AB  - This paper outlines a novel simple protocol for tuning the structure and properties of jute using sodium periodate (NaIO4) oxidation and coating with alginate. When compared to the raw jute, fabrics oxidized with a 0.2 or 0.4 % NaIO4 solution for 30–120 min exhibited an increased aldehyde group content (0.185 vs. 0.239–0.398 mmol/g), a significantly increased negative zeta potential (from − 8.57 down to − 20.12 mV), a slight disruption of fiber crystallinity, 15.1–37.5 % and 27.9–49.8 % lower fabric maximum force and stiffness, respectively. Owing to the removal of hydrophobic surface barrier, decreased crystallinity index and the presence of micropores on thefabrics' surfaces, oxidized fabrics have a 22.3–29.6 % improved ability for moisture sorption compared to raw fabric. Oxidized fabrics characterized by very long wetting times and excellent antioxidant activities (> 98 %), can find applications as hydrophobic packaging materials. To further extend the utilization of jute in biocarpet engineering such as water-binding geo-prebiotic supports, oxidized fabrics were coated with alginate resulting in 7.9–24.9 % higher moisture sorption and 352–660 times lower wetting times than their oxidized counterparts. This modification protocol has never been applied to lignocellulosic fibers and sheds new light on obtaining jute fabrics with tuned structure and properties intended for various applications.

AB  - Kaolinite/illite (KUb) and sepiolite (SEP) clays were used to study Cr(III) adsorption removal from aqueous solutions so that they could be utilized after saturation for ceramic manufacturing. SEP had a larger specific surface area and a higher PZC than KUb. The removal of Cr(III) was evaluated using a batch equilibration procedure at pHi = 4 and pHi = 6. Fast removal kinetics were observed for both clays. Maximum removal capacity was determined by changing the concentration of Cr(III) while keeping the concentration of clay constant and by altering the amount of clay while keeping the concentration of Cr(III) constant. In all situations, SEP had greater capacity than KUb, and capacity was greater for both clays at higher pHi. Not only did the pHi impact the removal capacity and efficiency, but so did the pH during adsorption and the initial concentration of Cr(III). Because of the higher PZC, the pHf for SEP was higher for the same pHi. The higher the pH and Cr(III) concentration, the higher the probability of Cr(OH)3 precipitation and the higher the removal capacity. Dried saturated clays were uniaxially pressed and sintered at 1000 °C for 2 h. The densities of the sintered materials were nearly identical to those of pure clay-based materials, but the compressive strengths were higher, which is significant for the use of saturated clays as raw materials in ceramic manufacturing. Leaching of Cr from SEP-based material was significantly higher than from KUb-based material probably due to the presence of CaCO3 in the SEP.

AB  - The main drawback of resin-based composites (RBCs) widely used in restorative dentistry presents their volumetric shrinkage during the polymerization that can lead to clinical failures of restorations such asmarginal gap formation, bacterial microleakage, fractures, and postoperative sensitivity. To address this problem, sintered hydroxyapatite based dental inserts were introduced in the central part of molar teethrestoration, due to chemical and structural similarities with inorganic part of teeth.
The fabrication of bioceramic dental inserts based on HAP doped with Sr and/or Mg ions presents a way to obtain a dentin substitute that has even greater resemblance to the biological apatite in dentin. However, ion-substitutions arise lattice strain that can have a signifi cant impact on phase composition and properties of apatite materials, especially upon thermal treatment, which could be determining for their further application.
The aims of this study were to comparatively analyze physico-chemical and mechanical properties of the Sr- or Mg-, and Sr+Mg substituted HAP based dental inserts; and evaluate their possible application as dentinsubstitutes. Mono (5 mol. % Sr or Mg ions) and binary- (3 mol.% Sr and 3 mol.% Mg ions) doped HAP nanoparticles were hydrothermally obtained, isostatically pressed into compacts and eventually sintered at 1200°C to obtain dental inserts. The inserts are meant to be adhered to the cavity walls as well as topped with resin composite for sealing and esthetic purposes. Bonding ability of obtained inserts with different commercialrestorative materials, as well as fracture resistance of human molars restored with doped HAP inserts was investigated.
Ion doping was found to infl uence phase compositions of sintered inserts, leading to different mechanical properties and etching behavior of inserts. All inserts showed fracture toughness and bonding ability torestorative materials similar to dentin, while the highest bond strength was obtained for HAP insert doped with 5 mol% Mg (Mg-HAP) bonded to. Fracture resistance of human molars restored with Mg-HAP wasshown to be similar to the fracture resistance of the conventionally restored molars.

abstract = "The main drawback of resin-based composites (RBCs) widely used in restorative dentistry presents their volumetric shrinkage during the polymerization that can lead to clinical failures of restorations such asmarginal gap formation, bacterial microleakage, fractures, and postoperative sensitivity. To address this problem, sintered hydroxyapatite based dental inserts were introduced in the central part of molar teethrestoration, due to chemical and structural similarities with inorganic part of teeth.
The fabrication of bioceramic dental inserts based on HAP doped with Sr and/or Mg ions presents a way to obtain a dentin substitute that has even greater resemblance to the biological apatite in dentin. However, ion-substitutions arise lattice strain that can have a signifi cant impact on phase composition and properties of apatite materials, especially upon thermal treatment, which could be determining for their further application.
The aims of this study were to comparatively analyze physico-chemical and mechanical properties of the Sr- or Mg-, and Sr+Mg substituted HAP based dental inserts; and evaluate their possible application as dentinsubstitutes. Mono (5 mol. % Sr or Mg ions) and binary- (3 mol.% Sr and 3 mol.% Mg ions) doped HAP nanoparticles were hydrothermally obtained, isostatically pressed into compacts and eventually sintered at 1200°C to obtain dental inserts. The inserts are meant to be adhered to the cavity walls as well as topped with resin composite for sealing and esthetic purposes. Bonding ability of obtained inserts with different commercialrestorative materials, as well as fracture resistance of human molars restored with doped HAP inserts was investigated.
Ion doping was found to infl uence phase compositions of sintered inserts, leading to different mechanical properties and etching behavior of inserts. All inserts showed fracture toughness and bonding ability torestorative materials similar to dentin, while the highest bond strength was obtained for HAP insert doped with 5 mol% Mg (Mg-HAP) bonded to. Fracture resistance of human molars restored with Mg-HAP wasshown to be similar to the fracture resistance of the conventionally restored molars. In conclusion the obtained hydroxyapatite based dental inserts present promising materials for application as dentin substitutes inrestorative dentistry, which have the potential to extend the durability of the restoration.",

AB  - Limited bone bank capacity and risk of infection are some of the main drawbacks of autologous and allogenic grafts, giving rise to synthetic materials for bone tissue implants. The aim of this study was to process and evaluate the mechanical properties and bioactivity of magnesium and strontium doped hydroxyapatite (HAp) scaffolds and investigate the effect of adding zirconium oxide and gelatine coating the scaffolds. Doped nanosized hydroxyapatite powder was synthesized by the hydrothermal method and the scaffolds were made by the foam replica technique and sintered at different temperatures. Yttria-stabilized zirconium oxide (YSZ), synthesized by plasma technology, was used as reinforcement of calcium phosphate scaffolds. Element analysis, phase composition, morphology of the powders and microstructure of the scaffolds were investigated, as well as the compressive strength of the coated and uncoated scaffolds and bioactivity in simulated body fluid (SBF). A microporous structure was achieved with interconnected pores and bioactivity in SBF was confirmed in all cases. The best mechanical properties were given by the coated composite HAp/YSZ scaffolds, withstanding average stresses of over 1019 kPa. These results encourage the idea of use of these scaffolds in bone regenerative therapy and bone tissue engineering.

AB  - This study aimed to (1) comparatively analyze properties of Sr- and Mg-substituted
hydroxyapatite (HAP)-based dental inserts; (2) evaluate insert bonding to restorative
materials, and (3) evaluate the effect of doped HAP inserts on fracture resistance
(FR) of human molars with large occlusal restorations. By ion-doping with Sr or Mg,
3 insert types were obtained and characterized using XRD, SEM, Vickers hardness and
fracture toughness. Shear bond strength (SBS) was determined between acid etched or
unetched inserts and following materials: Maxcem cement (Kerr); Filtek Z250
(3M) bonded with Single Bond Universal (SBU; 3M) or Clearfil Universal (Cf; Kuraray).
Modified Class I cavities were prepared in 16 intact molars and restored using insert
+ composite or composite only (control) (n = 8/group). FR of restored molars was
determined by static load until fracture upon thermal cycling. Fracture toughness was
similar between Sr/Mg-doped inserts (0.94–1.04 MPam 1/2 p = .429). Mg-doped
inserts showed greater hardness (range 4.78–5.15 GPa) than Sr6 inserts (3.74
± 0.31 GPa; p < .05). SBS for SBU and Cf adhesives (range 7.19–15.93 MPa) was higher
than for Maxcem (range 3.07–5.95 MPa) (p < .05). There was no significant difference
in FR between molars restored with insert-containing and control restorations (3.00
± 0.30 kN and 3.22 ± 0.42 kN, respectively; p > .05). HAP-based inserts doped with
Mg/Sr had different composition and mechanical properties. Adhesive bonding to
inserts resulted in greater bond strength than cementation, which may be improved by
insert acid-etching. Ion-doped HAP inserts did not affect FR of restored molars. In conclusion,
HAP-based dental inserts may potentially replace dentin in large cavities, without
affecting fracture resistance of restored teeth.

AB  - This investigation represents a novel approach for tuning the jute structure and properties using sodium periodate (NaIO4) oxidation. The obtained results revealed that the jute fabrics exhibited an increase in the aldehyde group content (for up to 114.7%) with an increase in the NaIO4 concentration and/or oxidation duration. Due to the decline in the cellulose lateral order index (LOI) and fiber crystallinity index after oxidation, it can be concluded that jute crystalline areas are affected by sodium periodate oxidation. Both mentioned parameters are responsible for fabric mechanical properties, so, it was expected that by decreasing the LOI and jute fibers’ crystallinity, their maximum force and stiffness will decrease too. This behavior is also attributed to the fiber damage, which is the most pronounced for the fabric treated with 0.4% NaIO4 for 120 min. Besides slightly deteriorated mechanical properties, fabrics oxidized with 0.2% NaIO4 for 60 or 120 min and with 0.4% NaIO4 for 60 min showed lower mass loss (6.78-12.22%) after 750 abrasion cycles compared to the raw jute (18.94%). Furthermore, oxidation led to obtaining fabrics with enhanced moisture sorption and water retention power that are inversely proportional to the fiber crystallinity. Due to the opportunity for tuning fiber structure and properties oxidized fabrics can be considered for various applications such as geo-prebiotic supports for cyanobacteria growth in biocarpet engineering, i.e., to promote a sustainable relationship between the microbiota and abiotic constituents on the degraded land surface.

AB  - Recently, many studies have shown various beneficial effects of polyphenol resveratrol (Res) on human health. The most important of these effects include cardioprotective, neuroprotective, anti-cancer, anti-inflammatory, osteoinductive, and anti-microbial effects. Resveratrol has cis and trans isoforms, with the trans isoform being more stable and biologically active. Despite the results of in vitro experiments, resveratrol has limited potential for application in vivo due to its poor water solubility, sensitivity to oxygen, light, and heat, rapid metabolism, and therefore low bioavailability. The possible solution to overcome these limitations could be the synthesis of resveratrol in nanoparticle form. Accordingly, in this study, we have developed a simple, green solvent/non-solvent physicochemical method to synthesize stable, uniform, carrier-free resveratrol nanobelt-like particles (ResNPs) for applications in tissue engineering. UV–visible spectroscopy (UV-Vis) was used to identify the trans isoform of ResNPs which remained stable for at least 63 days. The additional qualitative analysis was performed by Fourier transform infrared spectroscopy (FTIR), while X-ray diffraction (XRD) determined the monoclinic structure of resveratrol with a significant difference in the intensity of diffraction peaks between commercial and nano-belt form. The morphology of ResNPs was evaluated by optical microscopy and field-emission scanning electron microscope (FE-SEM) that revealed a uniform nanobelt-like structure with an individual thickness of less than 1 μm. Bioactivity was confirmed using Artemia salina in vivo toxicity assay, while 2,2–diphenyl-1-picrylhydrazylhydrate (DPPH) reduction assay showed the good antioxidative potential of concentrations of 100 μg/ml and lower. Microdilution assay on several reference strains and clinical isolates showed promising antibacterial potential on Staphylococci, with minimal inhibitory concentration (MIC) being 800 μg/ml. Bioactive glass-based scaffolds were coated with ResNPs and characterized to confirm coating potential. All of the above make these particles a promising bioactive, easy-to-handle component in various biomaterial formulations.

AB  - The aim of this study was to investigate the influence of binary Sr, Mg ion-doping compared to the single-ion doping effects on the phase composition and morphology of hydrothermally obtained calcium hydroxyapatite (HAP) powders and on the phase composition, microstructure, and mechanical properties of the sintered materials. Additionally, the focus of this study was to investigate the possible utilization of the binary doped Sr,Mg-HAP compacts as dentin substitutes in restorative dentistry by evaluating their bonding ability with commercially available restorative materials using the shear bond strength test (SBS). The hydrothermally obtained mono-doped Mg5 and Sr5 showed the monophasic apatite structure, while in all co-doped samples β-TCP phase was formed, resulting in biphasic calcium phosphate (BCP) powders. It was confirmed that co-doping with Sr and Mg ions led to the thermal stabilization of the β-TCP phase by suppressing the phase transition into α-TCP when sintered at 1200 °C. Moreover, the co-presence of Mg ions significantly improved the hardness of Sr-doped HAP from 3.74 to 5.02 GPa. Sr,Mg-HAP dental inserts were found to achieve sufficient bonding (13.53 MPa) through the micromechanical interlocking with Z250 dental composite and Single Bond Universal dental adhesive applied with a total etch approach. The SBS values obtained for the SrMg-HAP insert were similar to the literature data on bonding ability with human dentin, indicating that binary doped Sr,Mg-HAP ceramics present a promising material for application in restorative dentistry as dentin substitutes.

AB  - Tooth caries presents one of the most common diseases worldwide, and its treatment involves
removal of the decayed tooth structure, and the cavity restoration using restorative dental materials. Resin based composites (RBCs) are the most commonly used restorative material in practice owing to their great aesthetic appearance allowing the clinicians to adapt the nuance of the restoration to the patient’s tooth color. However, the RBCs harden by the polymerization of monomers that leads to the polymerization shrinkage of the restoration, leaving the micro-gaps at the teeth-restorations interface which allows the secondary caries formation.

AB  - Biomaterials engineering is one of the strongest research areas at the Faculty of Technology and Metallurgy (FTM), University of Belgrade including development of novel biomaterials for orthopaedic and dental applications. Especially, synthesis and physico-chemical characterization methods are well established resulting in variety of novel inorganic, polymer and composite biomaterials produced in different forms with controlled compositions and structures. Still, expertise in further advancement of the research results towards utilization in medical devices is lacking. The ExcellMater Horizon 2020 project aims to further advance the scientific and technological capacity of the Faculty in this area by twinning the knowledge from the three European partners, internationally leading institutions, with recognized expertise in biological characterization methods, intellectual property protection and utilization, evaluation of health technologies and regulatory aspects of medical devices. The aim of the project is also to increase visibility of scientific research and enhance collaboration of engineers at FTM with life scientists, medical doctors and pharmacists as well as with industry. Here, we will present some of the novel bioceramic and composite biomaterials developed at FTM aimed for potential applications in orthopaedics, dentistry, bone tissue engineering, and cancer research.

AB  - Pyrolytic tire (PT) chars were first produced from waste car tires (WCT) through carbonization process at 800 degrees C, for different retention times. Then, best PT-char sample by its physicochemical properties (WCT 800(1 h)) was further tested for its ability to adsorb Rhodamine B (RhB) dye from aqueous solutions. Structural characterization of synthesized material showed existence of graphene-based material, with average pore diameter of 22.8 nm and specific surface area of 55.8 m2.g- 1. Obtained carbon material meets specifications of commercial carbon black (CB). The yield of 33.6% of CB recovered has been achieved. Under the optimal conditions, 99.57% of RhB was removed. Adsorption of RhB obeys pseudo second-order model and Langmuir isotherm model. DFT (the density functional theory) was revealed that effective bonding of RhB onto WCT 800 originates from pi-electron interactions with aromatic moieties and chemical (or at least the electrostatic) interactions, between positive nitrogen and electron-rich surface groups.

AB  - Decayed or damaged tooth structure is widely being repaired with the resin
based dental composites (RBCs) in the clinical practice. However, relatively high failure rate
and short lifespan are common in the case of the larger posterior teeth restorations,
caused by the polymerization shrinkage of RBCs. In order to reduce the polymerization
shrinkage inorganic dental inserts were introduced. The aim of this study was to fabricate
dental inserts based on hydroxyapatite doped with 5 mol. % of magnesium ions (MgHAP)
and determine their bonding ability with a restorative material widely used in the clinical
practice – Clearfil Universal adhesive. The MgHAP powder and insert were characterized
using energy dispersive X-ray (EDX) analysis, X-ray diffraction (XRD) analysis and scanning
electron microscopy (FE-SEM). Bonding ability of the inserts with restorative material was
measured by shear bond strength (SBS) test, and the type of fracture was determined by
the optical microscope. The obtained mean SBS value of the MgHAP inserts was 12.7 MPa,
with mostly cohesive type of the fracture present. These inserts present promising dentin
substitutes for application in the restorative dentistry.

AB  - The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to assist in the bone/tooth healing process, prevent post-implementation infections and provide satisfying values of hardness and fracture toughness for biomedical application. Ion doping was done during the hydrothermal synthesis of HAP powders, whereby the content of Mg ions in the starting solution was varied between 1-20 mol. % with regard to Ca ions, while the amount of Cu ions was kept constant at 0.4 mol. %. The green compacts were sintered for 2 h at temperatures ranging 750-1200 degrees C depending on the Mg content, chosen in agreement with dilatometry results. Presence of Mg ions was found to favour transition from HAP to beta-tricalcium phosphate phase (beta-TCP), which enabled formation of biphasic HAP/beta-TCP and pure beta-TCP phase at 160 degrees C during hydrothermal synthesis. In vitro investigation of antimicrobial activity against Escherichia coli, Staphylococcus aureus and Enterococcus faecalis showed satisfactory antimicrobial activity. MTT assay performed on MRC-5 and L929 cell lines showed excellent cytocompatibility and cell proliferation. Maximum hardness by Vickers and fracture toughness values, 4.96 GPa and 1.75 MPa m(1/2) respectively, were obtained upon addition of 5 mol. % Mg, as a consequence of the lowest grain size and porosity, as well as the highest densification rate. This is, to the best of our knowledge, the highest fracture toughness for HAP or beta-TCP ceramics reported thus far.

MTT assay performed on MRC-5 and L929 cell lines showed excellent cytocompatibility and cell proliferation. Maximum hardness by Vickers and fracture toughness values, 4.96 GPa and 1.75 MPa m1/2 respectively, were obtained upon addition of 5 mol. % Mg, as a consequence of the lowest grain size and porosity, as well as the highest densification rate. This is, to the best of our knowledge, the highest fracture toughness for HAP or β-TCP ceramics reported thus far.",
