AB  - Cholesterol as very important biomolecule is the precursor of many biologically significant compounds which give strength and flexibility to the biological membranes. It is also a crucial component in lipoproteins, and has an important role to transport hydrophobic molecules in hydrophilic media such as blood [1, 2]. The analytical performance of carbon paste electrodes (CPE) bulk modified with ionic liquid 1-allyl-3-methylimidazolium dicyanamide ([AMIM][DCA]), and surface modified with platinum on graphitized carbon (Pt-C) or platinum-ruthenium alloy on graphitized carbon (Pt,Ru-C) for analysis of hydrogen peroxide (H 2O2) were compared. The prepared working electrodes were characterized using scanning electron microscopy–energydispersive X-ray spectrometry, together with electrochemical impedance spectroscopic, cyclic voltammetric, and amperometric techniques. After method optimization, an enzyme cholesterol oxidase (ChOx) was immobilized on the surface of Pt,Ru-C/IL-CPE by Nafion®. The improved cholesterol amperometric determination was achieved in phosphate buffer solution pH 7.50 at a working potential of 0.60 V. Under the optimized experimental conditions, a linear relationship between oxidation current and cholesterol concentration was in the concentration range from 0.31 to 2.46 µM, with an estimated detection limit of 0.13 µM and relative standard deviation (RSD) below 4.2%. The optimized amperometric method in combination with the developed ChOx/Pt,Ru-C/IL-CPE biosensor showed good repeatability and high selectivity towards cholesterol biosensing despite the presence of possible interferences. The ChOx/Pt,Ru-C/IL-CPE was tested for the determination of the free cholesterol, by its enzymatic reaction product H 2O2, in a human blood serum sample. The percentage recovery ranged from 99.08 to 102.81%, while RSD was below 2.0% for untreated, as well as for spiked human blood serum sample.

AB  - The aspect of the detection of hydrogen isotopes in nuclear materials was analyzed in this review. Particular attention was paid to the spectroscopic methods for the detection of hydrogen isotopes in fusion reactor materials since their presence can induce severe problems in terms of material degradation and shortening of its lifetime. The main focus is on laser-induced breakdown spectroscopy, an optical emission method that is efficient, reliable, and fast. Recent results obtained at the VINCA Institute will also be presented.

AB  - Carbon quantum dots (CQDs) are well known as a promising therapeutic agent due to their excellent pro-oxidant, antioxidant, antibacterial and anticancer properties under visible light irradiation. This material is easy to produce by several bottom-up or top-down methods. In this study, we used citric acid as starting precursor to synthesize aqueous carbon quantum dots dispersion by pyrolysis at 210 ◦C. Atomic force microscopy and XPS analyses revealed that CQDs synthesized are quasi-spherical with typical diameter of 9 nm and lots of C–O and C––O functional groups distributed over the basal plane and edges of the dots. Here, we investigated the antiviral properties of CQDs against cytomegalovirus (CMV). The pre-treatment with CQDs upregulates interferonstimulated genes (ISG), resulting in better virus control. Cellular defence against cytomegalovirus of CQDs pre-treated cells is increased in a dose-dependent manner. Our results reveal high biocompatibility and potent in vitro antiviral properties of CQDs.

AB  - The increasing popularity of luminescent nanothermometry in recent years can be attributed to its application potential in biomedicine. In response to this need, we describe a biocompatible bimodal luminescent thermometer that operates in ratiometric and luminescence lifetime modes based on particles of MgTiO3:Cr3+,Nd3+@SiO2. The introduction of Cr3+ and Nd3+ dopants enabled the luminescence of Ti3+ ions to be observed, and the difference in the thermal quenching rates of Cr3+ (4T2→4A2), Ti3+ (2T2→2E) and Nd3+ (4F3/2 → 4I11/2) ions enabled the ratiometric thermometers. The highest sensitivity reaching SR = 1.00%K−1 was obtained for MgTiO3:0.1 % Cr3+, 0.1 % Nd3+ at 203 K. The shortening of the lifetime of the 4T2 level of Cr3+ ions associated with its thermal depopulation allows to develop a lifetime-based thermometer with a relative sensitivity reaching 0.85–1.18%K−1 in the physiological temperature range. The deposition of a SiO2 shell on a MgTiO3:Cr3+,Nd3+ did not introduce significant changes in the shape of the emission spectrum and slightly elongates the lifetime by reducing the probability of surface-related nonradiative processes. More importantly, the thermometric performance of this luminescence thermometer was preserved. The low cytotoxicity of the obtained materials underlines their potential in bioapplications of the described luminescent thermometers.

AB  - Irradiated fig pomace pyrochar (IrrPyrFP) is noteworthy as a novel sterilized low-cost sorbent of BTEX, pesticides, and Pb2+ ions. It was produced by applying pyrolysis treatment followed by gamma irradiation modification in order to obtain a highly efficient and sterile sorbent. The characterization of fig pomace before and after pyrolysis, as well as before and after irradiation of the obtained pyrochar, was done using SEM, FTIR, and elemental analysis, while its sorption ability was tested through the removal of examined pollutants by batch sorption experiments. The obtained results suggest that IrrPyrFP could play a significant role in the control of environmental pollutants, as indicated by the maximum adsorption capacities: 42 mg g−1 for BTEX, 0.625 mg g−1 for malathion, 0.495 mg g−1 for chlorpyrifos and 255 mg g−1 for Pb2+. A kinetic study showed that the removal process by IrrPyrFP mainly follows pseudo 2nd kinetics order, while the sorption equilibriums were estimated using the Langmuir and Freundlich model. Overall, the findings of this work suggest that pyrolysis and activation by irradiation of waste biomass is a promising way to produce sterile efficient sorbents for waste-water treatment based on green chemistry. Additionally, the demonstrated application of fig pomace promotes the potential of using this biomass for continual and economical waste management in the rising fig industry.

AB  - Eu3+ doped Zirconia coatings were synthesized by the electrochemical plasma electrolytic oxidation method in only 8 min from the pure zirconium substrate. The phase constitution from pure monoclinic to pure tetragonal and exactly in between was achieved by using different concentrations of Na3PO4 and NaAlO2 electrolytes. The complex emission spectra composed of Eu2+, Eu3+, and ZrO2 defect emission greatly depend on the excitation wavelength and phase constitution. Eu3+ photoluminescence properties depend on the phase, which is reflected by the different Stark splitting and different intensities of transitions. Thus, both phase and photoluminescent properties of ZrO2 coatings are fine-tuneable. Judd-Ofelt analysis was performed from the emission and excitation spectra, showing that all 3 intensity parameters depend linearly on the phase constitution, being largest in the pure monoclinic phase. The mixed phase has Judd-Ofelt parameters between those in pure phases. Eu3+ has 2.45 times more preference to get incorporated into the tetragonal than in the monoclinic phase in the mixed phase samples. The general equation for Judd-Ofelt parameters in a compound with mixed constituents and probability of incorporation is introduced, allowing also for a prediction of the spectrum shape based on the Judd-Ofelt parameters of pure-phase compounds. Python software code for estimating the percent of incorporation by multiple linear regression model is also provided.

AB  - We report on the results of the first principles calculations based on density functional theory (DFT) of the electronic structure and mechanical properties of K2LiAlF6, both non-doped and doped with Cr3+ ions. The densities of states of K2LiAlF6 and the K2LiAlF6:Cr3+ phosphor as well as the crystal-field strength 10Dq, the Cr3+ 2E→4A2 emission energy, elastic constants, bulk and shear moduli, sound velocities and Debye temperature as functions of hydrostatic pressure ranging from 0 up to 40 GPa were calculated. The present DFT calculations indicate that, the band gap of non-doped K2LiAlF6 increases quadratically with increasing pressure. Further, the crystal field strength 10Dq and the 2E→4A2 emission energy, the Debye temperature, sound velocities and shear moduli of Cr-doped K2LiAlF6 increase with increasing pressure, while the 2E→4A2 emission energy becomes red-shifted, which indicates potential applicability of the studied system for pressure sensing. Such calculations for the title system were performed for the first time; the obtained results provide a firm basis for a deeper understanding of physical properties of both neat and doped functional materials.

AB  - Thirty-two glasses from four Byzantine fortifications located on the Danube in Serbia, dated to the sixth-century CE, are analysed by PIXE/PIGE, and their compositional types are determined. Most of the glasses belong to Late Antique type Foy 2.1 (22), the rest being Foy 3.2 (3), HIMTa (1), Levantine (2), plant-ash (3), and coloured black (1). The diversity of compositional types and provenances characterizing the same area during the third to fourth century, changed in the sixth century into uniformity of glass types and provenance: more than two-thirds of all glass types represent only one type (Foy 2.1), and at least 87% of all imports came from a single region, Egypt. Apart from two glasses reported herein, no Levantine glasses are reported from Serbia, and almost none from the inner Balkans, which is in contrast with the rest of the Mediterranean excluding Egypt. The reasons for this might be the economic aftermath of earlier Hunnic raids or possible centralization of raw glass imports during the Justinian rebuilding program. Two plant ash glasses of mixed composition, showing characteristics of Egyptian plant-ash flux and Mesopotamian sand, likely represent recycled glass originating from these two regions.

AB  - The creation of novel biocompatible Ti-based thin films with a Zr or Cu sub-layer modified by ultrafast laser processing is studied. To prepare bioactive surfaces, ultrafast laser processing is focused on the formation of laser-induced periodic surface structures (LIPSS) with the production of oxide phases at the surfaces. Two differently designed multilayer thin films Ti/Cu/Ti and Ti/Zr/Ti were deposited on the silicon using the ion sputtering method. The Ti thin film contains Cu or Zr sub-layer (thickness of 10 nm) at the 10 nm below the surface. The composition and surface morphology variations for these systems, deposited and laser-processed under the same experimental conditions, were caused only by different thermo-physical properties of the sub-layer (Cu or Zr). The surface morphology in the form of LIPSS, led to improved cell adhesion and stable cells/thin films interface compared to as-deposited samples. Field-emission scanning electron microscopy and MTT analysis revealed that laser processing of both systems increased cell adhesion, proliferation, and metabolical activity of L929 mouse fibroblast cells compared to non-modified flat surfaces. Overall, the biocompatibility of Zrcontaining thin films is better than Ti/Cu/Ti system. Further, laser processing and formation of LIPSS makes Ti/Zr/Ti thin films excellent candidate for biomedical

AB  - Increased fructose intake via industrial food is associated with metabolic syndrome(MetS). MetS is characterized by chronic low-intensity inflammation caused by oxidativestress and activation of the renin-angiotensin system (RAS). Walnuts are a rich source ofantioxidants and polyunsaturated n-3 fatty acids that exert anti-inflammatory/immunomodulatory effects on cardiometabolic health, which molecularbackground is underexplored.Walnut consumption (2.4 g/day, 6 weeks) reduced systolic blood pressure in ratsfed a fructose-rich diet (10% FRD, 15 weeks), showed a protective effect on theantioxidative axis SIRT1-FoxO3a-MnSOD/catalase and anti-inflammatory cardiac capacity(AA/EPA reduction) and promoted the anti-inflammatory profile of plasma fatty acids(AA/EPA and AA/DHA reduction), which were compromised by FRD. The role of theaxis negative regulators, Nox4 and ChREBP, should be further investigated in the heartbecause the Nox4 level was increased by both, FRD and walnut supplementation, whilethe ChREBP nuclear level was reduced in FRD as well as in control rats subjected towalnuts. FRD activated a signaling pathway that regulated inflammation by increasing thelevels of the transcription factor NF-κB and the key RAS enzyme, ACE, while walnutsupplementation in FRD rats increased ACE2 level, a cardioprotective component of theRAS. The protein/mRNA levels of the RAS receptors, AT1R and AT2R, were not affectedby either of the two nutritional factors.This study confirmed the beneficial effects of walnut consumption oncardiometabolic status and proposed the mechanisms underlying their anti-inflammatoryand antioxidative effects in the heart, indicating the possibility for development of novel,non-pharmacological approaches in cardiometabolic disease therapy.

AB  - Mine waters and tailings resulting from mining and mineral processing often have a harmful effect on the local environment. Copper has a strong biocidal activity that greatly affects ecosystems. Therefore, the removal of copper from wastewater is of great importance to the environment. Chitosan, a natural biopolymer, obtained from chitin, the most abundant natural fiber, often has better properties than much more expensive synthetic polymers. This paper investigates the application of chitosan-based sorbents for removing copper from aqueous solutions. A novel adsorbent, chitosan hydrogel beads (CHBs), was synthesized from chitosan flakes (medium molecular weight), via ionic/covalent cross-linking. Batch experiments were carried out to optimize the process conditions for efficient removal of Cu(II) and to determine the adsorption capacity of prepared CHBs. The results showed that the maximum Cu(II) adsorption capacity estimated with Langmuir isotherm modeling was 103.6 mg/g which was three times higher than chitosan flakes (33.7 mg/g).

The results showed that the maximum Cu(II) adsorption capacity estimated with Langmuir isotherm modeling was 103.6 mg/g which was three times higher than chitosan flakes (33.7 mg/g).",

AB  - The present study investigated potential application of biopolymer chitosan, in the form of gel beads, for the removal of Congo red (CR) dye from aqueous solution. Chitosan hydrogel beads (CHBs) were prepared by a coupled ionic and covalent co-cross-linking, employing citric acid (CA) and glutaraldehyde (Glu) as an ionic and a chemical crosslinker, respectively. Batch experiments were carried out to optimize the process conditions for efficient removal of CR dye and to determine the adsorption capacity of prepared CHBs. The results showed that the highest removal efficiency of CR was obtained in the pH range from 6 to 10, and that the equilibrium was attained after 180 min. The Langmuir isotherm model provided the best correlation for the adsorption of CR onto CA/Glu cocross-linked CHBs, with the maximum adsorption capacity (qm) of 544.2 mg g-1 .

AB  - In our previous publication [1] we studied the wake potential induced by an external charged particle that moves parallel to various sy1 -Al2O3-sy2 composites, where syi (with i=1,2) may be vacuum, pristine (undoped) graphene, or doped graphene. Several important parameters were fixed at their respective typical values: the distance of the charged particle from the closest surface, the thickness of the Al2O3 layer, and the doping density of graphene. In our recent publication [2] we presented a detailed study of the effects due to variations of all those parameters in the case of the wake potential produced by the charged particle moving parallel to the graphene-Al2O3-graphene composite system. In both mentioned publications we assumed a zero gap between graphene and insulator to simplify calculations. In this work we assign for the first time a finite gap size between graphene and insulator, and vary the speed of the projectile moving parallel to the structure and the particle distance. Using the Dyson-Schwinger equation [3] we recalculate the wake potential in the graphene-insulator-graphene heterostructure and study the effects of the graphene-insulator distance. The polarization functions of graphene sheets are obtained using two approaches within the random phase approximation [3]: an ab initio method and a method based on the massless Dirac fermion approximation. The dynamic response of the insulator layer is described by a dielectric function consisting of several Lorentzian terms.

AB  - Rapid growth of human population has led to increased water demand by various industries and production of large amount of wastewater. Textile, leather, paper, and plastics industries wastewater, which contains organic pollutants such as dyes, needs a proper treatment in order to be safely discharged into the environment, therefore, new methods are being developed. This research is based on investigation of photocatalytic degradation of an azo-type dye Congo Red (CR) by using powdered UiO-66 type MOF (Metal Organic Framework), activated carbon (AC) and their composite powder mixtures made with different MOF/AC ratios. Additionally, this research includes investigation of renewability of these materials in several experimental cycles. Experiments were performed in batch conditions, samples were exposed to solar light irradiation, then centrifuged to remove solid particles and in order to determine the concentration of the remaining dye, solutions were analyzed by UV-ViS spectrophotometer. Renewability of the photocatalysts used in experiments was investigated by repeating this process three times, with catalysts dried at 50 °C between cycles. Results have shown that pure MOF has excellent and almost identical photocatalytical efficiency in every cycle, compared to all MOF/AC composites and pure AC, probably due to the saturation of available adsorption sites in AC. CR removal efficiency and renewability of various composites depends on MOF/AC ratio, therefore, the most efficient composites are the ones where MOF content varies from 25 wt. % up to 100 wt. %. Samples with MOF content 50 - 100 wt. % have shown excellent renewability, while composites where AC is more dominant (95 - 100 wt. %) have shown almost none. Among the composites examined in this paper, the one with MOF/AC ratio of 50/50 has shown the best cost/performance ratio in removal of Congo red dye from aqueous solution.

AB  - Technetium-99 (99Tc), as one of the important high-yield fission products, is a significant threat to the environment and human health. It is produced in large amounts by nuclear fission of 235U or 239Pu in nuclear reactions, though the quantity of Tc produced by the spontaneous fission of 238U or by decay of 99Mo in the nature which is very small. 99Tc in the environment originates from nuclear weapons tests, discharges from nuclear power plants, nuclear medicine and radiobiology. These activities generate large volumes of low and intermediate radioactive waste which can cause a significant impact on the environment if disposed without suitable treatment. Immobilization of 99Tc into a relatively small volume waste is vital for long term permanent disposal. High mobility and long half-life of 99Tc considered to be one of the most important radionuclides in safety assessment of environmental radioactivity as well as nuclear waste management. Effective removal of radioactive technetium (99Tc) from contaminated water is of enormous importance from an environmental and public health perspective, yet many current methodologies are highly ineffective. This paper summarizes physico-chemical separation procedures emphasizing those that are the most used in practice. Classic sorbents such as activated carbons, ion exchange resins as well, as new materials, such as metal−organic frameworks and graphene based membranes are described in the paper.

AB  - In this work, the coefficient of fluid-wall mass transfer in an inverse fluidized bed was determined using the adsorption method. The experiments were carried out in a column with a diameter of 45 mm with spherical and non-spherical particles of polypropylene and polyethylene with a diameter of 3.3-4.9 mm and a density of about 930 kg m-3. A diluted solution of methylene blue was used as a fluidization medium, which was adsorbed on part of the surface of the column on silica gel. The obtained results showed that the presence of particles during inverse fluidization does not contribute significantly to mass transfer compared to the influence of particles on transfer in conventional fluidized beds. Therefore, the pseudofluid concept was introduced into the analysis and an empirical correlation was performed to determine the mass transfer coefficient. The obtained results were compared with literature correlations for inverse and conventional fluidized beds.

AB  - We studied the influence of Ag doping on the crystal structure and magnetic properties of CuO nanopowders. For the synthesis of nanoparticles of copper-silver oxides solid solutions with the composition Cu1-xAgxO (x=0.01–0.05), a self- propagating synthesis was applied at room temperature, during which a successful reaction between metal nitrate and sodium hydroxide occurred. Prepared powders were calcinated at 700 °C for 2 h. The diffraction pattern was recorded at room temperature and atmospheric pressure without of any re-heating of the sample. The Rietveld method for fitting refinement procedure was performed which showed the incorporation of Ag3+ ions in the CuO crystal lattice, where they substitute Cu2+ ions. SQUID magnetometer was used for investigation of magnetic behavior of synthesized materials in temperature interval 2–400 K. It is known that copper(II) oxide exhibits ferroelectricity driven by magnetic order at temperature as high as 230 K [1]. Multiferroic phase is present above the first order phase transition at TN1 = 213 K and exists up to the subsequent first order phase transition TN2 = 230 K [1,2]. It was shown that disorder in the form of impurities can stabilize the ferroelectric phase [2] this was our motivation to dope CuO with Ag in order to improve further its multiferroic properties. Compared with CuO, we observed small changes in magnetic properties in Cu1-xAgxO. The size and morphology of the particles were successfully determined by transmission electron microscopy (TEM) and scanning electron microscopy (SEM).

AB  - The main aim of this research is to show influence of different hydroxides, applied in carbon materials activation process on the electrochemical properties of activated carbon samples. The carbon material samples were prepared by hydrothermal treatment of sucrose and thermally activated using KOH, NaOH and LiOH by chemical activation method. The electrochemical properties of the obtained carbon material samples were examined by cyclic voltammetry and electrochemical impedance spectroscopy and correlated to their physicochemical properties. Investigated samples showed characteristic capacitor-like behavior. The best result of specific capacitance was obtained for the sample synthesized treated by KOH, while the increase in capacitance follows the arrangement of the growth of ionic radius of a metal from an alkali which is used for activation. Dependence on the type of hydroxide is due to differences in the radii of a metal. The alkalis with larger radii of metal produce wider pores and consequently the structure of a porous layer become more accessible and available to the charge transfer of capacitive response.

AB  - The examination of different raw materials as precursors for obtaining carbon materials is an important area of research due to the wide range of applications for carbon materials in various fields, including energy storage, catalysis, and electronic devices. Some of the commonly studied precursors for carbon materials include biomass, petroleum-based precursors, waste materials, natural materials. The selection of a precursor material depends on various factors, such as the intended application of the carbon material, the availability and cost of the precursor, and the properties of the resulting carbon material. Different precursors can result in carbon materials with varying structures, porosities, and surface chemistries, which can affect their properties and performance in different applications. In our work, we used cherry pits, sour cherry, vineyard peach pits, bean and pea husks. The properties of the initial precursors were tested and then they were treated physically and chemically at different temperatures and times. Correlation of the properties between the initial and final samples was made, as well as their potential application in relation to the obtained properties.

AB  - Brassinosteroids (BRs) are a class of plant hormones that play important roles in regulating various physiological and developmental processes in plants. One of the most effective BRs involved in modulating crop growth is 24-epibrassinolide (24-EBL). The effects of different concentrations of 24-EBL on various biochemical and biophysical parameters critical to early growth stages and seedling development were investigated using two maize hybrids, ‘ZP 434’ (a new-generation hybrid) and ‘ZP 704’ (an older-generation hybrid). The evaluation of results is based on measurements of germination percentage, morphometric parameters, redox status, comparative analysis of thermodynamic parameters (such as Gibbs free energy, enthalpy, entropy), and the concentration of specific sugars in different parts of maize seedlings. The results indicate that the germination and initial growth of maize seedlings are influenced by the flow of crucial sugars from the remaining seed (as a source of nutrients) towards the plumule and radicle (as sink organs). Furthermore, alterations in Gibbs free energy play a significant role in these sugar transfers within the maize seedlings. The seed germination was most affected by the highest concentrations of 24-EBL, showing inhibitory effects, whereas lower and moderate concentrations of exogenously added 24-EBL exhibited a beneficial influence on the initial phases of seedling growth. The mentioned approach gives new insights into source–sink relationships and can be used as a quantitative measure of the germination energy, which until now has been a qualitative criterion in seed science.

AB  - The influence of unconventional alkaline additives (ground seashells and bauxite residue) on the copper (Cu) sorption and retention capacity of acidic soil was investigated. The soil collected near the mining and metallurgical complex in Bor (Serbia) was treated with different doses of additives, and the Cu sorption and desorption were assessed in batch conditions. The waste-derived materials proved to be efficient and sustainable alternatives to conventional alkalizers, increasing the maximum sorption capacity for Cu in correspondence with the soil pH increase. Nevertheless, added Cu was largely mobilized by weak acid extraction, demonstrating the importance of maintaining optimal soil pH for Cu leaching prevention.

AB  - There is a global tendency to reduce the consumption of energy required for heating as well
as cooling buildings. Therefore, thermal insulation technology becoming important in
preventing both, the gain and loss of heat through the building envelope. This work aims to
evaluate the feasibility of using inexpensive raw materials such as kaolin and waste material
such as seashells and banana peel for fabrication of the sustainable anorthite-based porous
ceramics for thermal insulation. Kaolin was used as a source of Al2O3 and SiO2, seashells as a
source of CaO whereas banana peel was used as a pore former. The phase composition, bulk
density, open porosity, compressive strength, microstructure, and thermal conductivity of the
ceramic samples, were analyzed. The obtained results showed that the variation of pore former (banana peel) content and sintering temperature was an effective way to control the
thermo-mechanical properties of the obtained anorthite ceramics. Samples with open porosity
(1.4 – 45%), compressive strength (>15 MPa), bulk density (1.87-2.62 g/cm3
), and thermal
conductivity (0.097-3.67W/mK) were obtained after sintering of samples with different
percent of banana peel at 1100–1200 ◦C. It suggests that the obtained porous ceramics can be
used for cost-effective thermal insulation of buildings.

abstract = "There is a global tendency to reduce the consumption of energy required for heating as well
as cooling buildings. Therefore, thermal insulation technology becoming important in
preventing both, the gain and loss of heat through the building envelope. This work aims to
evaluate the feasibility of using inexpensive raw materials such as kaolin and waste material
such as seashells and banana peel for fabrication of the sustainable anorthite-based porous
ceramics for thermal insulation. Kaolin was used as a source of Al2O3 and SiO2, seashells as a
source of CaO whereas banana peel was used as a pore former. The phase composition, bulk
density, open porosity, compressive strength, microstructure, and thermal conductivity of the
ceramic samples, were analyzed. The obtained results showed that the variation of pore former (banana peel) content and sintering temperature was an effective way to control the
thermo-mechanical properties of the obtained anorthite ceramics. Samples with open porosity
(1.4 – 45%), compressive strength (>15 MPa), bulk density (1.87-2.62 g/cm3

AB  - YNbO4:xEu3+ powders (0.1, 0.25, 0.5, 0.75, 1, 3, 5, 7.5, 10, 15, 20 mol %) were synthesized by a solid-state reaction, after homogenization in a vibrational mill. All the samples crystallize in a monoclinic Fergusonite-beta-(Y) structure (C2/c space group), with 45–65 nm crystallite sizes and show a strong orange/red luminescence with 5D0 excited state lifetimes of around 0.6 ms. Photoluminescence emission spectra showed no concentration quenching within the examined concentration range. Judd–Ofelt intensity parameters show a slight increase with rising concentration, up to Ω2 = 8.13∙10−20 cm2, Ω4 = 2.67∙10−20 cm2, and Ω6 is concentration invariant with the 0.35∙10−20 cm2 value. Emission lifetimes of the 5D0 state are almost constant with ∼0.6 ms, and a slight decrease is observed with the highest concentrations. The intrinsic quantum yield of all the samples is about 0.5.
