AB  - Growing industrialization and non-renewable resource depletion have a huge impact on alternative clean up technologies  development, inducing investigation of the renewable, low-cost waste materials. Recently, lignocellulosic waste biomass,  generated at a large scale by different industries, appeared as an attractive feedstock worldwide, due to its abundance,  availability, multi-functionality and low cost. Since the fruits production has increasing trend all over the world,  generation of lignocellulosic waste such as fruit stones (that represent approximately 1/5 of the total fruit mass) became a great environmental threat. In order to minimize negative impact on the environment, avoid greenhouse gasses emissions  and help in resource depletion by its renewable nature, it is necessary to explore its performances regarding its wide  application potential. Thermo-chemical conversion of lignocellulosic biomass in oxygen limited conditions, in order to  get biochar, has received a lot of attention recently. The biochar production requires lower energy inputs and less  expensive technology compared to activated carbon (estimation is that production cost of activated carbon are six times  higher than biochar costs).  In this paper, waste peach stones biomass was effectively converted into biochar at 500 °C under inert (Ar) atmosphere.  Pyrolysis was performed in Nabertherm 1300 muffle furnace for residence time of 1.5 h, with a heating rate of 10 °C/min,  while Ar was circulated through the sample at a rate of 100 mL/min. The raw biomass (PS) and obtained biochar (PS-B)  with particle size 0.1 mm < dp < 0.5 mm, were characterized by Scanning Electron Microscopy (SEM), Fourier transform infrared spectrometry (FTIR) and Raman spectrometry to understand physicochemical changes which have been occurred  after pyrolysis. SEM analysis revealed the increased surface area due to the visible augmentation of pores and roughness.  FTIR analysis showed that many bands present in native biomass cannot be observed in biochar, due to the conversion or  removal of the most of the functional groups. Prominent bands have confirmed presences of aromatic compounds in  biochar: at 1592 cm−1 (C=C bond stretching derived from aromatic rings in the lignin), 1030 cm-1 (alcohol C-O stretching  vibration) and in the region 900 to 700 cm−1 (originating from aromatic compounds). These finding are in accordance  with results from Raman analysis, where D and G bands (at 1350 cm-1 and 1580 cm-1 respectively), indicate the presence  of poly-aromatic hydrocarbons. Thermo-chemically modified biomass like this has a great application potential: as a pollutants sorbent, biofuel, soil  amendment, biocarriers, and in construction and electronic industries.

AB  - The removal of organic and inorganic sulfur from the Bogovina Basin subbituminous coal by electrochemical redox reactions was performed. The effect of presence of active bromine species on the desulfurization process was monitored. The desulfurization was performed in inorganic acidic solutions that contained different bromide concentrations and in pure acid solution. To 
determine the optimal conditions for the desulfurization process, polarization curves were 
recorded in three different electrolytes: 0.1 M H2SO4, 0.1 M H2SO4 + 0.01 M KBr, and 0.1 M 
H2SO4 + 0.1 M KBr using graphite and dimensionally stable anode (DSA) electrodes as the 
anode, while in all cases stainless steel S31603 electrode was used as cathode. By analyzing the 
results obtained from the polarization curves, 0.1 M H2SO4 and 0.1 M H2SO4 + 0.1 M KBr were 
chosen as the most suitable electrolytes. Also, it was found that the DSA anode showed better 
results in terms of energy efficiency of the process compared to the graphite anode and therefore
it was selected for the coal desulfurization process. It is considered that finely suspended coal 
particles in an electrolyte can behave according to bipolar electrochemistry. Coal was treated 
for 4 hours in two selected electrolytes. The suspension was sampled at different times up to 240 
min from the beginning of the process. Sulfur content in coal was determined by elemental 
analysis. The results showed that the sulfur content decreases faster in the case of the electrolyte 
containing KBr, i.e. that the desulfurization effect is significantly better than in the case of the 
system containing only H2SO4. It can be concluded that active bromine species accelerate the 
desulfurization process and thus improve energy efficiency.

AB  - Fluorapatite (FAP) crystals have drawn significant interest over the last few decades as important hosts matrix for optically active trivalent rare earth ions, due to the strong crystal field splitting and large transition cross-sections. Nano-sized FAP particles doped with rare earth ions have been extensively studied as luminescent materials for biomedical applications for cell labeling and bioimaging, as well as antimicrobial agents for therapeutics.Fluorapatite nanoparticles doped with praseodymium ions (Pr3+) were prepared by the co precipitation method and characterized. The different number of Pr3+ (4f2) transitions in the ultraviolet and visible parts of the spectrum was investigated by photoluminescence spectroscopy. Multivariate Curve Resolution–Alternating Least Squares (MCR-ALS) analyses of fluorescence spectra and ab initio calculation indicated that Pr3+ ions are preferentially substituted Ca2 (6h) sites in FAP lattice. In addition to the substitution of cations, there is also the substitution of anionic species such as OH-, CO32-, and NO3-, which are confirmed by the CHNS method. The obtained samples were tested as bioimaging and antibacterial agents and can potentially be used for further biomedical research.

AB  - Nickel pollution of water induces several problems for the environment. The purpose of this paper was toinvestigate the adsorption of Ni2+ ions on fabricated biomembranes. The proposed adsorbent was preparedfrom epoxy and amino-functionalized waste cellulose fibers, able to participate in cross-linking with aminoacid lysine - wCell/Mn-Fe_LDH. The prepared material underwent preliminary structural characterizationby Fourier-transform infrared spectroscopy. In a batch system, the influence of pH, contact time,temperature, and initial concentration on adsorption efficiency was investigated. The effectiveness of themembrane was demonstrated by acceptable adsorption capacities of 40.49 mg g-1 obtained for Ni2+ at 45°C.The kinetic study, using the Weber-Morris model, indicates intraparticle diffusion as the rate limiting step.Adsorption mechanism physisorption was proposed based on thermodynamic behaviors. The outcomesdemonstrated that environmentally friendly sustainable technology has been successfully developed.

AB  - Titanium alloys are widely employed in various fields, particularly in biomedical engineering, due to their mechanical  and corrosion resistance properties combined with good biocompatibility. The modulus of elasticity is a distinguishing  feature of this group of materials compared to others used for similar purposes. A database of approximately 238 titanium alloys free of toxic elements was compiled for this study. The influence of different factors (such as alloy element  proportions, density, and specific heat) on the modulus of elasticity was predicted using four methods: support vector machine, XGBoost, Neural Network, and Random Forest. The Random Forest mean absolute error (MAE) of 7.33 GPa, falls within the range of experimentally obtained absolute errors in the literature (up to about 11 GPa). A strong correlation (R2 = 0.72) was observed between experimental and predicted data. Lastly, specific alloying element regions were identified for the modulus of elasticity, which can be used to design new biocompatible titanium alloys in the future.

AB  - Worldwide pollution induces a negative impact on the complete environment. Modern societies are becomingmore involved in developing and implementing climate change adaptation policies as a result ofthe enormous hazards that climate change poses to human safety worldwide. One of the biggest problemsthat highly affects climate change is plastic pollution. Also, the utilization of a linear economy prevents theopportunity of solving mentioned problem. Hence, a major component of the strategy for tackling plasticpollution and trying to decrease global weather changes is an implementation of a circular economy. Plastichas to be reduced, reused, and recycled since its widespread consumption has put environmental protectionat risk. PET, also known as polyethylene terephthalate, is a prominent polymer material used forthe production of packaging, particularly plastic bottles. The majority of PET-based products are madeusing raw materials supplied from fossil fuels. However, methods based on biobased materials and recycling-modified products for obtaining novel products from waste PET have fewer greenhouse gas (GHG)emissions than the traditional method. Therefore, the subject of this paper is the innovative technology forthe fabrication of materials by PET recycling. Obtained monomer units - glycolysates were acquired by PETdepolymerization by inducing greener solutions. The resulting glycolysate was structurally modified withmaleic anhydride and finally with 2-octanol to obtain a novel plasticizer. The physicochemical characterizationof the obtained plasticizer, performed by infrared spectroscopy with Fourier transform (FTIR) andNMR spectroscopy, confirmed structural modifications. The mechanical characteristics of the final productwere tested after the plasticizers had been combined with bitumen at a range from 1 to 10 wt.% concentration.In addition, other PET recycling techniques will be presented and discussed. By comparing them,it will be determined which technique is most suitable for recycling with the smallest carbon footprint. Thesecond purpose of the research is to evaluate and contrast the financial and ecological implications of recyclingPET in comparison to other types of waste and renewable energy sources.

AB  - Cobalt–chromium–molybdenum (CoCrMo) alloys are known for medical use due to their biocompatibility, corrosion and  wear resistance. The chemical and phase composition, as well as microstructure of the alloy directly affect the mechanical  properties. In this investigation, CoCrMo alloy samples were obtained by vacuum precise casting. The procedure of  melting and casting process as well as their parameters are given. Molds fabricated of copper, gray iron, steel, ceramics  and graphite were used during the casting process. In this way, the cooling rate influence on the obtained microstructure  was examined. Besides, different casting temperatures (1400°C, 1450°C and 1500°C) were applied for each kind of mold.  After metallographic preparation, the microstructure was examined on the cross section of samples by optical microscopy.  The obtained results show that by increasing the cooling rate, the microstructure of samples become finer and more  homogeneous.

AB  - Even though it has been in use for a very long time, the high chromium white cast iron (HCWCI) still triggers scientists  due to its outstanding wear resistance. Besides its well-known as-cast usage, it can be used as a coating material, as well.  HCWCI owes this feature due to the presence of carbides in microstructure, which depends on the composition and heat  treatment regime. This investigation was conducted on two HCWCI alloys, where in addition to chromium, the second  important alloying element is molybdenum (Mo). Apart from other alloying elements, HCWCI_1 is alloyed with 24.48%  Cr and 1.32% Mo, while HCWCI_2 contains 14.11% Cr and 2.47% Mo. The comprehensive microstructural  characterization was carried out on as-cast samples and samples obtained after quenching (at -196oC) and/or quenching  followed by tempering (at 250oC). Important microstructure indicators are: the stability of austenite, the ratio of microconstituents (especially different types of carbides), as well as their arrangement and morphology, so they are revealed  and discussed in relation to the influencing mechanical properties.

AB  - Cotton-based membranes, due to their exceptional biocompatibility and sustainability,have attracted considerable attention in various applications, especially in the field of bio andgreen technologies. This study investigates the biodegradation potential of cotton membranesmodified with TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) radical and citric acid (CA),with the aim of improving their properties and facilitating environmentally friendly disposal.TEMPO radicals, in conjunction with the crosslinker citric acid, are incorporated into thecellulose structure through a novel modification process. The citric acid component acted as aplasticizer, increasing the amorphous parts of the cellulose and promoting enzymatic attack.The TEMPO radical, with its nitroxyl group, contributed to the oxidation of cellulose, furtherfacilitating biodegradation.The biodegradation aspect of these modified membranes was investigated incontrolled environmental conditions (Soil Burial test), simulating natural scenarios (humidity,influence of enzymes, and bacteria). Biodegradation parameters such as weight loss,structural changes, and degradation kinetics were examined during 90 days. Characterizationof the structure was performed using FTIR and SEM methods.Our findings suggest that cellulosic membranes possess complete (100%)biodegradability after 70 days compared to unmodified membranes. Obtained result shedlight on the potential of membranes modified in this way as sustainable and biodegradablealternatives in various applications. The results emphasize their ecological nature and abilityto reduce environmental stress. Such cellulose-based materials promise a much greener futurein biotechnology, healthcare, and environmental protection.

AB  - The pattern recognition approach, explored by this study, applies the principal component
analysis (PCA) as the most widely used statistical method with the aim of assessing the initiation
and propagation of the cracks and defects that appear on the surface of material exposed to the
cavitation. The experiment was performed in four stages: (a) synthesis of two ceramic materials
(cordierite and zircon); (b) subjecting the samples to the cavitation; (c) using image analysis
software for collecting the data about morphological characteristics that describe defects; (d)
principal component analysis as a pattern recognition tool in order to characterize the defects at
the material surface. Besides that, according to standard, cavitation erosion was monitored by
determining material mass loss during the cavitation. Large experimental datasets collected from
morphological descriptors by image analysis are multivariate and difficult to interpret, thus are
processed by principal component analysis as the most informative technique for extracting
possible differences. The performed approach proved that this method has a great potential for
better assessment of induced defects by proper distinguishing among them at different levels and
that can be considered a very efficient and cost-effective one.

In the last fifty years, synthetic polymers have been used for the modification of concrete, but also for the production of concrete. In recent decades, sulfur concrete has been an interesting product that can be used mainly in low-rise construction due to its characteristics. In this work, we used the starting mixture  for  the  preparation  of  sulfur  concrete  (sand,  elemental  sulfur  with  the addition of modified sulfur and fillers) heated to a temperature of 120 ºC to 170 ºC and  homogenized.  The  results  of  previous  research  on  the  production  of  sulfur concrete showed that the density of the obtained product changes depending on the type  as  well  as  the  amount  of  filler  added  to  the  basic  mixture  based  on  raw materials. Talc, microsilicon, plate alumina and fly ash were used as fillers. The amounts of fillers were 0%, 1%, 3%, 5%, 7% and 10%.

AB  - Poly(methyl methacrylate) (PMMA) has a broad spectrum of uses, especially in medical applications. The role of fine-grained alumina particles of PMMA composites was investigated in this study. The composites were based on PMMA modified with dimethyl itaconate (DMI) as a matrix and alumina particles (Al2O3) and alumina doped with iron (Al2O3-Fe) modified with
3-aminopropyl-trimethoxysilane (AM) and flax oil fatty acid methyl esters (biodiesel) as reinforcements. Three particle sizes were measured (~0.4, ~0.6 and ~1.2 μm). The highest thermal conductivity values were measured for the composite 5 wt.% Al2O3-Fe-AM. With the addition of 3 wt.% Al2O3-AM to the PMMA/DMI matrix, mechanical properties were improved (tensile strength, strain, and modulus of elasticity). An artificial neural network model based on the Broyden-Fletcher-Goldfarb-Shanno iterative algorithm was investigated for prediction of thermal conductivity and mechanical properties of the composites showing satisfactory results. This is relevant for applications for optimization of dental materials to produce dentures, which were exposed to variations in temperature during the application.

AB  - The aim of this research was to obtain an initial characterization of  the  BaO  and  TiO2components,  as  well  as  to  conduct  preliminary research into the possibility of activating the initial components in order toobtain barium titanate. Chemical and X-ray structural analysis of the initial components  was  performed.  In  order  to  determine  the  possibility  of applying a mechanochemical activator and the activation time in which the first intermediate compounds were formed by the activation of the starting substances, the system was activated for 30 minutes. After this, an X-ray structural analysis was performed and certain changes in the crystal lattice of  the  starting components  were  made. X-ray  structural analysis  showed that  during  grinding,  amorphization  of  the  initial  components  occurred, which is the first stage in the process of obtaining titanate, as well as the presence  of  a  small  amount  of  barium  titanate,  which  is  indicating  the presence of an intermediate compound in the process of finally obtaining barium titanate.

AB  - In this study, luminescence and antibacterial behavior of pure fluorapatite (FAp) and praseodymium-nitrate-carbonate co-doped fluorapatite (PrNCFAp) nanopowders were investigated. Uniform nanopowders were synthesized by precipitation reaction followed by centrifugation and systematically characterized by XRD, FTIR, SEM–EDS, TG and PL methods. XRD analysis revealed the formation of hexagonal FAp crystals, and FTIR spectra indicate the presence of nitrate (NO3−) and carbonate (CO32−) species. SEM analyzes confirm agglomerates composed of irregular nanometer-sized spheres. Emission of FAp nanopowder occurred in the violet-blue region of the visible part of the spectrum, with redshift to the blue-green color region when Pr3+, NO3− and CO32− co-doped in the lattice. Analysis of luminescence spectra by MCR-ALS method extract three fluorophores from the PrNCFAp sample and showed simultaneous existents of emission-reabsorption-emission between dopants in FAp lattice. Antibacterial activity against pathogen Staphylococcus aureus was investigated before and after treatment of nanopowders by UVA radiation of 365 nm. Nanopowders irradiated with UVA compared to non-irradiated reduced Staphylococcus aureus by 84.9% for PrNCFAp and 33.3% for FAp in the first 0.5 h of contact, and 76.1% and 42.9% after 24 h of contact. In addition, the obtained luminescent nanomaterials showed a low degree of hemolytic activity and could potentially be candidates for further research in dentistry.

AB  - Two Co(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole (HL1 ligand, (E)-2-(1-(thiazol-2-yl)ethylidene)hydrazine-1-carbothioamide) and the condensation product of 2-acetylpyridine and Girard's P reagent (HL2Cl ligand, (E)-1-(2-oxo-2-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)ethyl)pyridin-1-ium chloride) have been synthesized and characterized based on the results of single-crystal X-ray diffraction, NMR and IR spectroscopy and elemental analysis. Cobalt(III) complex with HL1 ligand, [Co(L1)2]BF4⋅H2O (1), is bis octahedral complex in which two deprotonated ligand molecules coordinate in a mer arrangement through two NNS sets of donor atoms. In cobalt(III) complex with HL2Cl, [Co(L2)(N3)3] (2), the ligand is coordinated in deprotonated, formally neutral, form to Co(III) ion in tridentate fashion through NNO set of donor atoms, and the other three coordination sites of a monokis octahedron are occupied by meridionally coordinated azide anions. DFT calculations were performed to elucidate coordination preferences of these ligands toward Co(III) ion.

AB  - Infant nutrition is essential for their growth and development. This research aims to determine the total antioxidant capacity of the infant food for preterm infants and indicate adequate methods for testing the quality and biological value of milk and infant food. The total antioxidant capacity (TAC) was determined in human milk and an infant formula for premature infants. The determination of the total antioxidant capacity was made using cyclic and differential pulse voltammetry, potentiometry and electron paramagnetic resonance spectroscopy. The results of three comparative electrochemical methods indicate that human milk has a higher antioxidant potential compared to infant formula, which contributes to better physiological development of the child. Fenton-based electron paramagnetic resonance spectroscopy method provides additional insight into TAC analysis, whereby a carbon-centered radical and an ascorbyl radical are formed in infant food. All methods can be used to determine TAC, since the results obtained individually with each method follow the same trend.

AB  - The mutual interaction of metal ions (lead, zinc and copper) on removal efficiency in binary and
ternary systems, by biosorbent based on alkali treated apricot shells (Prunus armeniaca L.) was
examined. The evaluation was done in batch system at two metals concentrations: 0.2 and 0.5mmol/
dm3. Tested biosorbent exhibited preferential uptake of lead in a multimetal systems. It is evident that mutual inhibition exists in all multimetal systems, but systems containing lead ex-hibited extreme inhibition toward copper and zinc ions. Process of sorption depends not only on specific chemistry of each metal, their affinity toward binding sites and the type of metal binding onto biosorbent, but also on sorbent chemical and morphological characteristics. In multimetal systems, tested sorbent showed preferential sorption orders: Pb (II)>Cu (II)>Zn (II).

AB  - The main objectives of this research were to (i) investigate the concentration; (ii) characterize the distribution; (iii) determine the sources apportionment; (iv) estimate environmental and health risks of heavy metals in soil from mountain beech forest. A total of 76 soil samples from 20 pure beech forest stands from Bosnia and Herzegovina (BA), Bulgaria (BG), Check Republic (CZ), Germany (DE), Italy (IT), Poland (PL), Romania (RO), Serbia (RS), Slovakia (SK), Slovenia (SL), and Spain (ES) were collected. The content of major elements was measured by X-ray fluorescence spectroscopy (XRF). The content of heavy metals was measured by inductively coupled plasma–optical emission spectrometry (ICP/OES). Heavy metals had a specific concentration range, which followed in soil samples from depth 0–40 cm the common order (low to high): Hg < Cd < As < Co < Pb < Ni < Cu < Cr < Zn, and from depth 40–80 cm: Hg < Cd < As < Pb < Co < Ni < Cu < Cr < Zn. The grouping of the examined parameters according to rock types, soil types, and localities indicated the separation of carbonate rocks from other substrates, luvisol, and rendzina from other soil types, and samples from BA, SL, and IT from other localities. According to sources apportionment As, Pb and Zn are of anthropogenic origin, Cd, Co, Cr, and Ni are of geogenic origin, while the middle position of Cu and Hg indicates a combined contribution of both sources. Elements Cd and Hg indicated severe to extremely severe enrichment with a mean value of 24.3 and 70.6, respectively. Based on the determined values Ni, Cr, As and Cd do not pose a health risk.

AB  - Cationic surfactant - octadecyldimethylbenzyl ammonium chloride (ODMBA) was used for modification of the three natural raw materials - bentonite, kaolin and zeolite. Adsorption of ODMBA by minerals occurred via ion exchange of inorganic cations on minerals with surfactant. Organomodified minerals - organobentonite (OB), organokaolin (OK) and organozeolite (OZ) were studied as adsorbents for removal of two non-steroidal anti-inflammatory drugs - ibuprofen (IBU) and diclofenac sodium (DS) at pH 7. For all systems, the pseudo-second order model showed the best correlation to kinetic experimental data. In all cases, the positive values of Delta H degrees indicated that the adsorption of both IBU and DS by organomodified minerals was endothermic in nature. Equilibrium data were better described by the Freundlich isotherm model, pointing to adsorbent heterogeneous active sites for adsorption. Under applied experimental conditions, the highest adsorption of both drugs was achieved by OB, while much lower capacities were observed for OK and OZ. Nonlinear isotherms and physicochemical characterization of organomodified minerals after drugs adsorption suggested complex mechanism consisting of hydrophobic interactions between hydrophobic part of the drugs and surfactants alkyl chains, electrostatic interactions of anionic forms of IBU and DS with the cationic "head" of ODMBA, as well as anion exchange of counterion ions from ODMBA micelle and anionic forms of both drugs. Adsorption of both IBU and DS was strongly dependent on the amount of ODMBA ions in the minerals.
