particles were deposited (weight ratio 1 : 1). Fe2+-Al3+ layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios Fe : Al of 3 : 1 in the presence of SiO2 particles from the rice husk. Characterization of the synthesized FeAl-LDH@SiO2 particles was performed by X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. Prepared FeAl-LDH@SiO2 particles were used as reinforcing agents in 1, 3 and 5 wt% quantity in poly (methyl) methacrylate matrix. The aim of this study was to examine whether FeAl-LDH@SiO2 particles affect the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope. Microindentation, tensile and impact testing determined the mechanical properties of the obtained composites.

Fe2+-Al3+ layered double hydroxides (FeAl-LDH) were synthesized by co-precipitation with ratios Fe : Al of 3 : 1 in the presence of SiO2 particles from the rice husk. Characterization of the synthesized FeAl-LDH@SiO2 particles was performed by X-ray diffraction, Fourier transforms infrared spectroscopy (FTIR) and scanning electron microscopy with EDS. Prepared FeAl-LDH@SiO2 particles were used as reinforcing agents in 1, 3 and 5 wt% quantity in poly (methyl) methacrylate matrix. The aim of this study was to examine whether FeAl-LDH@SiO2 particles affect the mechanical properties of polymer composite materials. The morphology of the composites was examined using a field emission scanning electron microscope. Microindentation, tensile and impact testing determined the mechanical properties of the obtained composites.",

AB  - Cavitation erosion of hybrid acrylate composite films with polyhedraloligosilsesquioxanes (POSS) was investigated in this study. The hybrid films aremade with 1, 3 and 5 wt% of POSS reagents containing: (a) hydroxyl (POSS-M),(b) both hydroxyl and allyl (POSS-M-A) and (c) methacryloyl groups (POSS-MCl).Addition of 5 wt% POSS-M-A caused the highest microhardness increase for49.8%, in comparison to the pure matrix material. Cavitation resistance of hybridfilms, estimated as the time-dependent mass loss, was improved by POSS addition.POSS-M-A addition (5 wt%) contributed to 94% lower mass loss comparingto pure Bis-GMA/TEGDMA film. Scanning electron (SEM) and atomic forcemicroscopy (AFM) showed the lowest surface roughness obtained for compositewith POSS-M-A. The improved hardness and wear resistance of the compositefilms indicated that POSS-M-A filler enhanced interfacial adhesion and reinforcingof the Bis-GMA/TEGDMA matrix.

AB  - The objective of this study was to investigate the influence of polyhedral oligomeric silsesquioxane (POSS) structure on the adhesion behaviour of composite films onto a metallic surface. The composite films consisted of UV cured bisphenol A glycidylmethacrylate/triethylene glycol dimethacrylate (Bis-GMA/TEGDMA) as matrix and reactive POSS structures as adhesion enhancers. Composites were made with 1, 3 and 5 wt % of POSS. Adhesion was evaluated using the micro Vickers hardness testing method. The contact angle of composite films to a brass substrate was measured and compared to the adhesion parameter obtained from microhardness measurements. Optical microscopy indicated morphological segregation in the hybrid films suggesting the compatibility extent between the matrix and each particle. The shape and size of the indent were analyzed and correlated with adhesion quality. The methods used for the estimation of adhesion strength and quality clearly indicated that the highest adhesion enhancement of the Bis-GMA/TEGDMA matrix was POSS reagent containing both polar (hydroxyl) and nonpolar (unsaturated aliphatic - allyl) side groups. © 2020 Elsevier Ltd

AB  - Thermal properties of acrylate-based composite combined with alumina-based particles were investigated. The composites were made of poly (methyl methacrylate) (PMMA) modified with dimethyl itaconate (DMI) as a matrix. Neat alumina particles (Al2O3) and alumina doped with iron oxide (Al2O3-Fe) modified with 3-aminopropyl-trimethoxylane (AM) and flax oil fatty acid methyl esters (biodiesel - BD) were used as reinforcement. Thermal conductivity measurements showed that composite with alumina particles with the highest alpha phase content had the highest thermal conductivity values. Mechanical properties (tensile strength, modulus of elasticity and elongation at break) were improved by the addition of modified alumina particles to PMMA/DMI matrix. The thermal properties are the most improved for composite with 3 wt.% Al2O3-Fe-AM particles that had the lowest temperature in a crack zone was noticed (10.28 %) compared to PMMA added due to the better stiffness and highest thermal conductivity.

AB  - Aluminum oxide (Al2O3) is a ceramic material that has exceptional mechanical, physical and chemical properties. Due to its extraordinary chemical properties, aluminum oxide is used in composites as reinforcement and as material in high temperature applications. In composite materials of particular interest are different structures of aluminum oxide, which can be obtained by thermal treatment. The aim of this article was to make a composite material with a matrix made from PMMA itaconate copolymer and to examine the thermal properties, depending on the addition of various fillers with surface modification. Modulus of elasticity and the strengths of PMMA are in decrease by adding the itaconate to the matrix. Aluminum oxide based particles were used as reinforcement with a modified organosilane-3-aminopropyl-trimethoxylane (AM) surface and in the second stage with fatty acid fatty acid methyl esters (biodiesel-BD). Surface modification particles establish a better bond with the polymer matrix through covalent and hydrogen bonds and dipol-dipole interactions. Efficient dispersion of particles in the matrix also improves the transmission of the load through the matrix, which is followed by a thermionic camera. Thermograms during tensile test indicate differences in temperatures occurring in the fracture zone of composite materials. The temperature in the fracture zone is closely related to the efficiency of the load transfer and the temperature conductivity of the material itself. The mechanical properties of the material are improved by adding inorganic particles based on the activated surface of aluminum oxide, thereby creating a new composite material with improved mechanical and thermal properties.

Efficient dispersion of particles in the matrix also improves the transmission of the load through the matrix, which is followed by a thermionic camera. Thermograms during tensile test indicate differences in temperatures occurring in the fracture zone of composite materials. The temperature in the fracture zone is closely related to the efficiency of the load transfer and the temperature conductivity of the material itself. The mechanical properties of the material are improved by adding inorganic particles based on the activated surface of aluminum oxide, thereby creating a new composite material with improved mechanical and thermal properties.",

AB  - This study presents preparation and characterization of ethyl cellulose based nanocomposites. Successful use of simple solvent casting technique provided nanocomposites with high loads of barium ferrite magnetic nanopowder in the polymer matrix, promising significant improvement of mechanical properties. Investigation of morphology revealed formation of agglomerates that are still on nanoscopic level. Nanocomposite thin films with a higher content of the magnetic powder showed substantial enhancement of break strength, elongation and microhardness compared to the pure ethyl cellulose, which was the primary aim of this research.
